There is little knowledge about the carcass potential of Turkish native goat breeds raised under different rearing conditions. It is necessary to compare the carcass characteristics of these breeds to minimize the effect of the rearing conditions. Therefore, this study aims to compare the growth, slaughter, and carcass characteristics of male kids at weaning age to eliminate the impact of rearing conditions. Kids born to Angora ( = 6), Hair ( = 6), Honamlı ( = 6), and Kilis ( = 6) Turkish native goat breeds, ranging in age from 2-3 years, were slaughtered at 90 days of weaning age and carcass characteristics were determined immediately. There were differences ( < 0.05) among breeds in terms of birth weight (BW) and daily weight gain (DWG) from birth to weaning age. Honamlı kids had higher BW and DWG than those of other breeds ( < 0.05). Similarly, carcass weights (hot-cold) and yields (hot-cold) of Honamlı kids were higher compared to kids born to other breeds ( < 0.05). Additionally, Honamlı and Hair kids had higher longissimus-dorsi (LD), and semitendinosus (ST) muscle weights compared to Kilis and Angora kids. Interestingly, Kilis kids had lower BW and DWG than those of other breeds ( < 0.05). There were significant differences ( < 0.05) among breeds in terms of non-carcass parts and organ weights. Positive correlations were calculated between cross-sectional area and weight (r = 0.793; < 0.01), length and weight (r = 0.723; < 0.01), and depth and weight (r = 0.698; < 0.01) in LD muscle of all kids. A similar correlation trend was calculated for the ST muscle (cross-sectional area and weight; r = 0.699; < 0.01, length and weight; r = 0.751; < 0.01, and depth and weight; r = 0.528; < 0.05) in all kids. In conclusion, the present study results showed that Honamlı kids could be used for fattening material due to their good carcass quality compared to other native breeds.
关于在不同饲养条件下饲养的土耳其本土山羊品种的胴体潜力，人们了解甚少。有必要比较这些品种的胴体特征，以尽量减少饲养条件的影响。因此，本研究旨在比较断奶期雄性羔羊的生长、屠宰和胴体特征，以消除饲养条件的影响。对安哥拉（n = 6）、毛发（n = 6）、霍纳姆利（n = 6）和基利斯（n = 6）这四个土耳其本土山羊品种2至3岁的羔羊在断奶90天时进行屠宰，并立即测定胴体特征。各品种在出生体重（BW）和从出生到断奶期的日增重（DWG）方面存在差异（P < 0.05）。霍纳姆利羔羊的BW和DWG高于其他品种（P < 0.05）。同样，与其他品种的羔羊相比，霍纳姆利羔羊的胴体重（热胴体 - 冷胴体）和产肉率（热胴体 - 冷胴体）更高（P < 0.05）。此外，与基利斯和安哥拉羔羊相比，霍纳姆利和毛发羔羊的背最长肌（LD）和半腱肌（ST）重量更高。有趣的是，基利斯羔羊的BW和DWG低于其他品种（P < 0.05）。各品种在非胴体部分和器官重量方面存在显著差异（P < 0.05）。在所有羔羊的LD肌肉中，横截面积与重量（r = 0.793；P < 0.01）、长度与重量（r = 0.723；P < 0.01）以及深度与重量（r = 0.698；P < 0.01）之间计算出正相关。在所有羔羊的ST肌肉中也计算出了类似的相关趋势（横截面积与重量；r = 0.699；P < 0.01，长度与重量；r = 0.751；P < 0.01，深度与重量；r = 0.528；P < 0.05）。总之，本研究结果表明，与其他本土品种相比，霍纳姆利羔羊因其良好的胴体品质可作为育肥材料。
