In this study, meat quality traits and fatty acid compositions of Hair Goat and Saanen Hair Goat ( ) crossbred kids fattened under intensive, semi-intensive and extensive conditions were determined. For meat quality traits, differences in , , drip loss, water holding capacity, cooking loss and Warner-Bratzler peak shear force values of the experimental groups were not found to be significant. According to colour measurements at the 0th and 45th minute, the extensive fattening group of Hair Goat kids had greater lightness ( ) values and the intensive fattening group of Hair Goat kids had greater redness ( ) values. For intensive, semi-intensive and extensive fattening groups of Hair Goat kids, total saturated fatty acid contents of longissimus dorsi (LD) muscle samples were respectively measured as 19.28 %, 23.75 % and 23.35 %. Total monounsaturated fatty acid contents were respectively measured as 67.30 %, 66.22 % and 65.72 %. Total polyunsaturated fatty acid contents were respectively measured as 5.46 %, 3.06 % and 3.16 % and conjugate linoleic acid contents were respectively measured as 0.48 %, 0.55 % and 0.65 %. For intensive, semi-intensive and extensive fattening groups of Saanen Hair Goat ( ) kids, total saturated fatty acid contents of LD muscle samples were respectively measured as 21.01 %; 21.98 %, 19.10 %; total monounsaturated fatty acid contents were respectively measured as 64.04 %, 64.33 %, 52.44 %. Total polyunsaturated fatty acid contents were respectively measured as 3.53 %, 4.89 % and 4.84 % and conjugate linoleic acid contents were respectively measured as 0.52 %, 0.58 % and 0.73 %. It was concluded that the extensive fattening group had greater conjugated linoleic acid contents than the other fattening groups.
本研究测定了在集约化、半集约化和粗放式饲养条件下育肥的黑山羊和萨能黑山羊杂交羔羊的肉质性状和脂肪酸组成。对于肉质性状，未发现各实验组在pH值、酸碱度、滴水损失、持水能力、烹饪损失和沃纳-布拉茨勒剪切力峰值等方面存在显著差异。根据第0分钟和第45分钟的颜色测定，黑山羊羔羊的粗放育肥组具有更高的亮度（L*）值，而黑山羊羔羊的集约育肥组具有更高的红色度（a*）值。对于黑山羊羔羊的集约、半集约和粗放育肥组，背最长肌（LD）肌肉样本的总饱和脂肪酸含量分别测定为19.28%、23.75%和23.35%。总单不饱和脂肪酸含量分别测定为67.30%、66.22%和65.72%。总多不饱和脂肪酸含量分别测定为5.46%、3.06%和3.16%，共轭亚油酸含量分别测定为0.48%、0.55%和0.65%。对于萨能黑山羊杂交羔羊的集约、半集约和粗放育肥组，LD肌肉样本的总饱和脂肪酸含量分别测定为21.01%、21.98%、19.10%；总单不饱和脂肪酸含量分别测定为64.04%、64.33%、52.44%。总多不饱和脂肪酸含量分别测定为3.53%、4.89%和4.84%，共轭亚油酸含量分别测定为0.52%、0.58%和0.73%。得出的结论是，粗放育肥组的共轭亚油酸含量高于其他育肥组。
