First, establish a high-yielding sow herd In a certain period of time, sows have different parity and the birth rate is significantly different. It is generally believed that reasonable sows in the herd have a sow structure with one to two sows accounting for 30% to 35% of sows, 6 to 60% for three to six, and 5% to 10% for more than seven children. . However, it should be decided according to breed reproductive performance, feeding and management level and other factors, such as the breeding ability of sows, high-grade sows can stay much more; at the same time, pay attention to the selection and retention of gilts. Second, strengthen the feeding and management of pregnant sows During the 75 days before pregnancy, due to the slow weight gain of uterine contents, the amount of feed should be controlled within 1.8 kg in order to avoid reabsorption of the fertilized eggs; during the 75 to 100 days of pregnancy, it is an important period for the development of sow's mammary glands. Excessive feeding can cause excessive fat deposition in the mammary gland and a decrease in the number of secretory cells in the milk, which leads to a decrease in lactation during lactation. Feed should be 2.0 to 2.3 kg; in the period of 100 to 112 days of pregnancy, due to the rapid growth of the fetus, The weight and fat deposition of the sow will be reduced. To ensure the good body condition of the sow and the birth weight of the fetus, the feeding amount should be increased to 3.3-3.5 kg at this stage. According to the immunization procedure, immunization with swine fever, swine blue-ear disease, pseudorabies, epidemic diarrhea, E. coli, Streptococcus, and other diseases is performed to ensure that the mother has a high level of antibodies, so that piglets are protected by sucking colostrum. In addition, sow prenatal care must be done. It is required to add somatotropin and florfenicol to the sow diet one week before birth to purify pathogens in the sow and reduce the chance of infection. Third, improve the nutritional status of nursing sows During the lactation period, the nutrient consumption of the sow is relatively large. It is necessary to optimize feed formulation and increase feed intake to ensure maternal nutritional needs, increase milk production, and improve milk quality. At the same time, close attention should be paid to the occurrence of postpartum arrhythmia syndrome. It is required to feed three full-fed nutritional feeds on a full-time basis and add moisture before feeding to increase palatability. Within 5 days after delivery, the amount of feed should be limited, and one week after birth, the supply should be kept open. At the peak of milk production, the feed intake per day of suckling sows can reach more than 7 kg. Within one week after birth, Kanggong San and Meiyisheng were added to the sow feed for reproductive system care; each sow was injected with 20 ml of long-acting oxytetracycline on the day of the farrowing, and the sow's reproductive tract was injected with Gong Yanqing. 20 to 30 ml to prevent postpartum infection and arrhythmia syndrome. Fourth, do a good job of nursing newborn piglets Pre-natal and post-natal strict disinfection to ensure that each piglet can eat colostrum, eat enough colostrum; at the same time, strengthen the cold and warm, according to the procedure of immunization, iron, selenium, to prevent anemia and diarrhea diarrhea. Strictly sterilize the surrounding environment, pens and utensils on the pig farm; set disinfection tanks or disinfection tanks at the door of the farrowing house to maintain effective drug concentration and strictly sterilize the pigs in and out of the premises; require the nursery to disinfect at least twice a week; Increase the number of disinfections when threatening. Before the birth of the piglet, 0.05% potassium permanganate warm water can be used to wash the sows' udder and vulva; the piglets tear the fetal membranes immediately after birth, dry the fetal fluid, and clean the fetal water and mucus in the mouth and nasal cavity of the piglets in time. Clean, so as not to inhale the lungs; the umbilical cord is ligated 2 to 3 centimeters away from the abdomen, and the umbilical cord must be sterilized with iodine, and those who are in a state of suspended animation must be rescued quickly to increase the number of live piglets. After drying the mucus from the piglets, the swine fever should be immunized immediately. Two piglets per piglet should be quickly placed in the incubator. After 1 hour, the pigs can receive milk. It is important not only to fix the nipple when feeding, but also to ensure that each pig can eat colostrum. At the same time, 5 litres of glucose can be given orally to weak piglets, and the weak piglets are fixed to the nipples with more milk in the front part of the sow. When the piglets are born, the total iron reserves are insufficient, and the iron content in the sow's milk is very small. The piglets should be injected with 150-200 mg of dextran iron at the age of 3 days. The lack of selenium in piglets not only can cause white muscle disease, perforation of diaphragm muscles, but also can induce E. coli disease, thus affecting the growth of piglets and even causing death. Generally, 1 ml of 0.1% sodium selenite is injected into each piglet at 7 days of age, which can effectively prevent white muscle disease and nutritional edema in piglets and promote piglet growth. At the age of two weeks, the maternal antibody was decreased, and her own immune system was not sound and it was easy to develop. In order to reduce the occurrence of diarrhoea and respiratory diseases and ensure robust growth, each piglet can be injected with 1 ml of long-acting oxytetracycline. 25 days of piglet immunization with swine fever, dose 4 heads; 32 days of immunization with foot-and-mouth disease, 2 ml dose; 39 days of age immunization with pig blue ear disease, 2 ml dose; one month later after a separate booster immunization The dose can be increased appropriately. Fifth, create a suitable living environment After the birth of the litter, the litter zone temperature should be guaranteed between 35°C and 37°C, and then every week thereafter, the temperature should drop between 2°C and 3°C. The optimum temperature of the litter in the litter must be controlled between 18°C ​​and 22°C. After the piglets are born, they should immediately provide a warm and small environment. In the piglet lying area, infrared light bulbs or electric heating plates can be installed. In the first two days of birth, the piglets should be adjusted to the incubator several times to make them into the warm box after eating milk. habit. Sixth, to lure ahead of time, force feed At 7 to 10 days of age, piglets like to bite harder objects. At this time, sweet granule feed can be used to induce piglets to feed as early as possible. Feeding should be carried out at the peak of piglet activity every day. The feed trough is located in a place where eye catcher piglets can be easily found, at 7:00 am to 9:00 am, 2:00 pm to 3 pm, and 7 pm at night. 9:00 Add feed during three periods of peak piglet activity. When the feeding effect is not good, the feed can be put into a paste and put in the mouth of the piglet. Each nest can be selected by several strong heads. Piglets have a strong imitation, and as long as a few litter pigs have a diet, other piglets can learn quickly. Piglets have the habit of not eating leftovers, and should be given as little as possible at the beginning, and should not exceed 50 grams per litter. The first day, even after eating, is no longer supplemented. The second day is slightly increased and gradually increased thereafter. Special attention should be paid to the fact that no feed can be added to the feed trough. Otherwise, the pigs will easily cause diarrhoea after eating too much food. Generally, the number of feeds should be increased from the age of 20 days, and should be reached 6 times per day when weaning. Feed more than 500 grams.
