Abstract
Sow longevity, measured in terms of final parity attained, was analysed by a variety of methods,including survival analysis, linear model and generalised linear mixed model approaches. Heritability estimates ranging from 0.11 to 0.21 were obtained from the different analyses. Non-survival analysis methods did not perform well as alternatives to survival analysis. Evidence of low, unfavourable genetic correlations with average daily gain and ultrasonic backfat depth was found.
