Abstract excerpt
Bivariate analyses of functional longevity in dairy cattle measured as survival to next lactation (SURV) with milk yield and fertility traits were carried out. A sequential threshold-linear censored model was implemented for the analyses of SURV. Records on 96,642 lactations from 41,170 cows were used to estimate genetic parameters, using animal models, for longevity, 305 d-standardized milk production (MY305),...
