▼ Characterization of village chicken phealth and management practices in the Amatola Basin of the Eastern Cape Province, South Africa By Njongenhle M. B. NYONI The majority of rural households in South Africa own village chickens which contribute significantly to their livelihoods. However, limited research has been conducted to characterize, understand and develop village chicken production in South Africa. This hinders the designing and implementation of village chicken-based developmental programmes that will benefit farmers in rural areas. Thus, it is imperative to initiate studies to describe village chicken production. This study was conducted to characterize village chicken production in Amatola Basin of the Eastern Cape Province of South Africa. Baseline information was gathered using a questionnaire survey of 81 identified from 7 out of 13 villages using snowball sampling technique. Consequently, 20 households were selected to participate in a monitoring study (from July 2010 to June 2011) through purposive sampling. Most (60%) chicken flocks were owned by women and mainly raised to meet household food requirements. Some (28.4%) farmers occasionally sold cocks and hens to neighbours, at an average price of R50 (USD7.55) per bird, as a way of culling their flocks and generating income. However, village chickens were mainly kept for food security rather than for their terminal benefit of cash. Although, all chicken flocks were produced under the scavenging feeding system, most (96%) flocks were provided with supplementary feed and drinking water. A majority (93.8%) of households also provided some form of shelter for their chickens. The mean cock to hen to chick ratio was 1:5:15. On average, iii each household owned 17 (±2 S.E.M.) chickens, and hens had 3.3 clutches per annum. Chicks hatched and chickens received as gifts represented the flock entries, while exits included mortality, consumption, sales and gifts or donations, in that order. Generally, both exits and entries were more pronounced in the summer season than in other seasons. Most (81.5%) farmers experienced chicken losses due to predation and health related problems. Parasitism ranked high amongst the village chicken health challenges. During monitoring, the endoprasites identified included nematodes, cestodes and protozoa. Coccidia were the most prevalent endoparasites. The chickens were also infested with a variety of ectoparasites namely: mites, lice, fleas and ticks. The sticktight flea Echidnophaga gallinacean was the most prevalent species. Although ectoparasite infestations were most pronounced in summer, almost all chickens harbored one or more of these parasites throughout the study period. The prevalence and intensity of parasite infestations were significantly (P<0.05) higher in the summer season compared to the other seasons. This was followed by the autumn, spring and winter seasons, respectively. The majority (77.5%) of farmers resorted to alternative remedies, mostly medicinal plants, for treating diseases and controlling parasites.… Advisors/Committee Members: Prof. P. J. Masika.

▼ Objectives of this study were to examine effects of dietary pyrrolizidine alkaloids (PA) on copper and vitamin A metabolism in the chicken which are very susceptible to the hepatoxic effects of PA and Japanese quail which are highly resistant to PA. Also, the possible interaction between copper and vitamin A in the two species and effect of PA on retention of previously stored vitamin A in the chicken were investigated. Three experiments were designed. Experiment 1 was to examine the effect of feeding the PA-containing plant tansy ragwort (TR)(Senecio jacobaea) on tissue levels of copper and vitamin A in the chicken. Experiment 2 was to investigate if dietary PA affected the retention of previously stored vitamin A in the chicken. Experiment 3 was to determine if hepatoxic effects of PA are necessary to influence copper and vitamin A metabolism in Japanese quail. In experiment 1, a 2x2x2 factorial design with dietary 0 and 5% TR, 0 and 250 ppm copper, and 0 and 25,000 IU/kg diet vitamin A was used. The results showed that body weight gain was reduced (P < 0.01) in birds fed TR. Both serum and liver copper concentrations were markedly increased (P <0.01) in the TR-fed group with 250 ppm copper supplement. Zinc concentrations in the serum and liver were significantly decreased (P <0.05) in the TR-fed groups compared to TR-free groups. Liver iron was increased (P <0.05) in the TR-fed birds. The serum vitamin A levels were significantly decreased (P < 0.01) in all TR-fed groups. The ranges of decrease were from 62 to 72 % in four TR -fed groups. The liver vitamin A concentrations were also significantly decreased (P <0.05) in TR-fed groups without vitamin A supplement. The effects of PA on liver and blood vitamin A concentration may reflect PA inhibition of synthesis of retinol-binding proteins, or impaired vitamin A absorption from reduced biliary excretion. There was no interaction between dietary copper and vitamin A levels and tissue concentrations of these nutrients. In experiment 2, a two period experiment was carried out. In the first period, two groups of chicks were fed a diet containing 25,000 IU vitamin A/kg diet for two weeks followed by a control or TR-containing diet for four weeks. Blood samples were taken at 4 day intervals for 24 days. It was found that by day 8, serum vitamin A levels were significantly depressed (P <0.05). After 24 days of PA exposure, serum vitamin A levels were reduced by 55 % and 8.5% in the TR-fed group and the control group, respectively. Liver concentration of vitamin A was increased (P < 0.05) at day 24 of TR feeding, while liver vitamin A concentration in birds fed the control diet was decreased by 13% over the same period. The results indicate that PA inhibit the mobilization of previously stored vitamin A from the liver, probably by inhibiting hepatic synthesis of retinol-binding proteins. Experiment 3 was a 2x2x2 factorial design with added 0 and 5% tansy ragwort, 0 and 250 ppm copper, and 0 and 25,000 IU/kg diet vitamin A. The results… Advisors/Committee Members: Cheeke, Peter R.

