ABSTRACT: This study was carried out to assess the effect of some feed additives on quality of broiler carcasses. A total of one hundred and eighty of one day old broiler chicks were reared and divided into six groups. Five groups were fed on treated rations (20 g of freshly minced of each of garlic and onion to 1 Kg of ration, 400mg of vitamin E in one liter of drinking water, B.subtilis 4 ×10⁸ c.f.u was added in amount 1.5 g to 1 Kg ration, 10 g hot pepper to one Kg of ration and 50g zinc bacitracin added to the ration in amount 1.5 g to 1 Kg ration), and the sixth group used as control group. Broilers were slaughtered at age of 45 days to evaluate pH, moisture content, cooking loss, shear force and instrumental color. The feed additives (onion and garlic, Vit.E, hot pepper, B.subtilis and zinc bacitracin) were decreased pH in broiler meat. Moisture did not influence by dietary supplementation. Cooking loss was decreased with storage of broiler meat. Vit.E, B.subtilis and hot Pepper groups increased tenderness in broiler meat. Onion and garlic and Vit.E increased lightness and yellowness of broiler meat. Zinc bacitracin and hot pepper decreased redness of broiler meat.
Keywords: Feed additives, onion & garlic, vitamin E, hot pepper, B.subtilis, zinc bacitracin, meat quality and Broiler carcasses.

ABSTRACT: Burning of agricultural residues especially paddy straw is now recognized as a major source of environmental concern in India. Burning of huge quantities of paddy straw annually leads to emission of obnoxious gases thus causing adverse impacts on, health of human, animal and bird population. This practice can be discouraged through its utilization as an alternate litter material to commonly used paddy husk which is now available at costly prices because of its use in different industries thus raising the cost of broiler production. This was evaluated through the experiment during winter season conducted on broiler chicks. Broiler chicks (n=144) were distributed into three treatment groups, each having 4 replicates of 12 chicks with equal sex and ratio and average group weight, and reared up to 42 days of age under similar conditions of housing and management except the variation in litter material. Paddy husk (PH), unchopped paddy straw (UPS) and chopped paddy straw (CPS) were used as different litter materials. The growth parameters tested in the experiment were body weight, weight gain, FCR, PER, EER and carcass characteristics (viz. evisceration rate and proportion of cut-up parts). The litter type had no significant effect on body weight, weight gain, FCR, PER and EER among all the treatments. The average body weight at 42 days of age was 1939, 1947 and 1960 g, respectively in PH, CPS, UCPS groups. The bedding type had no significant effect and no influence on the carcass characteristics viz. evisceration rate and proportion of cut-up parts of the carcass, so it was concluded that paddy straw can be used as good bedding material for broiler chicks.

ABSTRACT: A study was conducted from October 2009 and March 2010 with the objective of determining the prevalence of poultry coccidiosis and identifying the species of Eimeria at Kombolcha poultry farm. A total of 638 dead White leghorn chickens of age 1 to 60 days were examined on post mortem, mucosal scraping examination, examination of gross and histopathological changes, and identification of Eimeria species. Prevalence rate of 22.3% (142/638) was assessed. A statistically significant difference p < 0.05 (χ² = 261.995, p = 0.000) was noted among the studied age groups with maximum prevalence at 41-50 days of age. Five Eimeria species were identified, namely: E. tenella (37.86 %), E. brunette (29.22 %), E. necatrix (12.35 %), E. acervulina (15.22 %), and E. maxima (5.35 %) which were identified for the first time in the farm. In conclusion, coccidiosis remained still a major problem in the farm by changing its mode of occurrence from time to time as to the variations of the management system. Further strategies needs to be implemented to reduce the loss due to coccidiosis.

ABSTRACT: In isoenergetic - isonitrogenous diets, barley at levels of 0, 25, 50, 75 and 100 % was substituted for corn and its effects on broiler chicken performance was studied. This study was carried out with 5 levels of barley (0, 25, 50, 75 and 100 %), 3 replicates and 14 birds in each replicate in a completely randomized design. In this experiment 300 day old broiler chicks (Lohman) were used for 42 days. The results showed that barley up to 25% substitution had no adverse effect on broiler performance. It is concluded that in diet supplementation with barley until 25% could done without any adverse effects on performance, although enzyme supplementation should be considered in the ration to decrease NSP in the barley.
