Carcass composition, meat quality, calpain activity, fatty acid composition, and ribonucleotide content were examined and compared between male Southern Thai native goats (NG, n = 10) and three-way crossbred goats (CG, 50% Boer × 25% Saanen × 25% Southern Thai native, n = 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.

泰国南部本土山羊和三向杂交山羊的胴体组成、肉质、钙蛋白酶活性、脂肪酸组成和核糖核苷酸含量

检查并比较了雄性泰国南部本地山羊（NG，n = 10）和三向杂交山羊（CG，50% Boer × 25% Saanen × 25% 泰国南部本地人，n= 10）。所有动物都喂食 1.5% 体重的浓缩物（16% 的蛋白质和 70% 的总可消化营养素）和新鲜的纳皮尔草 4 个月。在饲养期结束时，两个基因型之间的最终重量没有显着差异。CG的胴体、骨头和脂肪的百分比高于NG。NG 在死后 24 小时呈现较低的剪切力值、不溶性和总胶原含量，但较高的胶原溶解度和钙蛋白酶 1 活性。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，核糖核苷酸的量在两种基因型之间没有显着差异。
