First, increase primary birth weight and enhance resistance. Second, introduce an excellent breeding system and scientific breeding. Breeding sows of good breeds and large physique as commercial pig farms can increase the birth weight of piglets, perform reasonable hetero mating during the matching process, make full use of the advantages of hybridization, and prevent the mating of the smaller sized sows and sows. More weak and weak, so that its resistance, low immunity, increase mortality. Third, strengthen the management of feeding and raise the birth weight. Fourth, raising postpartum pigs to ensure milking power, post-harvest sow feeding and management is very important, is to protect the piglets, artificial feed intake can be controlled so that it provides the appropriate amount of milk to meet the needs of piglets. Fifth, piglets are heavily managed to increase their growth. Sixth to keep warm, reduce stress. The suitable temperature range for neonatal piglets is 29°C~34°C. As the age of piglets increases, the temperature requirement will decrease. 1 to 3 days of age is 30 to 34 degrees Celsius, 4 to 7 days of age is 28 to 30 degrees Celsius, and then falls 2 degrees per week until about 20 degrees Celsius. Seventh, early weaning. Implementation of early weaning can increase the reproductive rate of sows and the number of litters produced, reduce the production costs of piglets, increase the utilization rate of delivery rooms, and effectively control the disease. Early weaning generally refers to weaning on the 21st or 28th day. Eighth, strengthen health and epidemic prevention. In general, the sows can be selectively vaccinated with E. coli vaccine, mycoplasma, transmissible gastroenteritis, pasteurella, swine erysipelas, streptococcus suis, and rotavirus in the first 5 weeks before birth and 2 weeks before birth. This will enable sows to produce antibodies that are susceptible to the disease and produce a stronger protective effect on piglets.
