| 摘 要： | 观察207只马岗鹅种母鹅35周间的就巢情况及产蛋量，结果：平均就巢次数为4.2次，个体次平均就巢天数为22.3天，个体就巢天数为94.8天，表现出较强的就巢性；另外，就巢总天数与产蛋量间呈现中等负相关。个体间就巢性差异很大，可望通过选育提高产蛋量。

| Abstract: | Magang Geese(207 , 42 ) were used as experimental materials in this paper. Within 35 WKs experiment, the results showed that the average number of broodiness was 4. 2, the average period of broodiness for each time was 22. 3 days, the average total time of broodiness was 94. 8 days, and Magang Geese showed very strong broodiness. In addition, the number of broodiness for individuals had no significant impact on the egg production, but the loud time of broodiness for individuals had a significant and medium to high coefficient of correlation to egg production. The egg production trait would be able to upgrade due to the remarkable broodiness differences between individuals in Magang Geese. |
