About 140 farms, where dairy cows had clinical signs of ketosis or acetonuria, were studied to find out whether farm management had any influence on the occurrence of these phenomena and whether outbreaks could be prevented by practical measures in this field.

The results did not indicate that there was any connection between general factors of management (such as kind of soil, and rate of stocking) and the induction of ketosis. They did not support the suggestion that outbreaks were usually associated with only a few types of ration or a small number of fodder combinations. But there were indications for a relation between feeding value of the ration and development of acetonuria and ketosis.

Consequently this relation was further studied. Considerable influence could be exercised against development of acetonuria and ketosis in cows, particularly with the ration given during the first days and weeks after calving. The ration during the dry period, in particular during the last two weeks, seemed to be of importance only in that feeding value and composition of the daily ration during that period must allow rapid adjusment of the ration to the cow's milk yield after calving.
