摘要
本试验通过对不同品种鹅种蛋在孵化过程中的失重及孵化效果进行研究。结果表明,种蛋1 d^28 d平均失重率以莱茵鹅最高,与豁鹅、籽鹅比较差异显著(p<0.05),而豁鹅与籽鹅比较,差异不显著(p>0.05)。受精率以莱茵鹅最高,与豁鹅比较差异达到了显著水平(p<0.05),与籽鹅比差异极显著(p<0.01)。受精孵化率籽鹅与豁鹅、莱茵鹅比较,差异分别达到了极显著水平(p<0.01)和显著水平(p<0.05)。入孵蛋重与28d胚蛋重呈强正相关,失重率随蛋重增加而降低;蛋重越大,初生重也随之增大。
In order to discover weight loss of goose egg and hatching results during incubation, three breeds of geese were involved. The results showed that the average weight loss of Rhine Geese was higher than that of Zi Geese and Huo Geese（p〈0.05） in 28 days,but it was not significant beween ZiGeese and HuoGeese（p〈 0.05）. The Rhines fertilization rate was the highest （p〈 0. 05）, the ZiGeeses fertilization hatchability rate was the highest（p〈0.05）. Egg weight was positively correlated with that in 28th day. Percentage of weight loss decreased,while egg hatching weight increased. The bigger the egg weight was, the bigger the birth weight.
