摘要
本试验使用三种不同的高产粉壳蛋鸡品种总计4500只,每个品种1500只,分为3组,置于同一条件下饲养,结果表明,大午金凤蛋鸡育雏育成期生长速度前快后慢,16周龄体重大午金凤为1342.2 g,与其他品种1具有显著差异(P<0.05),与其他品种2具有极显著差异(P<0.01);大午金凤开产初期产蛋率增长迅速,峰值较高;三个品种蛋的品质比较发现,大午金凤43周龄平均蛋重较小,为59.1 g,分别与其他品种1和其他品种2相比具有显著差异(P<0.05)和极显著差异(P<0.01);蛋壳颜色比较结果表明,大午金凤蛋壳颜色a值较大,与其他两个品种相比具有显著差异,颜色更偏红,证实了客户对大午金凤蛋壳颜色认可的反馈。
In this study,we selected 4500 high-yield light-brown shell layers come from three varieties, which divided into 3 groups, 1500 layers every varieties. They were raising in the same henhouse. The results showed that Dawu JinFen layers growing faster than the other 2 varieties layers amongst the 0~7 weeks, but the growth rate slower after the 7 th week, and had the lightest weight of the3 varieties layers at the 16 th week. The average weight mean of Dawu JinFen was significantly(P<0.05)lighter than the other variety 1, and P<0.01 liken to the other variety 2. The laying rate of Dawu JinFen layers was growing fast of the early laying period, and had the highest peak value. The comparison of egg quality amongst the 3 varieties layers showed the Dawu JinFen layers had the lightest egg weight in the43 rd week(59.1 g), significantly difference liken to the other 2 varieties layers(P<0.05 and P<0.01). The comparison of egg shell color showed that Dawu JinFen layers had the largest b mean liken to the other2 varieties layers(P<0.05), affirmed the eggshell color of Dawu JinFen is inclined to be red.
