Heat stress challenges poultry performance by disrupting hydration, reducing feed intake, and affecting electrolyte stability. Betaine HCl has become a practical inclusion in feed formulations because it supports birds’ natural water balance and helps maintain cellular function during hot periods.

As a methyl donor and osmolyte, betaine HCl assists cells in retaining moisture, reducing the dehydration pressure that typically occurs when birds pant to regulate body temperature. This contributes to steadier electrolyte status, which is essential for muscle activity, nutrient transport, and overall metabolic stability.

Producers using betaine HCl during hotter months often observe more consistent feed conversion and fewer stress-related fluctuations. While it cannot control environmental temperatures, it provides physiological support that helps birds cope more efficiently with heat, making it a useful strategy in modern poultry nutrition.
