ABSTRACT This study aimed to evaluate the development of the gastrointestinal tract and organs in 18-days embryos (ED18) and newly hatched chicks from broiler breeders supplemented with conjugated linoleic acid (CLA), as well as the development of their progeny up to 7 days of age, which also received CLA supplementation in the pre-placement diet during the first 12 hours post-hatch. A total of 540 eggs from two Cobb500 breeder flocks, supplemented with either 0 or 0.025% CLA, were incubated, and […]
