▼ Animal welfare is very important these days. Consumers are more aware of what they eat and demand for transparency of production of animal production. Farmers also want their animals to live a good life. It is well known that poor health and poor housing cause stress to cows and stress will lower the milk production. So the current idea is that good cow comfort will result in better milk production. In this study, the cow comfort of 36 farms was scored using the Cow Comfort Scoring System and the total score and all chapters and items of this system were compared with milk production parameters. The parameters used are the Fat Corrected Milk production (FCM), milk fat percentage and milk protein percentage. The total score of the system did not correlate at the 0.05 level with the FCM (P = 0.096 and R = 0.295). But since the data used for the biggest chapter of the scoring system, animal health and feeding, was not very reliable, the score for this chapter was excluded and the trend became more clear and the correlation larger; the P of FCM goes to 0.073. The correlation between the total scoring and the milk fat percentage also became larger this way; the P went from 0.568 to 0.162. Comparison of the FCM with the cow comfort chapter and items showed several significances. FCM was significant with the chapter water (P = 0.012; R = 0.431), the item number of water places (P = 0.015; R = 0.420) and the item contamination of the feeding (P = 0.008; R = 0.456). There also was a correlation between FCM and the item claws (P = 0.001; R = 0.536). Furthermore, there was a negative correlation between FCM and the items period of light (P = 0.026; R = -0.388) and period of darkness (P = 0.006; R = -0.470). The milk fat percentage was negatively correlated to the chapter light (P = 0.013; R = -0.427) and the item sufficient light (P = 0.045; R = -0.346) and the milk protein percentage was negatively correlated to item claws (P = 0.023; R = -0.454). The hypothesis of this study was that the milk production parameters would be correlated to the total score of the Cow Comfort Scoring System and possibly also to the different chapters and items of the system. But only a few significant correlations were observed and some of the correlations are not clear yet. This is because during this study, only 36 farms could be scored. To draw proper conclusions, a larger number of farms is necessary. Advisors/Committee Members: Eerdenburg, F.J.C.M. van.

▼ Sodium discharge from dairies in California has been identified as an important contributor to soil and water pollution. The Waste Discharge Requirements General Order For Existing Milk Cow Dairies (2007) aims to minimize the amount of fixed solids, including Na, that are discharged from dairies, aiming to maximise the useable lifespan of water resources. As sodium bicarbonate (SB) contains 270 g/kg Na, SB supplementation can substantially increase Na discharge from dairies. The aim of this study was to determine the effects of SB and a potentially alternative buffer that does not contribute to Na discharge and related negative impacts on soil and water quality, (i.e., calcium magnesium carbonate (CMC)), on the performance of high producing California dairy cows. This could help establish if CMC could substitute for SB while maintaining potential benefits of SB. It is well known that SB is a rumen buffer, but research indicates that its benefits are limited mainly to corn silage-based diets. Californian dairies use a wide range of forages, and tend not to base their diets solely or mainly on corn silage. Therefore, typical Californian lactation diets do not always conform to those reported in research publications involving SB. In addition, research parameters such as milk yield, DM intake and dietary ADF often differ substantially between reported studies and conditions present on commercial California dairies, and results are therefore not always practically applicable. Apart from its rumen buffering capacity, SB also has an influence on dietary cation anion difference (DCAD), and can therefore elicit a response via a change in blood acid base balance of cows. The experiment was a Latin square design with 3 treatments (i.e., control (C), SB and CMC), 3 pens of ~310 early lactation cows each, and 3 periods of 28 d. Sodium bicarbonate supplemented cows had elevated milk fat proportion, but a reduced milk yield, resulting in similar milk fat yield between SB supplemented and C cows. Based on a tendency for elevated faecal and in vitro rumen fluid pH, SB had a buffering effect on the gastrointestinal tract GIT, most likely in the rumen. However, it is likely that the difference in DCAD between the C and SB diets played a role in affecting milk yield and milk fat proportion, and a high intake of Na may have been the cause for a reduction in milk yield resulting in passive increase in milk fat proportion. There were no differences between C and CMC treatments, except for an elevated faecal pH of CMC cows. As CMC is not generally soluble at normal rumen pH, buffering likely occurred in the abomasum and small and large intestines. However, a lack of difference in productivity indicates that the buffering effect on the hindgut was not physiologically required. While there were no productive benefits of SB use, it likely substantially increased Na discharge, resulting in an increase in soil and water sodicity and the associated deterioration in soil and water quality.

[Truncated abstract] There have been limited studies that investigated the relationships between variations in milk composition and milk production despite reports of wide variations in both composition and production between mothers with preterm infants. To this end I investigated these relationships during the first two weeks postpartum and from days 15 to 57 postpartum (established lactation). Samples for Chapters 2‐4 were obtained from a study conducted by Stanford University whereby milk samples were collected together with the milk production data from mothers with preterm infants from days one to 57 postpartum. There was a significant positive relationship between variations in concentration of lactose and variations in milk production during the first two weeks postpartum [p<0.05] whereby increased concentration of lactose was accompanied by an increased milk production. This observation was consistent with the reported osmotic effect of lactose. With protein even though there was a significant negative relationship between variations in concentration of protein and variations in milk production [p<0.05] this relationship was not significant when days postpartum was taken into account. From days 15 to 57 postpartum there was no significant relationship observed between variations in concentration of lactose and milk production either in a univariate relationship or taking days postpartum into account. While the reasons were not clear it may be that by this time the osmotic potential of lactose was saturated out. Similarly there was no significant relationship observed between variations in concentration of protein and milk production during this period.

