Summary and Conclusions: These data are in general agreement with those found with other mammalian species. Maternal effects for weights were demonstrated with these data and have also been reported in other work with mice and rats; however, maternal effects have been lacking in studies with swine. Heterosis was evident for weights at 21 and 45 days, but was not present for litter size. General combining ability and sex linked effects were highly significant for weights but not for litter size. There was no evidence of an interaction between maternal effects and mating systems.
