Chickens have no sweat glands, full plumage, and difficulty in heat dissipation. Chickens are most prone to heat stress in summer and autumn. Adding drugs to relieve heat stress in the feed has a good control effect. 1. Add vitamin C. Vitamin C can reduce chicken body temperature, increase feed intake, and reduce heat stress. Adding 500 mg of vitamin C per kilogram of feed not only relieves heat stress, but also increases egg production by 12%. 2. Supplement vitamin E. In the summer and autumn chicken feed, vitamin E can reduce the heat-stress mortality of chickens by 55% to 74%. 3. Add Rod Peptide. Adding 100-150 ml of Peptide Peptides per kilogram of feed and supplying enough clean drinking water can better reduce heat stress and increase egg production. 4. Add aspirin. Aspirin helps the body's heat balance. Adding 0.05% of aspirin to the chicken's diet can effectively increase chicken heat dissipation and increase egg production. 5. Add sodium bicarbonate. In the hot season, adding 0.1% to 1% sodium bicarbonate to the chicken diet can better relieve heat stress, increase eggshell thickness, and increase egg production by 8%.
