First, increase the protein feed properly In the summer and autumn, the temperature is high. Due to the heat stress, the feed intake of chickens will decrease significantly. If nutrients are not added to the diet, they will not be able to meet the need for growth and production of laying hens due to reduced feed intake. Due to the lack of protein in the summer diet of laying hens, it will directly affect the egg production. Therefore, the protein content in the summer diet should be 1~2% higher than that in other seasons. That is, it is necessary to increase the feed of soybean cake or cottonseed cake in the diet, and the amount can reach 20~25%. In addition, the amount of animal protein feed such as fish meal, meat blood meal or fish and shrimp waste can account for 5 to 7% of the feed. Second, appropriate increase in mineral feed Most of the laying hens in summer and autumn are in the middle and late stage of peak egg production. The demand for calcium in the flock is increased. Therefore, the calcium and phosphorus ratio in the diet should be appropriate, and the calcium content in the general compound feed should be adjusted to 3.8%. The excessive or too little calcium content in the compound feed will affect the palatability of the material and the egg production rate of the chicken. In order to increase the intake of calcium without affecting the palatability of the feed, the shell powder can be separated from the feed and fed in a single tank, allowing the chicken to feed freely to meet the needs. Third, increase the green feed and heat stress additives Adding some green and blue succulent feeds to layer chicken feed in summer and autumn can reduce the amount of multivitamins in the feed, even without feeding multivitamins (obtained from the green feed). Feeding green and blue succulent feeds can also increase feeds. The palatability, saving part of the diet and reducing the cost of raising chickens. At the same time, some anti-heat stress drugs such as vitamin C and baking soda can also be added to the feed. To reduce the impact of high temperature on layer chickens. The amount of green feed should be appropriate and generally not exceed 30-40% of the diet. Fourth, appropriately reduce the energy feed Because the summer and autumn temperatures are high, the energy needed for chickens to maintain their own body temperature is much lower than in the cold season. Therefore, in the summer and autumn (diet) layer diets, corn, sorghum, and other high-energy concentrates should be appropriately reduced, and the amount used is generally not to exceed. 50~55%. At the same time, some bran-based roughage feeds with low energy content can be added, and the amount used should not exceed 15-20%.
