Effect of dietary energy density and folic acid supplementation on white striping occurrence and growth performance of broiler chickens

Broilers were allocated to eight treatments consisting of two energy levels: normal (NE) and high (HE), four folic acid (FA) levels (2.2, 5, 10, 15 ppm). On day 42, male female chickens euthanized per pen, white striping (WS) evaluation was performed on the pectoralis major. Birds fed HE diets had reduced (P < 0.05) feed intake conversion rate than those NE diets. With increasing FA levels, there WS score increased breast fillet percentage in but not males. scores higher 0.01) females.
