As the dairy industry continues to face economic pressure and limited replacement animals, the importance of transition cow management is becoming clearer. By focusing more attention on the dry period through nutrition, management and stress reduction, producers can help cows become stronger and more resilient.

There is a stretch of time on every dairy that quietly determines how well a cow will perform during her lactation. The transition period is when cows either get off to a smooth, productive start or begin a chain reaction of health and performance problems that are hard to fix later.

Transition cows are prone to inflammation, hypocalcemia and metabolic disorders that can lead to lower chances of getting pregnant and long-term consequences on the health and productivity of the cow – all of which can take away from a dairy producer’s bottom line.

One factor that plays a role in the success of the transition period is the cow’s body composition, more specifically the fat and muscle of the cow. Both fat and muscle tissues are mobilized during the transition period to compensate for the negative nutrient balances and provide precursors for milk and milk components.

The dry period, usually lasting 60 days before calving, serves essential roles in preparing cows for lactation, promoting mammary cell renewal and facilitating treatment for subclinical mastitis. However, shortening or eliminating this period has become a strategy to manage milk production, redistributing energy balance and mitigating the risk of metabolic disorders like subclinical ketosis.
