متن کاملAssociations between hoof lesions and locomotion score in 1098 unsound dairy cows.
To investigate the association between locomotion score and types of hoof lesion, cows from 91 selected dairy herds in southern Chile were studied. The locomotion score was recorded for all of the lactating cows (n=10,699). The mean prevalence of lame cows, when all locomotion scores >1 were included was 33.2% in large herds and 28.7% in small herds. There were 39.7%, 42%, 17.9% and 0.4% cows w...
متن کاملHoof Measurements Related to Locomotion Scores and Claw Disorders in Dairy Primiparous Cows
The aim of the presented study was to estimate the influence of the traits of hoof measurement in dairy cows on claw disorders, lameness, and locomotion scores were determined. Data on claw health and measurement trait of claws were collected from 68 primiparous cows housed in tie stalls and from 76 primiparous cows housed in free stalls. Data were collected during professional claw trimming. T...
