麻叶荨麻、羊草组合对乌珠穆沁羔羊表观消化率和瘤胃发酵参数的影响
Influences of Associative Effects between Leymus Chinensis and Urtica Cannabinaon Apparent Digestibility and Rumen Fermentation Parameters of Wuzhumuqin Lamb
摘要
Abstract
The experiment is conducted to study the effects of Leymus chinensis and Urtica cannbinau on apparent digestibility and rumen fermentation parameters of Wujumqin lamb.Using the completely randomized design,32 healthy Wujumqin lambs with same month-age and weight were randomly divided into 4 groups of similar weight,respectively fed with diet 1 (Native grass),diet 2 (Leymus chinensis:Urtica cannbinau=1∶0),diet 3 (Leymus chinensis:Urtica cannbinau=0∶1),diet 4 (Leymus chinensis:Urtica cannbinau=1∶1).The preliminary feeding period was 2 weeks,with the formal period being 2 months.The results showed that diet 3 had significantly lower dry matter digestibility,organic matter digestibility and protein digestibility than that of diet 2 at 30 th day (P<0.05),but the difference between diet 2 and diet 3 at 60th day were not significant (P>0.05);The NDF digestibility of diet 4 was significantly higher than that of diet 2 at 30th and 60 th day (P<0.05);The rumen ammonia concentration of diet 3 at 30th day and 60th day was significantly higher than other groups (P<0.05),the total VFA concentration of diet 3 was significantly lower than that of diet 2,with the ethylene propylene being significantly higher than diet 2 (P<0.05);The bacterial protein of rumen fluid of diet 3 in 30th day was less than diet 2,but there was no significant difference in the total rumen microbial protein content and pH among the groups (P>0.05).The above results show the ratio of Leymus chinensis and Urtica cannabina being 1∶1 does not affect Wuzhumuqin lamb's feed nutrient digestibility and rumen fermentation parameters,in addition,it can improve the digestibility of fiber material to a certain extent.关键词
