4.3. Growth Performance
The higher average daily BW gain of the goats, including the pre-weaning kids, in the soya waste groups during Exp. 1 and 2 could be attributed to the higher CP of the soya waste compared to that of the pelleted compound feed and Napier grass (Feng et al., 2007, Kim et al., 2012 and Rahman et al., 2014a). This finding confirms the nutritive potential of soya waste as regards growth. The DM and nutrient digestibility also increased significantly in accordance with increased dietary soya waste (P < 0.05) ( Table 2). The increase is one factor explaining the greater BW in the dietary soya waste group. Harjanti et al. (2012) reported that commercial pelleted compound feed could be replaced with soya bean curd residue silage and that it did not affect ruminal fermentation. Furthermore, it ensured a positive N balance in ewes ( Harjanti et al., 2012).
