▼ Reduced milk fat still represents an issue on many dairy farms. Inhibition of milk fat synthesis is normally caused by bioactive trans fatty acids (FA) formed during ruminal biohydrohenation (BH), and this condition is called BH-induced milk fat depression (MFD). Contemporary lactating diets rich in corn feeds increase risk of BH-induced MFD. This may be because corn is rich in linoleic acid (LA), the parent compound for the formation of trans FA the cause MFD. This dissertation first demonstrates that considerable variation in LA concentration exists amongst commercially available corn hybrids. The variation was mainly attributed to hybrid and selection should focus on LA as a percentage of total FA, as this trait was not correlated with other nutrients important to the cow. Secondly, it was demonstrated that MFD is a multifactorial condition and that important interactions exist between dietary risk factors, individual cow effects, and feed additives. Supplementation with the methionine analog 2-hydroxy-4-(methylthio)butanoate (HMTBa) maintained higher milk fat when high producing cows received diets with increased risk of BH-induced MFD. Low producing cows did not undergo MFD, nor did their milk fat respond to HMTBa supplementation. Thirdly, it was demonstrated that an in vivo BH assay utilizing a perturbation tracee approach performed by bolusing FA through the rumen cannula was appropriate to assess the rate and extent of ruminal unsaturated FA BH as well as flux through specific BH pathways. Lastly, decreased BH-induced MFD with HMTBa supplementation was replicated and using the in vivo assay developed it was shown that the mechanism by which HMTBa prevents ruminal formation of bioactive trans FA is, at least in part, due to increased BH capacity. In conclusion, this dissertation presented opportunities to combat MFD by selection of corn hybrids low in LA and supplementation with HMTBa. Additionally, this work sets the framework for further research on milk fat by presenting an experimental design that efficiently investigates the interactions between risk factors and a novel in vivo assay appropriate to study ruminal BH.

▼ The objective of these studies was to investigate the milk fat synthesis regulation by transcription factors. In the first study, bovine mammary epithelial (MAC-T) cells were treated with sterol regulatory element binding protein-1 (SREBP-1) specific siRNA. The mRNA and protein expression of SREBP-1 were decreased by more than 90% by siRNA. Fatty acid (FA) synthesis, uptake, and selected lipogenic enzyme expression were reduced in cells treated with SREBP-1 siRNA. Therefore, SREBP-1 plays an important role in integrated regulation of lipid synthesis in MAC-T cells through regulation of key enzymes. In the second study, MAC-T cells treated with hormones or FA were transfected with luciferase reporter constructs containing response elements for SREBP-1, peroxisome proliferator-activated receptor Î³ (PPARÎ³), or liver X receptor (LXR). The activation of PPARÎ³ and SREBP-1 were stimulated by insulin and insulin combined with leptin, respectively. Trans-10, cis-12 conjugated linoleic acid (CLA) inhibited SREBP-1 activation, and this inhibition was not attenuated by insulin and leptin. Neither trans-10 nor cis-12 double bond inhibited SREBP-1 activation. Taken together, trans-10 and cis-12 double bonds need to be conjugated in CLA to reduce SREBP-1 activation and this inhibition cannot be overcome by insulin and leptin combination in MAC-T cells. In the third study, lactating dairy cows were intravenously infused with 0.625 g/h trans-10, cis-12 CLA for 14 h. We confirmed the appearance of trans-10, cis-12 CLA in the milk of CLA treated cows. Milk and component yield were not affected by the CLA treatment. The desaturation of stearic acid was reduced by CLA. The mRNA and protein expression of transcription factors or lipogenic enzymes were not affected by trans-10, cis-12 CLA. DNA-binding activities for PPARÎ³ and LXR and the activation of SREBP-1 to its mature form were not changed by the treatment. The infusion time in this study was probably too short to induce any changes in transcription factors and lipogenic enzymes. We confirmed DNA-binding activities of PPARÎ³ and LXR in bovine mammary gland. Overall, a prominent role for SREBP-1 in mammary epithelial cell lipid synthetic pathways was described and regulation of transcription factor activation by trans-10, cis-12 CLA was specific to SREBP-1.

▼ "Summary": Efficient fat digestion is an essential part of neonatal development. In this respect, it is noteworthy that the process by which infants digest fat differs from that in adults; key differences include the immaturity of the pancreatic function and elevated gastric pH. The digestion of emulsified lipids may accordingly be rendered less efficient in ambient conditions in the infant gastric lumen. For example, it may be postulated that covariation in optimal conditions of proteolytic and lipolytic digestion may differently affect the digestion and disruption of the droplet membrane, the interfacial accessibility of lipase and the subsequent fatty acid production. Differences between formulated emulsion structures may therefore influence the rate of digestion; previous human studies have indicated that infants digest formula feeds more slowly than they do breast milk (Splinter and Schreiner, 1999). To further explore this observation, the lipid digestion of native biological milk (human breast milk), commercial infant formulae (liquid and powder), and model emulsions (Intralipid containing lactoferrin) were investigated in an in vitro gastric system. The aim was to gain a better understanding on the changes in emulsion structure and fat digestibility with various interfacial layers and pH environments under simulated gastric conditions. The introduction and a rationale for the focus of this thesis are shown in Chapter 1. Chapter 2 gives a critical overview and review of the literature pertaining to this thesis, and presents possible explanations of how the properties of milk fat globules and their membranes are related to the digestion outcome in the digestive system of infants. The review also examines the effects of physicochemical factors on emulsion stability. Then, Chapter 3 presents the general materials and methods used in the experimental work. The first experimental design is described in Chapter 4. This chapter compares the characteristics and physicochemical properties of different types of milks. Infant formulae are prepared from cow’s milk and designed to mimic human milk as much as possible. However, even with the advances of technology, there are still differences observed between the breast milk and commercial infant formulae. Therefore the microstructure, droplet size and droplet charge of these different types of milk (human milk, raw cow’s milk, commercial liquid formulae and commercial powder formulae) were examined before studying the emulsion digestibility under simulated infant physiological conditions. Chapter 5 gives a description on how digestion affects emulsion structure of a typical formula emulsion at different pH levels (25.5) in an in vitro system that replicates the shear rates that would normally be encountered in the infant stomach. The system is designed to simulate infant gastric conditions using different combinations of porcine pepsin and fungal lipase (Rhizopus oryzae). Thus, digestion in the presence and absence of proteolytic…

