Influence of saccharomyces fermentation and digestion in cerevisiae dose on ruminal sheep fed a corn stover diet

Abstract

A metabolism trial was conducted to evaluate Saccharomyces cerevisiae dose on ruminal fermentation and digestibility. Fourteen Suffolk ewes (35±4 kg BW) with ruminal and duodenal cannula were assigned to a completely randomized design, where treatments were intraruminal dose of microbial culture of Yea- Sacc1026 (0, 1, 3, 5 and 7g/d). Diet was based on corn stover (66.5%), sorghum grain (23.5%), molasses (10.2%) and. urea (1.3%). Ruminal pH, VFA concentration, molar proportion of VFA and. ammonia-N were not affected, by dose. Protozoa population (5.3, 9.6, 11.4, 8.9, 4.0 organisms x 104) showed a. quadratic effect (P<0.05) to Saccharomyces cerevisiae dose. Total tract digestibility of DM, NDF and ADF were not affected, by treatments. Microbial culture with Saccharomyces cerevisiae at different doses did, not improve either fermentation or digestion in sheep fed, a, corn stover diet. © GSP, India.
