Winterizing Calves

12/29/2021

The cooler days and nights are here, and a good reminder of taking steps to winterize the things in our lives: vehicles, homes, and wardrobes. Winterizing is a proactive solution that helps us avoid problems associated with dropping temperatures and is a tactic that can also be applied to your calves.

When the temperature is low, a calf’s body responds by producing heat (thermogenesis), which for a newborn calf is often produced one of two ways—The breakdown of brown fat (BF), which is readily available energy.  Or by shivering, which produces heat in a similar way to exercising or moving around. The latter can and should be avoided as it takes energy from the calf that could be used for growth and health.

In this article, we’ll discuss how cold weather impacts calf nutrient requirements and how we can change our milk replacer feeding program in winter to maintain calf performance.

As the temperature drops we all change our habits to regulate body temperature.

But small calves cannot thermoregulate well, and we need to adjust management to help them remain productive during the winter.
