The key three days of raising pigs
There are many key “three days†in the key three-day pig raising process. In this period, strengthening the husbandry and management will greatly increase the production efficiency. 1. Three days after mating, 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 and the number of litters will be reduced. Therefore, sows should not feed too much within three days after mating, and the daily feeding amount should be 1.5 kg to 1.8 kg, and no more than 2 kg. 2. Three days after giving birth For newborn piglets, feeding and management after three days of delivery are very important because many casualty accidents during the pig raising process occur at this stage, such as freezing, frostbite, crushing, death, etc. . In order to reduce the death and injury rate of piglets in these three days and lay a good foundation for their future growth and development, the following tasks should be done: 1 Proper delivery and protection against moisture. 2 Let the newborn pigs eat colostrum in time to enhance disease resistance. 3 fixed teats. This is an important measure to reduce the death of newborn piglets and increase the uniformity of the piglet population. 4 Timely iron and selenium supplements to prevent selenium deficiency and anemia. 5 Restore sow body condition to prevent postpartum infection. Strengthen management in feeding, nursing, and health care so that it can successfully pass through the period of physical weakness, and lay a good foundation for adequate milk production and good weaning status in the future. 3. Three days after weaning This is the most severe period of stress in weaned piglets: the imported food is changed from liquid milk to solid feed, leaving the sow's care, and at the same time, the sow is greatly reduced due to shedding of the sow. Antibody stops supplying. Each of the above stresses will have a very adverse effect on the piglet and become a cause of its onset. Reducing stress is the key to helping piglets to wean safely. Drug prevention is an effective supplementary measure to prevent secondary infections in piglets. Comfortable environmental conditions and good quality feeds are the guarantee for successful weaning. 4. The new feeding environment for three days after the colony will cause the piglets to adapt physiologically and psychologically, and the disease resistance will also be reduced. The piglets with different nests will re-establish their status in the 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. All of these need to consume a lot of energy. In order to ensure the smooth transfer of piglets, the following work should be done: 1 As much as possible to bring the temperature of the environment before the transfer to the new environment, especially in the winter, to reduce stress. 2 Feed with the original feed for a period of time until all the pigs have stabilized and gradually change to fattening feed. 3 Strengthen drug prevention to prevent pathogens from invading the body of piglets. 4 Observe and deal with emergencies in time. Fighting occurs frequently after piglets are mixed. Therefore, for some strains with a relatively high stress response, attention must be paid to the precautions when changing groups.