▼ Research conducted for this dissertation had three goals; 1) determine if CLA can induce milk fat depression immediately postpartum, 2) determine if CLA can alter energy availability, 3) determine the mechanism behind the mammary gland's decreased sensitivity to CLA immediately postpartum. The first study provides strong evidence indicating CLA can decrease milk fat synthesis immediately postpartum, but the dose required is approximately 3x greater than in established lactation. This trial also provided evidence that CLA can alter energy status, as CLA decreased days to EBAL nadir by nearly 5 days. This is relevant as recovery of EBAL from its lowest point provides an important signal for initiating ovarian activity and days to nadir is highly correlated with days to first ovulation. Study two was designed to determine if CLA induced milk fat depression could improve energy status during heat stress. Rumen-inert CLA reduced milk fat synthesis, and was able to improve energy availability, but did not increase milk yield or yield of other milk components. Although production was unchanged in this study, the study did provide further evidence that rumen-inert CLA can alter energy availability. Study three utilized intravenous infusion of CLA in cows in mid and early lactation to determine the mechanism for the mammary gland's decreased sensitivity in early lactation. It is postulated that increased fatty acid oxidation and subsequent enhanced levels of circulating NEFA present during the transition period competitively prevent adequate CLA uptake by the mammary gland. In the current study, trans-10, cis-12 CLA concentration in milk was not different between early and established lactation, while milk fat yield was drastically reduced on d 4 and 5 of trans-10, cis-12 CLA infusion in mid lactation cows, but unaltered in early lactation. Further, NEFA levels were nearly 3 fold higher in early lactation than in mid lactation, providing further evidence that increased circulating NEFAs in early lactation are unlikely to be the source of the mammary gland's decreased sensitivity during this time. Do to the variation in gene expression observed in this trial, we were unable to make any definitive conclusions as to the sensitivity of the expression of genes involved in milk lipid synthesis to CLA in early vs. mid lactation.

▼ The milk fat globule membrane (MFGM) obtained from bovine milk is a source of bioactive compounds. In this research, the hypothesis that the MFGM possesses anticarcinogenic capacity and immune modulatory properties was tested, along with the hypothesis that processing history of the fat globules will affect the bio-functionality of the MFGM. Throughout all experiments, lipopolysaccharide (LPS) was minimized by extracting the milk using a catheter, working under aseptic conditions and avoiding contamination via reagents. To study the anticarcinogenic capacity, native MFGM was tested in vitro using two colon adenocarcinoma cell lines (HT-29, Caco-2). Stimulated cells showed a dose-dependent decrease in cell proliferation, starting at very low concentrations (1 μg/mL based on protein) and its efficiency was comparable or even superior to the commercial anticarcinogenic drugs melphalan and C2-ceramide. Cytotoxicity and apoptosis were found to be mechanisms responsible for this bioactivity, as shown by the lactate dehydrogenase enzyme activity and the increase in caspase-3 production. MFGM- immune modulatory capacity was also tested by studying its effects on splenocyte proliferation, apoptosis and cytokine production. While splenocyte proliferation was not affected when the MFGM isolate was used alone, it suppressed cell division in the presence of polyclonal activators (LPS, Concanavalin A) used to simulate inflammatory conditions. Cytokine production suggests inhibition of the splenocytes’ activation process as the mechanism behind its bioactivity. Milk heating caused a significant decrease in bioactivity, indicating that protein interactions and denaturation as well as the structural changes caused by this treatment, directly affect the MFGM bio-functionality. Partial hydrolysis (by trypsin and phospholipase-A2) caused a similar effect, suggesting that not only the phospholipids are involved in the anticarcinogenic capacity, but also, the complex mixture of proteins which form part of the MFGM complete system. In summary, the bioactivity of the MFGM extracted from milk is not limited to its anticarcinogenic but also to its immune regulatory ability, by helping control the response of the immune system when inflammatory conditions arise. However, pre-treatment of the raw material greatly affects this bioactivity, suggesting that greater care may be needed in processing of fat globules to maintain such important characteristics of their components.

O fornecimento de Ãcido linoleico conjugado (CLA) em uma forma inerte no rÃmen tem demonstrado efeitos consistentes sobre o teor de gordura e perfil de Ãcidos graxos do leite. Contudo, poucos estudos utilizaram esse suplemento na forma desprotegida da biohidrogenaÃÃo ruminal. Os objetivos deste estudo foram avaliar os efeitos do fornecimento de um suplemento de CLA desprotegido da bio-hidrogenaÃÃo ruminal (29,8% de cis-9, trans-11 e 29,9% de trans-10, cis-12) sobre parÃmetros produtivos, perfil de Ãcidos graxos do leite e no balanÃo energÃtico de cabras leiteiras. Vinte cabras Toggenburg foram utilizadas em um delineamento cross-over e receberam os seguintes tratamentos: a) Controle: 30 g/d de Megalac-EÂ e; B) CLA: 30 g/d de um suplemento de CLA. Os suplementos lipÃdicos foram misturados a um concentrado Ã base de milho (1 kg/d) fornecidos duas vezes ao dia em porÃÃes iguais, logo apÃs as ordenhas da manhÃ e da tarde. Cada perÃodo experimental consistiu de 14 dias, separados por um perÃodo de seis dias para minimizar efeitos residuais. O tratamento CLA reduziu a concentraÃÃo e a produÃÃo da gordura do leite em 13,9 e 13,3%, respectivamente.O tratamento reduziu ainda a concentraÃÃo e produÃÃo de sÃlidos totais em 4,8 e 4,6%, respectivamente. O tratamento CLA reduziu o consumo de forragem em 6,6%.O peso vivo e a produÃÃo de leite nÃo diferiram entre tratamentos, com mÃdias de 39,9 Â 0,5 kg e 2,6 Â 0,1 kg/dia, respectivamente. Quando os Ãcidos graxos foram agrupados conforme a origem, houve uma reduÃÃo de 13% naqueles derivados da sÃntese âde novoâ (<C16), um aumento de 15,5% nos prÃ-formados oriundos da circulaÃÃo (>C16) e uma reduÃÃo de 9,45% para os originÃrios de ambas a fontes (C16:0 e C16:1). A suplementaÃÃo com CLA reduziu os Ãndices de dessaturase do C14:1/C14:0 em 31,7%, do C16:1/C16:0 em 5,9%, do C17:1/C17:0 em 25,2%, do C18:1/C18:0 em 25,5% e do CLA cis-9, trans-11/trans-11 C18:1 em 5,2%. As concentraÃÃes de CLA trans-10, cis-12 e CLA cis-9, trans-11 foram 1376 e 29,2%maiores nas cabras que receberam CLA, respectivamente. As concentraÃÃes de C18:1 trans-10 e C18:1 trans-11 foram elevadas em 134,1 e 39,9%, respectivamente. A secreÃÃo de CLA trans-10, cis-12 aumentou 993,42% no tratamento CLA. O tratamento CLA reduziu a concentraÃÃo de Ãcidos graxos nÃo esterificados (AGNE) no plasma sanguÃneo em 22,4%. O balanÃo energÃtico dos animais melhorou no tratamento CLA em 123,8% quando comparado ao tratamento controle

