味觉在检测食物中的营养成分或有毒物质方面起着重要的作用，它与动物的摄食行为密切相关。因此，阐明鸡的味觉感受系统可以提高我们对家禽营养的理解，并将有助于开发新的替代饲料。本文就鸡的味蕾、味觉感受器和味觉的研究进展作一综述。最近的研究揭示了鸡口腔味蕾的分布以及多种味觉受体在鸡口腔和胃肠道组织中的表达。功能分析表明，鸡的味觉受体可以识别氨基酸，脂肪酸，和各种各样的苦味化合物，和鸡苦味受体的活动可以被6-甲氧基黄烷酮抑制。行为分析表明，鸡可以对氨基酸，苦味刺激，咸味刺激，酸味刺激和脂肪酸做出反应，但鸡对糖的味觉敏感性较低。最近的组织学，分子生物学和行为学证据表明，鸡有发达的营养感应系统。
The sense of taste plays an important role in the detection of nutrients or toxic substances in foods, and it is deeply related to the feeding behaviours of animals. Thus, elucidation of the taste-sensing system in chickens can improve our understanding of poultry nutrition and will be useful to make new alternative feedstuffs. In this review, we summarise the recent advances in the study of taste buds, taste receptors and taste perception in chickens. Recent studies have revealed the distribution of taste buds in the oral cavity of chickens and the expression of multiple taste receptors in the oral and gastrointestinal tissues of chickens. Functional analyses have shown that chicken taste receptors can recognise amino acids, fatty acids, and a wide variety of bitter compounds, and the activities of chicken bitter taste receptors can be inhibited by 6-methoxyflavanone. Behavioural analyses have demonstrated that chickens can respond to amino acids, bitter stimuli, salty stimuli, sour stimuli and fatty acids, but chickens have a low taste sensitivity for sugars. The recent histological, molecular biological, and behavioural evidence indicates that chickens have well-developed nutrient-sensing systems.
