TL;DR: The culling of cows with chronic infection was associated with an increase in the economic impact of mastitis and a reduction in the average productivity per cow, and at the herd level reduction in milk production was the component that presented the largest weight in theeconomic impact of the disease.
Journal ArticleDOI