Feeding trans-10, cis-12 CLA has resulted in milk fat depression in dairy cows, ewes and goats. However, its effects in goats are less understood in comparison with other ruminant species. Therefore, the objective of the present study was to evaluate the effect of increasing doses of a rumen unprotected trans-10, cis-12 CLA supplement on milk production, secretion of milk components and milk fatty acid profile in dairy goats. Eight Toggenburg non pregnant goats (135 Â 21 DIM) were used in a duplicate 4 x 4 Latin Square design (12-d treatment periods separated by 6-d intervals) according to the order of lactation (primiparous and multiparous). The animals within each group were randomly assigned to the following dietary treatments: CLA0: 45 g/d of Megalac-E; CLA15: 30 g/d of Megalac-E+15 g/d CLA; CLA30: 15 g/d of Megalac-E+30 g/d of CLA; CLA45: 45 g/d of CLA. The lipid supplements were mixed in the concentrate and fed individually to the animals after morning and afternoon milkings. The CLA supplement (Luta-CLA 60) had 29.9% of trans-10, cis-12 CLA as methyl esters, resulting in doses of 0, 4.48, 8.97 and 13.45 g/d of this CLA isomer for CLA0, CLA15, CLA30 and CLA45 treatments, respectively. Dry matter intake, milk yield, content and secretion of milk protein and lactose, body condition score and body weight were unaffected by the dietary treatments., The comparison of milk fat content and yield observed on the last day of each treatment period (d 12) with those found on day 0 showed that CLA0 treatment increased the milk fat content. Thus, milk fat content and yield on day 0 were considered as 100%. The CLA15, CLA30 and CLA45 treatments reduced milk fat yield by 8.1, 26.1 e 32.7% and milk fat content by 4.5, 21.5 e 28.3%, respectively. The increase in dietary trans-10, cis-12 CLA dose reduced the concentration of milk fatty acids arising from de novo synthesis and increased the concentration of those derived from blood circulation. However, the milk secretions of both classes of fatty acids were reduced linearly as the CLA dose increased. The increase in dietary trans-10, cis-12 CLA also caused a linear reduction in milk fat C14:1/C14:0, C16:1/C16:0, C17:1/C17:0 and C18:1/C18:0 dessaturase indexes. Milk fat trans-10, cis-12 CLA content and secretion increased in goats fed increasing doses of trans-10, cis-12 CLA, which, corresponded to transfer efficiencies from diet to milk of 1.18, 1.17 and 1.21% for CLA15, CLA30 and CLA45 treatments, respectively. The energy balance (EB) increased linearly in goats fed increasing doses of trans-10, cis-12 CLA

O fornecimento de CLA trans-10, cis-12 atravÃs da dieta tem resultado na depressÃo da gordura do leite de bovinos, ovinos e caprinos. No entanto, os seus efeitos em caprinos sÃo menos compreendidos perante as outras espÃcies de ruminantes. Assim, o objetivo do presente estudo foi avaliar o efeito de doses crescentes de CLA trans-10, cis-12 desprotegido da bio-hidrogenaÃÃo ruminal sobre a produÃÃo, secreÃÃo dos componentes e perfil de Ãcidos graxos do leite de cabras…

▼ The present study examined the effects of heat treatment, high pressure (HP) treatment or combined heat and HP treatments, either before or after homogenization, on recombined milk systems. The main focus was to explore the changes induced by these treatments on the surface layers of recombined fat globules, milk proteins and rheological properties of acid gels. Heat treatments caused denaturation of whey proteins; the degree of denaturation was dependent on temperature, holding time and to a lesser extent on the placement of heat treatment. Recombined milks that underwent heat treatment before or after homogenization had similar levels of whey protein denaturation. The amounts of caseins and denatured whey proteins adsorbed on the surface of fat globules of recombined milk heated before homogenization were significantly lower than those heated after homogenization, indicating different interaction mechanisms in these two systems. Increases in treatment pressure used in HP treatment resulted in decreased amounts of caseins, while whey proteins adsorbed onto the surface layers of fat globules increased. This was probably due to the dissociation of casein micelles under HP treatment and the interactions between HP-induced denatured whey proteins and casein particles on the surface layers of fat globules. Combined heat and HP treatments induced changes on adsorbed caseins and whey proteins on fat globule surface layers. HP treatment induced additional denaturation of whey proteins in heated milks, resulting in slightly increased amounts of denatured whey protein adsorbed onto the surface layers. Gelation pH, final G? and yield stress values of acid gels prepared from recombined milks heated before or after homogenization were dependent on temperature, holding time and the placement of heat treatment. These changes were attributed to the extent of denaturation of the whey proteins and their interactions with casein particles adsorbed onto the fat globule surface and in the serum. Differences in acid gels prepared from recombined milks heated before and after homogenization were attributed to the relative proportions of caseins and whey proteins at the surface layers of fat globules resulting in different interactions with protein strands in the gel network. The acid gels prepared from recombined milks HP-treated either before or after homogenization had shorter gelation times, higher gelation pH, final G? and yield stress values compared with untreated recombined milk and the effects were dependent on treatment pressure, temperature, holding time and the placement of HP treatment. The denaturation of whey proteins and their interactions with casein particles were responsible for these changes. In HP-treated recombined milks the proportions of caseins and denatured whey proteins adsorbed onto the surface layers of fat globules had significant effects on the acid gel structure. When HP treatment was applied after homogenization, the proteins on the surface layer were present as a layer which might provide better…

▼ The bovine milk fat globule membrane (MFGM) is an important, biologically relevant membrane due to its functional and health properties. Its composition has been thoroughly studied but its structure, especially the lateral organization of its components, still remains unclear. The aim of this project was to improve the knowledge about the structure of the bovine milk fat globule and, in particular, its membrane by means of microscopic techniques and model systems. Phospholipids are the backbone of the MFGM structure. Different techniques of phospholipid extraction were carried out on buttermilk powder to determine the technique most reproducible and giving the highest recovery of sphingomyelin. Natural complex mixtures of phospholipids from raw milk, raw cream, homogenized and pasteurized milk, and buttermilk powder were recovered through total lipid extraction following the Folch method and solid-phase extraction using the Bitman method. All mixtures were analyzed using electronspray-ionization tandem mass spectrometry to determine their phospholipid profile and their fatty acid distribution, and also to reveal the effect of milk processing on the phospholipid composition. Confocal-Raman microspectroscopy was used to investigate the lipids of the milk fat globules. A comparison of the fat globule composition between two breeds of cows and between globules of different size was carried out and revealed differences in lipid content and fatty acid distribution. Confocal-Raman microspectroscopy provided information on both the lipid core and the milk fat globule membrane. Milk fat globules from raw milk, raw cream and processed milk and reconstituted buttermilk powder were stained with fluorescent probes and observed with a confocal laser scanning microscope (CLSM). Domains, which are thought to be rich in sphingomyelin and cholesterol, were observed on the surface of the native globules. These domains, also called lipid rafts, are a liquid-ordered, lo, phase coexisting with a liquid-disordered, ld, phase. Phase separation, distribution of glycoproteins and glycolipids and association of milk proteins with the MFGM were determined in all samples. Lipid microdomains, analogous to lipid rafts in cell membranes, were observed at the surface of the globules. Glycoproteins and glycolipids were heterogeneously distributed within the MFGM and located outside of the lipid microdomains. Proteins were found associated in a higher amount with the fat globule membrane after processing the milk. The temperature effect on phase separation was also assessed. Temperature induced a change in the size, shape and number of the lipid microdomains at the surface of the globules. A comparative study with the milk fat globule membrane from mares’ milk revealed similar phase coexistence at the surface of the globules. The observation in situ with non-invasive techniques provides further progress in the understanding of the lateral heterogeneities existing within the MFGM. Over the past few years, increasing attention has been… Advisors/Committee Members: Everett, David W (advisor).

