A new, partially deficient transferrin variant (TF F) was found in ser
um samples of a wild boar and his offspring from crossing with Pietrai
n sows. Family analyses confirmed its genetic control by a codominant
allele, TF(F). Finding of this new variant has brought the total numbe
r of pig transferrin variants to nine (F, I, A, B, C, X, D', E, D).
