How to control the temperature of the farm at about 20-25 degrees in summer and the outdoor temperature at about 34 degrees.

Technical measures for heatstroke prevention and cooling in livestock and poultry farms

First, strengthen environmental temperature control. Build a shade shed or cover it on the top of the breeding pen, and build a shade shed on the window to prevent sunlight radiation; Arrange exercise time reasonably for some livestock and poultry that need sports ground to avoid high-intensity sunlight, and sprinkle water or spread grass (straw) with cement around the fence or sports ground to prevent sunlight reflection; Always open ventilation holes or doors and windows, and when conditions permit, use exhaust equipment to promote air circulation, increase air exchange and speed up indoor air flow; Take roof spraying, on-site spraying, installation of wet curtain and other ways to cool down; Strictly control the feeding density to avoid heat stress of livestock and poultry. Green plants should be planted around the farm, and the microclimate of the environment should be adjusted by dense planting, humidification and cooling.

Third, pay attention to adjusting the diet structure. Reasonably increase the proportion of protein in feed, appropriately reduce energy and increase the content of vitamins and minerals. Reasonable arrangement of feeding times and feeding time, preferably in the morning and evening, to ensure feed intake. Feed should be fresh, and it is forbidden to feed moldy and deteriorated feed. At the same time, baking soda, potassium chloride and vitamin C can be added to the feed to enhance the heat resistance of livestock and poultry, slow down heat stress, and add stomach-invigorating and digestion-promoting drugs as appropriate to promote the eating and digestion of livestock and poultry. Feeding more green and juicy feed is good for health and heatstroke prevention and cooling. Ensure enough cool drinking water, and the water quality is clean and hygienic.

Fourth, strengthen epidemic prevention and control. Strengthen the prevention and control of animal diseases such as highly pathogenic blue ear disease and streptococcus suis. We should do a good job in immunization against major animal diseases such as avian influenza, foot-and-mouth disease, classical swine fever and highly pathogenic porcine blue ear disease. For those who have exceeded the immune protection period or are not immunized, they should be supplemented as soon as possible and resolutely eliminate the immune gap. Strengthen the harmless treatment of dead livestock and poultry. It is strictly forbidden to discard dead animals and slaughter dead pigs at will, and it is strictly forbidden to eat dead pigs. Epidemic forecasting personnel at all levels should strengthen inspections, report abnormal situations in time, and avoid delaying the diagnosis and treatment of sick animals.

Fifth, strengthen daily supervision. Clean up the feces in time, replace the wet mat grass, and keep the fence cool and dry; Disinfect the whole site regularly and remove all kinds of production and living garbage in time; Reduce the feeding density appropriately; Livestock and poultry farms are forbidden to raise different kinds of animals, try to avoid domestic dogs moving freely in the field, and do a good job in killing rats, mosquitoes and flies to prevent the spread of diseases. When transporting livestock and poultry, the means of transport shall be equipped with sunshade facilities to reasonably control the density of livestock and poultry. It is best to transport it in the early morning or evening to prevent heatstroke. Once heatstroke is found in livestock and poultry, it should be treated in time. According to different breeds of livestock and poultry, measures such as cooling, bloodletting and rehydration can be taken for treatment.

Sixth, strengthen emergency preparedness. During the high temperature period, it is often accompanied by abnormal weather such as typhoon, rainstorm and even hail. All localities should guide all farm households to take precautions, maintain pens and strengthen fences, especially greenhouse farmers to strengthen sheds, clear ditches and drain water in advance to prevent heavy rains and strong winds. In addition, summer is often the peak period of electricity consumption. In view of the possible power outage, livestock and poultry farms with conditions should prepare generators as soon as possible, take the initiative to contact the local power supply department, master the power outage time, and get notice in advance to prevent the ventilation and cooling equipment from being unusable due to power outage, resulting in great losses.
