植物提取物的特性及其在母猪生产中的应用

Plant Extracts: Characteristics and Application in Sow Production

母猪繁殖性能是决定猪场生产水平和经济效益的关键因素,而我国母猪年生产力与欧美发达国家还存在明显差距。尽管抗生素作为饲料添加剂在一定程度上改善了母猪繁殖性能,但抗生素在饲料中的过度使用会导致耐药菌的产生以及肉制品残留等问题,危害人类的身体健康和生态环境。植物提取物是用物理或者化学方法,从植物中提取的含有多种天然生物活性物质的植物源添加剂产品。近年来,植物提取物作为抗生素替代物在母猪生产中的应用得到了广泛关注。本文结合国内外研究进展,对植物提取物的特性及其对母猪生产性能的影响进行综述,旨在为植物提取物在母猪生产中的应用进行更深入的研究提供参考。

The reproductive performance of sow s is a primary factor that determines production level and profitability in sw ine enterprise,w hile the piglets number per sow per year in China still w as low er than in USA and EU. Although the use of antibiotics improving the performance of sow s,but the over-use of antibiotics in the diets has caused problems such as bacterial resistance and drug residue in pork product,w hich is harmful for health of human and the ecological environment. Plant extracts are phytogenic products consisting a variety of natural active components,w hich are produced by physical or chemical extraction of natural plants. In recent years,plant extracts,as the alternatives to antibiotics,have attracted increased attention from the sow s industries. Referring to domestic and oversea research,this paper review ed the characteristic of plant extracts and effects on performance of sow s,as w ell as the actual application effects in practice so as to provide a reference for further study in the application of plant extracts in sow s feeding.
