Dairy cattle face numerous sources of stress, expected and unexpected, throughout their life cycle. One of the most predictable is heat stress, which can compromise cow health and production, both of which can have a significant economic impact on the profitability of a dairy. The effects of heat stress are estimated to cost the dairy industry up to $1.5 billion annually. Primary economic losses may include lower milk yields, reduced reproductive efficiency and even death.

The aim of a properly managed and nutritionally sound dry cow and early lactation program is to prepare the cow for a profitable lactation. Maximizing dry matter intakes, minimizing negative energy and protein balance, maintaining calcium homeostasis and minimizing immune dysfunction are critical points to a smooth transition into lactation.
