Bovine Claw and Limb Disorders at Claw Trimming Related to Milk Yield [PDF]

Journal of Dairy Science, 2007
As part of a cross-sectional study of Norwegian Red Cattle, associations of lameness, lesions at the tarsus, claw shapes, claw lesions, and claw trimming with milk yield were examined. Fifty-five tie-stall herds and 57 free-stall herds were sampled by computerized systematic selection, and 2,665 cows were trimmed and limb and claw disorders recorded ...

Prevalence of Claw Disorders in Dutch Dairy Cows Exposed to Several Floor Systems [PDF]

Journal of Dairy Science, 2003
Claw health was examined in an observational study on Dutch dairy farms with either a slatted floor (SL), slatted floor with manure scraper (SL-SCR), solid concrete floor (SCF), a straw yard (SY), or a zero-grazing feeding system (ZG). Hooves of cows' hind legs were examined for the presence and severity of claw disorders during hoof trimming events at

Genome-wide association study for claw disorders and trimming status in dairy cattle [PDF]

Journal of Dairy Science, 2015
Performing a genome-wide association study (GWAS) might add to a better understanding of the development of claw disorders and the need for trimming. Therefore, the aim of the current study was to perform a GWAS on claw disorders and trimming status and to validate the results for claw disorders based on an independent data set.

Prevalence of claw disorders in swiss cattle farms

Schweiz Arch Tierheilkd, 2021
The project «Healthy claws - the foundation for the future» aims to establish a Swiss national claw health monitoring based on digital recordings by claw trimmers during claw trimming. To assess claw health on the participating farms, between-herd prevalence, within-herd prevalence and cow prevalence of all claw disorders based on the «ICAR Claw Health
