Evaluation of two yeast cultures ( Saccharomyces cerevisiae) on ruminal fermentation and digestion in sheep fed a corn stover diet

A metabolism trial was conducted to evaluate the effect of two direct-fed microbial cultures containing Saccharomyces cerevisiae on ruminal fermentation and digestibility. Additives were added intraruminally to obtain a similar CFU (3×10 8). Twelve Suffolk sheep with ruminal cannula (29 kg BW) were...

Description
Summary:A metabolism trial was conducted to evaluate the effect of two direct-fed microbial cultures containing Saccharomyces cerevisiae on ruminal fermentation and digestibility. Additives were added intraruminally to obtain a similar CFU (3×10 8). Twelve Suffolk sheep with ruminal cannula (29 kg BW) were assigned to a completely randomized design where treatments were control group (CG), 3 g day −1 of Yea-Sacc 1026 (YS, 1×10 8 CFU g −1) or 0.015 g day −1 of Levucell (LC, 20×10 9 CFU g −1). Diet was based on corn stover (66.5%), sorghum grain (23.5%), molasses (8.6%) and urea (1.4%). Ruminal pH was lower ( p