▼ Fat in milk and cream is present as tiny droplets, which are each enveloped in a thin membrane, called the milk fat globule membrane (MFGM). The MFGM can easily be damaged by factors such as pumping the milk and applying other forms of agitation. MFGM damage is believed to reduce processing efficiency and compromise the quality of manufactured products. A comprehensive review of the literature showed that our understanding of changes occurring in the MFGM post secretion of the fat globule by the mammary secretory cell is still rudimentary. Furthermore, it was found that a fundamental understanding of MFGM damage in raw milk is lacking. Hence, this study sought to develop analytical techniques for studying the MFGM. Fluorescent probes were identified that associated with the MFGM (bovine, ovine, human) in one of two ways: either by embedding in the phospholipid bilayer (lipophilic probe) or by binding to carbohydrate moieties of glycosylated chains in the glycocalyx (lectin probes). The use of these probes, in combination with either conventional fluorescence microscopy or confocal laser scanning microscopy, allowed 2-D images and 3-D images of fat globules to be made. Application of water-soluble lipophilic probes and the lectin wheat germ agglutinin (WGA) directly to milk allowed the staining of the MFGM in its native environment. Variable distribution patterns of the probes in the MFGM were observed, which suggests that the MFGM of fat globules in harvested milk is structurally and chemically heterogeneous both within and among globules from the same species and between species, and even among fat globules within the milk of an individual animal. Furthermore, the binding behaviour of WGA to the MFGM of native fat globules (in bovine milk) and washed fat globules (in model systems) following heat treatment implicated β-lactoglobulin, α-lactalbumin, immunoglobulin M and/or the glycosylated proteins Periodic acid Schiff 6/7 in the disappearance of fat globule aggregation upon elevated heat treatment of milk. The results of the current study showed that the use of membrane-specific fluorescent probes, particularly in combination with confocal laser scanning microscopy, has significant potential for providing real time structural and chemical information about the MFGM in matrices such as harvested milk and milk products. In addition to the fluorescence microscopy techniques, development of other techniques was also conducted. Flow cytometry was shown to have significant potential for the quantitative determination of various properties of fat globules and their membranes. Although no suitable sample preparation technique could be developed in this study, atomic force microscopy is believed to have significant potential for studying structural and physical properties of the MFGM. Selective harvesting of individual fat globules was shown to be possible by using a micromanipulator. In future work, this technique is expected to be used in combination with fluorescence microscopy, or atomic force microscopy. The present…

Eksperiment je izveden u cilju utvrĊivanja sadrņaja masnih kiselina (FA) i njihovog meĊusobnog odnosa (SFA - zasićene masne kiseline, UFA - nezasićene masne kiseline, MUFA - mononezasićene masne kiseline i PUFA - polinezasićene masne kiseline), u mljeĉnoj masti krava koje su pasle na nizijskim, brdskim i planinskim pańnjacima, u tri fenolońke faze (rana, srednja i kasna vegetacija). Ogled je postavljen kao dvofaktorijalni (3×3), gdje je prvi faktor bio nadmorska visina pańnjaka (100 mnv, 700-800 mnv i 1600-1700 mnv) a drugi faza vegetacije. Istraņivanjem je obuhvaćeno po 20 krava sa svakog podruĉja, koje su hranjene iskljuĉivo na pańi u posmatranom periodu. Prije poĉetka ogleda sa ņivotinjama, za svaki pańnjak i svaku fazu vegetacije utvrĊen je floristiĉki i hemijski sastav biljne mase. Nizijski pańnjak je predstavljen zajednicom sa Agrostis castellana, brdski pańnjak zajednicom sa Festuca valesiaca i planinski zajednicom sa Bromus erectus. Pańnjaci se meĊusobno razlikuju kako po floristiĉkom sastavu, tako i po uĉeńću vrsta u odgovarajućim funkcionalnim grupama. Najveći broj biljnih vrsta utvrĊen je na planinskom podruĉju, ali je najpovoljniji floristiĉki sastav u smislu pripadnosti funkcionalnim grupama (Poaceae, Fabaceae) koje direktno utiĉe na hranljivu vrijednost travne mase bio na brdskom pańnjaku u sve tri faze. Ukupno uĉeńće grupe vrsta biljaka odliĉnog, vrlo dobrog i dobrog kvaliteta bilo je najveće na brdskom pańnjaku (12,90%), zatim na nizijskom (12,73%) i najmanje na planinskom (11,40%). Biljke srednjeg kvaliteta su najzastupljenije bile na brdskom pańnjaku (11,00%), na planinskom su ĉinile 10,00% i na nizijskom 6,88%. Biljke slabog kvaliteta su najzastupljenije bile na brdskom pańnjaku (23,80%), na nizijskom su ĉinile 23,53% i na planinskom 20,00%. Bezvrijedne biljke su najveće uĉeńće imale na planinskom pańnjaku (40%), na nizijskom 29,41% i najmanje na brdskom 28,50%. Grupa ńkodljivih (toksiĉnih) biljaka imala je najveće uĉeńće na nizijskom pańnjaku (27,45%), zatim na brdskom (23,80%), a najmanje na planinskom pańnjaku (18,50%)...

▼ An increasing global population, decreasing amount of arable land available for crop production in the United States, and an increased global demand for protein in the human diet encourage crop and livestock producers to seek solutions to improve the efficiency of producing large crop yields. The interaction of fungi and corn plants in the field threaten yields, decreasing the efficiency of food production and the nutritive quality of feedstuffs for ruminants. Fungicides can assist corn plants in protection from fungal infection by limiting yield losses and increasing the nutritive quality of the plant material. However, little is known about how various applications of fungicide on corn change the nutrients of individual parts of the corn plant, alter the fermentation of corn silage once ensiled, and affect the milk production when fed to dairy cattle. Therefore, the objectives of the present study were to investigate various applications of fungicide on: corn associated with the nutritive profile and growth of corn leaves, ears, stalks, and flag leaves; once ensiled, on the nutritive and fermentative profile of corn silage; and when corn silage is fed to dairy cattle on milk production, milk components, blood metabolites, and cow health. Corn from two growing seasons, 2014 and 2015, with different fungicide treatments was included in this study. Corn grown during the summer of 2014 was ensiled and fed to dairy cows, while corn grown during the summer of 2015 evaluated the plant and corn silage. In 2014, treatments were as follows: corn silage with no application of foliar fungicide (CON); corn silage received one application of pyraclostrobin and fluxapyroxad (PYR+FLUX) foliar fungicide (Priaxor®; BASF Corp.) at corn stage V5 (V5); corn silage received one application of PYR+FLUX at corn stage V5 plus another application of PYR+FLUX at corn stage V8 (V5/V8); corn silage received one application of PYR+FLUX at corn stage V5, one application of PYR+FLUX at corn stage V8, plus a third application of pyraclostrobin and metconazole (PYR+MET) foliar fungicide (Headline AMP®; BASF Corp) at corn stage R1 (V5/V8/R1). Corn was harvested at 31.2% DM and ensiled for more than 200 d before feeding. Treatments were fed to cows for 5 wk with only the last week being used for statistical inferences. Three contrast statements were used: contrast 1: CON vs. TRT compared control to the average of treatments fed corn silage sprayed with foliar fungicide (V5, V5/V8, and V5/V8/R1); contrast 2: V5 vs. V5/V8 compared the treatment fed corn silage sprayed at V5 to the treatment fed corn silage sprayed at V5 and V8; and contrast 3: V5/V8 vs. V5/V8/R1 compares the treatment fed corn silage sprayed at V5 and V8 to the treatment fed corn silage sprayed at V5, V8, and R1. No differences in DMI (19.5, 19.5, 20.8, and 20.4 kg for CON, V5, V5/V8, and V5/V8/R1, respectively) or milk yield (30.5, 31.2, 29.1, and 29.3 kg/d) were observed. However, cows in V5 when compared with cows in V5/V8 tended, to produce more 3.5% fat corrected milk (FCM;… Advisors/Committee Members: Cardoso, Felipe C (advisor), Drackley, James K (committee member), Murphy, Michael (committee member), Shike, Daniel (committee member).