Other milk components analysed during the first two weeks postpartum included citrate and fatty acids. There was a significant positive relationship between variations in concentration of citrate and variations in milk production [p<0.05]. This was thought to be due to the close association between the synthesis of lactose and citrate. Similarly there was also a significant positive relationship observed between variations in propostion of de novo synthesised fatty acids (capric, lauric, and myristic acid ) and variations in milk production [p<0.05]. Similarly this was thought to be due to the close association between the synthesis of these fatty acids and citrate. The synthesis of these macronutrients were observed to be significantly related to milk production and that the wide variations in both milk composition and production between mothers are thought to be associated with differences in maturity of the mammary secretory epithelial cells (lactocytes). Differences in the levels of premature birth and also levels of prolactin (required for establishment of successful initiation of lactation) are thought to cause variations in maturation between these lactocytes. This has a significant effect on the synthetic capacity of the lactocytes and thus could account for the wide variations in milk composition and production observed between…

▼ Malnutrition is a serious problem in 1-5 years old children of Ethiopia and livestock products have a contribution in solving malnutrition. This study was conducted in and around Bahir Dar with the objectives of investigating the contribution of cow ownership and milk production to child milk consumption; assessing constraints in cow milk production and child milk consumption; and assessing the quality of cow milk consumed by children at household level. Cross- sectional study design was employed. A total of 300 households were individually interviewed. The results indicated a positive relationship between dairy cow ownership and child milk consumption. A child in a household with dairy cow consumes 464.9 ml of milk while in a household without dairy cow consumes 457.5ml of milk. Among households with dairy cow and without dairy cow larger volume of milk offer was observed in the periurban (512.8ml) and urban areas (465.7ml), respectively as compared with the rest. In terms of child milk feeding practice, higher practice of child milk feeding was obtained in the urban households with 39% and without 60.7% dairy cow. The major constraint of child milk consumption across households with and without dairy cows was selling of milk for income generation and lack of knowledge; and shortage of money and cultural issues, respectively. Coliform and standard plate counts in the urban, peri-urban and rural areas were 4.7X103 and 104, 3.1X104 and4.6X104, 2.2X105 and 5X105, respectively. The overall result of adulteration and acidity were 26.11 and 0.21, in CFU respectively. The general hygienic practice followed by households with dairy cows in the area is poor. Feed shortage is the biggest problem for all the study sites, whereas shortage of land is a priority problem for urban and peri-urban dairy owners and lack of improved breeds is a priority problem for the rural farmers. Reduction of milk production and quality affects child milk consumption. Therefore, further research works to address constraints and to improve child milk consumption are imperative.

Com o objetivo de determinar a influência dos sistemas de produção e de alimentação sobre as características do leite, dados coletados de produtores de leite do sul do Brasil e de experimentos sobre níveis de restrição alimentar e de atendimento das exigências energéticas de vacas em lactação foram submetidos à análise de fatores principais, de correlação e médias canônicas, agrupamento e comparação de médias dos grupos. Os atributos estudados comuns em todos os sistemas foram produção leiteira diária, componentes lácteos, estabilidade do leite, peso corporal e escore de condição corporal. Na análise dos sistemas de produção, três grupos de produtores foram formados pela análise de agrupamento, com características de sistemas especializados, semi-especializados e não especializados em ambas as regiões avaliadas. Grupos de produtores especializados produziam leite em conformidade com as especificações da Instrução Normativa Nº 62. Enquanto que para os produtores da região sul do Rio Grande do Sul, as estratégias de alimentação foram determinantes para distinção entre os grupos de produtores, no extremo oeste de Santa Catarina a estrutura das propriedades foi mais determinante. Níveis de restrição severos (40 e 50%) alteraram significativamente a produção leiteira diária, os teores de proteína e lactose e a estabilidade do leite. O atendimento das exigências energéticas para vacas em lactação possui uma relação direta com a produção diária de leite, com o teor da lactose e com a estabilidade do leite. A produção leiteira, os componentes lácteos e a estabilidade do leite diferenciam-se entre os sistemas de produção e alimentação.

Aiming to determine the influence of production and feeding systems on milk characteristics, data collected from dairy producers in southern Brazil and experiments on levels of feed restriction and attendance of the energy requirements of lactating cows were subjected to principal factor, correlation and means canonical, cluster analysis and comparison of means between groups. The variables common to all systems were daily milk production, milk components contents, ethanol stability, body weight and body condition score. In the analysis of production systems, three producers groups were formed by cluster analysis, with characteristics of specialized, semi-specialized and unspecialized systems in both regions evaluated. Groups of specialized dairy farmers produced milk in accordance with Normative Instruction Nº 62. While for the producers in southern Rio Grande do Sul, the feeding strategies were crucial to distinguish groups, at the far west of Santa Catarina structure of the properties was more important. Severe feed restriction levels (40 and 50%) altered significantly the daily milk yield, protein and lactose contents and ethanol stability. Attendance of the energy requirements for lactating cows showed a direct relationship with the daily milk production, content of lactose and milk stability. Milk production, milk components and milk stability are different between production and…

