1. Feed vitamin C. Adding vitamins to laying hens' diets can reduce the body temperature of laying hens, increase the feed intake of laying hens, and increase the egg production rate. Generally, 500 mg vitamin C is added per kilogram of feed, and the egg production rate can be increased by 12%. 2. Feed vitamin E, B6, B12. Adding vitamin E, B6, and B12 in a suitable amount in the layer chicken feed can improve the body's thermoregulation function and play an important role in preventing the rise of several body temperatures. 3. Increase the amount of multivitamins. Feeding laying hens under hot weather conditions can increase the amount of multivitamins by 1 time. 4. Feed the watermelon rind. Under high temperature conditions. Each chicken in the layer chicken diet was fed 50-100 grams of chopped rind rind. After one month, the egg production rate increased by 5%, and the average egg weight increased by 0.2 grams. 5. Feeding baking soda, under high temperature conditions, adding 0.3%-0.4% baking soda to the layer diet will help to increase the activity of phosphorus in feed and meet the requirement of phosphorus for layer chickens. In addition, the thickness of the shell increases by 8%, and the average egg production increases by 10%-15%. Baking soda can also be added in drinking water. 6. Feed celery. Feeding chickens with celery can not only supplement the vitamins needed for laying hens, but also increase the egg production rate by the shell, and at the same time it has a good control effect on the damage and anorexia of laying hens. The specific feeding method is: feeding celery 4 times a week, feeding 50 grams per layer of eggs, feeding the celery leaves, cutting the celery stems and mixing them in the feed. Use 2 kg of celery root every day, and cook for 3 to 10 minutes in clean water of 3 kg to make the chicken drink water. The effect is also good. 7. Feed zeolite powder. Adding 3 powders of zeolite to layer diets can increase production by 10% and save feed. 8. Feed aspirin. Aspirin is an antipyretic drug that promotes heat dissipation and helps maintain heat balance. Adding 0.05%-0.15% aspirin to layer diets can increase egg production by 5% and increase egg weight and shell thickness. 9. Bacitracin-bound zinc. Bacitracin zinc is a heat stress reliever with good effect. In the diet of laying hens, 100 mg of Bacitracin zinc is added to every kg of feed to produce laying hens. Even if the ambient temperature reaches 34°C, the hens can maintain. Higher feed intake and favorable egg production generally increased egg production by 5.4% and feed utilization increased by 5.8%. 10. Feed chlorpromazine. A certain amount of chlorpromazine is added to the layer chicken feed to increase the heat resistance of the chicken and increase the egg production and egg thickness. 11. Feed the blood level. Add 1.6 ml of reserpine to each kilogram of chicken feed. The shell enhances the chicken's resistance to heat, increases egg production and improves egg quality. 12. Increase feed concentration. High temperatures cause the appetite of chickens to decline, and feed intake decreases. If the proportion of diets such as protein, vitamins, and minerals is not increased, the intake of protein, vitamins, minerals, and other nutrients in chickens will be seriously insufficient. Causes reduced egg production. Therefore, dietary nutrient concentrations should be increased according to feed intake to meet the nutritional needs of chickens and increase egg production. 13. Choose the right feeding time. The high temperature during the summer noon and the low appetite of the chicken, so you should choose to feed the chicken in the morning and in the evening. This shell enhances the feed intake of the chicken, satisfies the nutritional needs of the chicken body, enhances the chicken's ability to regulate body temperature, and increases the egg production rate.
