摘　　要：中国是畜牧生产大国,总产绒量、总产肉量、总产毛量全球第一;但畜牧业生产力低下,集约化水平低。在今后的发展中应提高畜牧业生产水平,畜牧业生产要求集约化是大势所需。近年来,我国北方草原“三化”已受到全国的重视,各项减少草地载畜量的提议不断提出。对畜群进行调整是我们现在要面对的问题。畜群调整的原则是在合理载畜率的基础上获得持续的、最大的收益。本文总结了近年来国内外对畜群结构管理方面的研究,希望人们更多地了解国内外畜群结构管理的研究现况。China Animal production plays an important role in the world. Though its total Cashmere yield, total meat yield, and total wool yield are in the first place all over the countries, its productivity was very low. We should improve animal production in the future. Grassland degeneration was a serious problem in China, and coas concerade all over the country. Various suggestions of reduclng stocking rate were put forward. It is time we should come up with a method to solve this problem. Gaining a permanent,maximal yield based on the optimal stocking rate was the rules of livestock structure optimal management. This paper reviewed the research of livestock population management and hoped that people had a deep insight to livestock population management.
