摘要
日粮中的糖类、脂类、蛋白质、维生素、无机盐、水和膳食纤维七大类营养物质,是维持动物机体正常生理机能不可缺少的要素,也是生命活动的物质基础。但由于日粮种类、形态、来源、营养水平、动物品种和年龄阶段等所遇到的问题不同,从而影响的结果不尽相同。而日粮营养水平会对动物的肠胃消化吸收造成一定的影响,反映在动物代谢上,会影响肠道微生物、激素和生长因子等的变化,进而影响动物的生长发育。因此,本文重点阐述了近年来日粮营养中能量、碳水化合物、蛋白质、矿物质和维生素水平对动物生长发育的影响,通过合理配制日粮,科学调整营养水平,以期为我国动物养殖工作带来一些积极的参考。
Seven kinds of nutrients in the diet are carbohydrates, lipids, proteins, vitamins, inorganic salts, water and dietary fiber, which are indispensable elements to maintain the normal physiological function of animals and the material basis of life activities. However, due to the different problems encountered in diet types, forms, sources, nutritional levels, animal breeds and age stages, the results affected are not the same. The nutritional level of the diet will have a certain impact on the digestion and absorption of the animal’s gastrointestinal and gastrointestinal levels. This is reflected in the animal’s metabolism, and will affect the changes in intestinal microbes, hormones and growth factors, which in turn affect the growth and development of the animals. Therefore, this paper focuses on the influence of energy, carbohydrate, protein, mineral and vitamin levels in dietary nutrition on the growth and development of animals in recent years, and scientifically adjust the nutritional level through rational preparation of dietary, in order to bring some positive references for the work of animal breeding in China.
