Effects of yeast culture on rumen fermentation, digestibility and duodenal flow in dairy cows fed a silage based diet


, : Effects of yeast culture on rumen fermentation, digestibility and duodenal flow in dairy cows fed a silage based diet. Livestock Production Science 32(3): 219-229

Four Friesian cows, fitted with rumen cannulae and T-shaped duodenal cannulae, wer fed grass silage: concentrates (50:50, dry matter (DM)) and used in a cross-over design to study the effects of a yeast culture (YC) from Sacharomyces cerevisiae (10 g/day) on rumen fermentation, digestibility and duodenal flow of nutrients. Rumen pH, ammonia and voltile fatty acid concentrations as well as molar proportions of acetate, propionate, butyrate and valerate were not affected by the inclusion of YC (P lt 0.05). However, the proportions of isoacids were significantly decreased (P lt 0.01). YC did neither affect the total tract nor the rumen digestibilities of organic matter, neutral-detergent fibre (NDF), acid-detergent fibre and cellulose. However, YC tended to increase the in situ degradation rate of hay DM (P lt 0.13) and hay NDF (P lt 0.010) incubated in nylon bags. The inclusion of YC had no significant effect (P gt 0.05) on the duodenal flow of non-ammonia nitrogen and microbial N. Nevertheless, undegraded feed N in duodenal digesta was significantly (P lt 0.05) increased when YC was supplemented. Changes in rumen outflow are are discussed as a possible reason for lowering protein degradation.