▼ The objective of the first part in this study was to gain a better understanding of the protein components of the milk fat globule membrane (MFGM). In the second part, the influence of processing factors on the fat globules and the MFGM during the manufacture of whole milk powder were examined. Relationships between the state of the MFGM in whole milk powders and their reconstitutions properties were also explored. The MFGM proteins, isolated from early-, mid- and late-season fresh whole milks, were characterized using one- and two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) under reducing and non-reducing conditions. SDS-PAGE under reducing conditions showed the presence of about 40 protein bands, ranging in molecular weight from 15 to 200 kDa. The major MFGM proteins e.g., xanthan oxidase, butyrophilin, PAS 6 and PAS 7 constituted 60-70% of total MFGM proteins while 20-30% were minor proteins. Two-dimensional SDS-PAGE indicated that xanthine oxidase and butyrophilin might be complexed via intermolecular disulfide bonds in the natural MFGM. The examination of MFGM proteins heated at > 60 °C in the absence of skim milk proteins (caseins and whey proteins) showed that xanthine oxidase and butyrophilin interacted further to form very high molecular weight protein complexes, whereas PAS 6 and PAS 7 were relatively heat stable and did not form complexes. Heat treatment of fresh whole milk in the temperature range 65-95 °C caused incorporation of β-lactoglobulin (β-1g) into the MFGM. Small amounts of α- lactalbumin (α-la) and κ-casein were also observed in the MFGM material of heated milk. The amounts of β-lg and α-la that associated with the MFGM increased with an increase in temperature up to 80 °C, and then remained almost constant. The maximum values for β-lg and α-la association with the MFGM were ~1.0 mg/g fat and ~0.2 mg/g fat, respectively. Association of β-lg and α-la with the MFGM was described by a first-order reaction (65-85 °C for β-lg and 70-80 °C for α-la) in the low temperature range and by a second-order reaction in the high temperature range (85-95 °C for β-lg and 80-95 °C for α-la). Arrhenius plots showed an abrupt change in temperature dependence of the rate constants at 85 °C for β-lg and 80 °C for α-la. Of the major original MFGM proteins, xanthine oxidase and butyrophilin were not affected by the heat treatment of whole milk, whereas PAS 6 and PAS 7 decreased during heating. Interestingly, this behaviour is in contrast to that shown by these proteins in systems containing no skim milk proteins. The changes in fat globule size and MFGM proteins during the manufacture of whole milk powder were determined using light scattering, SDS-PAGE, confocal laser scanning microscopy (CLSM) and transmission electron microscopy (TEM). Heat treatment of whole milk by direct stream injection (DSI) prior to evaporation caused a decrease in the fat globule size and an increase in the MFGM protein, through the association of caseins and whey proteins with the MFGM material.…

▼ Enantiomeric and racemic triacylglycerols (TGs) representative of the major structural classes in milkfat were synthesised and their polymorphism was characterised by differential scanning calorimetry (DSC) and infrared (IR) spectroscopy. With butyric (B), oleic (O), palmitic (P) and stearic (S) acids as starting materials, 22 racemic TGs were prepared. The main TG classes were: 1) palmitoyl-stearoyl TGs (e.g. PSS), 2) 1-butyryl TGs (BPS), 3) 1-oleoyl TGs (OPS), 4) 2-oleoyl TGs (POS), 5) 1-butyryl-2-oleoyl TGs (BOS) and 6) 1,2-dioleoyl TGs (OOS). Three TGs containing elaidic acid (E) were also synthesised (BES, ESS and SES). In addition, enantiomers of three of the racemic TGs belonging to the 1-butyryl and 1-oleoyl classes were prepared (sn-SSB, -SSO and -PPO). The polymorphic forms of each TG were classified as α, β' or β by comparison of their the spectra with the spectra of the polymorphic forms of monoacid TGs. Solvent crystallised forms were also characterised by X-ray powder diffraction. Melting points of all polymorphs and heats of fusion of the least stable (α) and most stable forms were determined by DSC. However, the determination of the polymorphic assignment and heat of fusion of the intermediate forms was often uncertain because of the difficulty in obtaining a pure phase. The principal findings were:- 1) Corresponding enantiomeric and racemic TGs exhibited similar polymorphic behaviour except that the α forms of the enantiomers transformed more rapidly than those of their racemates. 2) For TGs in which one fatty acid was very different from the other two (e.g. BSS, OOS), the position of the unusual acid determined the chain packing of the stable form. If the acid was in a primary position, the TG was β'-stable (e.g. BSS, OSS, OOS), while if it was in the secondary position, the TG was β-stable (e.g. SOS, SBS). 3) There were close parallels between the stable forms of corresponding butyryl and oleoyl TGs (e.g. BSS, OSS; SBS, SOS; BOS, OOS), although in other respects their polymorphism had little in common. The stable forms of BSP and OSP showed anomalous thermal, diffraction and spectral data compared with the remaining 1-butyryl and 1-oleoyl TGs. 4) The results obtained for the 1-oleoyl, 2-oleoyl and 1,2-dioleoyl TGs were in general agreement with earlier reports, although some differences were noted in the transformation of OSP, OPS, SOS and POP. Furthermore, previously undetected transitions were observed for all the oleoyl TGs, although these were minor. A new polymorph of OPP was also characterised. With the exception of POS, all monooleoyl TGs showed anomalous crystallisation behaviour. 5) The results for the polymorphism of the palmitoyl-stearoyl and elaidoyl-stearoyl TGs were also in accord with previous reports. The presence of a β'2 form was confirmed for all TGs except SPS and PSP. The heats of fusion of the β forms of SPS and PSP were comparable with those of their unsymmetrical counterparts, PSS and PPS, but the heats of fusion of their stable β' forms were much higher than those of β'…

