Diagnosis and Treatment of Acute Selenium Poisoning in Pigs
1 Incidence and Clinical Symptoms In November 2002, a specialized pig-farming household in Wuhua County, Guangdong, raised a total of 20 piglets from the same litter. The sow's milk was sufficient, the piglets nursed normally, and they grew well; at 10 days of age, each weighed about 1.5-2 kg. The owner injected each pig intramuscularly with 2 ml of sodium selenite vitamin E injection. On the morning of the next day, 2 pigs were depressed, unwilling to walk, refused to nurse, urinated frequently while standing, with a small volume and in a painful manner, had rapid and labored breathing, walked as if drunk, wandered aimlessly, and bumped their heads against walls or circled.

What is selenium, cobalt and zinc deficiency disease in deer?
Uneven geographical distribution of trace elements and substandard feeding management can both cause trace element deficiency diseases. Targeted and appropriate supplementation of the trace elements essential for deer is the most effective method for preventing and treating trace element deficiency diseases in deer. In the deer body, trace elements act as catalysts for various enzymes and as activity regulators of proteins, fats, polysaccharides, nucleic acids, vitamins, hormones and so on. Trace elements cannot be synthesized in the deer body and must be obtained from feed, while their excretion is continuous; therefore, according to

Prevention and Control Techniques for Selenium Deficiency in Chickens (Exudative Diathesis)
Selenium deficiency is one of the common trace element deficiencies in young chickens, and is more frequently seen in meat-type and dual-purpose chicks. It is mainly characterized by serous exudation in the loose subcutaneous areas of the chest, abdomen, thighs, submandibular region, and neck, which is why it is also called exudative diathesis. 1. Causes A lack of selenium in the feed is the main cause of this disease. The occurrence of this disease shows obvious breed differences; the incidence rate in fast-growing meat-type and dual-purpose breed chickens that develop quickly in early stages is much higher than in egg-type breed chickens. The most common age of onset is 14 to 70 days in young chickens, and it often occurs together with vitamin E deficiency, though there are also cases of it occurring alone.

How to prevent and treat selenium deficiency in raccoon dogs? Farmers need to master these methods
Selenium deficiency has obvious regional characteristics. Generally, a selenium-deficient geological environment causes selenium deficiency in humans and livestock, especially in years with abundant autumn rain, when selenium in the surface soil is lost with the rainwater, and herbivorous or omnivorous animals find it difficult to obtain enough selenium from plants, thus causing selenium deficiency. The narrow belt from Northeast to Southwest China is all selenium-deficient areas, with western Heilongjiang Province and Liangshan in Sichuan being the most deficient. In selenium-deficient animals, the selenium concentration in the organs and tissues of the body decreases. Under actual production conditions, liver necrosis may occur, or it may appear together with muscular dystrophy, mulberry heart, and white muscle disease. Clinically, various animals show different manifestations, but the common manifestations are decreased productivity, reduced number of offspring, infertility, movement disorders, and in mammals, retained placenta. When raising animals in selenium-deficient areas, attention should be paid to selenium supplementation.

How to prevent and treat selenium deficiency in raccoon dogs? Detailed methods and key points
Prevention and treatment of selenium deficiency in raccoon dogs. Selenium deficiency has obvious regional characteristics. Generally, a selenium-deficient geological environment causes selenium deficiency in humans and livestock, especially in years with heavy autumn rain, when selenium in the surface soil is lost with the rainwater, and herbivorous or omnivorous animals find it difficult to obtain enough selenium from plants, thus developing selenium deficiency. The narrow belt from northeast to southwest China is all selenium-deficient areas, with western Heilongjiang Province and Liangshan in Sichuan being the most deficient. In selenium-deficient animals, the selenium concentration in the organs and tissues of the body decreases, and in