▼ Maternal milk production influences calf weaning weight which is the major driver for economic return in a cow-calf operation. The objective of this study was to use measures of calf milk intake to estimate milk production of Angus (AA; n=43), Angus×Friesian (AF; n=32), Angus×Jersey (AJ; n=40) and Angus×Kiwi-Cross (AK; n=21) cows, and to determine how milk yield was related to calf growth rate (n=64) from birth to one year of age. Milk production was estimated by the weigh-suckle-weigh (WSW) technique at an average 32, 49, 80, 120 and 160 days (D) post-partum. Third-order Legendre polynomials were fitted to milk data using random regression to estimate the lactation curve for each cow. Live weight of all steers was recorded at birth and thereafter accompanying every WSW measurement. Postweaning live weight was recorded at an average D240, D330 and D350 of age. Growth curves for each steer were estimated by fitting third-order Legendre polynomials to live weight data using random regression. The average total milk production from D32 to D160 was 1337 ± 22 kg for AF cows, 1245 ± 20 kg for AJ cows, 1301 ± 32 kg for AK cows and 1017 ± 20 kg for Angus cows. The AF, AJ and AK cows produced more (P<0.05) milk from D32 to D160 than the AA cows. The AF cows produced more (P<0.05) milk than AJ cows, with AK cows being intermediate and not differing (P>0.05) from either AF or AJ cows. Crossbred cows produced more milk (P<0.05) at all stages of lactation when compared with straightbred AA cows. In the present study, as the proportion of Friesian or Jersey in the crossbreds increased from 0 to 50%, an extra 325 kg and 240 kg of milk, respectively, was expected compared to the AA cows. Total energy intake from milk was higher (P<0.05) for the AF-, AJ- and AK-reared steers compared to those reared by AA dams. This resulted in higher liveweight gains so that steers reared by crossbred cows were heavier (P<0.05) from D60 to D270 than those reared by AA cows. Results also revealed that the higher live weight at D60 in AJ-reared steers compared to AA-reared steers was due to differences in milk consumption from D32 to D60. The higher live weight of AF- and AK-reared steers at D60 compared to AA-reared steers was attributed to a maternal effect on steer size; however, from D90 until weaning at D160, any differences in live weight were due to differences in milk consumption. Estimation of the theoretical pasture consumption revealed that AA- reared steers compensated for the lower milk intake by eating more grass, however, this was not enough to support high daily gains during the pre-weaning period. The differences in live weight seen at weaning between steers were maintained post-weaning until D270 and were attributed to differences in milk consumption during the pre-weaning period. Under nonlimiting nutrient availability, AF, AJ and AK cows were able to pr

▼ The aim of this thesis is to enquire into genetic approaches for improving milk yield from dairy cattle in order to overcome the milk shortage in Bangladesh. Survey work on the dairy industry was carried out to reveal its current status. The collected data of different genotypes (Pabna cattle, Australian-Friesian-Sahiwal Pabna, Holstein Pabna, Jersey Pabna, and Sahiwal Pabna) from 1999 to 2001, and in two seasons, were used to predict model parameters, fit-statistics and total lactation yields, by fitting ten lactation curve models. Best fitting model(s) were chosen on the basis of fit-statistics. The input parameters from best fiting model(s) were used for: developing a deterministic model; estimating the profitability of individual cows; estimating whole farm profitability; and for developing a profit function to estimate the economic values of traits in breeding objectives. The individual cow performances for different traits were stochastically simulated in respect of additive genetic, permanent and temporary error, herd and age effects, and mendelian sampling under progeny and parent-average testing breeding schemes based on three selection objectives applied over on 20 year period. Genetic gains in different traits were calculated from the regression of trait values on the selection index. The estimated lactation curves model parameters, and predicted lactation milk yield were significantly different between breeds, years and seasons. From four fit-statistics values, the CCC value was considered superior, and this value indicated that the Nelder model best represented the test day records. The net annual income for Holstein Pabna cattle was the highest (US229) and was lowest (US115) for Pabna cattle, while all other genotypes were intermediate. The economic values (EVs) of milk yield for all genotypes were similar (US0.32), and due to payment for milk volume only, the EVs of fat and protein were negative. EVs of liveweight, calving intervals and calving rate were negative, but survivability was positive in all genotypes. The parent-average testing selection scheme showed higher genetic gains than progeny testing. The highest (US15.80) genetic gain was obtained for milk yield when selection was for milk merit only. The study will assist in undertaking a genetic improvement programme for the increase of milk production in Bangladesh and thereby enhance food security.

Sisteme smeštaja i držanja životinja u intenzivnoj proizvodnji karakteriše visoka upotreba mehanizacije, velika gustina životinja i veliko opterećenje organizma. U takvim sistemima nije uvek moguće zadovoljiti osnovne potrebe životinja i one se tada teško prilagođavaju životnoj sredini. U sistemu zatvorenog stajskog držanja (staje sa sistemom vezanog držanja ili staje sa boksevima u kojima se sprovodi slobodan sistem držanja krava) posebno je važno voditi računa o zdravstvenom stanju papaka. . Zdravi ekstremiteti i dobra pokretljivost su od suštinske važnosti za dobrobit i dobru produktivnost goveda, posebno muznih krava. Ako se papci ne neguju na odgovarajući način nastaju brojna oboljenja lokomotornog aparata. Imajući u vidu učestalost pojave, ekonomski gubici uslovljeni raznolikom patologijom lokomotornog aparata su veoma značajni. Oni se ogledaju u preranom isključivanju krava iz proizvodnje, smanjenju proizvodnje mleka i troškovima lečenja. Problem šepavosti mlečnih krava može se izjednačiti sa problemom bolesti papaka, jer su upravo bolesti papaka najznačajniji uzrok šepavosti u intenzivnom držanju ovih životinja. Danas se smatra da bolesti papaka obuhvataju infektivne bolesti, bolesti interdigitalnog prostora i rožine papka i, kao poseban problem, pojavu laminitisa. U naučnoj literaturi u svetu postoje brojni podaci koji ukazuju da kod šepavosti nastaje znatno smanjenje količine mleka. Međutim, podaci koji se odnose na sastav mleka kod šepavosti, zastupljeni su u znatno manjem obimu. U našoj zemlji nema dovoljno novijih naučnih saznanja o učestalosti pojave šepavosti i njenom uticaju na osobine mlečnosti krava, kao i o najznačajnijim uzrocima i predisponirajućim faktorima šepavosti na našim farmama. Pri koncipiranju programa i postavljanju ciljeva istraživanja ove doktorske disertacije pošlo se od osnovne hipoteze da pojava šepavosti može znatno uticati na proizvodnju mleka, kao i da je izraženost šepavosti krava u korelaciji sa smanjenom količinom mleka krava simentalske rase...

