旨在探究青贮剂对再生稻头季全株青贮品质和体外瘤胃发酵特性的影响。以再生稻头季全株为青贮原料,在青贮中分别添加植物乳杆菌(60%)+纤维素酶(30%)+木聚糖酶(10%)、植物乳杆菌(70%)+粪肠球菌(20%)+纤维素酶(5%)+半纤维素酶(5%)、植物乳杆菌(30%)+粪肠球菌(60%)+纤维素酶(5%)+半纤维素酶(5%)、等量水为对照(依次记为N_(1)、N_(2)、N_(3)和CK组,各组添加量为500 g·t^(-1)鲜重)。青贮45 d后开包取样,分析其青贮品质和体外瘤胃发酵特性。结果表明:1)青贮结束后,N_(1)、N_(2)和N_(3)组的总能显著高于CK组(P

This experiment was conducted to investigate effects of silage additives on quality and in vitro rumen fermentation characteristics of first season ratoon rice whole-crop silage. The experiment compared three fermentation-enhancing preparations of bacterial and enzyme additives, added at 500 g•t-1 fresh weight when ensiling whole crop ratoon rice, and a control (CK, 500 g•t-1 water). The additive treatments were: N1, Lactobacillus plantarum (60%)+cellulase (30%)+xylanase (10%); N2, L. plantarum (70%)+Enterococcus faecalis (20%)+cellulase (5%)...
