Jason Warner and Justin Waggoner share environmental variables that change thermoneutrality for cows as they weather cold. Nutrition requirements also need adjustments as it takes increased energy to produce extra body heat.
Warner and Waggoner provide data and offer points for producers to consider when managing cow herds through cold stress. The article is actionable as it reinforces the need for daily monitoring. Consider sharing the article with producers on social media, in a Zoom meeting before calving ramps up or in newsletters.
