The Effect of Fermented Soybean Meal on The Growth Performance of Kampong Chickens

Abstract

Abstract The present study evaluated the effect of dietary soybean meal (SBM) fermented with Bacillus subtilis and Aspergillus niger on the performance of kampong chickens measured at eight weeks. Ninety birds at 21 d (210±3.69 gram) were used for the experiment. The birds were randomly separated into three treatment groups consisting of six replicates, with five birds per replicate. The treatments were without steam conditioning and fermentation (P0), where the two other groups were fermented with Bacillus subtilis (P1) and Aspergillus niger (P2). Basal diets were based on corn-soybean with crude protein (CP) of 16% and metabolism energy (ME) of 2800 Kcal. The result showed that dietary SBM fermented with Bacillus subtilis and Aspergillus niger increased average daily gain (ADG), final body weight (BW), and decreased feed conversion when compared to control (P<0.05). In conclusion, the present study suggested that replacing SBM with fermented soybean meal increased performance without negatively affecting the feed intake of kampong chickens.
