摘要
动物长期使用抗生素可导致免疫力下降,引起畜禽内源性感染和二重感染,因此,开发绿色、高效、安全的新型饲用抗生素替代品成为当前饲料工业发展的热点。抗生素替代品种类较多,包括酸化剂、抗菌肽、中草药、微生态制剂等产品,具有安全、环保和效果显著等特点。重点对酸化剂、γ-氨基丁酸、水解单宁酸、植物提取物、抗菌肽、酶制剂、益生菌、中草药等在养猪生产中的应用进行综述,为抗生素替代品的研发提供参考。
Long-term use of antibiotics in animals leads to declined immunity and causes endogenous infections and double infections in livestock and poultry.Therefore,the development of green,high-efficient and safe new feed antibiotic substitutes(ASs)has become a hot spot in the development of current feed industry.There are many types of ASs,including acidulants,antibacterial peptides,Chinese herbal medicines,microecological preparations and other products,and they are considered safe,environmentally friendly and effective.This article reviews the application of acidulants,γ-aminobutyric acid,hydrolyzed tannic acid,plant extracts,antimicrobial peptides,enzyme preparations,probiotics,Chinese herbal medicines,etc.in pig production,in hoping to provide references for the development of ASs.
