酸化剂在早期断奶仔猪生产中的应用研究进展

Progress of research on the application of acidifiers in early weaned piglet production

仔猪因消化系统不完善,其饲养是猪生产中死亡率较高的因素之一。另外,欧盟及中国禁止抗生素在动物饲料中应用,因此,寻找新的成长促进剂迫在眉睫。有机酸和无机酸及其盐类因其有效和安全的特性逐渐替代抗生素,在断奶仔猪的生产中被广泛应用,其使用受环境因素、类型和剂量、日粮组成、动物自身、日粮离子平衡等诸多因素影响,酸化剂的正确使用能够给畜牧业生产带来良好的效果。本文综述酸化剂的分类、作用、影响因素及其对断奶仔猪生长性能、免疫性能、抗氧化性能、肠道健康和血液生化指标的影响,旨在为酸化剂在断奶仔猪实践生产中的应用提供参考。

Piglets have imperfect digestive system,and their feeding is one of factors leading to high mortality in pig production.Since the EU and China banned the application of antibiotics in animal feed.Therefore,looking for new growth promoters is urgent.Organic acids and inorganic acids and their salts are gradually replacing antibiotics due to their effective and safe characteristics,and are widely used in the production of weaned piglets.Their use is affected by many factors,such as environmental factors,type and dosage,dietary composition,animal factors,dietary ion balance,etc.The correct use of acidifiers can bring good results to animal husbandry production.This paper reviewed the classification,role,influencing factors of acidifiers and their effects on growth performance,immune performance,antioxidant performance,intestinal health and blood biochemical indexes of weaned piglets,aimed to provide a reference for the application of acidifiers in the practical production of weaned piglets.