▼ A comparison of the various endocrine glands, in addition to other anatomical measurements, was made on 19 normal and 21 dwarf 2-3-month-old females and 20 normal and 20 dwarf 7-13-month-old females of the White Leghorn breed. At both ages, dwarfs weighed significantly less and had significantly shorter shanks than normals. Comb weight and comb area (L X H) were significantly larger in normals than in dwarfs 7-13 months of age, but no significant difference was found in the 2-3 month age group. Ovaries in the 2-3 month age group were heavier in normals than in dwarfs, due to greater gonadotropin secretion in relation to body size. The divergent results in weight of the hypophyses on an absolute and a relative-to-body-weight basis may be attributed to the algebraic sum of synthesis storage and liberation of hormones by this gland. Also, absolute and relative weights of the adrenals did not always coincide in both age groups, which may be attributed to environmental factors influencing the release of ACTH from the hypophysis. The normals had significantly heavier thyroids than dwarfs. on an absolute and on a relative weight basis at both ages, which does not necessarily indicate a hyper- or hypothyroid condition in the latter group of birds. Normals secreted significantly more thyroxine than dwarfs at 7-13 months of age; whereas, no significant difference was found between these two types of chickens at 2-3 months of age, as determined by epithelial cell height. The significantly smaller colloid and follicle diameter found in thyroids of dwarfs than of normals may be attributed to the lower gland weights in the former group. Bioassay of the hypophyses from these chickens was conducted in immature, hypophysectomized, female rats. Dwarfs did not differ significantly from normals in STH activity, according to the tibia test, body weight gain and tail length. Greater epiphyseal plate responses were obtained from hypophyses of growing chickens. Thymus weight varied with dosage, which is attributed to several hormones acting on this gland. The normals had a significantly higher hypophyseal ACTH content than dwarfs 2-3 months of age, which is believed to be due to the hormone content of the hypophyses at the time of removal, rather than to dwarfism. Also, the younger birds were observed to have a higher ACTH content than older birds, which may be due to storage of this hormone in the hypophysis during the growing period. Dwarfs did not differ significantly from normals in gonadotropic activity at both ages, as evaluated by ovary, oviduct and uterus weight response in the assay rats. However, the older birds were observed to have higher gonadotropic activity than younger birds, as determined by ovary, oviduct and uterine weight and vaginal openings in the rats. No significant difference in FSH content of the hypophyses of dwarfs and normals of both ages was found, using ovarian follicle diameter. Observation of the interstitial cells in the rat ovaries revealed no difference between… Advisors/Committee Members: Bernier, Paul E. (advisor).

