1. Three days after breeding. Three days after mating, it is a critical period for egg fertilization and fertilized egg splitting. If the sow is over-saturated at this time, part of the fertilized eggs will die, which will reduce the number of litters. Therefore, the sows should not feed too much concentrate within three days of breeding. The daily feeding should be 1.5-1.8 kg, and no more than 2 kg.
2. Three days after childbirth. For newborn piglets, feeding and management are important for three days after giving birth. Because many casualty accidents in the pig-raising process have occurred at this stage, such as freezing, squeezing, death and death. In order to reduce the three-day mortality rate of piglets and lay a good foundation for future growth, the following tasks should be done: (1) Proper delivery and keeping warm. (2) Let the piglets eat colostrum in time to enhance their resistance to disease. (3) Fix the teat. This is an important measure to reduce the death of newborn piglets and increase the uniformity of the piglet population. (4) Timely iron supplementation and selenium supplementation to prevent selenium deficiency and iron deficiency. (5) Restore sow body condition, prevent postpartum infection, strengthen management in feeding, nursing, health care, etc. to make it through the period of physical weakness, and lay a good foundation for adequate and good weaning status of future milk production.
3. Three days after weaning. This is the period of most severe stress in weaned piglets: the food changes from liquid milk to solid feed; leaving the sow's care, while the sows are driven off by Sherwin's temperature; maternal antibodies are stopped. Reducing stress is the key to successful weaning of piglets. Drug prevention is an effective supplementary measure to prevent secondary infections in piglets. Comfortable environmental conditions and high quality, delicious feeds are the guarantee for successful weaning.
4. Three days after the transfer. The new feeding environment will cause the piglets to adapt physiologically and psychologically, and the disease resistance will also be reduced. The piglets of different nests will re-establish their position in this new group through “competitionâ€. At the same time, the three points of eating, pulling, and sleeping of the piglets are also completed in these three days, and these require a lot of energy. In order to ensure the smooth transfer of piglets, the following work should be done: (1) As far as possible, the environmental temperature of the transit group should be close to the new ambient temperature in order to reduce the stress. (2) Feeding with the original feed for a period of time until all the conditions of the herd are stable and gradually change to feed for the finishing period. (3) Strengthen drug prevention and prevent pathogens from invading the piglets. (4) Observe and observe emergencies in a timely manner. Fighting phenomenon occurs frequently after mixed piglets, and all varieties with greater stress response must be guarded during the transition.
