As global temperatures rise and heatwaves become more frequent, fattening livestock are increasingly exposed to heat stress. This condition can lead to reduced feed intake, poor weight gain, suppressed immune function, and even mortality. In such conditions, targeted nutritional strategies can play a key role in minimizing the harmful effects of heat and maintaining animal health and productivity

Heat stress is one of the biggest challenges for dairy cow health and productivity, especially during hot and humid seasons. When environmental temperature and humidity exceed the animal’s capacity to dissipate heat, the cow experiences physiological stress. This leads to increased respiration rate, heart rate, and hormonal changes, ultimately reducing feed intake and digestive efficiency

Live yeast, usually a strain of Saccharomyces cerevisiae, is a type of feed additive that is commonly added to dairy cow diets to improve digestive performance, particularly in the rumen. These yeasts help enhance the environment in the rumen by removing oxygen, which in turn promotes the growth of beneficial anaerobic bacteria. As a result, cows are able to digest their feed more efficiently, especially fibrous components, leading to better nutrient absorption and energy availability
