Abstract

This experiment aimed to compare the rumen microbial nitrogen supply in male and female Garut Sheep. Six male and female Garut sheep were put in the metabolism cages, fed ad libitum with Pennisetum purpureum and bran pollard with a ratio 60: 40. This study begins with an adaptation period of 14 days. Urine collection was carried out for seven days. Urine samples be measured for purine derivatives (PD), consisting of allantoin, uric acid,and xanthine-hypoxanthine. During the collection period, samples of feed, uneaten feed, and feces were taken out for dry matter and organic matter analysis. The total urinary PD excretions data were used to estimate microbial nitrogen supply (EMNS) based on the equation postulated with modification in endogenous PD excretion for male and female Garut sheeps. Data obtained were analyzed using the Independent Student T-Test design. The results showed that urinary PD excretion in male Garut sheep was higher than in females (0.160 vs 0.127 mmol/W0.75/day). EMNS in male Garut sheep also tended to be higher than in females (1.14 vs 0.74 g N/day). In conclusion, the excretion of PD and EMNS in male Garut sheep tended to be higher than in females.
