In the present study, the amnion of turkey and chicken embryos were injected 3 d prior to hatch with different levels of vitamin E (VE). In Experiments 1 and 2, turkey embryos received 10, 20, and 30 IU of VE. In Experiment 3, broiler embryos received 10 IU VE. In all three experiments, sham-injected control embryos (0 IU VE) received 300 microL of saline. In Experiments 1 and 2 (turkey embryos...

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 purpose of this study was to investigate the relationship of maternal breeding values of the weight of day-old chick chicks in a commercial broiler line with egg traits including yolk fatty acids. maternal breeding values of 63 hens of known pedigree were estimated through an animal model, containing direct additive genetic effect, maternal additive genetic effect, maternal common environme...

This study was performed to detect the efficacy of probiotic (PROBAC plus) as anti-stress on behavior and welfare heat-stressed broilers (32-35oc) from age 22d 42d. One-hundred twenty chick were divided into 4 groups. The first group control (basal diet), second reared at high temperature third diet + Probiotic) fourth probiotic). Behavioral patterns recorded week till end experiment. At last d...

Abstract The aim of this study was to predict production indicators and determine their potential economic impact on a poultry integration system using artificial neural networks (ANN) models. Forty zootechnical parameters from broiler breeder farms, one hatchery, flocks, slaughterhouse were selected as variables. ANN models established for four output variables: “saleable hatching”, “weight at...

The role of histamine in the regulation of food and water intake in mammals and birds of the review, this study evaluated the effects of intraperitoneal administration of chlorpheniramine as histamine H1-receptor antagonist, in broiler chicks on feed intake and satiety in water and was hungry. 32 male Ross broiler chicks reared in groups of four weeks, 16 samples (control and test) were then in...