▼ A cross sectional study was conducted from January 2015 to May 2015 to characterize the pathological changes and to determine seroprevalence of IBD and its associated risk factors in chickens in and around Bahir Dar. The clinical signs observed in IBD infected chickens were whitish diarrhea mixed with blood, ruffled feather, and massive death within short period. The necropsy findings were petichial hemorrhage in bursa of fabricius, kidney, thymus, spleen, thigh and pectoral muscles. Bursa of fabricius became edematous in serosa and mucosal part, whitish-creamy and atrophied as the course of the disease progressed. Kidney became pale and ureter was turgid with urate in a numbers of cases. The histopathological changes in this study revealed that edema of bursa of fabricius, formation of cystic follicles, depletion of lymphocytes, fibrosis and follicular architecture lost. Severe, moderate and mild lesion score were observed in bursa of fabricius. Infiltrations of heterophils were noted both in lymphoid and non lymphoid tissues. Depletion of lymphoid cell in germinal center of spleen and total depletion of lymphoid cells were encountered in thymus gland. The kidney tubules were filled by exudates and necrotized cuboidal cells. Sera collected from a total of 320 chickens were subjected to IELISA test and disclosed an overall prevalence of 51.56% (CI: 45.95 – 57.14) in study area. The seroprevalence of IBD among chickens showed a statistically significant difference (P<0.05) among study sites namely Andassa (72.73%), Gombat (50%), Wonjeta (47.69%), Meshenty (44.44%) and Bahir Dar (42.42%). The susceptibility of chickens to IBDV revealed a statistically significant difference (P<0.05) among different breeds where Koekoek was found more prone to IBD infection with seroprevalence of 67.11% followed by Bovans brown (57.69%), local breeds (48.31%), and Bovans white (40.28%). The seroprevalence of IBD was also significantly associated (P<0.05) with the age of chickens and among farm systems. These studies clearly indicated that IBD infection is a common and wide spread problem affecting a number of chicken breeds under different management systems and hence an urgent control intervention should be in place.

▼ Helminthosis is a very important disease condition aflfecting the poultry industry, especially the traditionally reared free ranging chickens. The traditionally reared poultry farming system constitutes over 50% of the poultry industry in Zambia (Hameenda, 1985), however, very little work has been done to establish the extent of helminth infection in the Zambian free-range poultry industry. The aim of this research therefore was to investigate various aspects of helminth infections in poultry with the hope of collecting base line data and suggesting control measures that will ultimately help reduce the suspected high prevalence of helminths and thus increase the productivity of the poultry industry in general.The prevalence of the gastrointestinal nematode parasites was evaluated in poultry in three management systems in and around Lusaka and in Shibuyunji area, Mumbwa District, Zambia. A low prevalence (2.5%) with only two nematode species {Ascaridia galli and Heterakis gallinarum) was observed in the commercially reared chickens. A level of 12.5% was observed in the semi-intensively reared chickens with Ascaridia galli, Gongylonema ingluvicola, Heterakis gallinarum and Tetrameres americana. Finally, a prevalence of 100% was obtained in the traditionally reared free-ranging chickens. This included the above six mentioned nematodes ^hxs Acuaria hamulosa and Allodapa suctoria. The prevalence in the latter management system was significantly (p < 0.01) higher than in the commercial and the semi-intensive management systems.These observations do suggest that the type of management system practiced greatly influence the prevalence and incidence of helminth infections.The effects of helminthosis on the weight gain in the traditionally reared chickens was observed with one group treated with Levamisole (25% m/v) and the other group a non-treated control. The mean weight of the two groups at the end of the 15 weeks study were, 623±574 g in the untreated control group and 812.8±51.4g in the treated group. There was a strong negative correlation (r =-0.780, r^= 0.61) between the weight gain and the worm burden in the untreated control group and a weak negative correlation (r =-0.261, r^ 0.07) between the weight gain and the worm burden in the treated experimental group. It was noted that anthehnintic treatment of young birds would improve the weight gain capacity of the flock of a traditional farmer.An evaluation study was carried out on the efficacy of a commonly used anthelmintic in Zambia, piperazine (lOOOmg P.HC1) in comparison with two other anthelmintics i.e. albendazole (75% m/v) and levamisole (25% m/v). Percentage efficacy against Ascaridia galli was 100%, 100% and 52.4%, for albendazole, levamisole and piperazine respectively. Against Heterakis gallinarum was 96.2%, 89.3% and 27.9%, and for Allodapa suctoria was 95.1%, 89.6% and 28.6% for albendazole, levamisole and piperazine respectively. The mean worm counts for the groups were, control (70.59), albendazole group (3.55), levamisole group (9.67) and piperazine…

