Abstract
Five crossbred goats with average liveweight 25 ±1.0 kg were randomly assigned according to a 5x5 Latin square design to receive five concentrate diets at 2% BW, containing 0, 25, 50, 75, and 100% YFPKC, respectively. Plicatulum hay was offered on ad libitum basis. Based on this experiment, there were no significant differences (P>0.05) among treatments regarding DM intake, whereas apparent digestibilities of DM, CP, NDF and ADF were affected (P<0.05) by inclusion of YFPKC in diets and tended to be slightly lower for goats fed the diet T5 containing 100% YFPKC as compared with other treatments. The ruminal pH, NH3-N and volatile fatty acids were similar among treatments (P>0.05). It could be concluded that the optimal level of YFPKC in concentrate replacement of SBM should be 25-75 or 5-15% in concentrate diet for goats.
