Abstract
The estimates of heritability of total teat number obtained in a population of Minnesota No. 1 swine were 0.10±0.04 from the dam-offspring regression analysis and 0.23±0.20 from the paternal half-sib correlation. The regressions of various maternal traits on total teat number were small and statistically non-significant for the traits considered. Significant regression values of 0.27 and 11.70 were found for the regression of number of pigs weaned and pounds of pig weaned on functional teat number after removing the effect of number of pigs born alive.
