中文摘要：

采食量是制约哺乳母猪生产性能发挥的重要因素。酪酪肽作为一种典型的抑食因子，在调节摄食、消化道功能方面具有重要作用，成为关注的新热点。本文主要从酪酪肽的主要生物学特性和生理功能两方面进行综述，并对其在哺乳母猪养殖中的应用前景进行展望。

英文摘要：

Feed intake plays an important role in determining the production performance in lactation sows. As one of the typical feeding inhibitors, peptide tyrosine-tyrosine has important effects on negative-regulating feed intake and promoting digestion in animals. The main biological characteristics and physiological functions of peptide tyrosine-tyrosine, and its potential application in lactation sows are reviewed in this paper.
