By Cassy Golburg, B.A.

Most livestock producers are familiar with the negative effects of heat stress in lactating cows, but the impact heat stress has on calves and heifers is often overlooked. Heat stress can not only cause a negative impact on calf health but can also cause a negative impact on producer profitability. There are a variety of health issues calves experience from heat stress including dehydration, lower average daily gains, and higher morbidity and mortality rates. A study from Penn State Extension showed that calves exposed to heat stress early in life often had long term ramifications, such as smaller breeding size and an older age at first lactation. These factors ultimately play a large role in decreasing producer profit. Crystal Creek® can help producers evaluate the impact heat stress is having on their calves and determine what steps can be taken to prevent long-term repercussions from it.

The skin is the frontline defense mechanism for every animal and as a result, it is under constant challenges from toxins, infectious agents and physical stresses. It’s more than just a physical barrier between the body and the environment; the skin is an active immune organ. Specialized immune cells found only in the skin are always on the lookout, patrolling for infection.

When discussing calf barn ventilation, invariably the topic of using four air exchanges per hour for cold weather ventilation will come up. After all, we wouldn’t want “too much” of that cold air in the barn. Or would we? Who came up with the idea to use four air exchanges per hour during cold weather and why? To understand our industry’s current ventilation recommendations, we must first understand the history of calf barn ventilation research.
