Genetic correlations between longevity and conformation traits in the Czech Holstein population

Popis výsledku v původním jazyce

Genetic relationship between longevity and conformation traits were estimated using data on 57 000 Czech Holstein cows. Longevity traits considered were length of productive life and number of lactations initiated and their functional equivalents (i. e.corrected for milk production). The heritabilities were in the range from 0.05 (locomotion) to 0.43 (height at sacrum). Positive genetic correlations occurred between composition traits feet and legs (0.19) or udder (0.10) and longevity. Body condition score (0.30) and angularity showed stronger genetic correlations with functional longevity. Rear legs set (side view) hock quality (0.19) ranked to the traits with stronger relationship to longevity. Stronger genetic correlations were found between rear udder width and functional longevity and between central ligament and number of lactations. A significant quadratic relationship between conformation and longevity traits did exist.
