Abstract

This paper aimed to study the associative effects of Alfalfa, Astragalus adsurgens, Gaodan grass, Chinese pennisetum and ryegrass. Introduced the combination of multiple-factors associative effects index (MFAEI) and feeding experiment, using two kinds of legume forage with alfalfa, Astragalus adsurgens and three kinds of grasses with Sudan grass, Chinese pennisetum and ryegrass as raw materials by the method of in vitro fermentation, tested the pH, gas production, microbial protein, volatile fatty acid, in vitro digestibility organic matter indexes determination of 3 repetitions, by the means of the MFAEI to design selection and the optimized combination. Through the test contrast analysis, with reasonable collocation of the roughage and the complementary between nutrients, the level of whole fermentation could significantly improve. The results showed that the MFAEI of six kinds of forage from high to low in turn was:group B> group C> group A> group D> group F> group E. According to the theory of MFAEI, two optimal combination from six kinds of forage combination is:group A, alfalfa:Astragalus adsurgens:Chinese pennisetum=40:40:20, the MFAEI is 1.13; group B, alfalfa:Astragalus adsurgens:Sudan grass=40:40:20, the MFAEI is 1.21.
