摘要: Abstract The objectives of this study were to estimate the heritability locomotion score and genetic phenotypic correlations with milk production (150-day milk), body condition (BCS), selected conformation traits. Data collected from 26 herds that visited in October December 1997. During those two visits all lactating cows assigned scores for BCS. Locomotion was scored on a scale 1 (excellent) 5 (severely lame). consisted 5774 records 3298 cows. low. 150-day traits BCS had moderate negative locomotion. Cows higher genetically better high feet legs, foot angle, rear leg set. Udder favorable legs score, steeper straighter also significant udder attachments, longer front attachment, increased quality more
