| 摘要: |
| 在两种营养水平下,较系统地测定了略阳鸡及其杂种的肉用性能与胴体品质。结果表明:(1)白羽和黑羽略阳鸡10周龄体重分别为923.0g和783.3g,料肉比分别为2.83和3.07;(2)它们的杂种一代10周龄平均体重分别提高了82.61%和97.47%,料肉比分别降低了14.84%和18.73%;(3)略阳鸡的胸肉率和腹脂率均显著低于其杂种及AA鸡(P<0.05)。几种试验鸡的全净膛率和腿肉率没有明显差异(P>0.05);(4)略阳鸡肉中蛋白质含量明显高于其杂种及AA鸡,而脂肪含量却较低(P<0.05)。 |

| Abstract: |
| The meat performance and carcass quality of Lueyang Chickens (LC) and their first filial generations (F1 were systematically determined under two nutrition levels. The results showed that. (1) 10-wks body weight (BW) was 923.Og and 783.3g, and feed consumption -to body weight (FCBW) was 2.83 and 3.07 resp.for White Lueyang Chickens(WLC)and Black Lfieyang Chickens (B'LC). (2) For Fj of WLC and BLC, 10-wks BW increased by 82.61% and 97.47%, and FCBW decreased by 14.84% and 18.73% resp. (3) Breast meat percentage and abdominal fat percentage of LC were significantly lower than their crosses and AA(P<0.05).But dressing percentage and legs meat percentage had no difference among all experimental birds(P>0.05). (4)Protein percentage in meat of LC was higher (P<0.05) >but fat percentage in meat was lower (P<0.05) when compared with AA and their crosses. |
