| In this study, Guangxi black goat as experimental animals, cultured in vit ro gas productionsystem48hours compared the sugar cane leaves, straw, cor n stalks nutritional value offour treatment methods. To find the right treatmen t roughage provides a theoretical basis.This paper consists of two parts, in vit ro gas production technique and rumen microbialpolymorphism analysis, the main results are as follows:1.Impact of a conventional nutrientsCane leaves ammoniated treatment of bacterial treatment on the crude pro tein content of sugarcane leaves has significantly improved. Alkaline treatme nt is reducing the crude protein content of sugar cane leaves. Four kinds of tr eatment can decompose to some extent, crude fiber, the effect is the best sila ge, followed ammoniated, alkaline, andbacteria processing the difference was not significant.Straw, ammoniated, bacterial treatment on the crude protein content of st raw hasincreased, alkaline treatment is to reduce the crude protein content of s traw, silagetreatment was not significant. Four kinds of treatment can decomp ose to some extent in the crude fiber straw. However, the four-way treatmen t difference was not significant.Corn stalks, ammoniated, ammoniated, bacterial treatment on the crude pr otein content ofcorn stalks have increased alkaline treatment is reducing the c rude protein content of corn stalks. Silage treatment was not significant. Fou r treatments can decompose to some extent, corn stalks in crude fiber, the mos t obvious effect of alkaline treatment, the other three treatments had no signi ficant difference2.In the degradation rate of dry matterJudging from the results, silage processing, ammoniated processing, sugar cane leaves and the control group was significantly alkaline treatment, dry matter degradation rate was significantly improved, but bacterial treatment wa s significantly lower than the contract group.For straw, silage processing, ammoniated treatment, alkaline treatment, straw tr eated with the control group showed significant bacteria, can increase the de gradation rate of dry matter, the effect of alkaline treatment is best, followe d by the ammoniated treatment,silage processing, bacteria.For corn stalks, silage processing, ammoniated treatment, alkaline treatment, c orn stalks and the control group was significantly bacterial treatment, can im prove dry matter degradation rate, the best deal is alkaline, followed ammoni ated treatment, silage treatment, bacterial treatment.3In gas productionFrom the experimental results point of view, the impact of treatment on thre e of four feed gas production are alkalizing> ammoniated> silage> Bacteria> control. Were able to show that the four ways to improve feed digestibilit y. The best alkalizing effect, followed ammoniated, silage, bacterial treatment.4On rumen microbial polymorphismTGGE patterns indicate different feed rumen microecologic various trea tments have different effects on the black goat. Considering all factors, th e best cane leaf silage, straw, corn stalks, alkalized best. |
