Through years of work experience, the author believes that the reasons for the low survival rate of self-producing and self-sustaining piglets are mainly the following aspects.
1. Improper feeding and management of pregnant sows cause piglets to be congenitally stunted and present with weak, teratogenic, stillbirth, etc.; sows with postpartum frail and lack of milk, piglets hunger due to hunger, long time around the sow, chaotic arch, resulting in There is a greater probability of death by pressing on hunger (10% to 20%).
2. Death caused by disease Caused by the sow's own reproductive disorder syndrome (pseudorabies, blue ear disease, parvovirus, chronic swine fever, etc.) infection, it is difficult for piglets to overcome the threat of congenital disease, resulting in shortly after birth Death occurred. The environment of the acquired piglets is seriously polluted, and infected piglets such as red warts, jaundice, white diarrhea, edema, and blue-ear disease have died.
3. Insufficient digestive function of piglets Piglets have no free hydrochloric acid in the stomach (sterilization, assisted digestion) and lack of innate immunity. They can only produce immunity after eating colostrum (newborn piglets can directly absorb immunoglobulin from breast milk and gain immunity. (Antibodies). Therefore, piglets are prone to die of diarrhoea due to infection with bacteria and viruses in the early stage of the piglets.
4. The ability of the piglets to regulate body temperature is often low because of the low ambient temperature (mostly at 15 °C ~ 20 °C). When the temperature in the delivery room is low, the piglets cannot find a source of heating, and the piglet will be under the tummy of the sow or Drill inside the leg and cause pressure to die.
5. Insufficient heat preservation and feeding methods for piglets In order to solve the problem of low ambient temperature of piglets, some rearing households have adopted piglets that are fed every 2 hours, and then caught the piglets in boxes or baskets, causing the temperatures in the boxes or baskets to reach 30°C. Above, the difference between the temperature of the sucking milk is 15°C or more, so that repeated stimulation of large temperature difference easily leads to cold death of piglets.
6. Improper feeding due to poor feeding and management conditions and lack of responsibility. Deaths such as being trampled, crushed, frozen, killed, etc. also occupy a certain percentage.
7. Iron-deficient anaemia pigs have only about 40mg of iron reserve after birth, 7-8mg of iron per day for metabolism, and 1mg of iron per day for breast milk. Therefore, piglets should take iron supplements 3 to 4 days after birth. A one-time injection of 150mg, but the rural free-ranging household pigs, do not know to feed piglets in time, each year due to iron deficiency anemia accounted for a certain proportion of deaths.
For the above reasons, we formulate countermeasures accordingly and have a good effect on improving the survival rate of piglets.
Total parenteral nutrition refers to contain the human body the necessary nutrient solution in the form of concentrated outside of the gastrointestinal tract by is the veins around the gastrointestinal tract into the blood for the blood circulation and can help those patients with dyspepsia compensatory nutrition to prevent and correct the malnutrition enhance body immunity.
Specialist devices for patients after surgery. It is a kit set, including two radial connectors (one blue and one white, also them as pagoda Connector), one cornical connector (transparent), and three threaded Luer locks. Six of them are universally used to slove all the turing connection problems after surgery. Using them, no need worrying about leakage, disconnection, size dismatching and others. For blue pagoda connector, it suits with the tubing diameter more than 16Fr, and the white one are applied with the tubings from 3Fr to 16Fr.
