In the feeding of fur animals (water fleas, foxes, scorpions, etc.), some farmers have not provided feed according to their nutritional needs in order to reduce feed costs. When processing feed, they do not understand the scientific ratio, the processing methods are improper, and the nutrition is destroyed. Ingredients cannot achieve ideal production goals.
The feeds needed for fur animals mainly include meat dumplings, grains, fruits and vegetables, trace elements, etc. When these feeds are processed, if they are not balanced, nutrition is not comprehensive, and methods are not properly used, feeding of deteriorated feeds will cause fur and beasts to suffer. Nutritional deficiency or accidental poisoning. Now we introduce relevant knowledge for reference on the above issues.
First, the protein in the feed should be sufficient
In order to reduce expenditures and reduce the supply of meat and poultry feed, some farmers use cereal protein as an alternative to animal protein, resulting in abnormal estrus in male and female animals, difficulty in mating and breeding, and more mothers and animals, which are prone to abortions and embryo absorption even if they are produced. Under the Aberdeen Beast, due to a small amount of milk, Aberdeen does not suck enough milk, body size is thin, growth is slow, resulting in stiff, small size when playing, skin size is short, poor quality plush, with hooked hair, leather price Very low. From November to May of the next year, mink meat protein needs about 20 grams, about 8 grams of plant protein, about 16 grams of meat protein from June to October, about 9 grams of plant protein, and the fox and cockroach should also be based on Need to provide enough protein, excessive supply of protein, animals can not absorb, will cause waste.
Second, the role of fat in the feed content
Fat content in the feed is low, there will be fat-soluble vitamin deficiency, no milk during lactation, impaired growth of young animals, weight loss, plush rough, dull luster, reduce the quality of fur, susceptible to respiratory diseases. Every day, minks need only supply 5-8 grams, and the supply cannot be excessive. Especially in the breeding season, too much will affect the absorption of other nutrients and reduce the reproduction rate. During the growth stage of cubs, lots of feeds containing fat are fed in large amounts. The cubs are prone to body fat and are not well developed. They can feed more fat before playing hides, which is good for the growth of plush.
Third, the grain feed content should be suitable
Mainly include corn, sorghum, soybean meal, wheat bran, and fruit and vegetable feed. At present, there are many fur animal farms feeding large amounts of cereals, because foxes, crickets, and centipedes are carnivorous and semi-predatory animals. Starch and carbohydrate digestive enzymes are relatively low. Feeding too much cereal feed, lacking long-term meat feed supply, and lack of animal protein can seriously affect the normal growth, development and fur quality of foxes, cockroaches, and cockroaches. In the process, the physique is thin, the disease resistance is poor, and it is easy to suffer casualties. Cereal feed in each feeding phase, the amount of feed should be increased or decreased. Because grain feed is involved in fat metabolism and amino acid synthesis, it has the effect of storing and saving protein, and it contains cellulose to make feed loose, increase palatability, stimulate gastrointestinal motility and secretion of gastric juice, and promote digestion and absorption of feed. Insufficient supply of cereal feed, but also easy to cause inflammation of the urethra, suffering from urine disease, digestive dysfunction, leeches feed, generally grasp every day 20 to 25 grams, fox, raccoon can be fed more properly.
Fourth, lack of minerals and trace elements will cause the following symptoms in the herd
If the diet lacks calcium and phosphorus, the growth of the beasts is slow, and the bones are softened, calcium and phosphorus additives such as bone powder, bone chips, and cod liver oil should be promptly and reasonably supplemented to prevent and treat the disease; zinc deficiency will reduce the quality of the skin; Copper will experience a decline in the quality of fleece; lack of selenium will cause white muscle disease; cobalt is mainly in the form of vitamin B12, a necessary condition for the production of hemoglobin and erythrocytes, especially in the diet of leech 0.5 mg of cobalt chloride or cobalt nitrate. /Kg body weight has a good effect on improving the survival rate of leeches and reducing the risk of empty and puppies; the lack of salt in feed, the loss of appetite in the herds, the slow growth of the beasts, the apathetic mood, urine, and urine Each day is generally 0.3 to 0.8 grams, too much will cause salt poisoning.
Fifth, the amount of vitamins added
貂 Daily dose of 500 to 600 international units of vitamin A should be supplied per kilogram of body weight. If it is lacking, when the baby is born from 1 to 3 months of age, body twitching occurs, head retreats, and activity is disordered. It is very sensitive to external stimuli, often In the cages, the animals constantly circulate, and at the same time, the cubs were accompanied by diarrhea and pneumonia. The growth and development were not good, and they also showed bad symptoms such as delayed tooth replacement.
Vitamin C deficiency animals susceptible to red melon disease, if not treated in time, the mortality rate of up to 80% or more, most of the deaths in the 5 days of age, in the mother's pregnancy, late, to feed fresh green leafy vegetables and Vitamin C tablets can prevent red paw disease in cubs. Each beast can be given a drop of glucose and vitamin C solution. The diseased beast can be fed twice a day, and the mother beast can be given a vitamin C supplement. When selecting the species, we must eliminate the beasts suffering from red claw disease.
In the absence of vitamin E, it will seriously affect the reproduction rate of breeding animals, and may also cause adipose tissue inflammation (yellow steatosis, hepatic and renal steatosis). During the breeding period from January to May, appropriate feeds containing vitamin E, such as wheat buds, will be properly fed. , cottonseed oil, fresh liver, beef, egg yolk, lettuce dishes. The amount of vitamin E is directly proportional to the amount of fat in the feed. In the summer, fish (dried fish) as the main feed, pay attention to add vitamin E tablets to prevent yellow fat, 2 to 3 times per week, each half , The wolfberry fruit is 5 milligrams per kilogram body weight, the treatment dosage is 15 milligrams, the vitamin E deficiency sometimes causes because of the lack of selenium, should find out the reason, promptly remedies.
When purchasing fur animal feed, it is necessary to carefully check the variety and content of nutrients in the feed. In recent years, there have been many manufacturers of special feed, and some manufacturers' products are not fully priced, which has caused problems in the animal herd and has been seriously damaged.
