Heat Stress

Heat stress has increasingly become more severe over the last decade and it affects the animal farming industry globally with huge economic losses. Heat waves increase the chances of livestock experiencing heat stress, especially when night-time temperatures remain high, and animals are unable to cool off. Extreme temperatures - hot and cold - across the globe are getting more frequent and intense. Unfortunately, the damaging consequences of heat stress in animal production and health are expected to continue and intensify in the future, especially if thermotolerance and climate adaptation practices are not addressed. Thus, farm animals are seriously affected by extreme temperatures and need further support against the consequences of heat stress.

Heat stress can occur irrespective of animal species, immune status, and age. The fast metabolic rate, rapid growth, and high level of production make swine, poultry, and ruminants particularly susceptible to heat stress. Swine and poultry suffer from heat stress due to the absence of functional sweat glands and inability to release heat through sweat as well as due to the presence of skin insulation provided by the subcutaneous fat in swine and by feathers in poultry. In ruminants, the heat released during the process of feed fermentation in the rumen increases the metabolic heat production and affects their thermoregulatory mechanisms.

Innovad® Heat Stress guide

To help our customers combat the detrimental effects of heat stress on animal health and performance, we have created an Innovad® heat stress guide. The guide provides a detailed overview of the consequences of heat stress in livestock and discusses ways in which we can support animals, maintain productivity, and prevent economic loss.
