Growing birds in hot conditions is a major challenge of ours for today and tomorrow. Heat stress is a multifactorial challenge but exhibits oxidative components. At a cellular level, heat induces an over production of free radicals, from which the cell needs to be protected. In case of chronic heat stress, the body mobilizes a lot of energy to activate its antioxidant mechanisms and achieve thermo-regulatory adaptations. Contemporary, heat stress impacts the behaviors of animals which will eat less, and thus have a slower growth. In that case, the genetic potential of broilers is often not reached. Consequently, profitability is reduced.
Selisseo® is a pure organic selenium based antioxidant, with high potential for counteracting the negative effects of oxidative stress.
In a recent study led by INRA-URA, France, Selisseo® was compared to sodium selenite. Broilers were subjected to a thermoneutral environment or a heat stress environment. Heat stress induced a drop of performance for both selenium treatments. Nevertheless, for Selisseo® fed broilers, this drop was alleviated, as they performed better compared to the sodium selenite group: + 50 g / broiler and – 1 pt FCR. By extrapolating this extra weight gain to a production of 1 million broilers, this is equivalent to an additional profit of 45,000 €.
Using Selisseo® in broiler feed helps reducing the impacts of heat stress, since broilers can better withstand oxidative stresses and thus perform better. This directly translates into higher profit for producers.
