Performance Enhancement in Male Bayang Ducks after Oral Administration of the Probiotic Bacillus subtilis FNCC 0059

Abstract

Ducks have a strategic position in Indonesian society, apart from providing quality feed, ducks also offer excellent opportunities to village communities to earn income. However, the high feed conversion of duck is an obstacle in the intensive development of duck farming because 70% of poultry production costs come from feed costs. The purpose of this study was to investigate the effect of Bacillus subtilis FNCC 0059 administration as a probiotic on growing male Bayang duck performance. A randomized design was used in this study. The probiotic Bacillus subtilis FNCC 0059 was included in drinking water of male Bayang ducks at different doses (0, 76x10 6 , 69x10 8 , 65x10 10 , 53x10 12 CFU/ml), and each of these five treatment was replicated four times. Feed intake, body weight gain, feed conversion, and final body weight were the parameters studied. The results revealed that the probiotic Bacillus subtilis FNCC 0059 has a significant (p<0.05) effect on feed intake (being low in 53x10 12 and 65x10 10 CFU/ml), body weight, body weight gain (being high in 69x10 8 , 65x10 10 and 53x10 12 CFU/ml) and feed conversion (being low in 53x10 12 and 65x10 10 CFU/ml) of male Bayang ducks. In conclusion, the administration of probiotic Bacillus subtilis FNCC 0059 in drinking water to male Bayang ducks at a dose of 65x10 10 CFU/ml can improve the performance and feed efficiency of male Bayang ducks.
