【摘要】：幼齡反芻動(dòng)物飼糧的纖維性碳水化合物(FC)來(lái)源與組成對(duì)調(diào)控其生長(zhǎng)發(fā)育和瘤胃功能建立有重要作用,其來(lái)源各異,粒度不同,對(duì)正處于生長(zhǎng)期的幼齡反芻動(dòng)物的采食和消化、瘤胃液p H及瘤胃發(fā)育等生理參數(shù)的影響存在差異。本文綜述了近年來(lái)關(guān)于幼齡反芻動(dòng)物飼糧中性洗滌纖維(NDF)來(lái)源和粒度的研究,分別從生產(chǎn)性能、瘤胃發(fā)酵和瘤胃發(fā)育3個(gè)方面總結(jié)了二者對(duì)幼齡反芻動(dòng)物的影響,并對(duì)相關(guān)機(jī)制進(jìn)行了探討。
[Abstract]:The source and composition of fiber carbohydrate in young ruminant diet play an important role in regulating the growth and development of ruminants and the establishment of rumen function. Feeding and digestion of young ruminants in their growing stages. The effects of pH and rumen development on the physiological parameters of rumen fluid in ruminants were reviewed in this paper. The research on the source and size of NDFs in young ruminant diets were reviewed in this paper. The effects of rumen fermentation and rumen development on young ruminants were summarized and the related mechanisms were discussed.