Mikrodumblis Spirulina platensis – vienintelis gyvas organizmas, išgyvenęs žemėje, dėl unikalios biocheminės sudėties nepakitęs šimtus milijonų metų. Tai kruopščiai gamtos subalansuotas vitaminų, mineralų ir aminorūgščių rinkinys. Spirulina platensis labai turtinga aukštos biologinės vertės baltymų. Jie sudaro apie 70 proc. spirulinos sudėties. Šie baltymai gyvūnų labai lengvai pasisavinami, pasisavinimo koeficientas siekia iki 90 proc. Iš spirulinoje esančių 18 būtinų gyvūnams aminorūgščių 8 yra nepakeičiamos. 10 g sausos spirulinos medžiagos betakarotino yra tiek, kiek 10 kg morkų sausosios medžiagos. Spirulinos sudėtyje daug mėlynojo pigmento fikocianino, vienintelės pasaulyje žinomos medžiagos, galinčios stabdyti vėžinių ląstelių dauginimąsi. Gamalinolininės rūgšties yra randama tik piene ir spirulinoje. Dumblyje daug gliutamininės rūgšties, tirozino, cistino, arginio, tiamino, folinės rūgšties, būtinos hemoglobino susidarymui. Spirulinos sudėtyje labai daug gyvam organizmui būtinų mineralų ir mikroelementų – geležies, kalcio, natrio, kalio, vario, magnio, cinko, fosforo, seleno, vitaminų, karotino, nukleino rūgšties, fermentų ir kitų aktyvių medžiagų. Pasaulyje atlikti moksliniai tyrimai parodė, kad spirulina turi unikalių savybių: naikina daugelį virusų; kompensuoja vitaminų ir mineralinių medžiagų nepakankamumą; mažina riebalų kiekį kraujyje, profilaktiškai veikia prieš aterosklerozę ir koronarinius susirgimus; greitina žaizdų gijimą; skatina ląstelių atsinaujinimą;...

Darbo uždaviniai: Išsiaiškinti melžiamoms karvėms naudojamų pašarų racioną, jų sudėtis. Susipažinti su pašarų ruošimu. Išnagrinėti pašaro įtaką pieno produktyvumo rodikliams bei pieno baltymams. Apibendrinti tyrimų rezultatus, pateikti išvadas ir pasiūlymus. Darbas atliktas 2009-2011 metais X ūkyje. Darbo metu naudota mokslinė literatūros analizė, tyrimų statistinės analizės, duomenų sisteminimo ir apibendrinimo metodai. Tyrimo metu, iš gautų rezultatų nustatyta, kad ūkyje yra laikomos melžiamos karvės, kurios pasižymi aukštu produktyvumu. Taip pat ūkyje nusistovėjusi pašarų bazė, todėl galvijai gauna tą patį racioną ištisus metus, keičiasi tik raciono procentinė išraiška. Didžiausias pasikeitimas įvyko per pastaruosius metus, kadangi nuo laktacinio šėrimo buvo pereita prie vieno raciono, kuris taikomas visoms melžiamoms karvėms, neįskaitant jų laktacijos tarpsnių. Tai įtakojo žemesnius produktyvumo procentinės išraiškos rodiklius – 2009 metais vidutiniškai gauta 3,5% pieno baltymų 1 kg, o 2010 metais tik 3,32% pieno baltymų 1 kg. Tačiau išaugo bendras primilžis – 2009 metais iš vienos karvės per laktaciją buvo primelžta 7137,54 kg pieno, o 2010 metais iš melžiamos karvės gauta vidutiniškai 7413,97 kg pieno. Atsižvelgus į tyrimų rezultatus, siūlytume keisti raciono sudėtį, kadangi didelis baltymingų pašarų kiekis neigiamai veikia pieno sudėtį ir sukelia aukštą urėjos kiekį piene. Ištyrus 2009-2011 metais X ūkyje melžiamų karvių bandą, jų produktyvumą, naudojamą racioną,... [toliau žr. visą tekstą]

The tasks of this work: review the base and feed rations for dairy cows used; an explanation processes concentrates and other feed preparation, the distribution, rationing; identify impact of diets: feed meal; quantity and quality of milk production; economic effect; analyze data to cow productivity and reproduction; summarize the results, present conclusions and suggestions. The material was collected in 2009-2010, in the agricultural company „X“. Nature of the work is analytical and comparative. Scientific literature analysis, summarize and systematize statistics, research analysis methods are used during the work. During the study, the results indicate that the farm is considered to be dairy cows, which are characterized by high productivity. It is also holding a well-established base of feed, animals received the same diet throughout the year, changing only a percentage of the diet. The biggest change occurred during the past year, since lactation feeding was shifted to a diet, which applies to all dairy cows in addition to their lactation. It influenced the lower indicatorsof the productivity percentage - in 2009 received an average of 3.5% milk protein 1 kg, and in 2010 only 3.32% of milk protein 1kg. However, the total increase milk production - 2009 per cow per lactation milking was 7137.54 kg of milk in 2010 in dairy cows received an average of 7,413.97 kg of milk. According the given results, we suggest changing the composition of the diet, whereas the high protein... [to full text]

Darbo tikslas: išanalizuoti LSMU VA Praktinio mokymo ir bandymų centro pašarų, naudojamų melžiamų karvių šėrime, kiekybinius ir kokybinius rodiklius bei racionus ir karvių produktyvumą. Darbo uždaviniai: 1. Nustatyti kiek ir kokių pašarų sukaupta ūkyje melžiamų karvių šėrimui per pastaruosius 2 metus. 2. Išanalizuoti ūkio melžiamų karvių šėrimą ganykliniu ir tvartiniu laikotarpiais. 3. Išanalizuoti karvių produktyvumo ir pieno kokybinius rodiklius. Atlikus analizę buvo nustatyta, kad tirtame ūkyje daugiausiai laikoma Vokietijos juodmargių veislės (~50 proc.) ir Lietuvos juodmargių (~30 proc.) karvių. Daugiausiai bandoje buvo 1 – 3 laktacijų karvių (78,6 - 83,5 proc. visos bandos karvių). Vidutinis karvių produktyvumas 6835 kg pieno 4,23 proc. riebumo, 3,3 proc. baltymingumo; vidutinis somatinių ląstelių skaičius - 287 tūkst./ml. Atlikus melžiamų karvių šėrimui pašarų bazės analizę nustatėme, kad ūkis daugiausiai sukaupė vienmečių žolių siloso (873,9 t). Pašarų kokybės parametrų analizė parodė, kad siloso kokybės parametrų fermentacijos rodiklis kokybė ir stabilumas yra geri.

