Effects of Methionine‐Supplemented Low‐Protein Diets on Production Efficiency, Heat Resilience, and Welfare of Broilers in Tropical Climates

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Methionine supplementation increased feed intake, reduced abdominal fat and total cholesterol levels, and improved physiological parameters in broilers. Thus, methionine supplementation to a low‐protein feed improves production efficiency, heat resilience, and meat quality in broilers reared in hot, humid conditions.
