摘要
在正常的孵化条件下,测定了迪卡鸡种蛋在孵化期间的失重率,通过系统分析种蛋的失重规律及失重与孵化效果的关系表明:种蛋的失重遵循快——慢——快的规律,且失重过大和过小均影响胚胎的正常发育。
The percentage of Dekalb egg weight loss(EWL) during normal incubation and its relationship with hatching results were measured. Statistical analysis indicated that the law of EWL is fast - slow- fast,otherwise the embryo development will be affected badly.
