| 摘 要： | 选用1日龄北京油鸡公雏360只,随机分成5个处理,每个处理6个重复,每个重复12只鸡,饲喂玉米豆粕型饲料基础日粮,添加0、0.25%、0.5%、1%、2%共轭亚油酸(CLA),用以研究CLA对北京油鸡脂类代谢和肉质性状的长期影响,试验期18周。结果表明:饲粮CLA提高了饲料利用率(P<0.05),显著性地降低了北京油鸡腹脂率和血清中脂蛋白脂酶(LPL)、leptin,显著增加了肌内脂肪的含量(P<0.05),但对pH值和肉色无显著性影响(P>0.05)。

| Abstract: | An experiment was carried out to evaluate long term effect of the dietary conjugated Linoleic acid(CLA)on meat quality,productive traits and on carcass yields of birds.360 males of Beijingyou chicks were randomly divided into 5 groups,received from 1d to slaughtering age(126 d)a basal diet supplemented with 0.25 %,0.5 %,1 % and 2 % CLA preparation containing 80 % CLA isomers respectively.CLA supplementation did not influence growth performance(P >0.05)with a trend to decrease body weight and increase feed conversion,and carcass characteristics(P > 0.05),but reduced abdominal fat at 126 days old(P < 0.01).CLA decreased lipoprotein lipase(LPL)activity in serum(P < 0.05).Significant differences were found among groups in intramuscular fat(P < 0.05)with a trend to decrease leptin(P < 0.05)in serum,but no difference in meat color and pH value(P > 0.05). |