▼ Four 21-d experiments were conducted to compare soybean meal (SBM) from high oleic to parent soybean cultivars on growth performance, energy and ileal AA (IAA). Soybean meal was prepared by laboratory-scale mechanical extraction. Two replicate chick assays (Exp. 1 and 2) with similar treatments were conducted to evaluate the growth efficiency. In Exp. 1 and 2, 50 d-old male broilers (Ross 308) were randomly placed in battery cages and allocated to 2 dietary treatments with 5 replicates and 5 birds per replicate. The SBM sources consisted of cold-pressed conventional SBM (CON) and cold-pressed high oleic SBM (HO). All SBM sources were heated in a forced-air oven at 120 degrees C for 20 min. Diets were formulated to meet or exceed NRC (1994) and Aviagen nutrient requirements for Ross 308 in Exp. 1 and 2, respectively. Broilers were weighed and feed disappearance measured on d 7, 14, and 21 in Exp. 1, and on d 10 and 21 on Exp. 2. Two assays (Exp. 3 and 4) were conducted to determine IAA digestibility and apparent metabolizable energy (AME) in Exp. 3 or ileal digestible 24 energy (IDE) in Exp. 4. In Exp. 3 and 4, 100 d-old broilers randomly allotted to 2 dietary treatments with 10 replicates and 5 birds per replicate. Chicks were fed a corn-SBM based diet for 17 d, and a diet was developed by substituting the soybean cultivars in a corn starch-dextrose basal diet and fed from d 18 to 21. A nitrogen-free diet was fed to determine ileal endogenous AA losses. Titanium dioxide (0.5 percent) was included in all diets as a digesta flow marker. Excreta and ileal samples were collected on d 21. Statistical analyses were performed as a completely randomized design using PROC GLM of SAS with significance level set at P less than or equal to 0.05. In Exp. 1, chicks fed diets containing HO had decreased ADG (P less than 0.05; 25.3 vs. 29.4 g) and increased feed:gain ratio (P less than 0.05) from d 0 to 14 (1.71 vs. 1.56) and d 0 to 21 (1.54 vs. 1.47), compared with chicks fed CON diet. In Exp. 2, chicks fed HO had lower BW at d 10 (P = 0.028; 143 vs. 153 g), lower ADG from d 0 to 10 (P = 0.030; 10.90 vs. 11.90 g), and greater feed:gain ratio from d 0 to 10 (P = 0.043; 1.55 vs. 1.45) compared with chicks fed CON diet. In Exp. 3, AA digestibility did not differ among all essential AA. There were no differences in AME (kcal per kg) from SBM between CON and HO, with values of 2,921 and 2,901 (P = 0.73), respectively. In Exp. 4, the digestibility of glutamic acid (P = 0.026; 94.4 vs. 95.2 percent) and arginine (P = 0.008; 94.4 vs 95.4 percent) from HO were lower than CON; however, the IDE of CON and HO were similar (3,419 and 3,343 kcal/kg; P = 0.08), respectively. In conclusion, although there were no differences in nutrient digestibility, in conditions of this study, broilers fed HO had impaired growth performance, mainly from 1 to 14 d of age.

▼ ENGLISH ABSTRACT: In the broiler industry, it has become common practice to supplement diets with feed grade phosphates and in doing so provide sufficient available phosphorus to meet the birds’ requirements. Supplemented phosphates provide a large portion of the total available phosphorus within the diet and any small differences in the availability could have significant effects on whether or not the bird meets its nutritional requirements for phosphorus. If the bird’s phosphorus requirements are not met, the implications are detrimental, not only to the bird but also to the farmers’ flock productivity. Two experiments were conducted; the objectives of the first experiment were to assess the phosphorus bioavailability and nutrient and mineral coefficient of total tract digestibility (CTTD) of a feed grade inorganic phosphate source, defluorinated phosphoric acid by means of a digestibility study. Five treatments were used in this trial. Two diets made the basis of the treatments, a summit diet, only supplemented with mono-dicalcium phosphate (MDCP), and a dilution diet, only supplemented with phosphoric acid. These were mixed in ratios of 100:0, 75:25, 50:50, 25:75: and 0:100 respectively. The second experiment assessed the effect of supplementing broiler diets with either defluorinated phosphoric acid or defluorinated and desulfonated phosphoric acid. The control diet used was supplemented with MDCP. The phosphoric acids were included in the diets at two inclusion levels, based on dietary total phosphorus levels and available phosphorus levels. Furthermore, during the mixing of the diets, the phosphoric acids were either added to the diets’ grain component (maize, soybean 46 and full fat soya meal) before any of the remaining macro minerals were added or added to the diet last after all the other ingredients had been sufficiently incorporated. These treatment differences resulted in eight test dietary treatments. The objectives for this experiment were threefold: (i) to evaluate the effects of the dietary treatments on production parameters; (ii) to determine the influence of the dietary treatments on carcass characteristics and meat quality and (iii) to investigate the effect of the dietary treatments on broiler organ weights, intestinal pH and bone parameters. The phosphorus bioavailability of the phosphoric acid (PA) showed to be greatest and revealed high digestibility values of all nutrients and minerals. For the second experiment, both PAs resulted in ideal measurements of the production parameters (live weight, cumulative weight gain, cumulative intake, feed conversion ratio, average daily gain, European production efficiency factor and protein efficiency ratio) regardless of when the PA was added to the diet during mixing. However, when acid inclusion levels were based on the diet’s total phosphorus, these values decreased significantly irrespective of the method of mixing. Liveability was also affected by treatment differences, as a result of sodium poisoning in the control diet on day 14 for… Advisors/Committee Members: Pieterse, Elsje, Hoffman, L.

