Abstract: | The erythrocyte esterase-D (Es-D) of four European-American pig breeds, two Taiwan native pigs (Taoyuan and Short ear breeds), Philippine native pig and wild boar populations (Sus scrofa riukiuanus) in Japan was investigated by using starch gel electrophoresis. Analysis of parentage records of the pigs revealed that the phenotypic variation of erythrocyte esterase-D was controlled by two codomi-nant alleles Es-DA and Es-DB. The allele Es-Db was mostly found in three European -American pig breeds, Landrace (0.100), Hampshire (0.135) and Duroc (0.102). All of the wild boar populations were monomorphic for allele Es-DA. |
