Abstract: Shiqi pigeons are one of the excellent local breeds of meat pigeons in China，known for their superior reproductive performance. This paper aims to elucidate the differences in egg weight，laying intervals，and birthweight among different quarters of Shiqi pigeons across the entire year. In this experiment，data on the laying intervals，egg weight，and birthweight of one⁃day⁃old squab pigeons from 300 pairs of two⁃year⁃old Shiqi pigeons over a complete year were measured and analyzed. The results showed that the laying intervals was the longest in the second and third quarters，with significant differences among all quarters except between the first and second quarters（P<0.05）. The egg weight was the highest in the third quarter and the lowest in the second quarter，with a significant difference between the second and third quarters（P<0.05）. The birthweight of squab pigeons was the greatest in the third quarter and the lowest in the second quarter，and also showed a significant difference between the second and third quarters （P<0.05）. By comparing and analyzing the laying intervals，egg weight，and birthweight of squab pigeons across different quarters throughout the year，we can gain insights into the seasonal reproductive characteristics of Shiqi pigeons. This information can assist breeding enterprises （or households） in better formulating breeding plans， thereby improving production efficiency and economic benefits.

摘要： 石岐鸽是中国优良的肉用地方鸽种之一，具有优越的繁殖性能。该文旨在明确石岐鸽在一年的不同季度蛋重、产蛋间隔和乳鸽初生重的差异。该试验选取一个完整年度300对2年龄石岐鸽的产蛋间隔、蛋重以及1日龄乳鸽初生重数据进行测定分析。结果显示，产蛋间隔在第二季度与第三季度最长，除了第一季度与第二季度无显著差异外，其余季度之间都有显著性差异（P<0.05）；蛋重在第三季度最大，第二季度最小，第二季度与第三季度有显著性差异（P<0.05）；乳鸽初生重在第三季度最大，第二季度最小，第二季度与第三季度有显著性差异（P<0.05）。通过比较分析全年不同季节的产蛋间隔、蛋重和乳鸽初生重指标，可以了解石岐鸽的季节繁殖特性，帮助养殖企业（户）更好地制定养殖规划，提高生产效率和经济效益。