▼ Introduction: In the Northern region of the Northern Province, there is an increase in the number of small-scale and semi-commercial farms in all sectors of agriculture. This includes the production of grains, vegetables, fruits and livestock. Broiler production seemed to be a much-preferred alternative of development in community based projects and emerging farmers have shown keen interest. This is because broiler production requires less space than ruminants and is ready for human consumption within a very short period of time. Poultry production provides a constant source of income and protein with a big customer demand. By the year 2000, broiler production is expected to reach 4000 million and 7.5 million tons of poultry feeds in the world. Many countries have initiated programs aimed at improving small-scale poultry as a means of helping to bring socio- economic benefits to rural communities (Panda, 1989). In order to feed the ever rising population of 4.9 million in the Northern Province (1996 Census), there must be an increase in the production of broilers as a primary source of top quality animal protein. With the high unemployment rate (46%) in the Northern Province, self- employment projects are needed which comply with agro- processing. More than 90 community projects based on poultry production in the Northern region of the Northern Province had been established in order to reduce the high rate of unemployment. Today more people have engaged themselves in community projects especially in poultry production than ever before. Some of the constrains of broiler production at both small-scale and semi-commercial farming condition includes inadequate ventilation system. Lack of suitable health care facilities and frequently the absence of efficient marketing structures form part of the obstacles to the rapid development of poultry production. Feed costs which remain the highest input cost in the production of broilers represent between 60 to 70% or more of the total costs of broiler productions (Benyi and Habi, 1998). Lack of management skills and training for small and semi-commercial farmers makes it difficult to obtain optimum performance. The objective of this study is to evaluate the performance of broilers as influenced by environmental factors under small.

▼ Introduction : World poultry meat consumption consists of three major segments: broilers, turkeys, and other poultry which includes spent egg layers, spent breeder hens/males, ducks, geese, guinea-fowl, pheasants, quail, ratites, ostriches and emus. Broilers clearly dominate the world poultry consumption contributing about 70 percent to the world poultry market. Turkeys account for about eight percent while other poultry provides the balance of 22 percent (Roenick, 1998). The world broiler industry has been, and continues to be a very dynamic industry. It has been typified with unprecedented growth in terms of production. In 1961, the world produced 6.5 billion broilers. By 1990, the total annual production was a little over 27 billion broilers and by 1996, total world production had grown to 35.3 billion (Van der Sluis., 1999). This represents a fivefold increase in 35 years, and it has not stopped growing since, with world production surpassed 38 billion in 1998 (Van der Sluis., 1999). In Africa the human population was estimated to be 819.9 million, while the total poultry population of the continent was estimated as 1.133 million chickens, 15 million ducks and seven million turkeys in 1998. Production scale being 1.781701 metric tones (MT) of hen eggs, 2.269000 MT of chickens’ meat, 32.824MT of turkey meat and 52.989MT of duck meat (Gueye, 2000). Commercial poultry products are also imported and exported. For example, 12.000 metric tons of poultry meat was estimated to have been exported from South Africa in 1999, whereas 87.000 and 10.000 metric tons of poultry meat was imported into South Africa and Egypt, respectively (Gueye, 2000). In South Africa poultry production is moving toward the 21st century with the potential for increased development being greater than any other sector of the agricultural industry. The small-scale