Chickens are warm-blooded animals with rich feathers, no sweat glands on the skin, and good thermal performance and poor heat dissipation. Especially in the hot summer season, if the feeding and management are improper, it can easily cause the increase of body temperature, thus affecting the normal development of its growth and production performance. Therefore, it is very important to manage the laying hens in summer. First, to strengthen environmental management 1, outside the environment to manage the tree planting flowers: 2-3 meters away from the house, should be planting fast-growing trees, the tree must be trimmed during the growth process, so that the canopy is about 1 meter higher than the eaves to Avoid direct sunlight. Rattan climbing plants such as creeper and morning glory can also be planted to shade, absorb sunlight, increase oxygen production, and improve the microclimate. White roof: The top of the house should use non-heat absorbing white material or paint to reduce heat radiation. There are many materials available, such as galvanized sheet. It has been proved that the use of a white roof can reduce the indoor temperature by 2-3 °C. 2. Home environment management Strengthen ventilation: Good ventilation is an important measure to ensure the environment inside the house. In the summer, pay attention to open doors and windows, activate ventilating devices such as exhaust fans and ceiling fans, remove obstacles and obstructions to air flow, and maximize the flow of air in the houses to reduce the temperature. It is better to use vertical ventilation. Vertical airflow distribution in the house is evenly distributed, and there is basically no airflow dead angle. This overcomes the disadvantages of lateral ventilation in the sheltered side of the house, which is relatively weak in the summer, and strong in the windward side in the winter. Fresh air can be fully utilized and the airflow speed is high, generally above 0.5m/s, which is beneficial to the heat dissipation of the chicken body. Spray water cooling: spray water cooling is a common way to reduce temperature in chicken farms. A rotary atomizer or sprayer can be installed in the house to spray the chickens intermittently with small droplets to remove the heat emitted by the body, but not to cause too much humidity. Cold water can also be sprayed on the roof to increase evaporation and heat dissipation, which has a good cooling effect. Reducing density: Excessive density is not conducive to the distribution of calories in the chicken body, which can easily lead to the occurrence of heat failure syndrome. Therefore, the feeding density should be appropriately reduced according to the different age of the chicken. Cleaning the excrement: The excrement in the house should be cleared in time to prevent the accumulation of excrement and the environment. Second, to strengthen nutrition management 1, adjust the diet caused by hot environment caused by changes in physiology and metabolism, resulting in reduced feed intake, decreased production performance. Appropriate adjustment of diet can compensate for the reduction of nutrient intake caused by high temperature stress, meet the special needs of laying hens, and relieve the damage of heat stress to some extent. Increase fat to reduce carbohydrate content: Because of the high energy content of fat, less body heat is produced by metabolism. Adding 3% fat can satisfy the energy requirement of laying hen without increasing food intake, and increase the palatability of feed and Utilization rate. Carbohydrates produce more heat in the process of digestion and metabolism, which tends to aggravate the heat-dissipation burden. Therefore, the proportion should be appropriately reduced. Increase protein and amino acid content: Increasing protein intake is more beneficial than increasing energy in heat stress conditions. Increasing methionine and total sulfur amino acid intake can significantly increase egg production. Increase multi-vitamin content: chickens are particularly vulnerable to vitamin deficiency due to heat stress. Therefore, it is necessary to increase the vitamin content of the diet. In general, the amount of multivitamins can be increased by 2-3 times during the hot summer months. . In particular, vitamin C is one of the most studied anti-heat stress additives at home and abroad. Adding 200 mg/kg vitamin C to diet or drinking water can significantly reduce the effect of heat stress on laying hens, thereby reducing the mortality of the chicken population. Vitamin A is also easily deficient at high temperatures. Properly increasing vitamin A levels can promote antibody synthesis and T cell proliferation, and can increase feed intake and egg production in laying hens. 2, to improve the feeding method Summer should choose a cool climate sooner or later add more feed, no less at noon to add the method to ensure the intake of the diet, but also can be used to improve the chicken's excitability and strong exuberant appetite. 3, to ensure adequate drinking water Summer must ensure that all day free drinking water, but also to ensure fresh and cool, if the water shortage in the hot summer time is too long, affecting the chicken's growth and production performance. In order to ensure that each chicken drink enough fresh cold water, should be placed enough drinking equipment, but also to a high degree of appropriate, uniform layout, water temperature is appropriate to about 10 °C, and should pay attention to ensure the cleanliness of drinking water appliances, the best brushing and disinfection every day Once, prevent water pollution at high temperatures. The drinking water quality of chickens must meet the standards set by the state. The sensory traits must not have any unusual odors or odors, and should not contain visible substances. The pH should be 6.4 to 8.0, and the bacteriological index should be 1/100ML. While ensuring sufficient drinking water, the floor of the house should be kept clean to prevent excessive humidity caused by watering and water leakage. 3, adjust the electrolyte balance Heat stress prone to respiratory alkalosis and hypokalemia, resulting in electrolyte imbalance, affecting the body's regulatory activities. The sodium bicarbonate, ammonia chloride, and potassium chloride can significantly regulate the balance of electricity. The practice shows that 1% ammonium chloride and 0.5% sodium bicarbonate are added to chicken feed and 0.2% potassium chloride and chlorinated water are added to drinking water. Ammonia can reduce the harm caused by heat stress. Third, to strengthen daily management 1. Regular observation of chickens, to grasp the health of the flock and appetite and other conditions, pick out the diseased chickens, stop production of chickens, pull out dead chickens. 2. Regularly observe the quality of eggs such as eggshell, egg white, egg yolk concentration, egg yellow pigment, blood spots, meat spot eggs, sauerkraut eggs, misshapen eggs, especially large eggs, and high rate of broken eggs. Analyze the causes promptly and take appropriate measures. . 3. Light bulbs should be wiped once a week. Bad bulbs should be replaced in time to ensure proper illumination. 4. The staff should be light in the house and do not have special sounds. Try to avoid causing disturbances to the flock. 5. Complete all operations on time and on time. The time of day's on/off light, feeding and feeding of water, quail eggs, and excrement shall be performed and completed in time according to the specified working time.
