Analysis of the phenotypic relationships between type traits and functional survival in Czech Fleckvieh cows

Popis výsledku v původním jazyce

The phenotypic relationships between type traits and functional survival were analyzed in 47 786 Czech Fleckvieh cows first calved from 1994 to 2003. Survival analysis was employed. Rump angle, body depth, rear legs side view and pastern, fore udder length, rear udder attachment, and teats traits exhibited an intermediate optimum. Height at the sacrum, muscularity, rump length, and rump width, hock, and hoof angle, central ligament, and udder depth tended toward a linear relationship to functional survival. Body measurement traits showed an almost linear relationship concerning longevity except for chest girth, which exhibited an intermediate optimum. Larger, broader, muscular cows had a higher risk of being culled compared with smaller cows. Foot andleg traits had an important influence on functional longevity, especially rear legs side view and pastern. Among udder traits, fore udder length, rear udder attachment, and front teat placement showed a high impact on cows´ longevity.
