Also pay attention to supplement the fat-soluble vitamins, especially vitamin E. Adding 50 mg of vitamin E per kilogram of feed can promote sperm formation and enhance sperm viability.
Fifth, reduce stress: keep the environment relatively quiet. During the high-temperature period, vitamin C150-200 mg is added per kilogram of feed to enhance the body's ability to resist heat stress.
