One-day-old SPF chicks were inoculated with the Cux-l strain of chicken infectious anemia virus (CIAV), and the clinical development of disease and its macroscopic and microscopic alterations in the thymus and bone marrow, were observed. Tissue sections of thymus and bone marrow were stained using the streptavidin-biotin peroxidase method and examined under light microscope for evaluation of an...

1. Tissue-specific profiles of the expression of the antioxidant enzymes superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) and the concentrations of reduced glutathione (GSH) during the development of the chick embryo were investigated. 2. The liver, brain, yolk sac membrane (YSM), kidney, lung, heart and skeletal muscles were collected at the following days of embr...

four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (csos) as a substitute for refined soybean oil (rso) in broiler diet. the experiment was carried out following completely randomized design. the chicks were randomly distributed in three treatment gr...

this study was carried out to evaluate the effect of different levels of anise seed on the performance, immune system, antioxidant activity and blood estrogen level of broiler chicks. a total of 192 day -old ross 308 broilers were trained for 42 days in a completely randomized design with four treatments, four replicates and 12 birds per each replicate. treatments were included the levels of ze...

Study was carried out to find out the effect of L-carnitine supplementation on carcass characteristics in Venncobb broiler chicks fed with diet containing animal fat. Eighty day old commercial broiler chicks were randomly allotted to two treatment groups (T1 and T2) with four replicates of ten chicks each. The birds were fed with standard broiler chicken ration (BIS, 1992) containing 5% animal ...

Day-old chicks from 3 hatcheries were placed on bedding paper and brought to a commercial broiler farm between January and July 2016. Sixty-six samples of the paper, which were stained with meconium droppings of the chicks, were collected and examined for isolation of cephalosporin-resistant Enterobacteriaceae. Cefotaxime (CTX)-resistant Klebsiella pneumoniae (1 isolate) and Enterobacter cloaca...

The focus of the research was to determine how giant floater (Pyganodon grandis) worked as a feed ingredient in broiler production. A total 120 one-day-old Cobbs 500 were reared for 42 days, regardless sex. chicks weighed and brooded 14 days. distributed at random on fourteenth day four treatments with three replications, each containing ten chicks. They given varied proportions meal ingredient...

Present study was carried out at MS poultry farm Baffa, Mansehra during 2006. The main objective of this study was to investigate the effect of different levels of probiotics named as Organic Green Culture on the immune response of broiler chicks, using Newcastle Disease Haemagglutination Inhibation (HI) antibody titer as indicator. For this purpose, 448 Hubbard day-old broiler chicks were rand...

widespread occurrence of h9n2 low pathogenic avian influenza (lpai) viruses in many asian countriesduring the past decade has resulted in the need for evaluation of the pathogenesis of h9n2 virus infection. in this study, tissue tropism and dissemination of a/chicken/iran/772/1998(h9n2) virus throughout the body of broiler chickens were investigated. the clinical signs, gross lesions and antibo...

this experiment was carried out to investigate the effects of in yolk-sac administration of olive oil (0 and 0.7 ml) on productive performance and breast development of broiler chickens exposed to post-hatch fasting stress (0, 12, 24, 36 and 48 hours). a total number of 800, 1-day-old broiler chicks in a completely randomized block design with 10 treatments and 4 replicates were used. live body...
