1 How to determine
Animal feed poisoning?
Feed poisoning has a large population, and the incidence of large feed intake is high and the symptoms are obvious. Normally, the incidence of veterinary animals is higher than that of old animals; the incidence of beasts is higher than that of mother animals; the symptoms of early feeding are earlier than those of feeding animals and are often accompanied by hyperactive neurological hyperactivity, vomiting, paralysis, increased salivation, and diarrhea. .
2 What happened to salt poisoning? How to rescue?
When fish fed with fishmeal, salty fish, bacon, or salt-immersed fresh fish is used, the salt content of the mixed feed will reach 2% to 4% without fully immersing the water in advance and changing the water several times. After eating such feed, quail and otters will immediately cause poisoning. In addition, calculation errors or uneven seasoning and insufficient drinking water can all lead to salt poisoning. The feed amount of salt for fur animals is 0.5 to 1.0 g per kilogram of body weight per day, and the amount of 1 to 1.2 g per kilogram of body weight per day for lactating mother animals is appropriate.
In the case of salt poisoning, those who have mild symptoms can be relieved by sufficient drinking water. Excessively increased excitatory intravenous injection of 25% mannitol lowered intracranial pressure and sedation with chlorpromazine.
3 What are the diseases that can cause fur animals?
Animal feeds, especially spoilage fish, are often contaminated with Clostridium welchii, and can cause enterotoxemia in fur animals; fat oxidation occurs in fish that has been stored for a long time and long-term feeding can cause yellow fat in fur animals; cattle, sheep, Pork and poultry meats and canned or spoiled cans can cause Salmonella and Clostridium botulinum infections in fur animals, sometimes Escherichia coli infection and acute bacillary dysentery; long-term feeding of mild cornmeal, wheat bran and peanut cake Can cause mold poisoning in fur animals. How did yellow animal fat happen? How to prevent? Yellow animal fat in fur animals is mainly caused by prolonged feeding of deteriorated animal feeds, especially fish that have been stored for a long time. The fat contained in fish is unsaturated fatty acids, which can easily be oxidized and produce some harmful substances when stored for a long time or when the storage temperature is too high. If the animals are fed continuously for a period of time, yellow fat can occur and die.
Supplementation with VE and choline chloride in feed can prevent the occurrence of the disease. Especially for long-term feeding of fish that has been stored for a long time or that has been oxidized and deteriorated, VE and choline chloride should be supplemented in large doses. If yellow furosis has already been diagnosed in fur animals, degenerate fish and meat should be immediately stopped and replaced with fresh animal feed. At the same time, VE should be injected into sick animals at a dose of 10 mg per kilogram of body weight and 25 to 50 mg per dose of VB1. If there is inflammation in the digestive system, gentamicin, norfloxacin, etc. can be used to control enteritis. What are the characteristic pathological changes in yellow animal fat in fur animals?
When the animal died of yellow fat, the necropsy showed yellowing of the subcutaneous fat, especially in the back and muzzle. Liver volume increased significantly, texture rough and brittle, yellow or grayish yellow; gallbladder highly filling, full of viscous dark green bile. The kidney is swollen and the color is grayish yellow; the mesentery, omentum and renal adipose sac are yellow.
