Genetic parameters for traits derived from measures of electrical conductivity collected by automatic milking systems and their correlations with clinical mastitis in Holstein cattle.

Abstract excerpt

Genetic selection for mastitis resistance in dairy cattle has been conducted through both direct selection on clinical mastitis and indirect selection via correlated traits such as SCS. Even with these efforts, mastitis remains a major concern for the dairy industry. Automatic milking systems collect measures of milk electrical conductivity (COND) for individual quarters of the udder at every milking visit, and...
