Abstract: | The present study was designed to investigate the effi cacy of Bacillus circulans and Bacillus sp. as probiotic during realimentation period on performance of broiler chickens. Three hundred of 7 days-old unsexed broiler chicken of Cobb commercial strain were used in the experiment. The treatments were: control ration was fed ad libitum (P-0), ration with energy restriction at 1.5xBW0.67EM kcal/day without (P-1) and with (P-2) probiotic supplementation during realimentation period, and ration with energy restriction at 2.25xBW0.67EM kcal/day without (P-3) and with (P-4) probiotic supplementation during realimentation period. Feed restriction was applied from 7 to 14 days of age. The experiment was arranged as a completely randomized design with 5 treatments and 6 replications. The results showed that feed intake and body weight gain of chickens submitted to early feed restriction on P-1, P-2, P-3 and P-4 were signifi cantly lower (P<0.05) than that of chicken fed control diet. During realimentation period, body weight gain of chicken given P-1 and P-2 was lower (P<0.05) than those obtained from P-3, P-4 and P-0 from 14 to 28 days of age. Compensatory growth only occur during the 28 to 35 days of age on P-4 and had similar performance with control at age of 42 days. It was concluded that energy restriction 2.25xBW0.67EM kcal/day for 7 days (7 to 14 days of age) with supplementation of probiotic B. circulans and Bacillus sp. (P-4) during realimentation period showed similar compensatory growth and body weight, but production index and feed cost better than control. |
