Abstract

Observations from 3,032 piglets born between 1984 and 1987 were used to study the effect of litter size at birth on mortality up to 21 days of age, estimated by polynomial regression analysis. A high number of stillborns was observed in litters with fewer and more piglets than the optimum of 9. The number of born piglets had a positive linear effect on mortality, with 0.026 additional deaths per additional piglet in the litter.
