Because chicken skin is tightly covered with feathers, there is no sweat glands, and the summer weather is hot, the resistance of laying hens is reduced, and their egg production is greatly affected. In order to ensure the stable production and high yield of laying hens in summer, the following key measures must be taken seriously in the feeding and management: First, reduce the density After entering the summer, the breeding density of the flock should be reduced in time according to the rising temperature. In the summer, 5 laying hens per square metre are appropriate. After plunging, the breeding density can be reduced to 4 per square metre. Second, open the window when the chicken coop when the temperature rises above 25 °C, it is necessary to open the window in time, install the ventilation screen; when the chicken house temperature is higher than 30 °C, take a shelter in the venue close to the house yin. The arbor is about the same size as the chicken house, but it should be about 50 cm above the house. 3. Change drinking water frequently In summer, in order to prevent the chicken's drinking water from being exposed to the sun's heat, the drinking fountain should be placed in a cool place, and often change the water. It is better to let the laying hens drink the well water that was just hit to reduce the water. Body temperature. Fourth, early morning and late summer, the first day of the summer should be put chickens on the venue to feed the first round of food, etc., and then circle the chicken after dark, try to reduce the time spent laying hens in the henhouse. After getting into the volt, you can also use some wooden shelves under the pergola to let the chicken stay under the pergola overnight. Fifth, scientific feeding in the summer long hours, should increase the number of layers of feeding to stimulate the layer of appetite. At the same time, to reduce the proportion of corn and sorghum in their feed, the amount of corn used should be controlled within 45%, the amount of sorghum used should not exceed 5%, and sorghum should not be fed, and the amount of bran, fishmeal, beancake or peanut cake should be appropriately increased. VI. Doing a Good Job of Preventing Diseases The breeding of mosquitoes and flies in summer is very easy to induce various infectious diseases of chickens. Therefore, we must conscientiously do a good job of disinfection and epidemic prevention of chicken houses. The shed should be cleaned once a day, and the sand should be dug in the ground; after each rain, the stagnant water in the chicken activity site should be promptly cleaned, and the hens should not be allowed to drink filthy water; the troughs should be frequently cleaned and exposed to sunlight; About half a month, the house was sprayed with 2% caustic soda. Garlic mash, mix in the feed, fed once every 3 to 5 days, but also have a certain effect of epidemic prevention.
