In the human body, there are many very crucial three days in the pig raising process. Under the premise of normal production management, the following “three days†will be paid attention to, which will result in a large increase in production performance. 1, three days after matching with three days, is the egg fertilization and fertilized egg split period, most afraid of sows metabolic hyperactivity, otherwise it will cause some fertilized eggs to die, thereby affecting the number of litters. Therefore, after three days of sow feeding, avoid feeding too much, the general daily dose of 1.5-1.8 kg, can not exceed 2 kg. 2. Three days after giving birth Three days after giving birth, it is the most critical three days in the life of a newborn piglet. The first death peak occurs at this stage. Starvation, freezing, crushing, death, etc. If you grasp the postnatal day for three days, you can greatly Reduce mortality. During these three days, the important tasks are: (1) Newborn piglet production and insulation. (2) Eat colostrum in time to enhance disease resistance. (3) Fix the teat, which is an important measure to reduce death and increase the uniformity of the piglets. (4) timely iron selenium to prevent selenium deficiency and anemia. (5) Restoring sow's body condition to prevent postpartum infection. Pay attention to feeding, nursing, health care, etc., to make it through the period of physical weakness, and lay a solid foundation for adequate milk production and good weaning condition. . 3, three days after weaning This is the most stressed period for weaned piglets, feed - liquid milk becomes solid material, temperature - after the sow drive away to reduce temperature, antibody - maternal antibodies to stop supplying, mood - - How sad it was to leave her mother for the first time. Each of these stresses will have a very adverse effect on the piglets and become the trigger for the disease. Reducing stress and buffering stress are the preconditions for crossing the weaning barrier. Drug prevention is an effective supplementary measure to prevent secondary infection. Comfortable environmental conditions and good quality feeds are the guarantee for successful weaning. 4. Moving into a new home three days after the group transfer will cause physical and mental incompatibility, regardless of whether it is good or bad. With unfamiliar partners, there are always a few unreasonable and resistant—maybe victory—but they consume a lot of energy and their resistance to disease declines; surrender is the object of bullying, and the conditions for food and shelter are not good. The new environment often has diseases that have never been seen before. Eating and sleeping three positions must be completed in the first three days. Therefore, the following work should be done to ensure a smooth transition after the transition: (1) Close the temperature difference and make the original ambient temperature and the new ambient temperature as close as possible, especially in the winter. This is very important. (2) Maintain the original feed and gradually transition to a new feed. (3) Drug prevention to prevent the invasion of pathogens. (4) Pay attention to observation and handle emergencies in time. After the piglets are mixed, they often suffer from fighting and often suffer from death. Therefore, for some strains with high stress, care must be taken when switching to groups. The above is just a brief introduction of several more important three days. There are still many similar places in production. I hope to discuss with peers and communicate with each other to improve pig production performance.
