Association between somatic cell count and serial locomotion score assessments in UK dairy cows.
This research investigated the effect of lameness, measured by locomotion score (LS) on the somatic cell count (SCC) of UK dairy cows. The data set consisted of 11,141 records of SCC and LS collected monthly on 12 occasions from 1,397 cows kept on 7 farms. The data were analyzed to account for the correlation of repeated measures of SCC within cow. Results were controlled for farm of origin, st...
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 کاملThe effect of digital lesions and floor type on locomotion score in Dutch dairy cows.
This study describes the effects of floor system, digital dermatitis (DD) and interdigital dermatitis and heel-horn erosion (IDHE) on locomotion performance in 225 dairy cows of 12 commercial dairy herds. Nine herds were kept in cubicle houses with concrete passageways (either solid, slatted, or grooved concrete) and three herds were kept in straw yards. Animals were at most five times examined...

متن کاملLocomotion Scoring Your Cows: Use and Interpretation
Lameness of dairy cattle is an economic and welfare issue. It is the third most important health related economic loss facing the dairy industry, following fertility and mastitis. Most economic loss due to lameness results from costs of premature culling, veterinary treatment, increased labor, discarded milk, prolonged calving interval, and reduced milk production (Kossaibati and Esslemont, 199...
