The Impact of Yeast Culture Residue on the Suppression of Dietary Aflatoxin on the Performance of Broiler Breeder Hens
A study was conducted to examine the effect of yeast culture residue (YCR) on the suppression of aflatoxicosis in broiler breeder hens. One hundred twenty, 35-wk-old, Cobb broiler breeder hens of the same cross were fed diets supplemented with aflatoxin (AF) (0 or 3 mg/kg) and YCR (0 or 2 lb/ton) singly and combined in a 2 × 2 factorial designed experiment. The birds were randomly assigned to p...
متن کاملThe Effect of Broiler Breeder Strain and Parent Flock Age on Hatchability and Fertile Hatchability
The effect of genetic strain (Ross 308; Cobb 500) and parent flock age (Ross at 32 and 36 weeks; Cobb at 26 and 44 weeks of age) on hatchability, fertile hatchability, Egg Weight Loss (EWL) and egg break out analysis were examined. At each flock age, 300 eggs from each treatment group were incubated. Thirty eggs from each treatment group were labeled individually for the measurements of Egg Wei...
متن کاملEffect of dietary zinc oxide and phytase on the plasma metabolites and enzyme activities in aged broiler breeder hens
Background: It has been shown that zinc has an effect on physiological responses in animals and birds. On the other hand, dietary phytase in poultry results in increased availability of zinc. OBJECTIVES: This study was conducted to investigate the effects of zinc oxide (ZnO) and Escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

A 28-week experiment was conducted to study the effects of dietary energy and digestible methionine level on performance and reproductive traits of broiler breeder hens, using 280 Arian broiler breeder hens and 20 males at 26 weeks of age. The experiment was done as 2×2 factorial arrangement in a completely randomized design with 4 treatments and 5 replicates. Dietary treatments were formu...

were: Choretime, Lubing, Plasson, Val, and Ziggety. Higher average maximum temperatures for the SU (32 C) versus the SP (28 C) trial, made the trials significantly different (SD) and therefore were analyzed separately. While no SD were found in BW (kg) during the SP trial, drinker D significantly reduced 42d BW (2.32) in comparison to the A (2.44), B (2.42), C (2.41), and E (2.44) systems. No S...
