摘  要：
幼龄反刍动物处于十分重要的生长阶段,连同后续阶段均会对其成年后的总体发育水平、组织器官成熟、免疫系统快速构建、泌乳以及繁殖等性能造成影响。开食料的采食、饮水量以及断奶后日粮的营养成分等都会对幼龄反刍动物的瘤胃发育产生客观作用。日粮营养水平会反映在动物代谢情况上,并对其生长性能产生一定作用,并且还会改变机体激素和生长因子情况反映于其生长发育情况。而影响幼龄反刍动物生长发育速度和瘤胃发育程度的重要因素取决于日粮中的能量和蛋白质水平。科学调整能量水平,能够有效增加其断奶期的采食量;确保蛋白质饱和也能够给瘤胃微生态带来必需的氮,由此促进反刍动物消化情况的有效改善,避免出现营养不良等。但是由于试验日粮来源、试验动物品种及试验时期所遇到的各个问题不同,所导致的结果都会不同。因此,文章重点阐述了近些年来日粮中不同能量和蛋白质水平对幼龄反刍动物生长性能和瘤胃发育程度的影响,以期为我国相关日粮配制工作带来一些积极的参考。

摘  要：
Young ruminants are at a very important stage of growth, which, together with the subsequent stages, can affect the overall development level, tissue and organ maturation, rapid immune system construction, lactation,and reproductive performance. The intake of open food, the quantity of drinking water and the nutritional composition of the diet after weaning all have objective effects on the rumen development of young ruminants. Diet nutrition level will reflect in the animal metabolism, and growth performance to a certain extent, and will also change the body hormone and growth factors reflected in its growth and development. However, the important factors influencing the growth and development rate and rumen development degree of young ruminants depend on the energy and protein level in the diet. Ensuring protein saturation can also bring essential nitrogen to the rumen microecology, thus promoting effective improvement of ruminant digestion and avoiding malnutrition. But the results will vary depending on the source of the diet, the animal species and the problems encountered during the experiment. Therefore, the author focuses on the effects of different energy and protein levels in the diet on the growth performance and rumen development of young ruminants in recent years, hoping to provide some positive references for the relevant diet preparation work in China.
