Effects of replacement soybean meal with fermented cassava pulp by Saccharomyces cerevisiae in DIETS on Rumen fermentation in growing goats

The aim of this study was to determine the effect of replacing soybean meal (SBM) with fermented cassava pulp by Saccharomyces cerevisiae (FCSC) in the diet of growing goats. Growing goats were randomly assigned to five dietary treatments according to replicated 5 × 5 Latin square design. Dietary treatments were five levels of replacement SBM to FCSC at 0, 25, 50, 75, and 100% of crude protein in concentrates. The results showed that total dry matter intake (DMI, g/day) was increased (P < 0.05) with increasing FCSC. The highest for body weight change was found in 75% replacement of SBM by FCSC. The results suggested that FCSC could replace up to 75% of SBM in concentrate of growing goats fed rice straw as roughage. Based on this result, using 75% FCSC as the main source of protein to completely replace soybean meal was beneficial to growing goats in terms of feed intake and productive performance.
