It will be.
Pig hypothermia is manifested as a sudden onset, body temperature 35℃-37℃, obvious loss of appetite or even do not eat, depressed spirit, especially serious will also appear unable to stand, anal relaxation, rectal prolapse, etc., sick pigs generally have no other history. If left untreated or treated improperly, it can lead to death.
pathogenesis
1, pig house, temperature change and other reasons make it difficult for pigs to adapt to the temperature drop. Mostly in weak, rural free-range straps or late pregnancy sows; Long-term wet ground or long-term feeding of flour; Sows drinking cold water have higher incidence;
2, improper feeding management and climate environment and other factors, such as low feed protein content or improper feed mix; Cause energy metabolism disorder, the body can not maintain normal physical fitness resulting in low temperature;
3. Severe bleeding caused by trauma leads to insufficient blood supply and low temperature;
4, the use of antipyretic drugs is improper (generally excessive), the drug stimulates the warm nerve, causing the body to appear low temperature symptoms. Such as acetaminophen, acetaminophen, andadin, etc. can cause low temperatures.
5, endotoxin effect, pig gastrointestinal movement weakened, unable to completely discharge endotoxin resulting in low temperature;
6. Low temperature caused by poisoning after pesticide ingestion or mildew of premix, corn, soybean meal, etc. In severe cases, there are obvious symptoms, such as foaming at the mouth, opisthotropis, etc., but most of them only show temperature drop and appetite loss;
7, pathogen infection, due to the pathogen into the body has not been effectively controlled, the formation of bacteremia or toxemia, generally manifested as early temperature rise, late temperature drop;
8, surgery can also cause low temperature, such as castration, umbilical hernia and other operations using anesthetics, disinfectants, body cavity irrigation or excessive blood loss during the operation and other causes of body temperature drop, generally without special symptoms.
principle of treatment
This disease should be early detection and early treatment, in order to strengthen the feeding management, rehydrate, strengthen the heart, restore the normal regulatory function of the nervous system, mainly tonifying qi, the use of traditional Chinese medicine and western medicine combined treatment principle.
traditional Chinese medicine therapy
Codonginseng, Huangmao, cinnamon, cooked aconite 25g each, dried ginger, grass fruit, forsythia, licorice 15g each, a total of ground into fine powder, with boiling water and add an appropriate amount of brown sugar, after the temperature of the sick pig. Add 1000 ml of water to the medicine, decocted to 500 ml, once swallowed, 1 dose a day, even take 3 doses. Intramuscularly inject adenosine triphosphate 50-100 mg once a day for 3-5 days.
