| 摘 要： | 对 2 3 6只 3 0周龄初产马岗鹅母鹅进行个体观察记录 ,结果表明 :第 1个产蛋年 ,产蛋 3 4周累计产蛋 90 91枚 ,平均每只母鹅产蛋 3 8.52枚 ,个体母鹅最高产蛋达 78枚 ,最少只有 7枚。马岗鹅就巢性强 ,繁殖性能低。但由于个体之间就巢性存在较大差异 ,预示可通过选种降低种鹅就巢性 ,提高产蛋量

| Abstract: | This paper reported an observation made of 236 female Magang geese aged 30 weeks. The egg yield in the first laying year totaled 9091 eggs, averaging 38.52 per each, and reaching the maximum of 78 and the minimum of 7 for certain individual goose. The main cause for the low propagation of Magang geese, the authors argued, lied in the straining of the nest stickiness. However, wide variation existed between the individual geese, which promised the prospect of improvement in egg yield by means of selective breeding to weaken the nest stickiness. |
