Five key points of raising pigs in spring

The peasant proverb said, "Peach blossoms lead to pig disease." Yangchun March, the weather is getting warmer, is a good season for raising pigs, but at this time the weather is changeable, a variety of bacteria multiply and grow in large numbers, such as incomplete disinfection, mismanagement and poor feeding, which can easily lead to pig disease. Therefore, to raise pigs well in spring, the prevention and control of epidemic disease is particularly important.

1. Repair and disinfect the pig house.

Disinfect the living environment of germs. Pigs like a dry environment, especially the thermoregulatory function of piglets is not yet well developed, less fat is deposited on the body surface, and the cold resistance is poor. On the other hand, the weather in early spring and March is suddenly sunny and overcast, and the temperature difference between day and night is large. In addition, it is said that it is cold in late spring, so it is particularly important to plug loopholes, close the shed, hang the door curtain, maintain the temperature of the pigsty, dry and clean environment, smooth air, and create an environment conducive to the growth and development of piglets. Post-parturient sows should give birth in greenhouse.

At the same time, before the advent of spring, pig houses should be thoroughly disinfected to prevent the growth and reproduction of germs. To clean the enclosure, spray and brush the enclosure floor, strong wall and surrounding environment with 20% murine 30% lime milk or 20% wood ash or 2% Mustang 3% caustic soda solution, strictly disinfect the utensils with 3% Mui 5% laisuer, and then rinse with water, so as not to cause poisoning or affect the feed intake of pigs.

2. Strengthen epidemic prevention

In spring, it is necessary to prevent the occurrence of infectious diseases such as classical swine fever, erysipelas and lung disease. Farmers should do a good job of immunizing pigs in strict accordance with the immunization procedure. Avoid missed injections, vaccine failure and other situations. In the event of an epidemic disease, we should strictly block disinfection, strengthen preventive injections, and dispose of dead pig carcasses as required. There is an epidemic around. In addition to disinfection in pig houses, pedestrians and vehicles from outside are strictly prohibited from entering pig farms. Their vehicles and personnel should be thoroughly disinfected when they come back from the epidemic area.

3. Pay attention to nutrition supply and adjust feed formula

According to the different growth stages of pigs, the full-price diets with different nutrition standards should be fed scientifically, and the diet formula should be adjusted timely according to the body weight and feeding conditions of pigs. Lack of green feed in spring, try to add some succulent feed such as carrots and brewer's grains and cake feed in the diet to promote the appetite of pigs and supplement some vitamins at the same time. Only when pigs are in good condition can they enhance their disease resistance and make them grow rapidly.

4. Fine management and scientific feeding

In the spring with changeable climate, piglets tend to lack innate immunity, and their thermoregulation function and digestive function are not perfect. If there is a slight error in feeding and management, it is very easy to cause piglets to get sick and even die in large numbers. Therefore, it is necessary to improve the feed of lactating sows to ensure the cleanliness and hygiene of the breasts, to do a good job in the three links of feeding, supplementary feeding and vigorous feeding, and to safely pass the birth, replenishment and weaning, and special care should be given to weaned piglets; the prevention of dysentery in piglets should be vaccinated in the later stage of pregnancy, pay attention to the cleanliness of the environment and improve the physique of piglets after delivery. Feed compound additives, bask in the sun more, do more activities, promote the growth of piglets and get through the spring safely.

5. Feed healthy traditional Chinese medicine to enhance the disease resistance of pigs.

The traditional Chinese medicine of expelling wind and dispelling cold, strengthening muscles and bones, moistening the lung and relieving asthma is used in the feed to strengthen the upright and dispel evil, enhance the resistance of pigs, prevent disease and promote it. The prescription is: 30 grams of Schizonepeta tenuifolia, 30 grams of forsythia, 30 grams of honeysuckle, 30 grams of Fangfeng, 25 grams of Ephedra, Atractylodes, 25 grams of cassia twig, 15 grams of Sichuan dome, Radix Paeoniae Rubra, Radix Atractylodis, 15 grams of almond, 10 grams of hay, and 10 grams of hay.
