A feeding trial was conducted to investigate the effect of skip-a-day feeding program in early growing stage of male broiler chicks on the compensatory growth, and development of visceral organs during the later realimentation period. Day-old 328 male broiler chickens( Avian x Avian) were divided into control(ad libitum feeding) and skip-a-day feeding(limited feeding) treatments. Each treatment was consisted of 4 pens( replicates) of 41 birds each. Chickens on the skip-a-day program were fasted every other day during the second wk of age(8~15 d of age). During the starter period(0~4 wk), chickens were fed a commercial crumble diet. A commercial pellet diet was fed to chickens during the finishing period( 5~8 wk). Chickens were group-weighed every week, and one bird was selected from each pen to measure carcass characteristics. The skip-a-day program delayed the growth rate of male broilers up to 4 wk of age(P<o.05). The difference in BW, however, disappeared from 5 wk of age, indicating that compensatory growth occurred following realimentation. Although not significant, feed efficiency tended to improve by the skip-a-day feeding program However, the skip-a-day program failed to reduce abdominal fat padsize and mortality rate of male broiler chicks in this feeding trial.