to medium-scale or semi-commercial farmer is becoming a role-player that needs to be serviced by the poultry industry (Fourie, 2000). The industry will have to take up the challenges that are facing an entrepreneur starting with a poultry venture. The poultry industry has developed from a humble beginning at the turn of the century into a multi-million Rand enterprise where protein is provided through the commercial and small marketing sector (Fourie, 2000). Some of the larger commercial companies market three million birds per week. It is estimated that the commercial company sector is responsible for 75 to 85 percent of production and marketing of white meat in this country whereas the small-scale and medium-scale or semi commercial poultry production enterprises provide 20 to 25 percent of the white meat through the sales of slaughtered and live poultry sale to rural, peri-urban and urban settlements (Fourie., 2000). Small-scale and semi-commercial broiler production is developed by entrepreneurs who buy day-old chicks from the big commercial hatcheries, rear them to the age of five to eight weeks and sell them through a marketing network or small outlets. The small-scale consist of…

▼ In broiler chickens, hepatic lipid metabolism plays a significant role in whole body and muscle fatty acid (FA) incorporation. Flax seed is a rich source of α-linolenic acid and can be used to increase n-3 FA in poultry meat. Previous studies have shown that flax seed in combination with carbohydrase enzymes in broiler diets enhances long chain (LC) n-3 FA in hepatic tissue. Three experiments were conducted to evaluate the effect of flax seed and carbohydrase enzyme addition on production performance, total tract lipid digestibility, hepatic fatty acid composition, liver lipid class distribution and lipid metabolism in broiler chickens. In Experiment 1, broiler chicks were placed in individual cages and fed isocaloric, isonitrogenous corn-soy diets: Control, Flax (10% flax), and Flax+E (Flax+0.05% enzyme). The diets were fed for a period of 42 days. Total tract digestibility of lipids and FA were assessed from day 19 to 21 of growth. There was no effect of diet on production performance characteristics, including final body weight (BW) or yield of cut-up parts. Flax-based diets reduced total tract lipid digestibility (p<0.001), increased excreta dry matter and total lipids compared to Control (p<0.05). Addition of enzyme led to an increase in digestibility of n-3 FA when compared to Flax (p<0.001). Total lipids in the liver tissue was higher in Flax-fed birds (p=0.044). Liver tissue of Flax and Flax+E were enriched with n-3 FA along with a reduction in n-6 FA (p<0.05) compared to Control. Hepatic tissue of Flax+E exhibited higher monounsaturated FA compared to Flax and Control (p<0.05). In Experiment 2, tissue (heart, cardiac) was collected from broiler chicks raised in floor pens and fed isocaloric, isonitrogenous corn-soy diets: Control, Flax (15% flax), and Flax+E (Flax+0.05% enzyme). The diets were fed for a period of 35 days. Hepatic and cardiac tissue lipids were subjected to triglyceride (TAG) analysis. Lipid classes (TAG; phosphatidylcholine, PC; phosphatidylethanolamine, PE) from hepatic crude lipid extract were separated and subjected to FA analysis. TAG was lowest in hepatic tissue of Flax and Flax+E compared to Control (p=0.001). Flax+E TAG was observed to incorporate significantly lower total saturated FA and increased monounsaturated FA compared to Control. Total n-3 FA were greater in all lipid classes in Flax+E compared to both Flax and Control (p<0.05). A 3-fold and 2-fold increases in LC n-3 FA was observed in PE and PC, respectively of Flax+E compared to Control. In Experiment 3, liver tissue collected from Experiment 1 were subjected to lipid metabolism related gene expression studies. Expression of peroxisomal acyl-CoA oxidase 1 (ACOX1), acyl-CoA synthase long-chain family member 1 (ACSL1), and carnitine palmitoyltransferase 1 A (CPT1A) was up-regulated in Flax+E birds (p<0.05). Fatty acid synthase (FASN) and acetyl-CoA carboxylase α (ACCA) were significantly reduced in Flax and Flax+E (p<0.05).

