Fifty-eight Karacabey Merino lambs were used to study the effects of feeding system (triticale pasture, oat pasture, or stall-fed), birth type (single or multiple), gender (male or female), and birth year (2016 or 2017) on various carcass and meat quality characteristics. Stall lambs had higher conformation (CS) and fatness (FS) scores, and higher meat * and * values than the two pasture groups, possibly due to higher fat content, while oat pasture lambs had the most tender meat. Single-born lambs had higher CS, FS, and Longissimus thoracis muscle section area, while females had higher subcutaneous and non-carcass fat deposits than their counterparts. Both single-born lambs and 2016-born lambs had higher meat * and * values than their counterparts. In conclusion, a pasture-based feeding system is more suitable for Karacabey Merino lambs than a stall feeding system, if lean meat and/or meat products are preferred. However, it should not be ignored that stall-fed lambs showed a better fattening performance in terms of conformation and fatness, during the same period.
58只卡拉卡贝美利奴羔羊被用于研究饲养系统(小黑麦牧场、燕麦牧场或舍饲)、出生类型(单胎或多胎)、性别(雄性或雌性)和出生年份(2016年或2017年)对各种胴体和肉质特性的影响。舍饲羔羊的体型(CS)和肥度(FS)得分较高,且肉的和值高于两个牧场组,这可能是由于脂肪含量较高,而燕麦牧场羔羊的肉最嫩。单胎出生的羔羊CS、FS和胸最长肌横截面积较高,而雌性羔羊的皮下脂肪和非胴体脂肪沉积高于雄性。单胎出生的羔羊和2016年出生的羔羊的肉和值均高于其对应组。总之,如果更喜欢瘦肉和/或肉类产品,基于牧场的饲养系统比舍饲系统更适合卡拉卡贝美利奴羔羊。然而,同样不能忽视的是,在同一时期,舍饲羔羊在体型和肥度方面表现出更好的育肥性能。
