非洲鸵鸟繁殖性能指标相关性分析

以陕西英考鸵鸟股份有限公司官池鸵鸟繁育中心101只鸵鸟连续3 a繁殖记录为材料,分析部分繁殖性能指标间的相关关系。结果表明:鸵鸟的年产蛋数与入孵蛋数、出雏数、受精率、孵化率呈正相关,相关系数分别是0.1501、0.1342、0.0111、0.1268(p<0.05);入孵蛋数与出雏数、受精率、孵化率呈正相关,相关系数分别为0.1278、0.0194、0.1187(p<0.05);出雏数与受精率、孵化率呈现正相关,相关系数为0.2755、0.2 422(p<0.01),与蛋重相关,但差异不显著(p>0.05);受精率与孵化率呈现正相关,相关系数为0.2978(p<0.01)。孵化率与蛋重呈现正相关,相关系数为0.2978(p<0.01)。

The Correlation Analysis on the Reproductive Performance of Ostriches

The part correlation among reproductive performance of ostriches in Guanchi ostrich reproduction center of Shaanxi Yingkao Ostrich Co Ltd.was studied according to the annual egg production in recent 3 years.The result showed that the annual egg production is in positive proportion to the number of the eggs hatched,litter size,fertility rate and hatchability of fertile eggs.Their relevant coefficients are 0.1501,0.1342,0.0111,0.1268(p<0.05) respectively.The number of the eggs hatched is in positive proportion to litter size,fertility rate and hatchability.The relevant coefficients is 0.1278,0.0194,0.1187(p<0.05) respectively.The litter size is in positive proportion to fertility rate and hatchability.Their relevant coefficients respectively is 0.2755,0.2422(p<0.01).Fertility rate is in positive proportion to hatchability of fertile eggs.Its relevant coefficients is 0.2978(p<0.01);The hatchability is in positive proportion to egg size.Its relevant coefficients is 0.2978(p<0.01).The annual egg production,litter size,fertility rate are also is in positive proportion to egg size,but its difference is not striking(p>0.05).
