嗅觉与味觉对动物采食作用研究进展

良好的采食行为是动物机体维持生长发育和提高生产性能的基础,而嗅觉和味觉是动物采食过程中最重要的两种感官感受,它们分别由嗅觉受体和味觉受体基因决定,这些受体基因家族是哺乳动物基因组中较大的基因家族,不仅在感觉器官中表达,还广泛表达于呼吸、消化、生殖等系统中。作者对中国羊肉消费和羊的饲养情况,当前嗅觉、味觉及其受体基因的最新研究进展,嗅觉和味觉在动物采食中的作用和机制,以及嗅觉和味觉在畜禽养殖中的应用进行了综述,为研究嗅觉和味觉在动物采食尤其是羊上的作用提供参考。

Research Progress on Effects of Olfactory and Taste on Animal Food Intake

Good food intake behavior is the basis of maintaining the growth and development of animal and improving production performance.Olfaction and taste are two important senses in the progress of animal food intake.They are determined by olfactory receptor genes and taste receptor genes respectively,which are relatively large gene family in mammalian genomes.They express not only in the sense organs,but also widely in the respiratory,digestive,reproductive and other systems.This paper analyzed the consumption of mutton and sheep breeding in China.It gave an overview of the latest research progress on the olfaction,taste and their receptor gene.Finally,the function and mechanism of olfaction and taste in animal food intake,and the utilization in livestock production were expounded.This paper provided a theoretical reference for the study of the sense of olfaction and taste in animal food feeding especially in sheep.
