Supplementary material for: Invited review: Risk factors for transition period disease in intensive grazing and housed dairy cattle Daros, Ruan; Weary, Daniel; von Keyserlingk, Marina


Dairy cows in both grazing and zero-grazing systems are at risk of disease in the weeks around calving. In this review, we highlight the factors associated with the development of diseases common during this period and discuss how different production systems face different challenges in improving cow health; some risks (including some associated with lameness) appear easier to address in grazing systems, but some nutritional issues are easier to manage in zero-grazing systems. We conclude that system specific solutions are required. In the supplementary material you will find a list of the research compiled to estimate the disease prevalence of dairy cattle under grazing and zero-grazing dairies.
