New Genetic Variants of Transferrins and Haptoglobins in Pigs

Abstract

POLYMORPHISM of transferrins in pigs was first shown by Ashton1 and Kristjansson2,3. The alleles which control the synthesis of the three protein fractions were designated TfA and TfB. King4 identified another allele TfC in animals of the Landrace breed. In the breeds so far investigated the frequency of this latter is very low5,6, but transferrin C has been recently detected in the homozygous state in some Chinese pigs (Sus vitatus) inbred since 1958 at the Zoological Gardens, Prague6 (Fig. 1).