▼ The study and entire laboratory works ware conducted from December 2014 to April 2015 in National Veterinary Institute, Bishoftu, Ethiopia. A total of 120(20 chickens from four farms and 40 backyard chickens from commercial farms and local markets respectively) were used for the study. The chickens were slaughtered at national veterinary institute postmortem room and tracheal, air sac and lung samples were collected from slaughtered chickens. Isolation and molecular characterization of Mycoplasma gallisepticum strains was done based on standard recommended methods. And the objective of this study is to identify local strains and to undertake molecular characterization of Mycoplasma gallisepticum circulating in the chicken population of farms in Bishoftu. This can help to device strategies in controlling the disease mainly through developing more effective vaccine which will replace the currently being imported Mycoplasma gallisepticum vaccines by some farmers. Then propagation was undertaken using appropriate culturing procedure. The mycoplasmal DNA was extracted and polymerase chain reaction was conducted for amplification of Mycoplasma gallisepticum Mgc2 gene. Amplified deoxyribonucleic acid fragments were analyzed by conventional 2% agarose gel electrophoresis incorporating appropriate size markers, followed by examination under Ultra violate light. The Polymerase chain reaction product for Mycoplasma gallisepticum was 185 bp. A number of 3 pooled (from 30 chickens) mycoplasma isolates were recovered from chickens in 2 farms and from back yard chickens in Bishoftu. Of these, 3 Mg isolates were identified using growth inhibition and rapid serum agglutination tests. Among six isolates (3 pooled and 3 lyophilized National veterinary institute isolates), (50%) or 3 samples were found strong positive and (50%) or 3 samples were weak positive to Mycoplasma gallisepticum as they gave 185 bp products, similar to the positive control when visualized electrophoretical analysis. Finally oil based Inactivated Mycoplasma gallisepticum vaccine was produced in suitable clean and secure accommodation, well separated from production facilities of National Veterinary institute. In this study, formaldehyde inactivated Montanide ISA70 based Mycoplasma gallisepticum vaccine from the Polymerase chain reaction confirmed positive from Samuel local isolate of National Veterinary Institute was prepared and evaluated in chickens. The amount of immune antigen per 0.5ml of the dose was 10 7 Colony forming units of the bacteria. At the age of 16 weeks, the chickens were randomly divided into three groups (A, B and C), each having twenty birds. Each bird of group B was vaccinated group of imported- live vaccine with 30μl dropped in the eye and each bird of group C was inoculated with 0.5 ml indigenous or trial vaccine subcutaneously at mid neck region and group A was used as a control.After challenge test, among non-vaccinated chickens ( control or group A) 2 chickens were died (10 %), thicken and cloudy appearance of the air sac showed 18 (90%… Advisors/Committee Members: Dr. Badaso Mamo (advisor).

▼ Previous research has shown that sperm mobility is a primary determinant of fertility in fowl. Sperm mobility denotes the net movement of a sperm population, and males can be characterized by phenotype. Sperm acylcarnitine content differs between low and high sperm mobility phenotypes. The release of acyl groups from phospholipids within sperm depends on the action of the enzyme phospholipase. Inhibition of phospholipase A₂ (PLA₂) activity eliminates sperm motility, thereby rendering sperm immobile. This research was performed to test whether cPLA₂ was expressed differentially in roosters characterized by low or high sperm mobility phenotype. cPLA₂ expression in the two phenotypes was compared using reverse transcription - polymerase chain reactions. The cDNA amplified was a 352 nucleotide fragment encoding the Ca²⁺ binding domain of cPLA₂. Two sequential experiments were performed using full- and half-sib roosters. In the first experiment (n=3 full sibs per phenotype), cPLA₂ expression was greatest in testes from the high phenotype relative to ß-actin or 18S rRNA (P < 0.05 and P < 0.0057, respectively). The average cPLA₂ : ß-actin ratios for high and low sperm mobility phenotypes were 0.63 ± 0.260 (mean ± SEM) and 0.32 ± 0.123, respectively. The cPLA₂ : 18S rRNA average ratios were 0.74 ± 0.158 and 0.38 ± 0.135 for high and low sperm mobility phenotypes, respectively. In the second experiment (n=6 half-sibs per phenotype), the high mobility phenotype also showed greater (P < 0.023) expression of cPLA₂ relative to the 18S rRNA control with averages of 0.74 ± 0.141 and 0.49 ± 0.104 for high and low sperm mobility phenotypes, respectively. Moreover, sequence analysis of the nucleotide fragment showed no difference between phenotypes. cPLA₂ expression clearly differed between sperm mobility phenotypes. It was concluded that a difference in the regulation of cPLA₂ mRNA expression contributes to variation between lines of roosters generated by selection for sperm mobility.

