Did you know that hot, humid weather has large implications for animal production? Bird's response to rising temperatures can lead to significant performance losses due to lower feed intake which in turn leads to reduced body weight gain and egg production. The consequently decreased feed efficiency is often going along with a strong negative impact on profit.
Heat stress is an important environmental challenge for the livestock industry. In US, the costs of heat stress amount to more than 100 million US$ per year1, whereas the impact on less integrated poultry production in (sub)tropical areas is much higher.
Heat as performance brake
The condition of heat stress occurs when animals are not able to reduce their core body temperature due to high ambient temperature in combination with high humidity. The effect of heat stress can result in unfavorable consequences that range from discomfort to increased mortality. Heat stressed animals change their behavior and physiology to attempt to regulate body temperature, reduce heat production and dissipate heat. Commercial broilers are particularly susceptible to hot and humid weather conditions, as their metabolic heat production is relatively high.
In poultry, reduced feed intake is one of the first noticeable consequences of heat stress. Increased water consumption is another response to heat stress. Housing poultry at high ambient temperatures, especially in combination with high humidity not only impairs production performance but could impair intestinal integrity, natural defense mechanisms and meat quality.
Did you know?
Heat stress in poultry leads to reduced feed intake. Therefore, the energy, protein and additional nutrients necessary for production are lacking and will have negative impacts on performance.
Improve the bird’s resilience
High ambient temperatures and humidity can lead to oxidative stress in poultry due to an increase of free radical production. Without support for the bird’s natural anti-oxidative defense mechanisms, the balance between the production of free radicals and antioxidants can be quickly disturbed. Plant-derived antioxidants can help to maintain this balance and support the maintenance of a normal antioxidative capacity of the bird.
The goal is to provide the poultry with the necessary energy and supporting the use of nutrients, which it needs to maintain a normally functioning natural defense system and stable intestinal function.
