Composition and Method for Treating Heat Stress

Abstract

A method of reducing respiratory alkalosis (high blood pH) and enhanced productivity (rate of weight gain) in poultry during periods of chronic or acute heat stress (high heat and humidity) involving the steps of supplementing the birds' diet (feedstuffs and/or water) with acids (hydrogen ion donor) and bicarbonate donors (NaHCO.sub.3). The addition of an acid donor as a poultry fee or water additive significantly reduces the alkalosis induced mortality rate and enhances the rate of weight gain (up to 30 percent). By including NaHCO.sub.3 in the ration, the rate of gain is further enhanced (an additional 9 percent). The further intentional addition of a sodium free, chloride ion donor also promotes increased rate of gain. The use of a H.sub.2 antagonist (cimetidine) to reduce stomach acid production is also beneficial.
