Use of ammonium chloride and sodium bicarbonate in acute heat exposure of broilers

Ammonium chloride (NH4Cl) and sodium bicarbonate (NaHCO3) were added separately to the drinking water of 42- to 52-day-old broilers. Birds were given access to the water ad libitum for a total of 42.5 hr consisting of 18.5 hr prior to an 8-hr interval of severe heat exposure and a further 16 hr-post...

Description
Summary:Ammonium chloride (NH4Cl) and sodium bicarbonate (NaHCO3) were added separately to the drinking water of 42- to 52-day-old broilers. Birds were given access to the water ad libitum for a total of 42.5 hr consisting of 18.5 hr prior to an 8-hr interval of severe heat exposure and a further 16 hr-post exposure. Water and feed intake during the treatment period were unaffected by either NH4Cl at 6.25 g/liter (.63%) of distilled water (DW) or NaHCO3 at 3.15 g/liter (.32%) DW. Water intake was increased by approximately 20% in birds given water containing 6.25 g of NaHCO3/liter (.63%) DW, while both feed and water intake were severely limited by NH4Cl at 31 g/liter (3.1%) DW. Blood pH of birds was substantially lowered by consumption of NH4Cl, while consumption of NaHCO3 did not significantly affect blood pH. Blood pH of all treatments increased during the heat exposure period and declined afterward; however, blood pH change appeared to be more pronounced for birds receiving the NH4CL. A correlation coefficient (r = -.31) existed between blood pH and mortality, while a correlation (r = -.72) was demonstrated between water consumption and mortality.
