植物提取物在断奶仔猪饲粮中应用的最新研究进展

Recent progress in the application of plant extracts in the diet of weaned piglets

在生猪养殖过程中,抗生素的长期使用会使仔猪产生细菌耐药性,从而使免疫力和生产性能下降,死亡率上升。而作为抗生素替代品的植物提取物添加剂应用于断奶仔猪饲粮,能够促进断奶仔猪的生长性能,改善肠道菌群平衡,提高机体的抗氧化性能,有利于仔猪的健康。本文主要综述了近些年植物提取物在断奶仔猪中应用所产生的影响及其作用机理,以期为植物提取物在断奶仔猪饲粮上的应用提供科学依据。

In the process of pig breeding,the long-term use of antibiotics will cause bacterial resistance in piglets,reduce immunity,decrease production performance and increase mortality.The application of plant extract additive as antibiotic substitute in the diet of weaned piglets can promote the growth performance of weaned piglets,improve the balance of intestinal flora,improve the antioxidant performance of body,and be beneficial to the health of weaned piglets.In order to provide some scientific basis for the application of plant extracts in the diet of weaned piglets,the influence and mechanism of some plant extracts in recent years were reviewed in this paper.
