There are several key “three days†in the management of sows and piglets. For example, breeding, tillering, weaning, and the first 3 days after transfer are important turning points that determine the normal growth and development of pigs. Pay attention. In production, we must seek for advantages and avoid disadvantages, and do a good job of nursing care focusing on health care to reduce the impact of various unfavorable factors and increase the breeding rate of sows, the survival rate of piglets, and the comprehensive benefits of raising pigs.
Three days after mating, the sow is the critical period for 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 be kept quiet and rested within 3 days after mating, and should not be fed too much. The daily feeding amount should be 1.5-1.8 kilograms, and no more than 2 kilograms, so as to ensure the success rate of breeding and the efficiency of fertilization. Increase litter size.
Three days after the third day of farrowing, the sows are born and dying for three days after birth, because if these three days are poorly managed, they are prone to frostbite, frostbite, crushed death, and death. In order to reduce the piglet's death and injury rate during these 3 days, the following tasks should be carefully done: 1 Proper delivery and protection against moisture. 2 Let the newborn pigs eat colostrum in time to increase the disease resistance. 3 Fixed nipples to prevent bullying, in order to reduce the death of newborn piglets and increase the uniformity of piglets. 4 Timely iron and selenium supplements to prevent selenium deficiency and anemia. 5 To strengthen the postpartum nutrition of sows, restore the sow's constitution as soon as possible, and prevent postpartum infection.
Three days after weaning 3 days after weaning was the most intense period of piglet stress, from feeding breast milk to feeding solid feed and leaving the sow warm, various ecological conditions changed, and the temperature was reduced greatly. Antibody stops supplying. Each of the above stresses will have a very adverse effect on the piglet and become its cause of morbidity. Therefore, pay attention to meticulous care and reduce stress as much as possible. On the one hand, we must create comfortable environmental conditions, provide quality feed to help weaned piglets, and on the other hand take effective preventive measures such as drug prevention to prevent secondary infections of piglets. To ensure that the piglet is weaned successfully.
After 3 days of transfer, the piglets will be transferred to the colony. The new feeding environment will cause the physiological and behavioral maladjustment of piglets, and the resistance to disease will also be reduced. After nestlings of different litters, they will re-establish their relationships with each other in this new group through self-adaptive adjustment. At the same time, the three points of eating, pulling, and sleeping of the piglets are also completed in these three days. These need to be consumed. A lot of energy.
In order to ensure the successful transfer of piglets, the following points should be carefully done: 1 As much as possible to bring the ambient temperature around the transition group closer. 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 After the piglets are mixed, the fighting phenomenon often occurs. Therefore, for some varieties with greater stress response, special attention should be paid when switching to groups and strict precautions should be taken to avoid all kinds of undue injuries.
