提高哺乳母猪采食量的研究进展

Advances in increasing feed intake in lactating sows

哺乳期母猪采食量会直接影响哺乳母猪的泌乳力,从而影响哺乳仔猪生长性能、断奶仔猪生产性能、母猪下次发情的时间及状态,保证哺乳母猪足够的营养摄入是养殖过程中重要的组成部分。影响哺乳母猪采食量的因素很多,如猪种、环境、温度、基础日粮组成、饲喂方式等。本文综述了提高哺乳母猪采食量的方法,为继续研究和在实际中提高哺乳母猪采食量提供依据。

Feed intake of lactating sows directly affects milkability,thus affecting growth performance of suckling piglets and weaning piglets,time and state of next estrus of sows.Ensuring adequate nutrition intake of lactating sows is an important part of the breeding process.There are many factors affecting feed intake of lactating sows,such as pig species,environment,temperature,basic diet composition,feeding mode,etc.In this paper,the methods of increasing feed intake of lactating sows were summarized,in order to provide the basis for further researches and actual improvement of feed intake of lactating sows.
