Kemin’s Answer To Poultry Heat Stress

Heat stress is a recurring problem that continues to challenge the poultry industry. That’s because the absence of sweat glands in birds makes thermoregulation a  complex problem to solve.

When faced with heat stress, birds direct energy away from growth and production in favor of maintaining thermoregulatory homeostasis. They also lower their feed intake in an attempt to reduce the amount of endogenous heat they produce by digestion. The combination of these factors results in costly losses in bird performance.

That’s why at Kemin we have a multifaceted strategy to solve your poultry heat stress problems. We recommend using a nutrient absorption enhancer, energy efficiency booster, and immunomodulating beta-glucan to counteract the negative effects of heat stress on immunity, performance, and meat quality.

Kemin’s Answer To Poultry Heat Stress

Heat stress in poultry impacts negatively on a wide range of production aspects. Heat stressed birds grow more slowly, produce fewer eggs, and have a higher rate of disease - all of which reduce farm productivity. Heat stress has been implicated in reduced bird fertility, immune suppression, recurrent digestive disorders, and high oxidative stress states. At Kemin, we know that effectively managing the impact of heat stress is crucial to running a successful poultry business.

Poultry do not have sweat glands, making thermoregulation when exposed to heat stress quite complex. This problem has been further exacerbated by improvements in poultry genetics. Birds now grow faster and have higher metabolic rates. As a result, the birds produce more body heat making them increasingly prone to heat stress. Increased ambient temperatures as one of the most immediate and obvious effects of global warming, along with higher stocking densities, also contribute strongly to the frequent occurrence of heat stress. 

  • Birds  drop their wings to increase their heat loss surface area and they start to pant.
  • Panting birds drink significantly more as they lose a high amount of water through their respiratory tract.
  • The high respiratory rate seen with panting can also lead to respiratory alkalosis, a cause of acid-base imbalance.
  • Energy is directed away from growth and production in favor of maintaining thermoregulatory homeostasis.
  • Less feed is consumed in an attempt to reduce the amount of endogenous heat produced by digestion.
  • Blood is redistributed away from muscle tissue to the skin and respiratory tract.

Managing heat stress is not an easy task. Nutritional and immunomodulating interventions are effective in reducing the severity of heat stress and reducing the associated detrimental effects. However, such interventions need to be properly managed. Our experts are here to support you every step of the way.

A multifaceted approach to reducing the effects of heat stress is vital to maintaining your animal’s welfare and profitable production. We support you in this quest by recommending three key products: 1)  a nutrient absorption enhancer, 2) an energy efficiency booster, and 3) an immunomodulating beta-glucan to counteract the negative effects of heat stress on immunity, performance, and meat quality.

In addition to the simple fixes of reducing stocking density and adjusting lighting regimes, the application of a nutrient absorption enhancer such as LYSOFORTE® EXTEND, in conjunction with diet reformulation and the use of an immunomodulating β-(1,3)-glucan such as Aleta™, can assist to limit the negative effects of heat stress on immunity, performance, and meat quality.

Our research has shown that using KEMTRACE™ CHROMIUM, an organic, highly available source of chromium, is able to suppress the production of “stress markers” like cortisol and catecholamines generated in response to heat stress. KEMTRACE CHROMIUM is also able to improve your birds' insulin efficiency and facilitate heat loss by optimizing blood microcirculation, thereby improving lean muscle growth.
