Carcass composition, meat quality, calpain activity, fatty acid composition, and ribonucleotide content were examined and compared between male Southern Thai native goats (NG, = 10) and three-way crossbred goats (CG, 50% Boer × 25% Saanen × 25% Southern Thai native, = 10). All animals were fed 1.5% body weight of concentrate (16% protein and 70% total digestible nutrients) and fresh Napier grass for 4 months. At the end of raising period, the final weight between the two genotypes was not significantly different. The percentage of carcass, bone, and fat of CG were higher than those of NG. NG presented lower shear force values, insoluble and total collagen content but higher collagen solubility and calpain-1 activity at 24 h postmortem. Additionally, NG meat was high in monounsaturated fatty acids but low in saturated fatty acids. However, the amount of ribonucleotide was no significant difference between two genotypes.
对泰国南部本地公山羊（NG，n = 10）和三元杂交山羊（CG，50%波尔山羊×25%萨能山羊×25%泰国南部本地山羊，n = 10）的胴体组成、肉质、钙蛋白酶活性、脂肪酸组成和核糖核苷酸含量进行了检测和比较。所有动物均饲喂占体重1.5%的精料（16%蛋白质和70%总可消化养分）和新鲜象草，持续4个月。饲养期结束时，两种基因型之间的最终体重无显著差异。CG的胴体、骨骼和脂肪百分比高于NG。NG在宰后24小时呈现较低的剪切力值、不溶性和总胶原蛋白含量，但胶原蛋白溶解度和钙蛋白酶-1活性较高。此外，NG肉的单不饱和脂肪酸含量高，但饱和脂肪酸含量低。然而，两种基因型之间的核糖核苷酸含量无显著差异。
