Water-essential nutrients for foxes
Water is an essential nutrient for foxes, and it is the main component of cell protoplast. In animals, water accounts for more than 2% of the total, 40% in the cell, 20% in the tissue, and 5% in the blood. The fox loses all fat and liver sugar, or even half the protein, and can barely survive, but if the body loses 10% of its water, it will die. The digestion, absorption and metabolism of various nutrients in fox feed are carried out in an environment with water. For example, saliva needed to digest feed,

Diagnosis and Prevention of Nutrition and Metabolic Diseases in Fox
Nutritional and metabolic diseases mean that the nutrients contained in feed, especially vitamins and minerals, can not meet the growth and development needs of foxes. Sometimes nutritional metabolic diseases occur not because of insufficient nutrients in feed, but because of digestive disorders in animals. In the preparation of feed, attention should also be paid to the interrelationship between vitamins and minerals (complementary or antagonistic). The following five kinds of nutritional and metabolic diseases are easy to occur in fur animals. (-) Vitamin A deficiency

How many snakes do you need to collect 1 gram of dried poison?
The detoxification of different species of venomous snakes varies greatly. Compared with the rate of dry poison, the average venom of king cobra, sea snake and silver ring snake is 101.9 mg, 2.5 mg and 5.0mg respectively. That is to say, the detoxification amount of the king cobra is 41 to 20 times that of the sea snake and 20 times that of the silver ring snake. Obviously, the king cobra has such a large amount of detoxification that it only takes about 10 to get 1 gram of its dry poison. However, to get 1 gram of dry venom from the sea snake, Bungarus bungarus, it takes 200 to 40.

The etiology, diagnosis, prevention and treatment of vulvitis and vaginitis in dogs
Vulvitis is inflammation of the vulva and vestibule. Infection is often caused by vulvar trauma during delivery, lax disinfection of hands or instruments during midwifery, and bacteria brought into the tail. During mating, vulvar mucosal injury can also cause the disease; vaginitis is vaginal inflammation. Primary vaginitis is more common in some large dogs before sexual maturity, such as German shepherds, boxers and so on. Secondary vaginitis is more common in adult dogs. It is induced by prolonged estrus, unclean mating, infection during childbirth, and secondary infections in the uterus, bladder, urethra and vestibule. Vaginitis is often complicated with vulvitis.

Is the project of extracting heparin sodium from pig small intestine feasible?
Heparin sodium is an important biochemical drug, which is used in clinical treatment of acute myocardial infarction and viral hepatitis. Combined with ribonucleic acid can increase the curative effect on hepatitis B. Combined with chemotherapy, it is helpful to prevent cancer cell metastasis. In addition, it also has the effect of preventing thrombosis. The production of heparin sodium is in short supply and there is a great gap in the international market. The intestinal mucosa of about 2000 pig small intestines after processing casings can produce 1 kg of heparin sodium, worth about 22000 yuan. Therefore, it is valuable to produce heparin sodium from the by-product of porcine small intestinal mucosa.
