| Abstract | ||
| The present study aimed at comparing the influence of dietary supplementation of live dried yeast Saccharomyces cerevisiae and chitosan on rumen fermentation and rumen development in male Balady goats. A total number of 12 castrated adult male Balady goats (bucks) aged one year old were allocated into three similar groups (4 males each). Concentrates were offered at rate of 3% of body weight. Experimental groups were control group fed on basal diet consists of concentrate mixture without any feed additives; S. cerevisiae group fed on basal diet with feed additive of S. cerevisiae at rate of 0.3% (3Kg/ ton concentrate); chitosan group fed on basal diet with feed additive of chitosan at rate of 0.2% (2kg/ ton concentrate). The obtained results showed a significant (p<0.05) increase in total volatile fatty acids concentrations (TVFA), total ruminal protozoal count (TPC), quantative morphmetrical analysis of ruminal papillae length, width and number of papillae / surface area (cm2) and significant (p<0.05) decrease ruminal ammonia nitrogen concentration in Saccharomyces group when compared with the control group. While, treated with S. cerevisiae or chitosan caused no significant variation (p>0.05) | ||
