The present study was conducted to examine the effects of L-carnitine on pulmonary hypertensive response in broiler chickens reared at high altitude and exposed to hypobaric hypoxia. A total of 192 day-old male broilers (Cobb 500) were randomly assigned to 4 treatments and 4 replicates of 12 chicks. A basal diet composed of mainly corn and soybean meal was formulated and served as a control. Th...

The present study was undertaken to investigate whether dietary lycopene (LP) could prevent the copper-mediated oxidation of low density lipoprotein (LDL), and affect growth performance, relative organ weights, plasma and meat lipid profiles, and LP contents in plasma and tissues in broiler chickens. A total of 160 day-old male broiler chicks were randomly allotted into 16 pens with rice husk a...

The present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to Newcastle disease virus vaccination and bone mineralization. The experiment was conducted using 300 Ross 308 male broilers. One-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

Background & aim: The fruit of Citrullus colocynthis has a bitter taste and antibacterial properties against pathogen factors.The aim of current research was to study the effects of different dietary level of bitter cucumber fruit powderwith and without protexin probiotic supplementation on growth performance, carcass traits and intestinal morphology of broiler chicks....

the effects of phytase and glycosidase supplementation to diets containing rice bran on broiler performance were investigated by using 200 day old (308 ross) broiler chicks in a completely randomized design with five treatments and four replicates. the five dietary treatments were as: corn-soybean meal based diet; diet containing rice bran; diet containing rice bran supplemented with natafous; ...

the effects of wet-feeding of five levels of corn steep liquor (csl) on broilers performance and relative internal organ weights were examined. three hundreds 1-d old broilers (ross 308) were randomly allocated to one of the six dietary treatments in a completely randomized design with 5 replications of 10 chicks per pen. the dietary treatments were: 1. dry-fed control, no add water nor csl in ...

this experiment was conducted to evaluate the effects of different levels of artemisia sieberi oil (zero, 100, 200 and 300 mg/kg) and antibiotic on performance and blood parameters in broiler chicken. 200 day-old broiler chickens (ross 308) were allocated to five treatments, four replications with a completely randomized design. in total period, broilers were fed dietary artemisia sieberi oil a...

the present study was carried out to examine the effect of supplemental dietary valine in the starter diet of broilers (0-15 d of age) on performance, antibodyresponse to newcastle disease virus vaccination and bone mineralization. the experiment was conducted using 300 ross 308 male broilers. one-day-old chicks were randomly allotted to 3 groups; each group consisted of 5 replicate pens with 2...

This study was conducted to investigate the effects of dietary supplementation with multiple enzymes composed of phytase plus carbohydrolases (ROVABIO Max, RM) on growth performance, nutritional availability and intestinal viscosity in broiler chicks. A total of one thousand, one-day-old male broiler chicks were randomly allotted into treatment groups that received one of five experimental diet...

background: heat stress declines the performance through physiologic changes of the poultry. objectives: this experiment was conducted to evaluate the effects of different levels of l-carnitine on performance, carcass characteristics and some blood parameters of broiler chickens fed with high fat diets under heat stress. methods: two hundred one-day-old broiler chicks (ross 308) were used in a ...
