场区绿化情况对种鹅产蛋性能的影响

Effect of Tree Planting in Factory Area on Laying Performance of Breeding Geese

通过对鹅舍前后和运动场内不同绿化情况的4个种鹅场鹅群产蛋性能的对比,发现绿化效果好的鹅场由于在春末和夏初能够为鹅群提供凉爽的生活环境,而使其产蛋期明显延长,而且产蛋数量也显著增加(P<0.05);但是,在春末和夏初种蛋的受精率和孵化率相对较低。在低温季节鹅场绿化情况对鹅群的产蛋量、种蛋受精率和孵化率没有显著影响(P>0.05)。说明降低环境温度是延长鹅群产蛋期和提高产蛋量的有效措施。

Through the comparison of effects of planting trees on breeding geese＇s laying performance in 4 breeding geese farms,it showed that the geese farm of better afforestation could provide cool living environment so that the laying period was prolonged and egg production increased（P0.05）.Meanwhile the fertility rate of hatching egg obviously lowered in late spring and early summer.The effects of degree of greening in geese farm on the egg production,the fertility rate and hatching rate of hatching egg were in-significant in cold seasons（P0.05）.The result shows that the reduction of temperature is an effective action to prolong laying period and increase egg production.
