The economic impact of bovine viral diarrhoea on Dutch and Chinese dairy farms
Bovine viral diarrhoea (BVD) is an endemic disease in most cattle-producing countries throughout the world and causes significant economic losses. Economic losses are a result of symptoms including diarrhoea, abortion, premature obsolescence, foetal congenital defects and even death caused by BVD infection. In the Netherlands, existing studies on potential losses due to BVD are based on relatively outdated data and hardly evaluate losses in relation to a new bovine viral diarrhoea virus (BVDV) infection in a surveillance system. In China, BVD research mainly focuses on epidemiology, studying the epidemic characteristics of BVD and effects of control measures. Insights on the economic effects of BVD in Chinese dairy farms are less well known. Besides, no official BVD control programme exists.
The objective of this PhD research is to support the decision making in the control of BVD in Chinese dairy farms by providing insights into the impact of BVD and BVD control in the Netherlands.
This PhD research is sponsored by China Scholarship Council (CSC) and Sino-Dutch Dairy Development Centre (SDDDC) and is expected to complement the economics research on BVD control in China and to contribute to the formulation and implementation of China's BVD control plan.
