The aim of the study was to compare the certain carcass and meat quality traits and also fatty acid composition of goat kids from indigenous breeds (Gokceada and Hair Goat) and dairy breeds (Saanen and Maltese). A total 40 male kids from Saanen, Gokceada, Maltese and Hair Goat breeds were collected from commercial farms after weaning. Kids were finished for 56 days with grower concentrate and alfalfa hay in the sheepfold until slaughter. Higher mean values were found for Saanen kids in terms of slaughter weight, hot carcass weight and real dressing compared with Maltese, Hair Goat and Gokceada kids under the same intensive conditions. On the other hand, there were no significant differences between breeds in terms of instrumental meat quality traits, except meat colour. Meat from Gokceada and Hair Goat kids had higher lightness and Hue angle values than Saanen kids after 24 h of blooming. High meat redness values were observed for Saanen kids after 0 and 1 h of blooming. Panellist appreciated cooked meat from Saanen and Maltese kids in overall acceptability. If the fatty acid composition of meat was taken into consideration, kids from Saanen and Gokceada breeds displayed better values, because of the lower ƩSFA percentage and higher desirable fatty acids (C18:0 + ΣMUFA + ΣPUFA) percentage than Maltese and Hair Goat kids. Our results indicate that male kids for Saanen which is dairy breed could be assessable for quality goat meat production.
本研究的目的是比较本地品种（戈克恰达山羊和毛用山羊）和乳用品种（萨能山羊和马尔他山羊）的山羊羔的某些胴体和肉质性状以及脂肪酸组成。断奶后从商业农场收集了总共40只来自萨能山羊、戈克恰达山羊、马尔他山羊和毛用山羊品种的雄性羔羊。羔羊在羊圈中用育成浓缩料和苜蓿干草育肥56天直至屠宰。在相同的集约化条件下，与马尔他山羊、毛用山羊和戈克恰达山羊的羔羊相比，萨能山羊羔羊在屠宰体重、热胴体重和实际屠宰率方面的平均值更高。另一方面，除肉色外，各品种在仪器测定的肉质性状方面没有显著差异。戈克恰达山羊和毛用山羊羔羊的肉在放置24小时后比萨能山羊羔羊具有更高的亮度和色调角值。萨能山羊羔羊在放置0小时和1小时后肉的红色值较高。评判员对萨能山羊和马尔他山羊羔羊的熟肉总体可接受性评价较高。如果考虑肉的脂肪酸组成，萨能山羊和戈克恰达山羊品种的羔羊表现出更好的值，因为它们的饱和脂肪酸总量百分比更低，而所需脂肪酸（C18:0 + 单不饱和脂肪酸总量 + 多不饱和脂肪酸总量）百分比高于马尔他山羊和毛用山羊的羔羊。我们的结果表明，乳用品种萨能山羊的雄性羔羊可用于优质山羊肉生产的评估。