▼ The milk fat globule membrane (MFGM) plays an essential role in emulsifying milk fat. In recent decades, the behavior of MFGM polar lipids has been studied using Langmuir trough model systems, were the surface tension of lipid monolayers spread on the surface of a aqueous solution is analyzed as the surface is compressed or expanded. The problem with most Langmuir trough experiments reported in the literature that study MFGM lipid behavior is that they spread MFGM lipids on solutions that are not fully representative of milk. Pure milk naturally contains protein and lipid surfactants, which makes studying the behavior of isolated lipid monolayers spread on pure milk difficult. In this thesis, a process to produce non-surface-active (NSA) solutions from bovine skim milk and dairy-based beverages that have insignificant amounts of surfactants is described. The resulting NSA solutions from the process described here can be used to improve Langmuir trough experiments on MFGM lipids. The process to produce NSA solutions involves two steps. The first step is ultrafiltration of milk through an ultrafiltration membrane with a molecular weight cut-off of at least 10 kDa. The second step is washing the permeate obtained from ultrafiltration 4 times with water-immiscible solvents at a 10:1 permeate to solvent (v/v) ratio. Collected permeate is washed once with hexane, once with chloroform, and then twice with hexane before being filtered through activated carbon. Solvent washing removes proteins in the permeate by forming protein stabilized permeate-in-solvent emulsions that can be separated from the permeate in a separatory funnel. NSA solutions produced from skim milk had a significantly higher surface tension than pure skim milk, resulting from the loss of surfactants. There was no significant difference in the surface tension of the resulting NSA solutions when their surface was compressed, indicating a lack of adsorbed surfactants at their surface. Percent total solids were lower in the NSA solutions compared to bovine skim milk due to the removal of proteins, but the measured pH, conductivity, hardness, and alkalinity of the NSA skim milk permeates was not significantly different to that of pure skim milk. The process of producing NSA solutions from milk was also carried out for 3 different dairy-based beverages to show that the process is not limited to just milk. Lastly, the lift-off point, which is the mean molecular area at which the surface pressure significantly rises above 0 mN/m, was compared for milk ganglioside GM3 monolayers spread on ultrapure water to those spread on NSA bovine skim milk permeate. The difference in lift-off points for milk GM3 monolayers spread on the different subphases was found to be significantly greater than zero for each milk GM3 sample analyzed. In essence, the procedure described in this thesis to produce NSA solutions from milk and dairy-based beverages can improve Langmuir trough experiments studying interfacial MFGM lipid behavior by making the experiments resemble milk more… Advisors/Committee Members: Jimenez-Flores, Rafael (Advisor).

▼ With the increasing environmental concern for N excretion in the environment, the nutrition of dairy cows meets new challenges to maintain milk production while decreasing dietary protein. Various strategies to improve efficiency of N utilization in milk production have been developed. Decreasing protozoal abundance and the corresponding improvement of microbial protein efficiency could improve this efficiency of dietary protein utilization. The feeding of fat usually decreases the abundance of protozoa but can have detrimental effect on ruminal fermentation and milk fat production, thus needing further study to ascertain the potential benefits relative to potential detriments. In a first study, the effects of the availability of dietary fatty acids from cottonseed oil on ruminal metabolism and milk fat production were investigated. In our study, feeding a mix of pelleted and delinted cottonseeds appeared to modify ruminal fatty acid metabolic processes, decreasing the risk of milk fat depression and tending to increase dry matter intake and milk production over time compared with conventional or pelleted cottonseeds. In a second study, the effects of feeding Rumensin (R) in combination with animal vegetable (AV) fat or coconut oil were fed to six rumen-cannulated dairy cows. Using omasal collection, I measured microbial protein efficiency and nutrient digestibility. By feeding R to control the extent of amino acid deamination and combined with fat to control protozoal abundance, the efficiency of microbial protein synthesis might be improved in dairy cows. Animal vegetable fat can be biohydrogenated in the rumen and decrease its effectiveness, but diets supplemented with coconut oil (CO; rich in medium chain FA) are more consistent in inhibiting protozoa. Total protozoal abundance was decreased by CO supplementation for all genera expect for Epidinium, which maintained its numbers but was decreased by AV+R. The low acetate to propionate ratio for CO was associated with a decreased ruminal NDF digestibility. There was no effect of diet on efficiency of microbial protein synthesis. DMI was 5 kg/d lower with CO. Milk production was lower when cows were fed CO than AV and when diets contained R. Milk fat depression (MFD) occurred with AV+R and CO. The decrease in protozoal abundance was not associated with an increase in microbial protein efficiency. The detrimental effect of CO on DMI affected the energy available for milk synthesisOmasal flows of FA were characterized by an increased percentage of trans 18:1 for AV and CO diets, a higher percentage of 12:0 and 14:0 for CO, and higher cis 18:1 for AV. Milk FA composition reflected the changes observed for omasal FA digesta flow. The de novo FA synthesis in the mammary gland was inhibited with R and F supplementation. Higher trans 18:1 FA in milk fat was also observed for AV and CO. The feeding of CO did not prevent MFD, and no interactions between R and S were detected. The feeding of CO did compromise ruminal biohydrogenation, with accumulation of trans 18:1 in the… Advisors/Committee Members: Firkins, Jeffrey (Committee Chair).

Tyrimo problema: Pienininkystei Lietuvoje plėtoti sąlygos yra palankios, pienas žemės ūkio produkcijos struktūroje užima beveik ketvirtadalį, o pieno produktų eksportas sudaro apie penktadalį šalies žemės ūkio ir maisto produktų eksporto. Lietuvoje karvių produktyvumas artimas Lenkijos ir Latvijos karvių produktyvumui, tačiau nuo kitų Europos Sąjungos šalių karvių produktyvumas atsilieka 15 – 20 proc. Todėl norint konkuruoti pasaulinėse rinkose būtina atrasti patikimų būdų gerinti karvių pieno kokybės rodiklius, taip pat didinti primilžį. Darbo tikslas: ištirti melsvadumblio Spirulina Platensis įtaką pieno sudėties rodikliams. Šiam tikslui įgyvendinti keliami tokie darbo uždaviniai: 1. Ištirti Spirulina Platensis papildo vartojimo įtaką primilžiui. 2. Ištirti Spirulina Platensis papildo vartojimo įtaką pieno sudėties rodikliams. 3. Ištirti Spirulina Platensis papildo vartojimo įtaką somatinių ląstelių skaičiui piene. Atlikę bandymą 8-iuose Lietuvos rajonų ūkiuose nustatėme, kad karvių šėrime panaudojus Spirulina Platensis papildą, iš bandomosios grupės karvių per parą primelžta vidutiniškai 2,44 kg arba 14,2 proc., pieno daugiau, nei iš kontrolinės grupės karvių (p<0,05). Vartojant Spirulina Platensis papildą bandomosios karvių grupės pieno riebumas buvo nustatytas vidutiniškai 0,27 proc., mažesnis, nei kontrolinės karvių grupės (p<0,05), tačiau iš bandomosios karvių grupės per parą gaunama 0,07 kg daugiau pieno riebalų. Pieno baltymingumas bandomosios karvių grupės piene... [toliau žr. visą tekstą]

