添加剂对华北驼绒藜青贮发酵品质和体外消化率的影响

以华北驼绒藜(Ceratoides arborescens(Losinsk.)Tsien et C.G.Ma)为研究材料,探讨添加剂处理对其青贮品质和体外消化率的影响。试验设置了对照、乳酸菌和纤维素酶共10个处理组,调制青贮饲料,45 d后开封并取样分析。结果表明:0.01%Lalsil Dry可以明显提高ADF体外消化率(P<0.05)。纤维素酶处理的乳酸含量明显高于对照(P<0.05),其中0.03%的添加量还明显降低了pH值、氨态氮和NDF含量(P<0.05)。混合添加处理的乳酸含量均明显高于对照,NPN明显低于对照(P<0.05),且LM3+CF3显著降低了华北驼绒藜青贮饲料的pH值和NDF的含量(P<0.05),明显提高了ADF的体外消化率。

Effect of Different Additives on Fermentation Quality and in Vitro Digestibility of Ceratoides arborescens (Losinsk.) Tsien et C. G. Ma silages

Ceratoides arborescens(Losinsk.) Tsien et C.G.Ma is a kind of promising feeds as it is rich in crude protein,calcium and so on.However,there are few researches available on its processing and utilization methods,especially for silage.A laboratory-scale experiment was conducted using C.arborescens to evaluate the effect of different additives including Lalsil Dry(0.001%,0.002%,0.01%),cellulase(0.003%,0.006%,0.03%),and Lalsil Dry+cellulase(0.001%+0.003%,0.002%+0.006%,0.01%+0.03%) on the ensiling effects and i...
