Effect of type traits on functional longevity of Czech Holstein cows estimated from a Cox proportional hazards model
Original language description
Phenotypic relationships between conformation traits and functional longevity in Holstein cows were evaluated using survival analysis. The data set consisted of 116 369 Holstein cows first calved from 2003 to 2008. Analyses were done separately for twenty linear descriptive type traits, 6 composite traits and height at sacrum measured in centimeters. The strongest relationship between a composite trait and functional longevity was for dairy form, followed by udder and final score. Among the descriptivetype traits, the strongest relationships with longevity were for body condition score (BCS), angularity, traits related to udder attachment and udder depth. Foot and leg traits showed lower impact on functional longevity, and the effect of foot angle wasminimal. Functional longevity declined with decreased BCS of cows. For dairy form and angularity, cows classified as very good were the worst with respect to longevity; while cows classified as poor had the best.
