    Abstract

    The influence of uterine crowding on litter size and the fetal capacity of the feral pig uterus were examined in a control (C) group and three groups of surgically altered feral (Ossabaw) gilts. The altered groups were unilaterally ovariectomized (UOX), unilaterally tubally ligated (UTL), or unilaterally hysterectomized-ovariectomized (UHOX). Litter sizes of C, UOX and UHOX at 30 days of gestation were similar and larger than the UTL group. At 45 days, litter size was reduced (P less than 0.06) in UHOX gilts. These results indicate that uterine capacity of feral swine is limiting after Day 30, and that the maximum litter size for the feral pig is 8 to 10.