Pienininkystė yra svarbi mūsų krašto gyvulininkystės šaka. Pagal Lietuvos žemės ūkio ir kaimo plėtros strategiją pieninė galvijininkystė pripažinta viena iš prioritetinių žemės ūkio šakų. Mūsų šalyje 2006 metais pieno gamyba sudarė 23 % bendrosios žemės ūkio produkcijos. Pieną bei jo produkciją gamina daugiau nei 180 tūkst. ūkio subjektų. Pastaraisiais metais apie 50 proc. perdirbto pieno yra eksportuojama. Todėl labai svarbu gerinti šios gamybos efektyvumą. 2006 metais iš vienos karvės Lietuvoje vidutiniškai primelžta 4484 kg pieno arba 12 proc. daugiau nei 2002 metais. Nors šalyje vidutinis pieno primilžis iš karvės nuolat didėja, bet kol kas yra vienas mažiausių ES. Pienininkystei plėtoti yra palankios gamtinės sąlygos, šalyje veisiami galvijai gerai prisitaikę prie esamos pašarų bazės, jų genetinis produktyvumas gana aukštas. Tačiau dėl konkurencijos augant reikalavimams šalies ir užsienio rinkose, reikia siekti efektyvesnio pieno ūkio vystymo. Pieno gamyboje daugiau nei 60 proc. išlaidų tenka pašarams. Tod��l jų gamybos kaštai, kokybė ir maistingumas daro didžiausią įtaką pieno gamybos ekonomiškumui. Mažinant pieno gamybos savikainą, labai svarbu pasiekti aukštą pašarų maisto medžiagų konversiją. Efektyviau panaudoti pašarus ir, esant tiems patiems ištekliams, gauti daugiau produkcijos padeda įvairių pašarų paruošimo šėrimui būdų taikymas. Todėl, tobulinant produktyvių karvių šėrimo technologijas, ieškoma naujų, pažangesnių pašarų paruošimo būdų ir vienas iš jų gali būti... [toliau žr. visą tekstą]

Dairy farming has always been a primary important branch of cattle breeding in our country. Dairy farming is considered to be the essential direction of the strategy of agricultural development in the country of Lithuania. Dairy production made 23% of total agricultural production during the year of 2006. Milk and dairy production is produced by more than 180 thousands of agricultural subjects. About 50% of produced milk has been exported recently. It explains why economical efficiency of the production is especially important. Despite the fact that an average milk production per cow has been increasing recently, but it remains among the lowest ones in the EU. During the year of 2006 an average milk production per cow made 4484 kg of milk, 13% more than in 2000. It should be stated that our country is distinguished by quite favorable conditions for dairy farming. The cattle bred in the country are adjusted to the existing forage basis and the potential of their genetic productivity is rather high. Nevertheless, the higher requirements caused by the competition on the inner and foreign market force to seek for the more efficient development of dairy farming. About 60% of expenditure in milk production is spent on forage. That is why costs of forage production, quality and nutritional value mainly determine milk production economy. In order to decrease milk production costs it is primarily important to reach high conversion of forage nutritional substances. For more effective... [to full text]

Ūkininko karvės žiemą laikomos ant kilimėlių. Taikomas trumpasaitis laikymo būdas. Karvės vasarą išgenamos į ganyklas. Tiek tvartiniu, tiek ganykliniu laikotarpiu, karvės melžiamos automatizuotai į pieno linijas. Girdomos iš automatinių girdyklų, šeriamos du kartus per parą. Karvės tvartiniu laikotarpiu šeriamos koncentruotais pašarais, kukurūzų ir žolės silosu, šienu. Ganykliniu laikotarpiu jos gauna koncentruotųjų pašarų ir kultūrinių ganyklų žolės.

▼ ENGLISH ABSTRACT: Ruminal pH is the rumen condition that varies most. Studying the cause and effect of diurnal variation offers a means of improving ruminal conditions for rumen micro-organisms with subsequent improvements in fibre degradation, milk yields and milk composition. A research project was conducted to test the following hypothesis: feeding 6 kg (as is) concentrate per cow/day in different weight ratios, divided in a morning and an afternoon allocation, will result in an improved ruminal pH profile and a concurrent increase in fibre fermentation, milk yield and improved milk composition. The project was conducted at the Outeniqua Research Farm in the Southern Cape of South Africa. A randomized block design was used and two phases, viz. ryegrass phase and a kikuyu phase, were applied. Each phase was conducted during the growing season of the grass specie used as pasture. A rumen study and a production study were done in each phase. The rumen study used six cannulated multiparous cows per treatment, testing rumen pH, volatile fatty acid (VFA) concentration, in sacco degradation of neutral detergent fibre (NDF) and dry matter (DM). The production study used 42 multiparous cows, blocked according to days in milk (DIM), parity and milk yield, and cows were randomly divided into three treatment groups. The study tested milk yield, milk composition and changes in body weight (BW) and body condition score (BCS). Treatments consisted of a maize based concentrate supplement (6 kg per cow/day, as is) being fed to cows on pasture in different weight ratios between morning and afternoon allocation. Treatments used in the production study were: Concentrate fed: 5 kg during morning; 1 kg during afternoon • Concentrate fed: 4 kg during morning; 2 kg during afternoon • Concentrate fed: 3 kg during morning; 3 kg during afternoon The first and the last treatments mentioned above were used in the rumen studies. Results of the rumen study of the ryegrass phase showed no differences in ruminal pH between treatment means. The time (h) spent below the critical ruminal pH, i.e. 5.8, was of short duration (2.92 to 3.42 hours). The concentration of certain VFA’s differed at times, but the differences were not reflected in graphs and data of the ruminal pH. No differences were observed in in sacco NDF and DM degradation between treatment means. Similar results were mostly obtained in the kikuyu phase. No differences were found in either daily maximum, minimum or mean ruminal pH between treatment means. Though time (h) spent below the critical ruminal pH was of a long duration (7.1 hours) it did not differ between treatments. No differences were observed between treatment means for in sacco NDF and DM degradation. Results of the production study of the ryegrass phase showed no differences in milk yield or milk composition between treatment means. The same was observed in the kikuyu phase except that milk fat was higher in the treatment group that received the 3:3 kg ratio treatment. The fact that treatments did not differ in… Advisors/Committee Members: Cruywagen, C. W., Meeske, R., Stellenbosch University. Faculty of AgriSciences. Dept. of Animal Sciences..

