摘要:目前膳食纤文作为一种不消化多糖,在国内外医学和营养学界被视为“第七类营养素”,其具有改善肠道发育、调节动物肠道微生物平衡等重要的生理作用,逐渐成为学术界和普通百姓关注的物质,成为人们健康饮食不可缺少的营养素。然而膳食纤文在畜牧生产中的运用并不广泛,本实验拟通过在日粮中添加可溶性膳食纤文研究对断奶仔猪营养物质消化率的影响,为膳食纤文在仔猪饲料上的应用提供实验依据。结果表明,日粮中添加玉米淀粉为原料的膳食纤文不影响仔猪生产性能,可提高断奶仔猪干物质(DM)、有机物(OM)、蛋白质(CP)与粗灰分(ASH)的表观消化率,对钙(Ca)的表观消化率有提高的趋势,但对粗脂肪(EE)、磷(P)、铜(Cu)、和锰(Mn)的消化率没有影响。25689 毕业论文关键词:膳食纤文;断奶仔猪;营养物质;消化率;生产性能
Study of dietary fiber on performance and nutrient digestibility in weaned piglets
Abstract:Dietary fiber used as a indigestible polysaccharide, which is regarded as "seventh class of nutrients" in the field of medical and nutrition in the world, which can improve intestinal development, regulate the intestinal microbial balance of animals, and have other important physiological effects. Therefore, dietary fiber has been focused by the academic community and ordinary people, and become a healthy diet of people indispensable nutrients. However, the use of dietary fiber in livestock production is not extensive. The aim of this experiment was to research the effect of dietary fiber on the digestibility of nutrient in weaned piglets, the result was as follows: the added dietary fiber of corn starch source in feed did not increase performance, can improve the digestibility of dry matter, organic matter,crude protein and ash, and trend to increase the digestibility of calcium, however, had not affect the digestibility of phosphorus,ether extrac,copper, and manganese in weaned piglets.
Key words: Dietary fiber; weaned piglets; nutrients; digestibility; performance
