Herd Level Risk Factors for Non-infectious and Infectious causes of Lameness for Ontario Dairy Herds

摘要

Lameness is one of the most important issues facing the dairy industry, both in terms of production costs and pubHc perception of dairy cow welfare. To assist bovine practitioners in making recommendations that reduce or prevent lameness, there is a need for knowledge about the prevalence of lameness and a more complete understanding of the factors that contribute to lameness in different North American management systems. The objective of this project was to determine the effect of selected risk factors on the prevalence of infectious and non-infectious claw lesions on dairy farms in Ontario.
