When it comes to developing ketosis — both subclinical and clinical cases — high milk production (increasing parity) and excessive body condition only account for about 10 percent of a cow’s risk. The other 90 percent comes from management factors, explains Todd Duffield, dairy scientist at the University of Guelph.

How you manage transition cows, including nutrition, bunk management, grouping, movement of cows, cow comfort, ventilation and cooling, all affect her risk for developing ketosis. With good management, even high-producing cows can avoid ketosis.
