氨基酸与母猪营养

母猪饲养是养猪生产中最重要的环节之一。母猪的营养尤其是蛋白质和氨基酸营养不仅直接影响仔猪的生长性能,而且也对母猪的使用年限和繁殖性能会产生很大影响。母猪蛋白质及氨基酸营养受品种、胎次、母猪体况、产仔数、泌乳量、采食量、哺乳期长短等诸多因素影响,增大了母猪氨基酸营养的研究难度。同时母猪个体较大、研究成本高、试验群体偏小、数据采集困难以及试验误差较大等问题也限制了母猪蛋白质及氨基酸营养的系统研究。本文对母猪的氨基酸营养进行综述,旨在为养猪生产实践中母猪日粮的合理配制提供参考。

Amino Acids and Sows' Nutrition

Sow rearing is one of the most important links in pig production. The nutrition of sows, especially protein and amino acids, not only directly affects the performance of piglets, but also has a great impact on the longevity and productivity of the sows. Because there are many factors which affect the amino acid and protein requirements of sows, such as breed, sow parity, health condition, litter size, milk yield, feed intake, lactation period and so on, which increased the research difficulty of amino acid nutrition of sows. At the same time, large body weight, high research cost, small experimental qualitity, difficulties in data collection and large experimental errors also limited the systematic study of protein and amino acid nutrition in sows. This paper summarized the amino acid nutrition of sows, aiming to provide reference for the optimize formulation of sow in practice.
