The temperature rise in spring is the season of piglets production, but due to factors such as high and low temperature, large temperature difference, etc., the survival rate of piglets is affected. Therefore, we must pay attention to the following nine points. First, make good preparations before birth. Care must be taken to ensure that the sows’ udders, nipples, and vulva are cleaned and disinfected before delivery, and that the birthing or bed and incubator are sterilized. The sow is fed a small amount of feed or not on the day of delivery to prevent the sow from overfeeding and affect the piglet's output. In addition, prepare iodine, ligatures, scissors and other tools. Second, pay attention to insulation, cold. The optimum temperature for newborn piglets is: 1 day to 3 days old 30°C to 32°C, 4 days old to 7 days old 28°C to 30°C, 8 days old to 14 days old 25°C to 28°C, 15 days old~ 30-day-old 22°C～25°C, 31-day-old and split-living maintained at 22°C. Winter and spring seasons should pay special attention to cold and warmth. Before sow littering, the farrowing box should reach the required temperature of 30°C～32°C. Piglets have a comfortable temperature environment. Third, pick up good production. When the sow is in litter, the breeder must be present. After the birth of the piglet, wipe the mucus out of the mouth with a towel in time to allow it to breathe normally. Then wipe the entire body. Then cut the umbilical cord from 3 cm to 4 cm away from the navel of the piglet. Apply iodine and place in an incubator. For suspended piglets, first aid can be given by rubbing the nose with a stimulant such as alcohol or by acupuncture. Fourth, piglets should eat colostrum. Colostrum is crucial for the disease resistance, disease prevention and survival of piglets. The piglets should be allowed to eat colostrum as soon as possible, and artificial supplements should be given to weak piglets to increase their physical strength, restore body temperature, and supplement water. Fifth, fixed teats. Fixed nipples should adhere to the principle of “mainly self-selected, appropriate adjustment, and controlling strong and weakâ€. The method is: let the piglets choose their own nipples first, and then adjust according to the size of the body and the strength of the body. Usually, the weak piglets are placed in the sows. The middle front nipple sucks the milk, and it is firmly fixed in the back so that the litter of the litter can grow neatly without stiff pigs, and the piglets can avoid nipping the nipple in order to compete for nipples. Sixth, early feeding. At the age of 7 to 10 days, put a little fresh and clean pig farm material into the feed tank of the piglet to attract food, and put the piglet on clean ground to allow the piglet to imitate sow feeding and feeding. The amount should be as low as possible, and it is guaranteed that the piglets are fresh every day. 7. Observe carefully. Within five days of the birth of the piglet, special nurses should be on duty in rotation to observe the growth, feeding, feeding, and droppings of piglets at any time. If piglets are found to be thin, they must be supplemented with appropriate concentrates to find that the piglets are diarrhea or do not eat. For diagnosis and treatment, the number of piglets should also be carefully counted so as to prevent the sow from squeezing the piglets. Eighth, prevention of disease. The first thing is to prevent the epidemic After the piglet has processed the umbilical cord and wiped off the mucus, a single dose of swine fever was injected intramuscularly, one dose (150 immunization units), and colostrum was eaten after one hour. The second is to prevent anemia. 2 ml of iron-cobalt dextran injection can be used intramuscularly at 3 days of age. Third, we must prevent squatting. First of all, sows are injected with yellow and white piglets multi-valent seedlings 15 days prior to sow's birth; followed by keeping the pens clean and sanitized and often disinfected to prevent piglets from drinking filthy water. Fourth, prevention of postpartum diseases in sows. Observe the sow’s breathing, body temperature, feces, and breasts in a timely manner to prevent postpartum disease and affect lactation and piglet growth. Five must be disinfected. Each month, 100 pig poisons, ABB, 1210 and other disinfectants are used to disinfect pig houses and utensils. Nine, cut off milk. Normally weaning can be done after 30 days of age. It is best to adopt the method of weaning without weaning and try to achieve the same feed, environment, and management in order to prevent stress reactions in piglets. Later management, environment, and feed should gradually Improve so that the piglet has an adaptation process.
