摘　　要：该研究旨在比较位于北京、河南和广西的三个不同经纬度养殖企业肉鸽繁殖性能的差异,分析不同光照时间、气温等因素对肉鸽繁殖性能的影响。该试验以我国处于不同经纬度的三个肉鸽养殖企业3个完整年的生产数据为研究基础,逐月系统比较分析了肉鸽繁殖性能(月平均产蛋数、受精率)与光照时长和温度变化之间的联系。结果发现,处于较高纬度地区的北京A公司所养殖的肉鸽,平均产蛋数与受精率均与光照时长有显著正相关性(P<0.05),并且随着光照时长的升高,平均产蛋数显著增加(P<0.05),河南B公司的产蛋数、广西C公司的受精率与光照时长均呈显著正相关(P<0.05);北京A公司和广西C公司所饲养的肉鸽,平均产蛋数和受精率均与温度有极显著的正向相关性(P<0.05)。可见,肉鸽繁殖性能与光照时长和温度紧密相关,低纬度地区饲养的肉鸽繁殖性能受光照时长与温度的影响小于高纬度地区。The purpose of this study was to compare the reproductive performance of meat pigeons in three breeding enterprises located in Beijing,Henan and Guangxi with different latitude and longitude,and to analyze the effects of different light duration,temperature and other factors on the reproductive performance of meat pigeons.Based on the production data of three complete years from three meat pigeon breeding enterprises in different latitudes and longitudes in our country,this study systematically compared and analyzed the relationship between the reproductive performance of meat pigeons(monthly average egg number,fertilization rate)and the changes in light duration and temperature by months.The results showed that the average egg production and fertilization rate of meat pigeons raised by Company A in Beijing,located in higher latitudes,were significantly positively correlated with light duration(<0.05),and with the increase of light duration,the average egg production increased significantly(<0.05).The egg production of Company B in Henan and fertilization rate of Company C in Guangxi were significantly positively correlated with light duration(<0.05);The average number of eggs laid and fertilization rate of meat pigeons raised by Company A in Beijing and Company C in Guangxi have a very significant positive correlation with temperature(<0.05).This study found that the reproductive performance of meat pigeons was closely related to light duration and temperature,and the reproductive performance of meat pigeons raised in low latitude area was less affected by light duration and temperature than that in high latitude area.
