title: Fraternity size and swine reproduction. II. Genetical consequences.
abstract: A model for swine fecundity that includes the effect of fraternity size is given. Over a range of plausible values for the parameters of the model, the dam-daughter correlation for number born tended to be negative. Thus, selection of replacement gilts born and reared in large litters would not bring about desirable genetic changes in litter size.
