【摘要】：发酵全混合日粮(fermented total mixed ration,FTMR)是将充分混合的全混合日粮(TMR)用专业青贮打捆机压实,然后使用青贮裹包机利用塑料拉伸膜将其紧紧密封造成密封厌氧的环境,进行无氧发酵而制作出的营养搭配合理、能够长期贮存的日粮。该发酵方式制作的TMR不仅具有普通TMR的优点,而且稳定性良好,可降解转化饲料中的抗营养因子,从而提高饲料安全性,同时可以改变原料理化性状,提高饲料利用率。这种发酵日粮可以长时间存放,方便运输,使不具备TMR生产条件的中小养殖户也能使用TMR日粮,也有利于即将建设的奶牛小区,降低小区建设投资成本。文章在FTMR的优点、制作条件、发酵品质、饲料副产物的利用以及实际生产应用效果等方面进行了综述,以推动这种新型奶牛饲喂技术的推广和应用,促进奶牛养殖业的健康发展。
[Abstract]:(fermented total mixed ration Mr is an environment in which a fully mixed diet (TMR) is compacted with a professional enlasser, and then sealed tightly by a plastic stretch film to create a sealed anaerobic environment. The nutrition of anaerobic fermentation is reasonable and can be stored for a long time. The TMR prepared by this fermentation method not only has the advantages of common TMR, but also has good stability. It can degrade and transform the anti-nutrition factor in feed, thus improve the feed safety, change the physical and chemical properties of raw materials and improve the feed utilization ratio. The fermenting ration can be stored for a long time and convenient for transportation, so that the small and medium-sized breeders who do not have the conditions of TMR production can also use the TMR diet, which is also beneficial to the dairy cattle plot to be built, and to reduce the investment cost of the community construction. In this paper, the advantages of FTMR, production conditions, fermentation quality, utilization of feed by-products and practical application effect were reviewed in order to promote the popularization and application of this new type of cow feeding technology. To promote the healthy development of dairy cattle breeding industry.
