Genetic Relationship between Type Traits, Number of Lactations Initiated, and Lifetime Milk Performance in Czech Fleckvieh Cattle
Popis výsledku v původním jazyce
Genetic relationship was analyzed between type traits and longevity measures in dual-purpose cattle. Data from 91 486 Czech Fleckvieh cows first calved between 2003 and 2009 were used. Longevity was defined as the actual number of lactations initiated per cow and also as functional longevity, which incorporated an adjustment to account for variation in voluntary culling based upon milk production. Lifetime performance was defined as cumulative milk production through the 6th parity. All cows were scored for conformation traits during their first lactation. Genetic correlations between these traits and longevity measures were estimated. We conclude that selection based upon easily and inexpensively measured type traits could improve functional longevity of cows as well as lifetime milk production.
