Abstract
This research was conducted to find out the effect of probiotic bacteria Bacillus amyloliquefaciens as proteolytic bacteria and jengkol bark extract (Archidendron jiringa) on the productivity of male magelang ducks. The treatments in this study were given through water. The treatments in this study were: P0 = Water (without the addition of probiotics and jengkol bark extract- P1 = Water with the addition of 0.5% probiotics + 0.05% jengkol peel extract- P2 = Water with the addition of 1% probiotics + 0.1% jengkol peel extract- P3 = Water with the addition of 1.5% probiotics + 0.15 jengkol peel extract- P4 = Water with the addition of 2% probiotic + 0.2% jengkol peel extract. Data obtained were analyzed by ANOVA and continued by Duncan^s Multiple Range Test if the results were different. The results showed that the administration of Bacillus amyloliquefaciens and jengkol bark extract had no significant effect on feed intake, water intake, daily weight gain, body weight, and feed convertion of male magelang ducks. It is concluded that administration of probiotics Bacillus amyloliquefaciens did not improve the performance of male magelang ducks. Further research is needed on the effectiveness of probiotic bacteria in the instestinal of male magelang ducks
