Abstract
Epidemiological evidence is presented in order to answer two questions. The first question is: “Does high milk production put a cow at increased risk of disease?” The answer to this question seems to be “maybe” for milk fever, but “no” for most other common diseases (veterinary-assisted dystocia, retained placenta, metritis, cystic ovary, ketosis, left displaced abomasum, and mastitis). The second question is: “Is low milk production a consequence of disease?” For most diseases the answer is a cautious “yes”.
