| 摘 要： | 过去,我国农村蛋鸭饲养普遍采用传统的圈牧相结合的方式,亦即圈养舍饲与放牧饲养并举,近年来,由于天然牧场及自然资源的减少,同时随着养鸭业的大规模发展,不放牧的密集圈养已逐渐成为养鸭业的主要饲养方式。

| Abstract: | The performance and egg quality under different feeding methods of Jinding ducks are compared. The body weights of enclosure-fed ducks arc significantly larger than those of pasture supplemented feeding. But the age of sexual maturity, egg production, egg weight, egg shape and yolk color are obviously better for the latter group. There is no obvious difference for the percentage of shell in total egg weight and the Haugh unit between the two groups. |
