the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. in this experiment, 192 day old female ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 replications. dieta...

this study was carried out to investigate the effects of dietary putrescine (put) on broiler’s response fed low crude protein (cp) diets. a total of 192 male day old chicks were fed with four dietary treatments including two levels of put (0 and 0.03%) and two levels of cp (normal and low) with factorial combinations. weekly growth performance, nutrient digestibility and intestinal morphology (...

the objective of the present study was to determine the effects of different levels of l-arginine in the diet on the growth performance, carcass traits, and blood parameters of female ross broiler chickens within their starter period. a number of, 192 day old female ross broiler chickens were fed with 4 dietary treatments in a completely randomized design, each dietary treatment had 4 replicati...

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...

Two experiments were conducted to evaluate the effects of fusaric acid (FA) in broiler chicks (Exp. 1) and turkey poults (Exp. 2). In each experiment, 100 day-old birds were allotted randomly to dietary treatments containing 0, 100, 200, 300, or 400 mg FA/kg of feed. Each dietary treatment was fed to 4 pen replicates of 5 birds each for 21 days. Fusaric acid had no effect (P > 0.05) on feed int...

a total of 700 day old female broiler chicks (ross 308) were distributed into seven groupsin acompletely randomized designwith five replicates, and 20 chicks in each replicate. dietary treatments, timeof the switch from an unsaturated sunflower oil (sfo) to a saturated tallow (t)dietary fat source, were: 1) sfo for the entire growth period (6 weeks), 2) sfo for 5 weeks followed byt for last wee...

the objective of the present study was to determine the effects of feeding high levels of l-arginine on growth performance, blood metabolites, and carcass meat quality of female ross broiler chickens at the starter period. in this experiment, 192 day old chicks were fed with 4 dietary treatments (100%, 153%, 168% and 183% of digestible arginine, based on the ross catalogue recommendation) with ...
