摘  要：
以6头体重35 kg左右、安装永久性瘤胃瘘管的健康羯羊为瘤胃液供体动物,用持续人工瘤胃装置(RUSITEC),基础日粮混合料为底物进行体外发酵试验,研究添加富含植物次生代谢物的金露梅与珠芽蓼草粉对瘤胃发酵的影响,以筛选天然饲料添加剂。结果表明,基础日粮中添加10%金露梅和10%珠芽蓼草粉与普通基础日粮之间,发酵液pH、甲烷、挥发性脂肪酸的产生量及干物质消失率差异均不显著(P>0.05),但有降低甲烷产量、提高干物质消化率的趋势。因此,在本试验条件下,添加10%金露梅和10%珠芽蓼草粉对瘤胃发酵的作用不显著,不适合做饲料添加剂。

摘  要：
The 6 healthy wether,weight about 35 kg,was fitted with permanent rumen fistula as rumen fluid donor,with continuous artificial rumen device(RUSITEC). Basic diet mixture as a substrate in vitro fermentation experiment,the study was done to add grass powder of Potentilla fruticosa L. and Polygonum viviparum L. rich in plant secondary metabolites on rumen fermentation in RUSITEC,with screening of natural feed additives. The results show that the yield and dry matter disappearance rate of fermentation liquid pH,methane and volatile fatty acid had no significant difference(P > 0.05)between basic diets supplemented with grass powder of 10% Potentilla fruticosa L. and 10% Polygonum viviparum L. and ordinary diet,but there is a trend to increase the dry matter degradation and decrease the methane production. Therefore, under the conditions of this experiment,the effect of adding grass powder of grass powder of 10% Potentilla fruticosa L. and 10% Polygonum viviparum L. on rumen fermentation was not significant,it is not suitable to choose as a feed additive.