▼ Subacute ruminal acidosis (SARA) has been associated with decreased milk production. During SARA, increased free ruminal lipopolysaccharides (LPS) and its translocation to blood have been measured. Acute phase response is stimulated by LPS, and cytokines reduce DMI and milk production. An avian-derived anti-LPS polyclonal antibody preparation (PAP-LPS) was developed to use as a feed additive. Our objective was to evaluate the effectiveness of PAP-LPS in decreasing the intensity of the inflammatory response and increasing milk yield in early lactation dairy cows. Primiparous (Pr; n = 174) and multiparous (Mu, n = 226) Holstein cows from one herd were randomly allocated to one of three treatments: 1) PAP-LPS (n = 55 Pr and n = 70 Mu), 2) PLC (n = 66 Pr and 77 Mu), and 3) CTL (n = 53 Pr and 79 Mu). Cows on PAP-LPS received a dose of 3 g/d of PAP-LPS via oral drench in a water suspension, while PLC received the same dose of inactivated PAP-LPS. Control cows did not receive any treatment. Treatments were administered from d 0 (calving) until 14 DIM. Milk production and components were recorded from d 0 to d 98 and weekly averages, Energy Corrected Milk (ECM) and components were used in a repeated measures analysis using the MIXED Procedure of SAS and a first-order autoregressive covariate structure. Feeding PAP-LPS increased ECM (p = .0023) during the first 98 DIM. Total milk production also increase (p = 0.04) when compared with CTL (3881 and 3769 kg, respectively), while only tended to increase it (p = 0.07) when compared to PLC (3785 kg). A week x treatment interaction was observed (p = 0.097) for weekly average milk production, and was greater (p < 0.05) for PAP-LPS vs. Control on weeks 3, 4, and 10. On week 6, cows fed PAP-LPS had greater (P < 0.05) milk production than both, PLC and CTL. No difference in haptoglobin, ceruloplasmin or health disorders was observed between groups. In conclusion, feeding PAP-LPS increased milk production in early lactation dairy cows. Mechanism of action is unknown, but increased dry matter intake was proposed.

▼ This study was conducted to assess the impact of dairy management training on milk yield and milk quality among small scale dairy farmers in Malawi. It was conducted against the background of failure by small scale dairy farmers in Malawi to realize the full potential of their dairy cows due to lack of dairy management skills. It was conducted in the Lilongwe and Mzuzu milk shed areas and six Milk Bulking Groups (MBGs) were selected using a purposive sampling method. Dairy farmers from three MBGs were trained in good dairy management practices that ranged from feeds and feeding, importance of water, milk handling, animal welfare, and farm hygiene to disease control, whereas farmers from the other three MBGs were not offered the training; they were treated as a control. The training was based on the Concern-Based Adoption Model (CBAM) that acknowledges that supporting people is critical for learning to bring change. Data was collected using a questionnaire for both the baseline (before training) and end-line survey (after training). Results indicated that training had a positive impact on the behavioral change of small scale dairy farmers on availability of water (46%, 12% and 33.3%), availability of feed (40%, 43% and 26.6%), cleaning of utensils (100%), barn cleanliness (46.7%, 37.5% and 33.3%) and the resultant increase in milk yields and reduced milk rejection (0%) by buyers in the trained MBGs. On the other hand, the untrained dairy farmers continued to practice unhygienic milk handling, which resulted in high milk rejection rate due to poor quality. At the same time the untrained dairy farmers continued to register low milk yields. The study results further showed that education level of dairy farmers had no impact on their behavioral change towards good dairy management practices. Similarly, the MBGs where farmers came from had no impact on their behavioral change. In conclusion, the study findings indicate that training plays a crucial role in changing dairy famer’s behavior towards good dairy management practices in Malawi. Emphasis ought to be placed on training in dairy management if milk yields and milk quality are to be enhanced. ( en ) Advisors/Committee Members: Dahl, Geoffrey E.

A partir da década de 1990 ocorreram, em todo o território brasileiro, crescimentos na produção e produtividade leiteiras. Esse fato é conseqüência das transformações ocorridas na cadeia leiteira, a partir desse período, as quais se sucederam com o fim do tabelamento do leite no ano de 1991, abertura comercial e consolidação do MERCOSUL. Uma das conseqüências diretas dessas transformações foi a crescente instalação de indústrias de laticínios multinacionais, em território nacional, dentre elas a Parmalat. Nesse sentido, o município de Carazinho, RS também apresentou crescimentos na produção e produtividade leiteiras. Como a Parmalat se instalou nesse município na década de 1990, a presente pesquisa procurou verificar o grau de influência tecnológica dessa empresa junto aos produtores de leite do local. Para tanto, escolheu-se, como amostra da pesquisa, um distrito de Carazinho denominado Distrito de São Bento. Dessa forma, verificou-se que essa empresa trouxe impactos para o contexto da produção leiteira no município, mas que o principal impacto está relacionado às exigências de qualidade do leite através da Instrução Normativa 51 (IN 51), lei esta promulgada, em todo o país, no ano de 2002.

