Organic chromium against heat stress in broilers
Broilers kept at 35 °C from day 15 to 42 ate less, grew less and had weaker immune responses. Adding chromium-methionine (500–1000 µg/kg) increased feed intake, weight gain and feed efficiency, and the benefit was larger in heat-stressed birds. 500 µg/kg also restored part of the immune response.
Practical takeawayIn hot seasons, chromium-methionine helps broilers keep growing and protects their immunity.
