Abstract:
The use of fermented products from probiotic microbes as supplement feed is expected to stimulate the growth and biocontrol of pathogenic bacteria in ducks with high feed efficiency. Feed biotechnology products based on tofu waste fermented with yeast culture (TWF) contain high levels of protein and the amino acid lysine, and contain probiotic microbes (107cfu/g). This research aims to examine the effect of fermenting tofu waste with yeast culture on the quality of tofu waste as a feed ingredient and the performance of ducks. The fermented product was tested on 240 male Bali ducks aged 2 weeks in a completely randomized design with four treatments and six replications. Each replication used 60 male Balinese ducks with homogeneous body weight. The four treatments were ducks given rations without TWF supplements as control (TWF0); diet supplemented with 2% TWF (TWF1); diet fed 4% TWF (TWF2); and rations given 6% TWF (TWF3). The results showed that supplementation of 4-6 TWF in feed significantly (P<0.05) increased body weight gain and feed efficiency.It can be concluded that the growth performance and feed efficiency of ducks increased significantly with the supplement of tofu waste fermented by yeast culture.
