Biological, Nutritional, and Processing Factors Affecting Breast Meat Quality of Broilers
… and processing factors on breast meat quality of broilers. In the first experiment, the influence of genetic strain, plane of nutrition, and age at slaughter on breast meat quality was evaluated. Breast meat from a high yield line of broilers had lower pH at 24 h postmortem (PM), greater L*, a*, …

Physiological and Biochemical Aspects of Methionine Isomers and Precursors in Broilers
… signaling. To achieve this goal, male Cobb-500 broilers were raised from day of hatch (d0) to d35 post-hatch and fed a diet deficient in methionine and cysteine (Met + Cys) (control) or the same diet supplemented with 0.22% DL-Met, 0.22% L-Met or 0.31% DL-HMTBA (to provide 0.22% DL-Met …

Effects of Yeast Product on Modulating the Adaptive Immune Function in Broilers
… cerevisiae fermentation yeast product was fed to broilers to investigate the effect of yeast products on the broiler immune function. The broilers were vaccinated for Newcastle Disease Virus on day 1 (B1 strain) and day 21 (LaSota strain) via eye drop. Body weights, feed consumption, feed …

Molecular responses of neonatally heat stressed broilers exposed to acute heat stress
Exposure of broiler cockerels to between 35.0 to 37.8 C for 24 hr at 5 days of age increases their survival when exposed to a heat challenge at 6 weeks of age (35.0-37.8 C; RH 50% ). This' phenomenon does not resemble acclimation since the physiological changes known to occur in acclimated birds …

Effect of feeding calcium propionate on carcass composition, and productive performance of male broilers
Male broilers were fed ad libitum a control diet and diets with 1.5% and 2.7% calcium propionate (CaP). Broiler diets were supplemented with CaP for the first 2,4,6, or 8-week intervals. After being fed CaP for the previous mentioned times the broilers received a control diet for the remainder of …
