摘要
首次利用月产蛋模型来研究丝羽乌骨鸡的早期产蛋性能,得出其月产蛋模型方程:Y=-292.2505+611.2779(t/11)-384.0650(t/11)2+164.8722ln(11/t)-24.9171ln2(11/t),其R2=0.9650。月产蛋模型拟合分析结果表明:该模型能很好地拟合丝羽乌骨鸡的早期产蛋规律,对预测丝羽乌骨鸡的产蛋性能具有重要意义。
This study is the first report about the monthly model to study early laying performance of Silkies,we can obtain t he following equation:Y=-292.2505+611.2779(t/11)-38 4.0650(t/11) 2 +164.8722ln(11/t)-24.9171ln 2 (11/t),R 2 =0.9650.The results show that the model can simulate the rule of Sil kies's early laying performance very well.It is very important for calculate t he laying performance of the whole cycle.