▼ The role of synthesis and degradation in controlling enzyme concentrations was studied. Concentrations of chloride and arginine were determined for blood and liver at various stages of development from the embryo to the 8 day old chicken. The chloride concentrations were used to obtain the volume of extracellular blood in the liver. Using these values together with the data for total arginine, it was possible to calculate the intracellular and extracellular arginine concentrations in the liver. Extracellular arginine represented. 19%, 15% and 26% of the total arginine in the 14 day embryo, 1 day old. chick and 8 day old chick respectively. The kinetics of incorporation of L-(guanido- 14 C)-arginine and. L-valine- 14 C(u) into the blood amino acid pool and intracellular liver amino acid pool of the chick during various stages of development were measured. Intravenous injection of isotopic amino acid leads to results similar to a pulse labeling pattern, since more than 80% of the tracer is consumed after 60 minutes. The time-integrated radioactive amino acid pools were determined for each age of chick. Thirty minutes after injection of radioactive arginine or valine, 40% of the radioactivity remaining in the amino acid pools is found in compounds other than arginine or valine. These results are indicative of probable matabolism of these amino acids into other compounds. Xanthine dehydrogenase concentrations and the wet weight of liver also were measured during development. The liver wet weight increases most rapidly in the embryo. The enzyme activity is low in the embryo, rises rapidly upon hatching and reaches a high level by the eighth day after hatch. The rate constants of synthesis and degradation were determined for xanthine dehydrogenase during chick liver development, by purifying the labeled enzyme and measuring the rate of incorporation of label from arginine or valine into the protein. The rate constants for synthesis using L-(guanido- 14 C)-arginine are 3.7 x 10- 12 2.8 x 10 12 and. 0.8x 10-12 moles XDH per minute per gram of liver for the 8 day chick, 1 day chick and 14 day embryo respectively. The t l/2 values for the 8 day chick, 1 day chick and 14 day embryo are 17, [infinity], and [infinity] hours respectively. When L-valine- 14 C(u) is used as substrate, the rate constant for synthesis is 7. 0 x 10-12 moles XDH per minute per gram of liver for the 1 day chick. The rate of synthesis of XDH relative to the rate of synthesis of total soluble protein for the 1 day chick is 1. 7 for valine as substrate and. 0. 9 for argiriine. The role of synthesis and degradation in determining enzyme concentrations is discussed. Also included. is a critique of the methodology. Advisors/Committee Members: Newburgh, Robert W. (advisor).

▼ The major source of calcium for the developing chick embryo is the eggshell. However, the actual mechanism of calcium solubilization from the shell is unknown. The temporal correlation of carbonic anhydrase activity to calcium movement implies that an acidic environment is essentail. To clarify the role of carbonic anhydrase in calcium solubilization and uptake by the chorioallantoic membrane of the chick embryo treatment effects on embryo development, carbonic anhydrase activity and calcium and pH levels were investigated. The treatments consisted of solutions of acid, base, calcium and strontium chlorides, and the enzyme inhibitor-acetazolamide.Experimental sampling was conducted from eleven to sixteen days of incubation. The treatments were administered daily by dipping the eggs into a treatment solution with subsguent sampling on the following day. The acid treatment solution produced a significant (P≤0.05) increase in calcium solubilization and a decrease in carbonic anhydrase activity from the control levels. The base treatment solution produced a significant decrease in calcium solubilization and an increase in carbonic anhydrase activity from the control levels. The calcium chloride treatment solution (providing a partial source of a calcium non-carbonate compound) and the strontium chloride treatment solution (providing a partial source of a non-calcium non-carbonate compound) showed no overall effect on embryonic calcium concentrations. However, there was a decrease in carbonic anhydrase activity from that of the control. This decrease did not appear to be due to a calcium mediated process but was more sensitive to changes in bicarbonate or carbonate levels. Treatments with acetazolamide demonstrated that there was a decrease in carbonic anhydrase activity and also a decrease in calcium transported. However, when an acid treatment was combined with the acetazolamide treatment, calcium was transported even though carbonic anhydrase activity was greatly suppressed. These results confirm that carbonic anhydrase activity appears to be fimctioriing in calcium solubilization and maintenance of the embryonic acid-base balance. It does not appear that the enzyme functions primarily in the transport of calcium across the chorioallantoic membrane.
