Heat stress is a common and growing concern in dairy production, and we are now fully aware that it is not limited to two summer months or tropical regions and could be an issue for long periods. By monitoring the temperature and humidity level within the animals’ environment (in the barn) — but also assessing visible indicators such as rumination, locomotion, or undigested grains in manure — producers can better anticipate heat stress issues and make the necessary adjustments before dairy production starts falling.
Although there is less visibility, fattening cattle suffer just as much as dairy cows in warm temperatures. From 25°C onwards, the animal immediately decreases its feed intake, which then takes several days to stabilize again, even at lower temperatures. Rumen conditions and efficiency are challenged by heat stress in beef too, resulting in impaired growth performance and health. Risk monitoring, planning ahead, and adapted barn and herd management practices are essential to optimize production and help overcome heat stress challenges in beef.
Live yeast, used as a rumen modifier, has proven its efficacy to help alleviate the negative effects of heat stress on feed efficiency, thanks to its positive effect on rumen pH and feeding behavior under such challenging conditions in both dairy and beef cattle.
