Due to physical and physiological factors, the feed of piglets is toxic at birth. The breeder should closely combine the characteristics of the growing period of piglets and put in balanced feed. While attaching importance to protein, we should also balance minerals, trace elements and vitamins. On the basis of high-quality feeding, ensure its high-quality growth quality and maximize management benefits. Piglets should be marked, weighed and cut off as soon as they are born. Inoculate in strict accordance with the immunization program, and supplement iron and selenium at the same time. The pigsty should be equipped with ventilation and insulation facilities. 2. Make an epidemic prevention plan.
Pay attention to specific immunity and nonspecific immunity to create group resistance. As a pig-raising enterprise, all the benefits come from health. In preventing piglet diarrhea, we must ensure effective prevention of swine fever, foot-and-mouth disease, pseudorabies, mycoplasma and infectious pleuropneumonia. Classical swine fever, foot-and-mouth disease and pseudorabies are the basis. Other vaccines, such as blue ear disease, Haemophilus parasuis, infectious gastroenteritis, epidemic diarrhea, Escherichia coli, red dysentery, etc., can be reasonably selected according to the situation in this field, and the effect is not very satisfactory.
3. Piglets are grouped
Before weaned piglets are transferred to the nursery, they should be divided into groups according to the overall situation of pigs, and groups with similar bodies should be selected. The principle is to keep the original nest as much as possible, and it is appropriate to group 7 ~ 10 head/group, and the feeding density should not be too large. It is necessary to spray a small dose of farmers behind the parallel column to prevent fighting. It is also necessary to train piglets in feeding and defecation. 7 ~ 14 days after weaning is very important, and it is necessary to continue to use the full-price feed at the beginning of feeding to adapt. Wait for it to adapt to the new environment before refueling. You can't replace them all at once, but you need to replace them step by step. Each replacement shall not exceed 1/3, and the replacement shall be continued for 2 ~ 3 days, and the later materials shall be replaced within 1 week. Special attention should be paid to adding vitamins, salts, minerals, glucose and other substances to the feed after weaning. At this time, it is best to maintain the temperature of the nursery at about 30℃, and gradually reduce it to 22 ~ 24℃ in the later period.
