Summer feed for laying hens to increase by one

In hot summer days, laying hens are susceptible to problems such as decreased appetite and decreased feed intake, and therefore their egg production is affected. In order to maintain the high yield of laying hens in summer, experts suggest that they should adjust their dietary levels and make “three increases and one minus.” ——— The editors appropriately increased protein feeds in summer with high temperatures, and due to the effect of heat stress, the feed intake of chickens will drop 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. Because of the lack of protein in the summer diet of laying hens, it will directly affect the egg production, so the protein content in the summer diet should be 1% to 2% higher than 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% to 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. Appropriate increase in mineral feed Most laying hens in summer 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. It is 3.8%. Excessive or too little calcium content in compound feeds will have an effect on the palatability of the ingredients and the egg production rate of the chickens. 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.
Appropriate increase of green fodder and heat stress additives Adding some green and blue succulent feeds to the layer chicken diet in summer can reduce the amount of multivitamins in the feed, even without feeding multiple vitamins (obtained from the green feed). Feeding green and blue succulent feeds can also increase feed palatability, save some rations, and reduce the cost of raising chickens. At the same time, some anti-heat stress drugs such as VC and baking soda can be added to feed to reduce the effect of high temperature on laying hens. The amount of green feed should be appropriate, generally not exceeding 30% to 40% of the diet.
Because of the high temperature in summer, the energy required for chickens to maintain their own body temperature is much lower than that in the cold season. Therefore, summer hens should reduce the amount of high-energy concentrates such as corn and sorghum. Not more than 50%~55%. At the same time, some bran-type roughage feeds with low energy content can be added, and the amount used is generally not more than 15%-20%.
