According to statistics, most of the losses and deaths of piglets after birth occurred within 30 days, and the deaths in the first week often accounted for about 60% of the total deaths. The reason is mainly because the newborn piglet was crushed to death by the sow, or due to improper feeding and management, or due to poor self-resistance, the occurrence of piglets jaundice, cold and other diseases caused by death. Obviously, it is very important to do a good job of raising and managing piglets in the first week after birth, which is the key to raising the piglet rearing rate.

Moisture anti-pressure. From the physiological characteristics of piglets, piglets are quite afraid of cold. Practice has proved that insulation is the key measure to improve the survival rate of piglets. The most suitable ambient temperature for piglets is: 1 day old -7 days old is 32°C-28°C; Insulation methods: Build a simple heat preservation room in the production circle. The infrared light bulb (250 watts - 500 watts) can be suspended in the holding room. In the middle of the insulation room, a dry and wet thermometer is suspended 0.5 meters from the bottom to accurately grasp the temperature and humidity. Put some short, loose grass on the indoor floor and pay attention to changing. After several trainings, the piglets will get used to getting into the heat preservation room automatically, so that the piglets will not be frozen to death, and they will rarely be crushed to death.

Eat colostrum. Because the newborn piglet does not have innate immunity, it must be obtained by sucking colostrum, otherwise it is prone to multiple diseases. In addition, colostrum is extremely rich in nutrients, contains a lot of protein, milk fat, high acidity, can meet the needs of piglets growth and development, early access to immunity and rich nutrition, increase resistance to disease. Infusion of 1 ml of Hengweikang (butiphos) into the weak AI daily for 3 days, increasing its vitality. A large piglet with a strong, arched breast is fixed to the back. Once the nipple is fixed, it will not change until weaning. If a small number of weak piglets are under sucking, supplemental feeding may be carried out to increase the survival rate of whole litter piglets.

Supplement iron selenium. Iron is a raw material for hematopoiesis. Iron deficiency in piglets can affect his own hematopoiesis. Newborn piglets have very little iron reserves, ranging from 30 mg to 50 mg. Their normal growth requires 7 mg to 8 mg of iron, and the amount available from breast milk is also limited. The piglet receives only 1 mg of milk per day from the milk. Iron, if iron is not added in time, piglets appear to have stung, and growth stagnates. In addition, iron deficiency selenium in piglets is prone to selenium-induced diarrhea, hepatic necrosis, white muscle disease, and edema disease. Therefore, piglets must be supplemented with selenium.

Overfeeding and merging. Those piglets that are not "mother" or milkless are appropriately adopted for feeding to other sows.

Strengthen care. Within one week after birth, the piglet is unresponsive and inflexible because of its unresponsiveness and is easily crushed to death. In order to prevent piglets from being crushed to death and trampling to death, sows should be provided with pressure-proof barriers, and regular inspections should be conducted to prevent starvation and death from freezing.

Prevent disease. In order to prevent the occurrence of pseudorabies in piglets in the future, after the piglets were born, the piglets were given a pseudonym vaccine once a day for two days and the piglets were given 1 ml of veterinary drips to supplement the necessary substances of the piglets and enhance the disease resistance of the piglets. In addition, the sows can be given drugs such as Zhifan San or oxytetracycline to prevent the piglets from developing red and jaundice.
