(1) Diagnostic criteria was forced into the multivariable analysis (2) When claw disease increased by 10%, the mastitis incidence rate was increased by 3.67 cases/100-cow years. (3) When milk production increased by 10 kg, the mastitis incidence rate was increased by 12.56 cases/100-cow years. | ||||
