苏淮猪肌内脂肪表型测定及其与IGF2和SCD基因的多态性关联性分析
Analysis of intramuscular fat content in Suhuai pigs and its correlation with polymorphisms of IGF2 and SCD genes
摘要
Abstract
The aim of the present research was to evaluate the intramuscular fat (IMF) content in Suhuai pigs and to select suitable molecular markers for improving the IMF content in the animals.A total of 314 Suhuai pigs were used for IMF content measurement,and the polymorphisms of IGF2 and SCD genes in the pigs were assayed using the method of iMLDRTM.As a result,the IMF content in Suhuai pigs was (1.99±0.04)％,and the coefficient of variation was 37.13％.Within this population,the IMF content in the barrows seems higher than in the sows,but the difference was not significant.As for IGF2,the frequencies of its alleges A and G were 0.403 and 0.597,respectively.The frequencies of its genotypes AA,AG and GG were 0.175,0.455 and 0.370,respectively,but there were no significant differences in the IMF content among the three genotypes.In terms of SCD,the frequencies of its alleles C and T were 0.417 and 0.583,respectively.The frequencies of its genotypes CC,CT and TT were 0.169,0.497 and 0.334,respectively,with no significant differences in the IMF content among these genotypes,either.Moreover,there were no significant differences in the IMF content among the combined genotypes between IGF2 and SCD.These results indicated that IGF2 and SCD had no correlation with IMF content in Suhuai pigs,and these genes could not serve as markers for improving the IMF content in Suhuai pigs.关键词
