摘 要：
通过对三系配套的兴黔肉鸡及其母系黔Ⅱ和父系Ｈ各１０２只进行重复试验，比较其生产和肉质性能，结果表明，兴黔肉鸡７０日龄平均体重１８００ｇ，比黔Ⅱ高２４１％，低Ｈ系８４％。经统计检验，兴黔肉鸡显著高于黔Ⅱ（Ｐ＜００５），而与Ｈ系差异不显著（Ｐ＞００５）。料肉比２５６，比黔Ⅱ低７９％，比Ｈ系高２２％。全净膛率６９９％，胸腿肌率３９７％，净肉率优于母系。胸肌纤维直径３３４μｍ，保水率６１７５％，肌肉嫩度优于父系。各种必需氨基酸含量在亲本间或高于亲本最大值。表明兴黔肉鸡保持父系生长快和母系肉质优良的特点。

摘 要：
Xingqian broiler produced in tripleline combination
with its maternal line Qian and paternal line H(they were 102 each respectively) was repeatedly
tested. The performance traits of Xingqian broiler were illustrated as follows: the mean body
weight at 70 days old was 1800 g and it was 24.1% higher than Qian (the difference was
significant, P <005) but 8.4% lower than line H (the difference was insignificant, P >005);the
food conversion ratio was 2.56, 7.9% lower than Qian , but 2.2% higher than line H; the drawn
poultry was 69.9%; breastleg muscles percentage was 37.9%; the fiber diameter of breast
muscle was 33.4 m;the water conservation percentage was 61.75%;the meat percentage was
better than its maternal line and the tenderness of muscle better than its paternal line; the
contents of various required aminoacids were between both parents or superior to maximum of
its parents.The results indicated that Xingqian broiler still kept possession of excellent meat
quality originated from maternal line and acquired the advantage of growing fast inherited form
paternal line.
