本研究的目的是表征微钙蛋白酶和钙蛋白酶抑制素基因多态性的等位基因和基因型频率，并评估它们与Nellore牛的肉嫩度和动物生长的相关性。我们评估了605只24月龄的Nellore动物，平均屠宰时。对分子标记CAPN 316、CAPN 530、CAPN 4751、CAPN 4753和UOGACAST 1确定多态性。肉嫩度的分析，在7，14，和21天的成熟进行的样品之间获得的第12和第13肋骨和剪切使用华纳Bratzler剪切力的胸最长肌。对于标记CAPN 4751，在成熟的第7天、第14天和第21天，对于标记CAPN 4753，以及对于标记UOGCAST 1，在第14天和第21天，观察到对肉嫩度的显著影响。对于标志物的基因型组合，结果对于组合CAPN 4751/UOGCAST 1在三个成熟期和CAPN 4753/UOGCAST 1在成熟的第14天和第21天是显著的。
The objectives of this study were to characterize the allelic and genotypic frequencies of polymorphisms in the µ-calpain and calpastatin genes, and to assess their association with meat tenderness and animal growth in Nellore cattle. We evaluated 605 Nellore animals at 24 months of age, on average, at slaughter. The polymorphisms were determined for the molecular markers CAPN316, CAPN530, CAPN4751, CAPN4753, and UOGACAST1. Analyses of meat tenderness at 7, 14, and 21 days of maturation were performed in samples of longissimus thoracis obtained between the 12th and 13th rib and sheared using a Warner Bratzler Shear Force. Significant effects were observed for meat tenderness at days 7, 14, and 21 of maturation for the marker CAPN4751, at day 21 for the marker CAPN4753, and at days 14 and 21 for the marker UOGCAST1. For genotypic combinations of markers, the results were significant for the combination CAPN4751/UOGCAST1 in the three maturation periods and CAPN4753/UOGCAST1 at days 14 and 21 of maturation.
