The method of scientific feeding newborn pigs

In the process of raising live pigs, pig feeding is a key stage in the whole production process, especially newborn pigs, if they do not take active protection, the mortality rate can be as high as 50%. If we can get through this dangerous period, the survival rate of pigs can be greatly improved. so as to improve the efficiency of pig production.

Strengthen feeding and management to improve the resistance of pigs

(1) the delivery house should do well in environmental hygiene and pay attention to disinfection. Before entering the delivery room, the sows should clean the delivery room and disinfect the floor, walls and fences with the relevant disinfectant. When the walls, doors and windows are damaged, they should be repaired to prevent thieves and keep good temperature and humidity. The ground should be smooth and check whether the functions of incubator, heating lamp, nozzle and feeding trough are normal at the same time.

(2) the sows were "attenuated" before delivery. From 85 days of late pregnancy to 5 ~ 7 days before delivery, sows were attenuated with relevant sensitive drugs. mainly to blue ear disease, circovirus infection, reproductive disorders of classical swine fever, pseudorabies, mycoform infection and other pathogens transmitted or complicated by mother and child "in advance treatment", reduce the incidence, and do a good job of anti-stress in the late pregnancy to prevent abortion. Recommended program: 30 days before delivery with compound Timi Pioneer + antiviral I powder + water-soluble amoxicillin 300ppm for 15 days; at the same time, Fuhong Changxiao (long-acting oxytetracycline 0.2ml / kg w) was injected into sows one week before and after parturition to prevent and cure triple syndrome of sows (uterine inflammation-mastitis-no milk syndrome).

Sows should be immunized with related vaccines 40 days before delivery, such as Escherichia coli vaccine, porcine red dysentery, atrophic rhinitis, pseudorabies and so on. Qingkailing injection should be injected once or twice before and after immunization to improve immunity and relieve immune stress.

(3) the pigs should drink enough water. At the age of 3 to 5 days, pigs should be supplemented with clean drinking water, such as 20 kg of glucose, 2 g of sodium bicarbonate and 0.06 g of vitamins.

(4) pay attention to midwifery, keep warm and prevent pressure in time after birth, break umbilical cord, cut teeth and tail, eat colostrum, fix nipple, number and so on. Before feeding the newborn pig, it is necessary to wash the nipple with 0.1% potassium permanganate or normal saline, and let the pig suck after squeezing the milk, so that the pig can quickly obtain maternal antibodies.

(5) three doses of long-acting oxytetracycline were given to pigs at 1 day, 7 days and 21 days after birth. 0.5 ml of long-acting oxytetracycline was injected at 1 day old, 0.6 ml at 7 days old and 2 ml at 21 days old. It can effectively prevent diarrhea and early respiratory syndrome and significantly improve the survival rate of pigs.

(6) Zi pigs are supplemented with iron and selenium. The pigs were intramuscularly injected with 1 ml of bovine hemin 3 days after birth, supplemented with selenium from 3 days to 5 days, 0.5 ml of 0.1% sodium selenite and vitamin E 0.5 ml intramuscularly, and once more before weaning. This can prevent dysentery, white muscle disease, nutritional anemia and so on.

Strengthen the work of heat preservation and pressure prevention

The death of newborn pigs due to supine pressure in sows accounts for about 20% of non-infectious deaths. Increasing temperature and replenishing energy can reduce this phenomenon.

Let the pig eat colostrum as soon as possible.

Increase the nutrition of sows

In addition to normal feeding, the nutrition supply of sows should be strengthened and short-term preferential feeding should be carried out in the later stage of pregnancy. For example, each head is fed more than 1 kg of mixed concentrate per day or animal fat or vegetable oil (accounting for 5%-6% of the diet) is added to the original diet to help improve the birth weight and survival rate of piglets; fat supplementation also helps to improve the fat content of colostrum and regular milk. The addition of vitamin C to the diet of sows one week before parturition can greatly reduce the umbilical cord hemorrhage and mortality in piglets.