From the 1990's occurred throughout the Brazilian territory, increases in milk production and productivity. This is a consequence of changes in the dairy chain, from that period, which is done with the end of the table of the milk in the year 1991, trade liberalization and consolidation of MERCOSUR. One of the direct consequences of these changes was the increasing installation of the dairy multinational industries in the national territory, including the Parmalat. Accordingly, the municipality Carazinho, RS also showed increases in milk production and productivity. As Parmalat is installed in that city in the 1990s, this research sought to verify the degree of influence that technology with the company's local milk producers. For both, chose, as the research sample, a district of Carazinho called District of St. Benedict. Thus, it was found that this company has impacts in the context of milk production in the municipality, but the main impact is related to demands for quality of milk through the Normative Instruction 51 (IN 51), enacted this law in any country, in 2002.

La maîtrise de la conduite d’élevage est essentielle pour produire des chevrettes qui expriment pleinement leur potentiel laitier au cours de leur carrière. Elle implique la détermination de phases clés au cours de la période de croissance, notamment pour la mise en place de la glande mammaire. L’objectif de cette thèse était de déterminer les effets d’un sevrage précoce combiné à différentes conduites alimentaires post-sevrage sur les performances zootechniques de chevrettes de race alpine ainsi que sur le développement de leur glande mammaire. Tout d’abord, nous avons montré qu’un sevrage précoce à 10 kg de poids vif n’affectait ni le développement corporel, ni les performances de reproduction, ni même la production laitière (PL) des chevrettesPar contre, un apport plus élevé de concentré pendant la phase d’élevage a augmenté le développement corporel et le poids de la glande mammaire. Toutefois, cela n’a impacté ni le développement du parenchyme mammaire au cours de la phase pré-pubère ou en début de gestation, ni même la proportion de Cellule Epithéliale Mammaire (CEM). La prolifération des CEM était identique quelle que soit la quantité de concentré ingérée. La PL n’a pas été modifiée par l’augmentation de l’ingestion de concentré. La modification de la concentration en énergie et en protéines du concentré en phase pré-pubère n’a eu d’effet ni sur les performances de croissance ou de reproduction, ni sur le développement de la glande mammaire. La chèvre semble donc s’adapter aux modifications de la conduite alimentaire sans pour autant que l’augmentation de croissanc

Control of husbandry management is essential to produce female goat kids that fully express their milk potential during their career. It involves the determination of key periods during growth, particularly for the mammary gland development. The objective of this thesis was to determinate the effects of early weaning combined with different post-weaning feeding strategies on the performances of alpine goat kids as well as on their mammary gland development. On the one hand, we showed that early weaning at 10 kg of body weight did not affect body development, reproductive parameters or milk production (MP). On the other hand, a high concentrate intake during the rearing period increased body development and the weight of mammary glands.However, this did not impact the development of mammary parenchyma during the pre-pubertal phase or at the beginning of gestation, nor even the proportion of Mammary Epithelial Cells (MEC). The proliferation of MEC was identical regardless of the amount of concentrate ingested. MP was not affected by increasing concentrate intake. Modifying the energy and protein concentration of the concentrate in the pre-pubertal period had no effect on growth, reproductive performance, mammary gland development or mammary parenchyma development. Therefore, goats seem to adapt to changes in feeding strategies without a negative effect of the increase in growth on their ability to produce milk.

▼ O objetivo deste trabalho foi traçar um diagnóstico da atual condição da produção de leite no município de Valença, maior produtor leiteiro do Estado do Rio de Janeiro, e através dos dados coletados junto a indústrias e propriedades rurais leiteiras prognosticar cenários futuros da atividade no município, frente a Instrução Normativa 51. A análise foi feita através de uma amostra de produtores registrados nas cinco indústrias captadoras de leite que concordaram em participar do estudo, somando 661 produtores. Dentre esses produtores foi determinada uma amostra estatística de 250 propriedades (α=0,05), com faixas de produção de até 50L, de 50 a 250L, e com mais de 250L de leite por dia, que foram sorteadas através do Microsoft - gerador de números aleatórios. A amostra foi avaliada através de um questionário contendo questões socioeconômicas dos produtores e ordenhadores, e questões relacionadas ao manejo da propriedade e produção, e por checklist com perguntas voltadas para tecnologia da obtenção de leite, com foco em sanidade, ordenha higiênica, cuidados do ordenhador e infraestrutura da propriedade. Para a interpretação dos resultados e elaboração do prognóstico foi utilizado o método SWOT (Strengths, Weaknesses, Opportunities, Threats). Os resultados revelaram uma agropecuária de caráter tradicional com mão-de-obra predominantemente familiar com pouca participação dos filhos; uma subutilização do potencial leiteira e da área de produção; falta de sintonia entre captadores e produtores, com oscilações no volume de leite e restrições em capacitação; infra-estrutura das propriedades é precária para a obtenção de leite com qualidade; a higiene no setor está muito aquém do esperado para a obtenção de um produto com qualidade diferenciada; os ordenhadores não têm ciência da atual legislação, e a maioria não sabe o que fazer para elevar a qualidade do leite. Embora Valença tenha um grande potencial o prognóstico da produção de leite no município é reservado. Para as indústrias e produtores que demonstraram conscientização da necessidade de adequação o prognóstico é positivo, pois estes estão se preparando para se tornarem competitivos no setor. Porém os que não se adaptarem serão massacrados gradativamente, sendo excluídos do mercado consumidor. Indicando a necessidade de mobilização dos industriais captadores de leite na região para que a IN51 seja explorada positivamente, tornando-se uma oportunidade de retomar as rédeas do setor e voltar a ser uma potência leiteira na região, para auxiliar este programa de capacitação posem ser criados vínculos com instituições técnicas como faculdade de medicina veterinária, escola agrícola e campo experimental da EMBRAPA Gado de Leite, todos sediados no município. Mas para que este processo tenha sucesso, os produtores precisam perceber que o comprometimento com a qualidade é realidade no setor de beneficiamento, e que sua resistência às mudanças implicará em sua exclusão do mercado.

