贵妃鸡蛋重和繁殖率关系探讨

The relationship between egg weight and reproduction rate of Guifei fowl variety

选用28～29周龄贵妃鸡新产种蛋，按蛋重分4组作登重和繁殖率关系试验，结果表明：蛋重41～45克组受精率、孵化率和健雏率分别达98.11％，94．23％和97．96％，极显著高于蛋重30克和31～35克组。45克内蛋重与三率呈强正相关。小于30克重组三率极显著低于其它组（P＜0.01），试验说明贵妃鸡种蛋最佳蛋重为41～45克，小于30克的蛋不宜作种用。

The eggs of Guifei fowl variety at the ageof 28 or 29 weeks were selected and divided into 4groups (A B C D) according to the egg weight, and acontrol group.The relateouship between the eggweight and the reproduction rate, hatchability and per-centage of healthy day-old chicks were detected. Theresult of the further determination of acquired data in-dicated that in the group (41~45g) those three ratesreached 98.11 N, 94.23% and 97. 96%, respectively,which was ectremely significantly higher than group A(30g). When the egg weight was less than 45g, theheavier thc egg weight was the higher the three rateswere, and their correlation was significantly positive.In the group A the three rates were 83.78%, 58. 06%and 83.33 %, respectively, which was extremely sig-wificautly lower than the other groups (P <0. 01 ).Therefore, the best egg weight of Guifei fowl varietywas 41~45g and the eggs less than 30g could not beused for hatch.
