The yield of carcass parts as well as levels of carcass fat, moisture, and ash were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) and in the Ross 308 commercial broiler, when fed diets that were representative of those being fed during 1957 and 2001. The Ross 308 was used to represent 2001 commercial broilers. Comparisons of carcass weights of the Ross 308 on the 2001 diet ver...

A progressive selection for broiler live and processing performance traits has changed broiler growth patterns during the post hatch period. However, limited information is available to understand whether changes have also occurred during the embryonic stages. This study aims to examine influences of broiler strain on nutrient availability, embryonic development, and nutrient metabolism during ...

Immunocompetence of the 2001 Ross 308 broiler strain and the 1957 Athens Canadian Randombred Control (ACRBC) strain was compared when they were given diets representative of those that were being used in 1957 and 2001. Antibody response against SRBC, in vivo lymphoproliferation against Phytohemagglutinin-P (PHA-P), and inflammatory and phagocytic responses of the macrophages were measured. The ...

Studies delineating the dietary Val needs of modern commercial broilers are sparse. Three studies were conducted to determine the dietary Val nutrient needs of Ross x Ross 308 male broilers. Three time periods were evaluated independently, 0 to 14 d (starter), 14 to 28 d (grower), and 28 to 42 d (finisher) of age. Corn- and peanut meal-based diets for each feeding phase served to titrate the Va...

Body weight, feed consumption, and mortality were measured in the 1957 Athens-Canadian Randombred Control (ACRBC) strain and in the 2001 Ross 308 strain of broilers when fed representative 1957 and 2001 diets. The dietary regimens were chosen to be representative of those used in the industry in 1957 vs. 2001. The 1957 diets were fed as mash, the 2001 starter was as crumbles, and the grower and...

this experiment was conducted to evaluate the effects of different commercial multi enzymes and nutrients levels of diets on performance and carcass traits of broilers. in this experiment 288 day old ross – 308 broilers (male and female) were used as (2*4) factors include: two levels of nutrients in diets (ross- 308 nutrients recommendation and 5% less than ross- 308 nutrients recommendation) a...
