【 摘 要 】

Supplementation both energy and protein of goats can support optimal microbial growth so that utilization of fibrous feed can be optimized. The aim of this research is to observe the effect of goats which fed complete feed containing 10% cocoa pulp and various fiber sources toward estimation of microbial protein supply (MPS) and efficiency of microbial protein supply (EMPS). Twelve local male goats, aged 1-1.5 years old, were randomly assigned to one of four treatments according to completely randomized block design consisted of 3 treatments and 4 blocks as replications. The treatments were P1: Complete feed containing 50% rice straw, P2: Complete feed containing 50% corn cobs and P3: Complete feed containing 50% soybean straw. The results showed the estimated of MPS was P1 = 16.25 g/d P2 = 14.05 g/d, and P3 = 24.57 g/d, respectively. The EMPS per kg organic matter fermented in rumen was P1 = 86.5 g/kg BOFR, P2 = 73.0 g/kg BOFR, and P3 = 150.25 g/kg BOFR. Analysis of variances indicated that treatment did not affect (P>0.05) MPS and EMPS. In conclusion, based on estimated MPS and EMPS, the three types of fiber could be used as the main fiber sources in formulating complete feed containing cocoa pulp for local goats.
