The weather is getting warmer. It is a good season for raising pigs. Temperatures have risen and various germs have become active. After wintering of livestock and poultry, the body's resistance to disease has weakened. If the disinfection is not complete during the breeding process, improper management can easily cause pig disease and reduce the breeding efficiency. So, what problems should be paid attention to when raising pigs in the spring?
First, fix the pig house and do a good job of disinfection. Keeping the pig house warm, dry and ventilated, doing a good job in pig house hygiene, and often disinfecting pig pens to eliminate the germs' living environment is an important part of doing a good job of raising pigs in spring. Pigs prefer a warm and dry environment, especially the body's thermoregulatory function of piglets has not yet been fully developed, with less body fat deposition and poor cold resistance. In the early spring, the weather is fickle and there is a large temperature difference between day and night. Therefore, it is particularly important to keep the pig house warm, dry, clean and airy, and create a small environment conducive to the growth and development of pigs. Especially in the northern regions, the sows must be implemented with warm real estate, which is the basis for guaranteeing the piglets' full livelihood and full strength. At the same time, before the advent of spring, pighouses should be completely disinfected to prevent the growth and reproduction of germs. The specific approach is to first thoroughly clean the pens, and then use 20% to 30% of lime milk or 20% of the ash or 2% to 3% of the fire alkali solution to spray and brush the floor, walls and surrounding environment. After washing the equipment, use 3% to 5% of the water to disinfect the skin, and then rinse with water.
Second, strengthen the epidemic prevention and pay attention to nutrition. In the spring, we must guard against the occurrence of various infectious diseases. Strictly follow the immunization procedures for immunizing pigs. Once an epidemic has been discovered, it must be strictly blocked, disinfected, and the injections must be strengthened. The dead carcasses should be handled as required. If there is an outbreak in the surrounding area, besides the disinfection of the piggery, foreigners and vehicles should be strictly prohibited from entering the farm, and their vehicles and personnel must be completely disinfected after returning from the epidemic area. At the same time, the level of nutrition also has a major impact on the health of pigs. The high level of nutrient supply can meet the nutritional needs of pigs and ensure that pigs have a better body condition and can effectively improve their ability to resist diseases. Therefore, in the production of pigs should be based on different growth stages, scientifically fed a full price diet with different nutritional standards, and timely adjustment of diet formula based on changes in pig weight, eating conditions.
Spring green feed is lacking. It is necessary to add as much as possible juicy diets such as carrots and brewers' grains and cakes to increase the appetite of pigs and to supplement some vitamins.
Third, fine management, scientific feeding. Feeding and management of finishing pigs and breeding pigs can be carried out as usual, but the feeding and management of piglets must be done with caution. Because of the lack of innate immunity, body temperature regulation and digestive function of piglets are not perfect, in the spring of climate change, feeding and management are slightly wrong, can easily cause piglets to become ill, and even a large number of deaths. Therefore, it is necessary to improve the feeding and management of nursing sows, maintain the cleanliness and hygiene of the breasts, and ensure that the piglets pass through the first birth, feeding, and weaning passes in a safe and healthy manner. Good weaned piglets. Prevention of piglet dysentery should be vaccinated at the end of the sow's pregnancy, while paying attention to the sow's post-natal environment and the improvement of the pig's constitution. For pigs in each stage of feeding, pay attention only to feed the full-priced compound feed, and add appropriate amount of compound additives. Provide clean drinking water, adequate light and appropriate exercise to promote the healthy growth of pigs, so that pigs can safely spend the spring season of disease-prone.
