Pigs four key "one week"

One week after mating is the critical period of egg fertilization and fertilized egg splitting. If the sow is over-saturated at this time, part of the fertilized egg will die, which will reduce the number of litters. Therefore, sows should not be fed too much within one week after mating, and the daily feeding amount should be 1.5 to 1.8 kilograms, and no more than 2 kilograms.

Second, one week after childbirth

For first-born piglets, feeding and management one week after delivery is of utmost importance, as many casualties in the pig-raising process occur at this stage, such as freezing, frostbite, crushing, and death.

In order to reduce the piglet's death and injury rate during the week, the following tasks should be done: 1 Proper delivery of food 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.

Three weeks 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 has been driven off by the shepherd's temperature and maternal antibodies are stopped. 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 properly. Drug prevention is an effective supplementary measure to prevent secondary infections in piglets. Comfortable environmental conditions and quality feed are the guarantee for successful weaning.

IV. Week after 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 status in the new group through “competition”. At the same time, the three points of eating, pulling, and sleeping of the piglets are also completed this week. All these need to consume a lot of energy.

In order to allow the piglets to move smoothly, the following work should be done: 1 Bring the ambient temperature before the transfer to the new environment. 2 Feed the animals with the original feed for a period of time, and gradually reload them after the pigs have stabilized. 3 Strengthen drug prevention to prevent pathogens from invading the body of piglets. 4 There are often fighting phenomenon after mixed piglets. Therefore, for some strains with large stress response, attention must be paid to prevention when changing groups.
