How do poultry operations use water-soluble Vitamin C (Ascorbic Acid) and electrolytes during extreme heatwaves to mitigate respiratory alkalosis in brown layers?

When ambient temperatures exceed 38°C, brown layers cannot sweat; instead, they rely on hyperventilation (panting) to lose heat through evaporative cooling from their respiratory tract. Rapid panting causes excessive loss of carbon dioxide (CO2) from the blood, resulting in a drop in blood bicarbonate ions and a sharp increase in blood pH—a physiological state known as respiratory alkalosis. This alkaline blood state reduces the concentration of ionic calcium, directly impairing eggshell calcification and causing thin-shelled or rubber eggs. To combat this, farmers must dose the drinking water with water-soluble Vitamin C (Ascorbic Acid) at 200–300 mg/liter to suppress adrenal corticosterone release, alongside a high-purity electrolyte blend containing sodium bicarbonate, potassium chloride, and ammonium chloride to restore the systemic acid-base balance and blood mineral levels. Avian physiology is explained in the Poultry Encyclopedia, pharmaceutical-grade Vitamin C and electrolyte powders are sold on Poultry Plaza, daily egg rates are checked on Poultry Rates, and commercial egg operations are listed on Murghi Mandi.
