This experiment was conducted to compare the effects of prebiotic as alternative feed additive to an antibiotic growth promoter (bacitracin methylene disalicyate) on the growth performance and morphometrical parameters of the small intestine of broiler chickens. One hundred and forty four day old broiler chicks were randomly assigned to one of three dietary treatments for 6 wk and each treatmen...

Phytogenic feed additives are used as antibacterial, anti-inflammatory and performance enhancer in the nutrition of broiler chicks. In present study, it was aimed to investigate effects usage phytogenic which an alternative antibiotics broilers at different levels rations, on morphology duodenum ileum. For this purpose, 48 male ROSS-308 one-day-old chicks were study. Chicks with a body weight 4...

The aim of the present study was to compare the efficacy of commercial herbal products on performance and immune response of broiler. One hundred twenty chicks were randomly divided into 12 experimental units (replicates) having ten chicks each. These experimental units were allotted to four treatment groups (T1, T2, T3 and T4) such that each treatment has three replicates. Group T1 was without...

this experiment was conducted to evaluate of different levels of water nitrate on performance and blood parameter of broiler chicks. 240 day old ross 308 were assigned in 5 treatments, 4 replicates and 12 chicks per replicate in a completely randomized design. treatments so that water nitrate concentration was 10 mg in drinking water of poultry farm (control group or cg) and another treatment 4...

an experiment was conducted to assess the influences of different growth promoters on performance, carcass characteristic and intestinal microflora of broiler. day-old broiler chicks from arian strain (384) were used in the completely randomized experimental design during 7-42 days of age. eight rations were formulated as a follow 1: control (without growth promoters); 2-control + formic acid (...

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...

this experiment was conducted in order to determine the effects of different dietary growth promoters on growth performance and nutrient digestibility in male broiler chickens. a total of 360 male broiler chicks (day-old ross 308 strain) were distributed into a completely randomized design (crd) having 6 dietary treatments with four replicates and 15 birds in each replicate. experimental treatm...
