本试验旨在评价两种直接饲喂的含酿酒酵母的微生物培养物对瘤胃发酵和消化率的影响。在腹腔内添加添加剂以获得相似的CFU （3 × 10(8)）。选取12只体重29 kg的瘤胃插管萨福克羊，采用完全随机设计，对照组（CG）添加3 g d (-1) Yea-Sacc(YS, 1 × 10（8) CFU g(-1)）或0.015 g d (-1) Levucell (LC, 20 × 10（9) CFU g(-1)）。饲粮以玉米秸秆（66.5%）、高粱谷物（23.5%）、糖蜜（8.6%）和尿素（1.4%）为主。瘤胃pH降低(p
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 (3x10(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, 1x10(8) CFU g(-1)) or 0.015 g day(-1) of Levucell (LC, 20x10(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
