The transition period is a very challenging period for the dairy cow. Her metabolism needs to adapt rapidly from a non-lactating to a lactating stage, and the reproductive system is preparing new ova for the next breeding period.

Over the last 50 years, milk production of dairy cows has essentially doubled in Canada. Even if cows consume an increased amount of dry matter, meeting the early lactation nutrient needs of high-producing dairy cows is a big challenge. The transition period is, more than ever, a critical period.

During the transition period, dairy cows encounter high metabolic and nutritional demand and a reduced immunity, predisposing them to metabolic and health problems. This will reduce their productive life and impact negatively the profitability of the dairy farm.
