A Symbiotic Improves Performance and Carcass Yield of Broilers
In order to evaluate the effects of a symbiotic on 1–42-d-old broiler chicks, performance and carcass yield (CY), as well as litter concentrations of phosphorus and nitrogen were measured in a trial using 640 male chicks (Cobb 500). Birds were randomly distributed into 4 treatments with 8... Continue reading...

Responses of broiler chickens to Eimeria challenge when fed a nucleotide-rich yeast extract
Nucleotide-rich yeast extract (YN) was investigated for effects on growth performance, jejunal physiology, and cecal microbial activity in Eimeria-challenged broiler chickens. A total of 360-day-old male chicks (Ross × Ross 708) were placed on floor pens and provided a corn–soybean meal-based diet... Continue reading...
