in this research the effect of feeding wheat/ barley based diets supplemented with three commercial enzymes containing xylanase and ?-glucanase activities and including matrix value their on performance and gastrointestinal tract size of broiler chicks was investigated. a total of 260-day-old male broiler chicks (ross 308) were allocated to 5 treatment groups, with 4 replicates per treatment an...

the effect of dose and regimen of organic acids on micro-flora and morphology of small intestine were studied in a total of 300 male day old broiler chicks using completely randomized design. salkil had no significant effects on the number of villi per view field and percent of convoluted villi. salkil had a significant effect on the number of tongue, ridge shaped (p

The objectives of this study were to determine whether intestinal viscosity caused by mixed linked barley beta-glucan depresses ileal nutrient digestibility and digestive enzyme activities and to determine the interaction of intestinal viscosity, digestive enzyme activities and ileal nutrient digestibility in different ages of poultry. In Experiments 1 and 2, 1-d-old broiler chicks and 1-y-old ...

A total of 210 twenty twoday-old broiler chicks were used in this programme to investigale the performance, [ca\ intake, digestibility and visceral organ mass of broiler chicks fed with high level of olive pulp.supplemented with two antibiotics: streptomycin and tylosin. The two antibiotics were added to supply 150 nig/kg of the active ingredient. Chicks which consumed the medicated diets had m...

This study was conducted to investigate the effects of different levels of dried whey and protexin probiotic on the productive performance, carcass trait and blood parameters of broiler chickens. In this study, 360, one-day old male and female commercial Ross 308 broiler chickens of mixed gender were used in a randomized design with four treatment (six replicated in each treatment and 15 birds/...

The tilapia industry has grown significantly. Much waste is generated by the industry due to the fact that only the myomere muscles are removed and sold for human consumption. This portion constitutes approximately 36% of the entire fish, leaving 64% of the fish as waste lost during the various processing operations. This waste from the tilapia processing plant has the potential of being an alt...

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...

ABSRACT The present experiment was designed to evaluate the effect of different protein and energy levels on broilers performance under hot climatic conditions. A total of three hundred Ross-308 chicks were selected on basis of uniform starting live bodyweight (45g/chick) proximately. Chicks were randomly divided into three treatments with five groups of 20 chicks per pen. Diets were formulated...

The effects of dietary vitamin E levels on mucosal maltase and alkaline phosphatase (ALP) enzyme activities and on the amount of mucosal malonyldialdehyde (MDA) in broiler chickens were studied in the present study. One hundred and eighty of male day old broiler chicks (Ross 308 strain) were randomly assigned into five groups, each with three replicates and 12 chicks in each replicate. Chickens...
