The objective of this study was to evaluate the effect of varying levels of coconut meal (CCM), replacing soybean meal, on feed intake, digestibility and rumen fermentation of goats fed corn silage. Eight growing Thai native Anglo-Nubian goats between 8 to 10 months of age and pre-trial average body weight of 17.71.9 kg were allotted into two groups on the basis of body weight in a randomized double 4*4 Latin square design. The four treatments were levels (%) of replacement of soybean meal by CCM of 0 (control), 25 (CCM25), 50 (CCM50) and 75 (CCM75) in a concentrate give as a supplement to corn silage. There were no consistent effects of CCM level on feed intake and DM, OM and CP digestibility but NDF digestibility was negatively related with CCM level (R2=0.94). At the 75% substitution level of soybean by CCM, performance was reduced as measured by estimated rate of rumen microbial synthesis and live weight change.
