Heat stress in Swine | Lallemand Animal Nutrition

Lallemand Animal Nutrition offers different solutions to pig producers to help sows, growing and fattening pigs deal with heat stress.

Heat stress in pigs occurs when the environmental temperature exceeds their thermoneutral zone, causing them to activate several mechanisms to dissipate heat. This leads to reduced activity, apathy, rapid breathing, high heart rates, and metabolic issues. With global temperatures rising, heat stress is increasingly problematic for swine production, resulting in significant annual losses.
As a global leader in yeast and bacteria production, Lallemand Animal Nutrition has developed a multi-solution approach based on nutrition to help address the challenges of heat stress for sows, growing and fattening pigs.
