Abstract

This study aims to determine effect of sex on ruminal fermentation characteristics and enzyme activities in Garut sheep. Twelve Garut sheep (6 females and 6 males) were used. The sheep were about twelve months old with an average initial body weight of 25±2 kg, and were divided into two groups according to sex. The sheep were housed individually, and were allowed for free access to fresh clean water. Animals were fed separate feeding of concentrate (bran pollard) and roughage (king grass) with ratio of feed 40:60 dry matter basis. The feed contained CP 12.10% and TDN 64.31%. At the end of the study, rumen contents were sampled to measured pH, microbial protein content, VFA, ammonia concentration, protozoa, and enzyme activities. There was no significant difference (P>0.05) among sheep in ruminal pH, microbial protein, ammonia, protozoa, and propionic acid, but there were significant differences in acetic and butyric acid, total FVA, CMC-ase, and protease activities in rumen fluid (P<0.05) between females and males. The females had lower acetic, butyric acid and total FVA (P<0.05), as well as amylase activities (P<0.01) than the males. It could be concluded that males Garut sheep had more efficient ruminal fermentation of feed than the females.
