Abstract

 

The polymorphism of serum esterase (Es) of Henan Yuxi fat-tailed sheep was detected through polyacrylamide gel electrophoresis (PAGE), and the correlation between serum esterase and productivity was analyzed. The research result indicated that there are two alleles on the Es loci of Henan Yuxi fat-tailed sheep: Es+ and Es-. The gene frequencies of Es+ and Es- were 0.55 and 0.45, respectively. Besides, the frequencies of three genotypes (Es++, Es+- and Es--) are 0.425, 0.250 and 0.325, respectively. The recommended height of Es++ genotype is significantly higher than that of Es+- genotype (P<0.05), but the above two produce indistinctive difference in recommended height with Es-- genotype (P>0.05). The chest circumference of Es++ genotype is significantly higher than that of Es-- (P<0.05), but the above two produce indistinctive difference in chest circumference with Es+- genotype (P>0.05). Es exerts no significant impact on other indexes (P>0.05).

 

Key words: Henan Yuxi fat-tailed sheep, serum esterase (Es), polymorphism.

Abbreviation
