Continuous high temperature weather not only causes a large number of pathogenic microorganisms in livestock and poultry farms, but also easily causes heat stress in livestock and poultry, resulting in reduced resistance, reduced production performance, and occurrence of heat stroke and other diseases. Therefore, livestock and poultry farms engage in It is particularly important to have a good summer cooling. Different livestock and poultry breeding farms should adopt the following measures for prevention and cooling of heat according to specific conditions and their own characteristics:
1. Improve the facilities of the house by covering the area above or around the house with shading nets and other heat-insulating materials. Widen the eaves and take the pergola to reduce radiant heat and heat of reflection so as to achieve the purpose of cooling.
2. Adding ventilation, water spray, spray cooling equipment and emergency power generation equipment can be cooled conditionally using a wet curtain cooling system. Unconditional fans can be installed in the housing, spraying water and spraying at the top of the house and in the housing from time to time. Can play a cooling role. Water can also be sprayed directly on the head and pig body to reduce body temperature, but a training adaptation process is required in advance. When spraying water or spraying, make sure to ventilate and prevent hot stuffing. Large-scale farms also need to be equipped with power generation equipment to prevent accidental blackouts and affect the implementation of cooling work.
3. Reducing stocking density By reducing the stocking density of livestock and poultry to reduce self-heating, the temperature inside the home is reduced.
4. Properly adjust the diet formula and change the feeding time. Add some substances that help digestion and good palatability (such as active enzyme, multivitamin B, 1% to 3% fat) in the feed (preferably full price compound feed). Etc.) Enhance the appetite of livestock and poultry; use the relatively cool time of morning and evening to feed, feed less frequently, maintain a certain feed intake, and enhance body resistance.
5. Ensure that the drinking water takes shade and heat insulation measures on the water tank to ensure that the livestock and poultry can drink clean and cool drinking water at any time, which is conducive to reducing body temperature. Ten drops of water, Huoxiang Zhengqi Liquid and other drugs can also be added to drinking water to improve the effect of cooling.
6. Reducing various stimuli In hot days, human factors such as crowding, driving, and transport should be avoided as much as possible to prevent heat stress.
7. Add heat stress additives in feed or drinking water, add vitamins (vitamin C, vitamin E, vitamin B2), trace elements (chromium, selenium, zinc), electrolytes (sodium bicarbonate, ammonium chloride), organic acids (citric acid, fumaric acid, etc.) can effectively alleviate or reduce the adverse effects of heat stress.
Also do not forget about hygiene, disinfection and immunization work. It is necessary to promptly remove the excrement and dirt in the pens, keep the house clean and fresh, provide fresh air, provide a comfortable environment for the livestock and poultry, regularly disinfect the pens, eliminate pathogens, and eliminate potential hidden dangers; choose to be early or late or cool In the weather, do a good job of immunization of livestock and poultry to prevent the disease from taking advantage of deficiency and allow the livestock and poultry to survive the summer high temperature period.
