In summer, laying hens are prone to illness due to changes in environmental conditions, which have a great influence on egg production. In order to ensure the stable production and high yield of laying hens in summer, the following key measures must be taken seriously in feeding and management. First, reduce the density. Laying chickens are particularly afraid of heat. Therefore, after entering the summer, the chicken breeding density should be reduced in time according to the rising temperature. It is advisable to raise 5 eggs per square meter when the laying hens enter the summer, and it can be reduced to 4 after entering the volatility. Second, open the window scaffolding. When the temperature rises above 25°C, open the windows in time to install the ventilation screens. When the temperature is higher than 30°C, use a pergola on the activity area close to the chicken. The pergola should be the same size as the chicken house, but it should be higher. The chicken house is about 50 cm. Third, change drinking water. Summer drinking water in the chicken bowl is easily exposed to the sun, the water cooler should be placed in a shaded place, and the water should be changed frequently. It is best to allow the laying hens to drink the well water they just hit to reduce the temperature in the hens. Fourth, early evening laps. When the sky is bright in summer, the chicken should be put on the activity floor to feed the first round of food. After dark, chickens should be circled. Minimize the time it takes for laying hens to stay in the hen house. After entering the volley, you can also use some wooden stand under the pergola for the chickens to inhabit, let the chicken stay under the pergola overnight. Fifth, science feeding. Summer sunshine time is long, should increase the number of feeding, it is best to feed once every 3-4 hours. Feed more and more in the morning and evening, feed less at noon, add two feeds per meal, half an hour in order to induce increased appetite in laying hens. In summer, the proportion of corn and sorghum should be reduced in the feed of laying hens, corn should be controlled within 45%, sorghum should not exceed 5%, and sorghum can not be fed, and the proportion of bran, fishmeal, bean cake or peanut cake can be properly increased. Sixth, do a good job of prevention. Tombs grow in summer and spread diseases easily. Therefore, we must conscientiously do a good job of disinfection and epidemic prevention of chicken coops and prevent diseases. The shed should be cleaned once a day, and sand and sand must be added. After each rain, remove the stagnant water on the chicken's activity area. Do not let the hens drink dirty water. The trough should be cleaned regularly and sterilized in the sun. Every second and a half months, a 2% caustic soda spray was used to disinfect the bed bugs. They were found to be diluted with 500 dichlorvos and sprayed into wall joints for killing. Because laying hens are more sensitive to dichlorvos, chickens must be rushed out of the house before spraying. In summer, garlic can also be smashed into the feed and fed once every 3-5 days. It also has a certain effect of epidemic prevention.
