1. Adding vitamin C. Vitamin C can reduce the body temperature of the chicken, increase feed intake, reduce the heat stress response. Vitamin C500 mg per kilogram of feed, both to ease the heat stress and raise laying rate 12%.
2. Supplement of vitamin E. In the summer and chicken feed, vitamin E can the chicken heat stress mortality decreased from 55% to 74%.
3. Rod peptide to bacteria. 100 to 150 ml per 1 kg of feed rod peptides bacteria, and supply enough clean drinking water, better able to reduce the heat stress, but also improve the laying rate.
