A total of 96 one day-old Ross 308 chickens, divided, in to 12 groups (3 treatment and 4 replicate pens per treatment and 8 chickens per pens) in a same environmental conditions. Group A, consider as control group and group B and C considers as experimental groups. From first day, vitamin A premix was added to group B diets and complex of vitamin E premix and selenium was added to group C diets...

This study was performed to investigate the effect of dietary aspirin (A) on some performance traits in broilers using a completely randomized design, 120 one-day-old male broiler chicks Ross 308, three levels (0, 50, and 100 mg/kg), 4 replicates, each including 10 chicks, during 42 days. The effects different aspirin, added basal diet, performance, carcass characteristics, digestive organs wer...

The aim of the current study was to investigate morphological and histological effects Bisphenol A on chicken Ross 308 during embryonic development total 150 eggs were randomly divided into five groups: negative control, positive control injected with con oil treatment groups administered different concentrations (0.005, 0.02 0.1 microliters/egg). second day incubation evaluation conducted days...

This research was conducted to measure the exterior characteristics in four hybrids of broilers fed pelleted and commercial mash feed. A total 112 one-day-old chicks from broiler hybrids, namely, Arbor Acre, Cobb 500, Marshall, Ross 308 were used for this experimentation allocated into treatments with 28 birds each hybrid replicated times 7 per replicate a 2 × 4 factorial experiment. Pelleted m...

this study was conducted to investigate the effect of0 (control), 0.5, 1, 1.5 and 2 ml/l of shirazi thyme aqueous extract in drinking water on performance and immune response in broilers. two hundred one- day- old broiler chicks (ross 308) were allocated to five treatments with four replicates and 10 birds per cage in a completely randomized design. daily feed intake, daily body weight gain and...

Day-old Ross 308 chicks were used to evaluate the effect of dietary gelatin on intestinal development and broiler chick performance. Chicks were randomly allocated to two dietary treatments. The first treatment was the control SB diet based on corn-soybean meal and second treatment was the SBG test diet that contained 2% added gelatin with the total sulfur amino acid level remaining the same as...

This study was conducted to investigate the effects of protexin probiotic and aquablend avian antibody on the performance and immune system of broilers. In this experiment, 320 1-day-old male broiler chicks of the Ross 308, with 5 treatments and 4 replications in a completely randomized design were distributed in experimental units (cages). The treatments include: control (C), protexin (P1), pr...

An experiment was conducted to assess how hatchability performance of eggs is affected by line and age female broiler breeders. Response variables analyzed were hatchability, infertility, pipping (i.e., pipped shell but not emerged), embryonic mortality (1st, 2nd, 3rd wk), malposition. The trials involved a total 2,880 fertile from two breeder lines (Ross 308 Cobb 500) at different ages (30 50 ...
