two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...
متن کاملThe influence of the season and market class of broiler chickens on breast meat quality traits.
The influence of the season and market class of broiler chickens on breast meat quality traits was determined on a total of 18 flocks reared and processed under commercial conditions. According to the Italian poultry production system the following classes of birds were considered: light size (1.2 kg of carcass weight; n = 90) and medium size (1.8 kg of carcass weight; n = 90), represented by f...
