| 摘 要： | 饲料的适口性是动物对饲料的气味及口感等的综合感知,在一定程度上影响动物的采食量,而动物的采食量与生产性能有较高的正相关。气味的感知主要源于鼻腔内嗅觉神经的突起,口感的感知主要由口腔内的味觉受体来完成,主要味觉受体包括甜味受体、鲜味受体和苦味受体等。食物进入胃肠道后,胃肠道上的味觉受体感应程度可影响并调节动物对食物的吸收率和采食行为。本文主要介绍了近年来有关鼻腔的嗅觉受体、口腔内的味觉受体和胃肠道内味觉受体和信号传递等相关研究,并就调味剂在动物生产上的应用进行综述,为调味剂的应用及相关研究提供一定借鉴。

| Abstract: | Palatability of animal feed, to a certain extent, affects feed intake, animal feeding behavior and growth or production efficiency. For animals the palatability of diet can be mainly affected by both smells and tastes of diet. Smell perception is achieved by the olfactory nerve prominence perception stems mainly from the nasal cavity(OR). Taste perception is completed through taste receptors in the mouth. This paper reviewed studies on smell relevant nasal olfactory receptors taste receptors in mouth and gastrointestinal tracts, the related mechanism of signal transmission as well as the application of palatability enhancers in ruminant animal production. |
