二郎山山地鸡不同产蛋阶段对种蛋孵化效果的影响

为研究不同产蛋阶段对种蛋孵化效果的影响,实验选取二郎山山地鸡种鸡群4个不同产蛋阶段,分别收集种蛋孵化,测定孵化效果。结果表明:不同产蛋阶段的种蛋与其受精率、受精蛋孵化率和健雏率都有着密切的关系。以32周龄种蛋孵化效果最优,40周龄次之,再次为25周龄,最差为48周龄。研究结果表明产蛋阶段对种蛋孵化效果有重要的影响。

The Effects of Different Stages of Egg Production on Broiler Hatching Egg Characteristics in Erlang Mountainous Chicken

To study the effects of different stages of egg production on hatching egg characteristics,the hatching egg at 4 different stages of Erlang Mountainous Chicken were collected and hatched,then determined the hatching results.The results suggested that the hatching egg at different stages may be related with their fertilization rate,hatching rate and healthy rate.There were the best results in the 32 weeks,followed by the 40 weeks,then the 25 weeks,and the 48 weeks were the worst.The analysis results suggested that the different egg production have an important effect on hatching egg characteristics.