▼ Three studies and a meta-analysis were conducted to determine the performance, nutrient digestion, and gas emissions of dairy cows fed diets with different starch concentrations (19 to 27% of DM). Study 1 evaluated the effects of reducing corn grain starch with non-forage fiber sources (NFFS, soybean hulls and beet pulp) in diets of soybean meal (SBM) or canola meal (CM). In study 1, reducing starch from 27 to 20% with soybean hulls and beet pulp had a negative effect on dry matter intake (DMI), milk yield and energy-corrected milk (ECM), regardless of the crude protein (CP) source. Those effects were explained by a low dry matter (DM) and organic matter (OM) digestibility in cows fed 19% starch. Study 2 explored through a meta-analysis the effects of reducing cereal grain starch with NFFS on the performance, nutrient digestion, and rumen fermentation of dairy cows. The meta-analysis indicated that when dietary starch intake increased from 1 to 9 kg/d, DMI responded quadratically, but milk yield, milk protein concentration, and milk lactose yield increased positively. Milk fat concentration however decreased linearly as starch intake increased in the cows. As dietary starch intake increased in the cows, the concentration of total volatile fatty acids (VFA) and acetate decreased linearly, but propionate, acetate to propionate ratio, isobutyrate, isovalerate, and valerate increased linearly. Increasing starch intake affected quadratically the DM digestibility, linearly CP digestibility, and negatively neutral detergent fiber (NDF) digestibility. Therefore, reducing cereal grains starch with NFFS has a negative effect on dairy cows performance. Studies 3 and 4 evaluated the effects of diets with conventional (CONV) and Brown midrib (BMR) corn silage with two starch concentrations (19 vs. 25% of DM) on performance and gas emissions, respectively. In study 3, cows fed BMR diets tended to have higher DMI than cows fed CONV corn silage diets. Cows fed BMR-25% had the greatest milk yield and ECM, but cows in BMR-19% produced the same amount of milk and ECM than cows with CONV corn silage in any starch concentration. These effects were explained by the increased digestibility of DM, OM, and CP in response to diets with 25% starch and the increased DMI with BMR corn silage. In study 4, diets did not affect DMI, milk yield, ECM, milk composition, nutrient digestion, and emissions of CH4, NH3, and CO2. However, cows fed BMR corn silage and 25% starch produced less CH4 and CO2 per kg of DM, OM, and starch digested than cows in CONV corn silage with any starch concentration, but cows fed 25% starch produced more NH3 and CO2 per kg of NDF digested. Overall, reducing starch with increasing NFFS has a negative effect on dairy cow performance and nutrient digestion, but including BMR corn silage improved those effects by increasing nutrient digestion. The combination of BMR corn silage and high starch diets have the potential to reduce gas emissions per kilogram of nutrient digested in lactating dairy cows.

▼ Survival of Escherichia coli O157:H7 in fermented dairy products has been attributed to acid-adaptation. Acid-adaptation enhances resistance to extreme acid pH and confers cross-protection to heterologous stresses. This study sought to investigate whether acid-adaptation confers cross-protection to lactoperoxidase (LP) system and lactic acid in Tryptone Soy Broth (TSB), and to determine the mechanism of cross-protection. Subsequently, cross-protection of acid-adapted E. coli O157:H7 to the combination of LP activation, heat and lactic acid treatments was determined in fresh goat milk. Finally, the effect of LP activation and E. coli O157:H7 survival on acid production during fermentation of traditional and commercial goat milk was investigated with indigenous cultures and single strain lactic acid bacteria (LAB) respectively. Acid-adapted E. coli O157:H7 strain UP10 showed high acid-resistance at pH levels 4.0 and 5.0 for up to 24 h in TSB at 25°C compared to non-adapted E. coli O157:H7. Acid-adaptation also conferred cross-protection against activated LP system and lactic acid challenge at pH 4.0 and 5.0. Results from fatty acid analysis and quantitative real time Polymerase Chain Reaction (RT-PCR) indicated that sigma S (RpoS)-independent systems were responsible for acid-resistance and cross-protection in TSB. Increase in the saturation of fatty acids, increased expression of outer membrane porin, OmpC, and activation of the glutamate decarboxylase system contributed to acid-resistance and cross-protection. Growth of acid-adapted E. coli O157:H7 strains UP10 and 1062 were inhibited in fresh goat milk compared to the non-adapted cells. Nonetheless, strain 1062 showed better growth and resistance to activated LP in fresh goat milk compared to strain UP10. LP activation alone did not significantly inhibit either acid-adapted or non-adapted E. coli O157:H7, but it sensitized E. coli O157:H7 cells to sub-lethal heat treatment at 55 and 60°C. The combination of heat treatment at 60°C, LP activation and lactic acid at pH 5.0 had a greater inhibitory effect on both acid-adapted and non-adapted E. coli O157:H7, but the acid-adapted strains displayed cross-protection against combined treatments. This indicates that non-adapted E. coli O157:H7 can survive a certain threshold of stresses unscathed. Below that threshold, acid-adaptation may be detrimental to survival. LP activation did not inhibit growth and acid production by single strain and indigenous LAB in the processing of commercial and traditional fermented goat milk products. LP activation however inhibited E. coli O157:H7 in both the commercial and traditional goat milk products although E. coli O157:H7 had become acid-adapted during the fermentation process. E. coli O157:H7 inhibition could be due to the combination of LP activation, low pH, fermentation time and antimicrobial compounds present in the milk or produced by the LAB during milk fermentation. Results from this study suggest that while acid-adaptation protects E. coli O157:H7 under harsh conditions, it… Advisors/Committee Members: Prof P Jooste (advisor), Prof E Buys (advisor).
