It is forbidden to throw cold water on pigs in the middle of summer.
The temperature is high in midsummer, and pigs are often hot and gasping for breath. Some farmers are worried that the pig will have a fever problem, so they throw cold water on the pig in order to cool it down and make the pig feel more comfortable, but they do not realize that this is harmful rather than beneficial. Hot panting of pigs is caused by poor perspiration and lack of heat in the body for a while. If cold water is thrown on the pig at this time, due to strong cold stimulation, the sweat pores of the pig's whole body contract sharply, the heat in the body is blocked, and the body temperature rises abruptly, causing high fever and inflammation of the lungs in the pig, and death in the pig. therefore

Interferon can reduce the mortality of pigs with blue ear disease.
Interferon is a kind of protein with antiviral, anti-tumor and immunomodulatory functions induced by a variety of inducers (viruses, bacteria and macromolecules, etc.). In order to explore the therapeutic effect of interferon on porcine blue ear disease, we conducted an experiment on the efficacy of interferon combined with other drugs in the treatment of porcine blue ear disease from August to October 2006. From August to October 2006, 325 pigs with blue ear disease diagnosed by laboratory diagnosis were selected from the animal clinic of Huaian Animal Husbandry and Veterinary Station.

Treatment of calcium and phosphorus Metabolism Disorder in Pigs with combination of traditional Chinese and Western Medicine
Calcium and phosphorus metabolic disorders occur in young pigs, resulting in bone dystrophy called rickets. The pathological features were insufficient calcification of osteoblasts and temporary calcification of persistent cartilage hypertrophy and epiphyseal enlargement. The clinical features are digestive disorder, heterophobia, lameness and bone deformation. It is a non-inflammatory disease of bone tissue dysplasia. Vitamin D deficiency also plays an important role in the pathogenesis of rickets. Calcium and phosphorus metabolic disorders occur in adult pigs, resulting in osteodystrophy called osteomalacia, or fibrous osteodystrophy. The pathological feature is the progression of bone

Chicken infectious anemia-symptoms
Under natural conditions, the incubation period of the disease is not very clear, but the earliest 12 days can show clinical symptoms, and the death rate increased in the 3rd-# 61566th week. Anemia and tissue lesions occurred 8 days after artificial infection of 1-day-old chicks, and the disease began to occur on the 10th day & # 61566 ~ # 14 days, and then died. Anemia is the characteristic symptom of this disease. 14 days after infection, anemia was the most serious and hematocrit decreased to less than 20% on the 16th day. Sick chickens show disgust.
