Abstract

Abstract: Omega-3 fatty acid is a type of polyunsaturated fatty acids that are widely present in nature and an important component of cell membranes,which mainly come from some marine fish and plant seeds such as flaxseeds.Omega-3 fatty acid can change the composition of cell membrane lipids,regulate the biosynthesis of eicosanoids,control gene expression and cell signal cascades,and have a positive impact on the health of animals.Adding an appropriate amount of Omega-3 fatty acid to the diet in dairy cows has significant benefits.It can effectively enhance the immunity of dairy cows,reduce the incidence of mastitis and reproductive diseases,and improve their reproductive performance.In addition,Omega-3 fatty acid can optimize the rumen microbial flora,promote the digestion and absorption of nutrients,and thereby increase milk production and milk quality.This article reviews the sources and in vivo transformation process of Omega-3 fatty acid,and focuses on summarizing their regulatory effects on the immune system,mastitis,reproductive performance and milk production performance of dairy cows,with the aim of providing a reference for the research and application of Omega-3 fatty acids as feed additives in dairy cow farming.

Key words: dairy cows; Omega-3 fatty acid; mastitis; reproductive performance; milk production performance
