Rev up your cow’s rumen to prevent SARA during heat stress

Have you ever felt like it’s too hot to eat? During periods of heat stress, cows can feel the same way. Just like humans, cows often change their feeding behavior as temperatures and humidity rise. But, while most people can skip a lunch or two without serious consequences, high-producing dairy cows shouldn’t miss a meal if you want to keep peak performance.

“When the temperature-humidity index rises, dairy cow meal frequency generally goes down, and meal size often increases,” explains veterinarian Andy Skidmore, Lallemand Animal Nutrition Technical Services – Ruminant.

“These behavioral changes can affect rumen pH and function, leaving cows vulnerable to sub acute ruminal acidosis (SARA), which cuts into ration and milk component performance,” he adds.

Adding a live yeast probiotic like S. cerevisiae CNCM I-1077 to dairy rations can help slash SARA’s influence on your herd. Here’s what you need to know:
