Winter pigs pay attention to what issues
With the onset of winter, the external climate has undergone tremendous changes. Cold weather will cause severe cold stress on the pigs. If the management is not strengthened, pigs will slow down the growth rate or develop diseases, which will have a great impact on pig production. . The reporter interviewed the experts of the expert advisory group of the newspaper about the feeding and management of winter pigs. Experts pointed out that in the winter feeding and management, the following four points should be achieved.
First, repair the pig house. Before the cold winter arrives, the pig house should be completely overhauled and maintained, repairing the damaged housing, walls and ceiling. In order to increase the effect of heat preservation, open-type pig houses should be built with plastic insulation sheds, and the windows and extra vents should be sealed. Cotton curtains and straw curtains should be hung at the entrance to prevent cold wind from entering.
Second, keep the house clean, dry and fresh air. In order to keep warm in winter, the ventilation intensity will be reduced and the humidity inside the house will be too high, as well as excessive harmful gas stagnation. Excessively high indoor humidity and excessive harmful gases can cause respiratory diseases and other diseases in pigs. Therefore, it is necessary to frequently remove house excrement, maintain a good hygienic environment, reduce the humidity in the house, and reduce the harmful effects caused by the accumulation of faeces. Gas concentration. Under the premise of maintaining the temperature, the ventilation volume should be increased to keep the air in the house fresh and reduce the incidence of respiratory diseases induced by harmful gases.
Third, increase the temperature inside the house. Too low temperature will bring severe cold stress to the pigs. The cold stress will reduce the health of the pigs and induce some diseases, especially the pigs. The cold environment will make the pigs diarrhea. Intensification, resulting in increased mortality of the piglet. There are many ways to increase temperature, such as using hot blast stoves, coal stoves, heating and other equipment to provide heat sources to increase the temperature, but also to increase the stocking density appropriately, and to increase the shepherding temperature by the distribution of the herd's own temperature (for fattening Pig) etc.
Fourth, feeding high quality diets to improve feeding methods. In the cold winter, it is particularly important to provide a complete diet for the pigs. Farmers can rationally select suitable premixes for pigs of all ages based on the weight of their pigs. Ice-chilled feed has a greater impact on the pigs during the winter season. Feed as much as possible with dry powder, or use warm and hot water condiments to feed, if possible, provide clean, warm water for pigs to drink freely. In winter, when the pigs are short and long nights, the pigs have a fasting time in the evening and they should be fed an overnight diet at night so that the pigs can eat enough nutritious and comprehensive diets to facilitate the increase of daily weight gain and shorten the feeding cycle.
