Abstract

Rumen Microbial ecosystem mainly consists of bacteria, PROTOZOA and fungi population and their main function in the rumen is fermenting consumed feedstuff. The objective of this experiment was determining the effect of complete elimination of PROTOZOA, on rumen microbial protein supply. In this experiment four rumen fistulae and castrated male SHEEP and four rumen fistulae GOATs were used in a Latin square design. Four diets consist of: 1) all forage diet, 2) diet with 20% concentrate, 3) diet with 40% concentrate and 4) diet with 60% concentrate, performed in faunated and defaunated stages, respectively. Defaunating the rumen of SHEEP and GOAT was performed by two stage procedure of emptying and washing method. Determination of rumen microbial supply was calculated by measuring daily PURINE DERIVATIVES excreted via urine. This method is based on measurement of total uric acid, allantoine, xanthine and hypoxanthine excreted from urine. The results of this survey indicated that diets had no significant effect on microbial protein (MP) supply in rumen of both SHEEP and GOAT, but defaunation of SHEEP rumen increased MP synthesis (11.18 vs. 7.73 g/day) and elimination of PROTOZOA form GOAT rumen increased MP supply, too (7.82 vs. 6.05 g/day), and there was a significant statistical difference between faunated and defaunated stages (p<0.05).
