Genetic parameters for claw disorders in Dutch dairy cattle and correlations with conformation traits.
Impaired claw health is one of the major problems causing production loss and reduced animal welfare in dairy cattle. In response, the Dutch Animal Health Service (GD) Ltd. initiated this study, inExpand
Prevalence, prediction and risk factors of enteropathogens in normal and non-normal faeces of young Dutch dairy calves
Abstract Between January and April 2007, 424 calves under 22 days of age from 108 Dutch dairy herds were sampled to estimate the prevalence of non-normal faecesExpand
Herd- and cow-level prevalence of digital dermatitis in the Netherlands and associated risk factors.
The objective of this cross-sectional study was to reevaluate the prevalence of digital dermatitis (DD) and associated risk factors in The Netherlands. Between May 2002 and December 2003, informationExpand
[Outbreak of bovine virus diarrhea on Dutch dairy farms induced by a bovine herpesvirus 1 marker vaccine contaminated with bovine virus diarrhea virus type 2].
On 23 February 1999, the Dutch Animal Health Service advised all Dutch veterinary practices to postpone vaccination against bovine herpesvirus 1 (BHV1) immediately. The day before severe diseaseExpand
Clinical course of digital dermatitis lesions in an endemically infected herd without preventive herd strategies.
Lactating Holstein-Friesian dairy cows in four separately housed groups in a herd with endemic digital dermatitis (DD) were monitored weekly for 4 weeks in December 2004 for the presence of andExpand
Effects of different intervention strategies on the incidence of papillomatous digital dermatitis in dairy cows
The effects of four different intervention strategies on the incidence of severe lesions of digital dermatitis in an experimental dairy herd were compared with the effects of a control strategyExpand
Intra-class correlation attributable to claw trimmers scoring common hind-claw disorders in Dutch dairy herds.
Data of a cross-sectional study on prevalence of seven common bovine-claw disorders were used to calculate the intra-class correlation coefficients (ICCs) for claw trimmers. Fifteen professional clawExpand
[Diarrhea and loss of production on Dutch dairy farms caused by the Schmallenberg virus].
At the end of August and the first two weeks of September 2011 dozens of veterinary practitioners reported to GD Veekijker (Animal Health Service) several dairy herds with cows with sudden decreasedExpand
Lungworm outbreaks in adult dairy cows: estimating economic losses and lessons to be learned
Two lungworm outbreaks in dairy herds were investigated in order to estimate the resulting economic costs. On the two farms, with 110 and 95 cows, total costs were estimated at €159 and €167 per cow,Expand
The dynamics of digital dermatitis in populations of dairy cattle: model-based estimates of transition rates and implications for control.
Five groups of dairy cows affected by digital dermatitis were subjected to five different footbath strategies and evaluated at regular 3-weekly intervals. A standard protocol was used to record fiveExpand
