多不饱和脂肪酸在犬猫毛发质量改善中的作用机理及应用研究进展

Research Progress on Mechanism of Polyunsaturated Fatty Acids and Its Application in Improving Coat Hair Health of Dogs and Cats

毛发作为犬猫最直观的基本特征,具有保护皮肤、观赏性等重要功能,一直以来备受宠物主人关注。当犬猫的皮肤与毛发健康处于不佳状态时,会引起皮肤炎症、瘙痒甚至脱毛等异常状况,严重影响宠物健康。如何维持和改善犬猫毛发健康状态是宠物营养学中值得研究的问题。多不饱和脂肪酸(polyunsaturated fatty acids,PUFA)是一类含2个或2个以上双键的长链脂肪酸,已被证明对皮肤和毛发健康具有积极的改善作用,在犬猫毛发健康产品的开发中具有良好的应用前景,是近年来的研究热点之一。作者综述了PUFA对维持和改善犬猫毛发健康的作用机理,以及动物、植物、微生物3种来源的PUFA在犬猫毛发健康产品中的应用研究进展,以期为未来PUFA在犬猫毛发健康产品中的开发与应用提供参考。

As a basic characteristic of dogs and cats,also being their most apparent features,coat hair serves important functions such as skin protection and ornamental values,and has always been of great concern to pet owners.When the coat hair of dogs and cats are in poor state,it can lead to abnormal conditions such as skin inflammation,pruritus,and even hair loss.The abnormal conditions significantly impacting the overall health of pets.Therefore,investigating how to maintain and improve the healthy state of coat hair in dogs and cats is a worthwhile research question in the field of pet nutrition.Polyunsaturated fatty acids(PUFA),a type of long-chain fatty acids containing two or more double bonds,have been shown to have positive improvement effects on coat hair health,making PUFA promising for the development of products aimed at improving coat hair health in dogs and cats.The authors summarized the mechanism of PUFA in maintaining and improving coat hair health in dogs and cats,and the application of PUFA from animal,plant and microorganisms sources in pet hair health products,with a view to providing a reference for the development and application of PUFA in coat hair health products of dogs and cats in the future.
