摘要: 钙蛋白酶系统在动物屠宰后肌肉蛋白质水解和肌肉嫩化过程中发挥重要的作用;脂肪酸结合蛋白参与脂肪酸的转运代谢,影响肌肉的嫩度、风味和多汁性,与背膘厚、大理石花纹、嫩度和系水力等肉用性状有较高关联度;生肌调节因子在肌肉分化过程中可控制启动成肌细胞的融合和肌纤维的形成;肌肉生成抑制素是控制肌肉生长的负调控因子,影响畜禽瘦肉率、改善肉质性状的重要营养基因。作者综述了钙蛋白酶系统家族、脂肪酸结合蛋白基因、生肌调节因子和肌肉生长抑制素等影响肉牛肉品质性状的基因,以期在肉牛育种选择中找到使产肉量和肉质得到同步提高的途径,进一步通过标记辅助选择来改善肉牛的肉质性状。

Abstract: Calpain system played an important role in muscle protein hydrolysis and muscle tenderization after animal slaughter. Fatty acid binding proteins affected muscle tenderness, flavor and juiciness, and had high relevance to backfat thickness, marbling, tenderness and water capacity of meat traits through taking part in the transport and metabolism of fatty acids. Myogenic regulatory factors controled the fusion of muscle cell and formation of muscle fiber during the muscle differentiation process. Myostatin, a negative regulator for muscle growth, could affect lean meat percentage of animal and better meat quality traits. Several meat quality candidate genes in cattle including calpain system family, fatty acid binding protein gene, myogenic regulatory factor, and myostatin were summarized in order to find the way to improve the quantity and quality of meat and further improve the meat quality traits through marker-assisted selection.
