摘　　要：为比较雪峰乌骨鸡配套系母本纯系与商品代的生长性能、屠宰性能和肉品质,试验选取1日龄雪峰乌骨鸡配套系母本纯系、商品代各140只(公母各半),采用非线性模型拟合生长曲线并对其生长性能进行比较分析,上市日龄公母各选30只进行屠宰,测定屠宰性能和肉品质。结果显示:雪峰乌骨鸡最适生长曲线模型是Von Bertalanffy,配套系拐点周龄早于纯系,上市体重显著大于纯系,耗料增重比略小于纯系;配套系公鸡的屠宰率、半净膛率、全净膛率、腹脂率显著大于纯系公鸡,母鸡的屠宰率、胸肌率、腿肌率、腹脂率显著大于纯系母鸡;配套系公鸡的滴水损失显著小于纯系公鸡,剪切力、黄度值、肌纤维面积和直径显著大于纯系公鸡,母鸡的滴水损失显著小于纯系母鸡,pH、红度值、肌纤维面积和直径显著大于纯系母鸡;配套系公母鸡的乌度值、灰分、脂肪、蛋白质、总氨基酸含量与纯系公母鸡差异不显著。本研究结果表明,配套系商品代具有更好的生长性能和屠宰性能,在今后育种过程中,可将提高配套系肉质嫩度和降低腹脂率作为育种目标之一。In order to compare the growth performance,slaughter performance and meat quality of Xuefeng black bone chickens from pure line and matching line,280 one-day-old Xuefeng black bone chickens(half male and half female)were selected to compare and analyze their growth performance and calculate the cross-dominance rate.Meanwhile,a nonlinear model was used to fit the growth curve.The slaughtering performance and meat quality of 30 male and 30 female at market age were tested.The results showed as follows:(1)The optimal growth curve model of Xuefeng black bone chickens was Von Bertalanffy,the inflection point age of the commercial line was earlier than that of the pure line,the market weight was significantly(P<0.05)higher than that of the pure line,and the feed to gain ratio was slightly lower than that of the pure line;(2)The slaughtering rate,half evisceration rate,full evisceration rate and abdominal fat rate of commercial line cocks were significantly higher than those of pure line cocks(P<0.05),and the slaughtering rate,breast muscle rate,leg muscle rate and abdominal fat rate of hens were significantly higher than those of pure line hens(P<0.05);(3)The drip loss of commercial line cocks was significantly(P<0.05)less than that of pure line cocks,the shear force,b*,muscle fiber area and diameter were significantly(P<0.05)greater than that of pure line cocks,the drip loss of hens was significantly(P<0.05)less than that of pure line hens,and the pH,a*,muscle fiber area and diameter were significantly(P<0.05)greater than that of pure line hens;(4)The contents of L*,ash,fat,protein and total amino acid of commercial line were not significantly different from those of pure line(P>0.05).The results showed that the commercial lines had better growth performance and slaughter performance than pure line.In the future breeding process,improving the meat tenderness and reducing the abdominal fat percentage of commercial lines could be one of the breeding goals.
