| 摘 要： | Leptin（瘦素）是肥胖基因ob基因的表达产物，由脂肪细胞分泌，与下丘脑Leptin受体结合，可抑制食欲中枢，减少进食量，并通过兴奋交感神经系统，促进脂肪分解，增加产热，从而发挥降低体重，提高瘦肉率的功能。对Leptin的生物学功能及其对脂肪沉积的调控作用进行综述，以期为营养上调控畜禽肉品质，以及生产优质畜禽产品提供理论依据和科研基础。

| Abstract: | Leptin is the expression product of obese gene(ob gene).Leptin is secreted by adipocytes and combined with hypothalamic leptin receptor so as to inhibit appetite centers and decrease food intake,furthermore it could improve lipolysis and increase heat production by exciting nervous system so as to decrease body weight and increase lean meat percentage.The biological function of leptin and the regulatory effect on fat deposition were summarized in order to provide theoretical basis for regulating the quality of livestock and poultry meat and producing high-quality livestock and poultry products. |
