Abstract

This experiment was conducted to compare, two methods of early FEED RESTRICTION on the GROWTH, PERFORMANCE and CARCASS CHARACTERISTICS of BROILERs. Two hundreds and sixty one-day-old BROILERs (Lohman) were assigned to five treatments with four replicates in a completely randomized design. Chicks were full-fed from 7 to 13 d or given 25% and 50% of ad libitum intake on a daily basis, or 100% of ad libitum intake on a daily basis, when the diets were diluted 25% and 50% with rice hulls. The body weight, feed intake and feed conversion ratio were determined weekly and CARCASS CHARACTERISTICS were measured at 49 d of age. FEED RESTRICTION depressed significantly (P<0.05) the body weight gain and feed conversion in restriction period. The chicks were able to fully recover body weight depression by 49 d. The method and severity of restriction had no effects on body weight, feed intake, daily gain and feed conversion at 13 to 49 d. The 50% qualitative feed restricted birds showed significantly (P<0.05) lower abdominal fat pad in comparison with the full-fed birds. The mortality rate was not affected by treatments. The results of this experiment showed with early FEED RESTRICTION especially quantitative FEED RESTRICTION at level of 25% we can get similar body weight between restricted and full-fed BROILERs at 49 days of age.
