【摘要】：高產反芻動物采食大量的谷物淀粉為機體提供能量的同時,也會增加瘤胃與后腸道酸中毒的概率。合理調控淀粉在反芻動物胃腸道的消化率與消化速率,可改善谷物籽實淀粉的利用效率,提高反芻動物的生產性能。本文介紹了淀粉的分子結構,分析了不同谷物籽實源淀粉晶體結構、類型、顆粒大小與形態(tài)及組成成分的差異,探討其對能量與蛋白質利用效率及瘤胃與后腸道健康的影響,為反芻動物選擇合理的能量飼料提供參考。
[Abstract]:High yield ruminants fed a large amount of grain starch to provide energy, but also increased rumen and post-intestinal acidosis probability. Reasonably regulating the digestibility and digestion rate of starch in the gastrointestinal tract of ruminant can improve the utilization efficiency of grain seed starch and improve the production performance of ruminant. In this paper, the molecular structure of starch was introduced, the crystal structure, type, particle size, morphology and composition of starch from different grains were analyzed, and the effects of starch on energy and protein utilization efficiency, rumen and rumen health were discussed. It provides reference for ruminant to select reasonable energy feed.
