塔额盆地生态环境对北京油鸡生产性能的影响

Effects of Ecological Environment on Growth Performance of Beijing You Chicken in Ta'er Basin

为了研究塔额盆地气候条件对北京油鸡生态养殖生产性能的影响,引进同批次的商品代北京油鸡经过脱温饲养6周龄后,分别利用牛舍(Y1组)和简易棚(Y2组)作为生态养殖的两种不同饲养方式进行生产性能指标的对比试验,以每组饲养量3000只分别转入YI和Y2鸡舍作为地面放养的试验鸡群,对鸡舍内、外部的气温、风速指标进行检测,测定鸡群生产性能及抗体水平。结果显示,Y1、Y2组与饲养标准经显著性比较,毛重、净膛体重、出肉率等指标均差异显著(P<0.05),试验组生产性能指标未达到饲养标准的水平,但Y1、Y2组差异显著(P<0.05),Y1组的生产性能指标优于Y2组,表明北京油鸡生态养殖与塔额盆地生态环境变化有很大的相关性。

In order to understand the effects of ecological environment on Beijing You chicken in Ta＇er basin,the same batch of 6000 Beijing You chichen were divided averagely into two groups after 6-week removal of temperature raising.One group was in cowhouse（Y1）,the other was in shed（Y2）.Through clinical observation and antibody level tests,the research compared the temperature,wind speed,and other environmental indexes among the outside world,Y1 and Y2,and found that there were significant difference in mean scores of gross weight,net weight,dressing percentage among Y1,Y2 and the breed standard（P＜0.05）.The growth performance of Y1 is better than Y2,although the two didn＇t reach the breed standard level.In short,there was a significant correlation between growth performance of Beijing You chicken and change of ecological environment in Ta＇er basin.
