Keeping the pig house warm is not just about heating the pig house
In the south, another cold winter ushered in. The temperature in Guangdong, Guangdong, Fujian, Jiangsu, Zhejiang, Jiangxi and other places has recently dropped to the lowest temperature since winter. Frost and icing have occurred in some places (frozen in northern Guangdong), and the pig farm is greatly affected by the temperature drop. . According to reporters, some smaller pig farms in the south usually use heat lamps to keep warm, but in the face of very cold, heat lamps are obviously not enough, so some large-scale pig farms with better equipment have also begun Use pig house heating boiler.
For the south, the cold climate time is not as long as that of the north. Therefore, considering the cost of the farm, additional temporary heating measures can be added when encountering particularly cold weather, such as some oil-fired electric heating, and an external heat source Wait. According to the reporter, the addition of a heating boiler in the piggery will ensure that the temperature in the piggery is about 22 ° C when the outdoor temperature is about 5 ° C.
In addition, the current warmth of the farm is more influenced by the design of the farm. For example, some pig farms implement the elevated bed model. The pig bed is 2. 8 meters high from the ground, so that it is easy to enter the "thief wind" from under the leaky floor, and the space under the pig bed The bigger the wind speed, the faster the insulation will be than the traditional pig house. When the wind speed of the thief wind is 0. 15 m / s, the actual temperature experienced by the pig decreases by 4 ° C, and the greater the wind speed, the colder it becomes. The piggery should close the doors and windows, put down the roller blinds, block the air leaks, and often inspect regularly to prevent the plastic roller blinds from leaking.
On the other hand, the good news is that with the adjustment of breeding density and the improvement of detailed management, diarrhea has not experienced a large-scale outbreak as in previous years, and it has mainly shifted to distribution. Fattening pigs can play a warming role by appropriately increasing the feeding density.
In keeping the pig farm warm, management and details should also be emphasized, the relevant assessment system should be improved, and the breeder's sense of responsibility should be improved. Properly adjust the density of the tour in cold climates and correctly assess whether the pigs are in a comfortable state. Especially the current temperature in the southern region is cold in the morning and evening. Keeping warm is not a matter of turning on the pig house heating boiler. The temperature adjustment and ventilation control should be based on the status of the pig, and the breeder should carefully control it. For example, the piggery heating boiler is used for heating in the morning and evening when it is cold, and the heat preservation lamp is used when the temperature is high during the day.