Research problem: The conditions of the dairy development are favorable in Lithuania. The milk production takes up nearly a quarter of the whole agriculture production and the export of dairy products is about one-fifth of the country agricultural and food export. Lithuanian cow productivity is close to the Polish and Latvian cow productivity, but is about 15 – 20 percent lower than in other European Union countries. Therefore, in order to compete in global markets, it is necessary to find ways to improve the quality of milk, as well as to increase the milk yield. Research purpose: To investigate the influence of the blue-green algae (Spirulina platensis) on the milk composition parameters. For this purpose there are the following tasks: 1. Investigationoftheinfluenceof Spirulina platensis onthemilkingyield. 2. Investigationoftheinfluenceof Spirulina platensis onthemilkcompositionparameters. 3. Investigationoftheinfluenceof Spirulina platensis ontheamountofsomaticcellsinmilk. After tests in eight Lithuanian farms, it was found that the use of Spirulina platensis additives in cow feeding increases the average of milk yield of about 2.44 kg or 14.2 percent in compare with the control group (p<0,05). Although the additives of Spirulina platensis reduces the fatness of cow milk of about 0.27 percent, but absolute amount of the milk fat increases of about 0.07 kg pro day. In the similar way, the milk protein in the test group was lower of about 0.14% than in the control groups of... [to full text]

Brzi razvoj molekularne genetike tokom posledenje tri decenije omogućio je direktnu analizu genoma životinja, proučavanje strukture i funkcije gena, pa samim tim pomogao boljem razumevanju delovanja nasledne osnove. Molekularno-genetičke metode omogućile su uvid u nekodirajuće delove genoma, koje kod sisara čine više od 90%. DNK (dezoksiribonukleinska kiselina) zapisa. U slučаjevimа gde se prаte osobine koje su generаlno sа niskim heritibilitetom, kаo što je slučаj sа otpornošću nа mаstitis, MAS (mаrker аsistirаnа selekcijа) ili genomskа selekcijа pokаzаle su bolji rezultаt u odnosu nа konvencionаlni metod selekcije. Primаrni cilj u ispitivаnju kаndidаt-genа povezаnih sа pojаvljivаnjem mаstitisа je identifikаcijа genа koji su uključeni u proces imunog odgovorа mlečne žlezde. Laktoferin gen (LTF) se u većem broju istraživanja pominje kao validni molekularni marker u praćenju procesa otpornosti mlečne žlezde prema infekciji. Cilj ovog rada bio je ispitivanje polimorfizma gena za LTF i njegov uticaj na zdravstveni status mlečne žlezde i proizvodne karakteristike krava holštajnfrizijske rase u Srbiji. Ogled je obuhvatao 100 krava različite laktacione starosti (1.-4. laktacija) na farmi blizu Beograda. Životinje su bile ravnomerno raspoređene u grupama po laktacionoj starosti (χ2=0,578; p=0,902). Posle ekstrakcije DNK iz krvi amplifikovan je fragment gena za laktoferin na intronu 6 metodom PCR (polymerase chain reactionreakcija lančane polimeraze). Pomoću specifičnih prajmera, identifikovana su dva genotipa AA i AB od moguća tri, (BB nije identifikovan) metodom PCR-RFLP (Restriction Fragment Lenght Polymorphism-polimorfizam u dužini restrikcionih fragmenata). U cilju ispitivanja zdravstvenog statusa mlečne žlezde, kvalitativnog sastava i ukupne proizvodnje mleka, svakog meseca kroz period standardne laktacije od 305 dana, su uzimani uzorci mleka. Broj somatskih ćelija (SCC) određivan je mikroskopski a koncentracija proteina i mlečne masti utvrđivana je spektrofotometrijski (aparat Milkoscan). U zajedničkom uzorku od 90 krava, konstatovana je statistički vrlo značajno veća (χ2=40,894; p<0,001) zastupljenost genotipa AA ( 74 ili 82,22%) u odnosu na zastupljenost genotipa AB ( 16 ili17,78%). Prema Hardy-Weinberg jednačini odnos genotipova AA, AB i BB se nalazi u ravnoteži (p=0,3547). Distribucija A alela u posmatranoj populaciji bila je 91,11% a B alela 8,89%. Ovako visok broj homozigota ukazuje na smanjeni protok gena u populaciji i veći stepen genetske konzervisanosti zapata. Poizvodne karakteristike praćenih genotipova nisu se statistički razlikovale...

▼ Milk fat is a versatile ingredient because of its nutritional value, functionality, and flavor. During processing and storage, milk fat may undergo oxidation resulting in many undesirable changes such as unpleasant flavor and aroma, and formation of toxic compounds. A common practice to prevent the oxidation of milk fat is by the addition of antioxidants. It is worth to mention that little is known on the effect of antioxidants on the oxidation kinetics. In this work, the effect of selected antioxidants on the oxidation kinetics of anhydrous milk fat (AMF) under non-isothermal conditions was investigated. AMF with an addition of either butylated hydroxytoluene (BHT), α-Tocopherol (α-Toc), or β-carotene (β-Car) at four different concentrations (0.02, 0.07, 0.2, and 0.4%) were oxidized using differential scanning calorimetry (DSC) at different constant heating rates (3, 6, 9, and 12°C min-1) in a temperature range of 100-400°C. DSC spectra were analyzed according to the Kissinger-Akahira-Sunose (KAS) method, from which the kinetic triplet was obtained (pre-exponential factor (A), apparent activation energy (Ea), and reaction model (𝑓(∝)). In general, the concentration of antioxidant increased the onset temperature of oxidation (Ton) when comparing to the Ton of AMF without antioxidant. The Ea values were 82.73 ± 5.51, 93.14 ± 6.24, 68.06 ± 3.52, and 58.51 ± 7.51 kJ mol-1 for AMF, BHT, β-Car, and α-Toc, respectively. Remarkably, the addition of 0.2% of α-Toc inhibited the oxidation reaction by 9-fold, judging the constant rate. The obtained kinetic parameters were interpreted in term of oxidation mechanism. The oxidation of milk fat was best described by the Avrami-Erofeev model. The obtained kinetic triplet (Ao, Eo, and 𝑓(∝)) was used to systematically evaluate the role antioxidants. The addition of antioxidants significantly delayed the oxidation, being more effective α-Toc followed by β-Car and BHT. The outcomes of this study may enable off-line simulation and development of a databank. Advisors/Committee Members: ergio Martinez Monteagudo.

