不同产蛋时间扬州鹅种蛋孵化成绩比较

Analysis on hatching performance of Yangzhou goose breeders in different years and laying time

[目的]研究扬州鹅种鹅在不同年份、产蛋时间内孵化成绩逐月变化趋势,了解扬州鹅不同年份、产蛋时间种蛋受精孵化变化情况,提高种鹅生产效率。[方法]以扬州鹅繁殖群种鹅生产的种蛋为试验材料,收集整理2018年9月—2020年4月扬州鹅孵化成绩资料,比较种鹅产蛋期内不同产蛋时间其连续变化总体趋势。[结果]每年的9月和10月以及第2年4月的受精率和孵化率均要低于其他月份。[结论]在每年的9月和10月以及第2年的4月要加强营养,注重饲养管理,以提高孵化成绩。

[Objectives]The purpose of this paper is to study the monthly change trend of hatching performance of Yangzhou goose breeders in different years and laying time,and to understand the fertilization and hatching changes of Yangzhou goose breeding eggs and improve the production efficiency of breeding goose.[Methods]Taking the eggs produced by Yangzhou geese breeding group as experimental materials,the hatching performance data of Yangzhou geese from September 2018 to April 2020 were collected and sorted out,and the overall trend of continuous changes in different laying time of Yangzhou geese was compared.[Results]Both fertilization rate and hatching rate were lower in September and October of each year and in April of the following year than in other months.[Conclusions]Therefore,nutrition should be strengthened in September and October of each year and in April of the following year,and feeding management should be paid attention to in order to improve hatching performance.
