摘　　要：用A(0.32％甲酸+0.04％硫酸+0.04％磷酸)、B(0.25％甲酸+0.15％6N盐酸)、D(0.4％甲酸+0.27％甲醛)和E(0.4％甲酸+2.0％糖蜜)4种添加剂进行的袋装苜蓿青贮及其动物饲喂试验表明,D、E两种添加剂对提高青贮品质有显著作用,用其饲喂1岁公羊日增重分别比对照组高9.71％和20.76％,粗蛋白质消化率分别比对照组高0.73％和2.79％,氮素存留率分别比对照组高24.71％和22.51％,每公斤体增重分别比对照组少消耗饲料14.11％和11.67％。Results of added four various additives(A—0. 32% acetic acid + 0. 04% sulpharic acid + 0. 04% phosphorous acid , B—0. 25 formic acid + 0. 15% 6N hydrochloric acid, D—0. 4% formic acid + 0. 27% formaldehyde and E—0. 4% formic acid+ 2. 0% molasses, of fresh weight respectively) lucerne ensilaged with polythene bags and silage for animal's feeding trial showed that both D and E additive had a significant effect on improving quality of silages. Liveweight gain of yearling male sheap fed with silages treated by D and E additives were 9. 71% and 20. 76% ,crude protein digestibility were 3. 9% and 2. 5%. Organic matter digestibility were 2. 8% and 0. 73%, rate of retained N were 24. 71% and 22. 51%, and feed consumption decreased per LWG 14. 11 % and 11. 67% higher than those of untreated, respectively.