▼ Three studies were conducted in order to identify strategies to avoid milk fat depression in dairy cows when diets are supplemented with rich oils PUFA. Literature research in the first study showed that the most commonly reported intake recommendations of CLA for human are 0.8 g/d (from 0.6 to 3.0 g/d), although all recommendations have been extrapolated from animal models and the few human studies reported contradictory results. We selected published papers (n = 69) where dairy cows were fed different fats and the milk fat content and FA profile were reported. Considering the changes in CLA and milk fat content, supplementation with fish oils together with vegetable oils would be the best strategy (395 mg of cis-9, trans-11 CLA/l vs. 188 mg of cis-9, trans-11 CLA/l; increase of 2.1 times). The estimated current average human consumption in Europe, US and Canada is 0.21 g/d. If we assume an increase content of 2.1 times in CLA in milk, average human consumption would increase from 0.21 to 0.46 g/day. Although there is sufficient data on feeding strategies to increase CLA content in milk, human requirements have not been well established and, based on current recommendations, they are unattainable even if all milk and milk products were consumed as CLA enriched products. In the second study, two experiments (bath culture fermentation and continous culture fermenters) were conducted to determine the effects of lipases and essential oils on rumen fermentation and apparent biohydrogenation of linoleic and linolenic acids. Treatments were control, lipase 1 and 2, a lipase inhibitor, PTSO; Eugenol and CIN (experiment 1), and control, lipase 1, PTSO and CIN (experiment 2) at two pH levels (6.4 and 5.6). In experiment 1, Lipase 1 increased the apparent biohydrogenation of LNA and reduced the efficiency of intermediary steps of biohydrogenation of LA and LNA but these results were not observed in experiment 2. The PTSO inhibited the apparent biohydrogenation of LA and LNA and decreased total VFA concentrations in the two experiments. The third study was based in the fact of feeding linseed to dairy cows results in milk fat depression (MFD), but there is a wide range of sensitivity among cows. The objectives of this study were to compare the mRNA expression of transcripts expressed in milk somatic cells in cows resistant or sensitive to MFD, and to identify metabolic pathways and transcription factors affected by MFD in resistant or sensitive cows. Four cows were selected from a dairy farm after a switch from a control diet to a linseed-rich diet. Among them, two cows (R-MFD) were resistant to MFD having high milk fat content in both control (4.06%) and linseed-rich diet (3.90%); and two cows (S-MFD) were sensitive to MFD decreasing milk fat content after the change into the LIN diet (3.87 to 2.52 %). Differential expression analysis between S-MFD and R-MFD cows allowed to detect a large number of differentially expressed genes in both diets, CTR (n = 1,316) and LIN (n = 1,888). Pathway and key gene regulator analysis also… Advisors/Committee Members: [email protected] (authoremail), true (authoremailshow), Calsamiglia Blancafort, Sergio (director), true (authorsendemail).

Pieno produktai, prieš patekdami į prekybą, turi atitikti svarbiausius maisto produktų kokybės reikalavimus. Kaip kokybiškos ir saugios pieno produktų gamybos rodikliai yra tikrinami bendras mikroorganizmų skaičius, koliforminių bakterijų, enteropatogeninių mikroorganizmų, listerijų, vaškinių bakterijų, pūlingų infekcijų sukėlėjai, pelėsinių grybų ir mielių kiekiai piene (Staniškienė ir kt., 2007). Pieno supirkimo taisyklėse numatyta nemažai rodiklių, kurie apsprendžia pieno kokybę. Tai bendra bakterinė tarša, somatinių ląstelių kiekis, inhibitorinių medžiagų nebuvimas ir užšalimo temperatūros rodikliai. Visi šie rodikliai tarpusavyje susiję ir vienam jų pakitus, priežastį galima išaiškinti, analizuojant kitus. Pavyzdžiui, padidėjus somatinių ląstelių kiekiui, piene galima aptikti inhibitorinių medžiagų, kas rodo, kad sveikų karvių pienas sumaišytas su sergančių. Kiekvieno rodiklio nuokrypiai įtakoja ir pieno kokybę. Šiuolaikinės technologijos leidžia iš pieno pašalinti dalį somatinių ląstelių, sumažinti bakterijų kiekį, bet išnaikinti antibakterines medžiagas, vadinamas inhibitoriais, nepavyksta (Greičiuvienė, 2009). Stebėjimai parodė, kad karvių, apsiveršiavusių rudenį bei žiemos pradžioje, pienas būna riebesnis, nes vasarą ir rudenį yra pakankamai geros kokybės pašarų, vertingų maisto medžiagų ir ląstelienos, iš kurios ir sintetinamos pirminės pieno riebalų medžiagos. Pavasarį pašarai būna blogesni. Anksti išginus karves į ganyklą, žolėje yra mažai ląstelienos. Darbo... [toliau žr. visą tekstą]

The aim of this project was to apply statistical process control (SPC) and measure the variation of fat content in milk in order to improve the standardization, so that the fat content does not change more than 0.03 percentage units from target. Recommendations of how to adjust the standardization should also be developed. The standardization takes place together with pasteurization in one of the three pasteurizers. Thereafter, the milk goes to a common product tank with all the pasteurizers. Samples from the three pasteurizers and the product tank were collected and analyzed on MilkoScan FT2 and the fat content was plotted into Shewhart and cumulative sum (CUSUM) charts. Sampling on the pasteurizers from startup showed that samples should be taken after about 20 minutes, because then the variation is in general smaller. The data from the product tank showed a smaller variation than the pasteurizers. Because the milk from all the pasteurizers is transported into one product tank, it is impossible to know which pasteurizer that is out of control and need to be adjusted. Therefore, the conclusion is that samples should be taken after the pasteurizer and plotted into Shewhart and CUSUM charts. Action limits were achieved from the Shewhart and CUSUM charts, respectively. These are the limits that should be used to determine when adjustments of the pasteurizers are needed, and not the brand limits that are considerably wider. If the measurements fall outside the second limit in the Shewhart chart (three times the standard deviation) or outside the limits (H) in the CUSUM chart, the standardization before the pasteurizer in question should be considered. It is not known if using SPC will improve the fat content to be within 0.03 percent units from target, because the recommendation has not been applied in the process yet, but it going to be that soon.

Syftet med detta arbete var att implementera statistisk processtyrning och mäta variationen i mjölkens fetthalt för att kunna förbättra standardiseringen. Detta skulle medföra att fetthalten inte förändras mer än 0,03 procentenheter från målet. Rekommendationer om hur standardiseringen bör justeras av fetthalten i mjölk ska också utvecklas. Standardiseringen sker tillsammans med pastöriseringen i en av de tre pastörerna. Därefter går mjölken till en gemensam produkttank för pastörerna. Prover från de tre pastörerna samt produkttank samlades in om analyserades på MilkoScan FT2 och fetthalten plottades in i Shewhart och Kumulativsumma (CUSUM) diagram. Provtagning från produktstart på pastörerna visade att prover skulle tas efter 20 minuter, eftersom variationerna då är mindre. Data från produkttank visade en lägre variation än hos de tre pastörerna. Eftersom mjölken från pastörerna transporteras till en produkttank är det omöjligt att veta vilken av de tre pastörerna som är utom kontroll och bör justeras. Därför är slutsatsen att proverna ska tas efter pastörerna och plottas in i Shewhart och CUSUM diagram. Åtgärdsgränser togs fram för både Shewhart och CUSUM…
