How to keep pigs safe for winter
In recent years, many pig farmers have been plagued by the safe wintering of pigs, but no effective method has been found yet. Not long ago, the author went to the country to interview and found that the experience of “producing herds safely overwintering†by Tian Baoyu, a farmer at Jiangbin Farm in Luobei County, was worth promoting. 1, taboo open-air breeding, keep pigs warm. According to seasonal weather changes, precautions should be taken in advance, such as the installation of doors, windows, roof repairs, and heating appliances before the winter. The suitable temperature of the pig house is about 1 to 10 days old at 26°C; the pighouse temperature at which the piglets are to be weaned is kept at about 20°C; the pighouse temperature of the middle-aged pigs should be maintained at 16°C or more. Commonly used heating methods are simple stoves, fire pits, fire walls and so on. 2, do a good job in pig house disinfection and immunization work. Some infectious diseases have obvious seasonality, such as porcine contagious pneumonia, swine flu, and epidemic diarrhea, which can be induced by sudden changes in climate and poor hygiene conditions. Before the winter, the pig house was once sterilized. It is best to use air fresheners in the air to disinfect the house (pay attention to places away from pigs feeding and drinking to prevent pigs from eating food poisoning). It can also be sterilized and disinfected in the piggery by means of igniting the plant Artemisia halodendron by means of sterilizing and disinfecting, suspending bagged white ash in the air, and scattering white ash in corners. Disinfection work should be carried out once a month. Ventilation after disinfection should be done regardless of disinfection. In addition, we must pay attention to the scientific feeding requirements, regular injections of injections to prevent infection of other diseases. 3, adjust the feed formula. In the cold season, it is necessary to increase energy standards for diets, such as adding fats and proteins to piglets and lactating sows; increasing the amount of vitamin additives and adding preventive drugs such as vitamins and salinomycin to prevent piglets from developing dysentery. Improve the weight gain of piglets has a better effect. 4. In the winter and winter season, the daily feeding amount and daily feeding times of various types of pigs should be increased. For lactating sows and pre- and post-weaning piglets, feeds with higher protein feeds are added once or twice a day to increase cold resistance, increase milking power of sows and growth rate of piglets.
