"White nose" disease had not been heard before. You go home to find books or go online to find information. There is no such thing as "white nose disease." However, after listening to my explanation, you will find some of the symptoms of “white nose disease†when you go home and look for your current books. "White nose disease" is the most typical in the northeast since 2001. At the beginning, the folks in the northeast discovered the heads of their own foxes, otters and scorpions. The red spots slowly appeared from the black, and then the area gradually expanded. Then the white spots appeared. Finally, the nose was one by one. All turned white. Then it was also found that the paws gradually became longer and whiter; the footpads also turned white and thickened. Began to think, nose, head, paws, white mats turn white, it does not affect the sale of skin anyway. However, it was later discovered that the animals whose heads, claws, and white mats turned white gradually became narrower and smaller. Some forelimbs on the forefoot gradually lost hair and dander, and it was difficult to support the body. Use, found that the survival rate of offspring is very low, and the production performance is poor. As a result, "white nose disease" gradually spread. "White nose disease" is only a minor name. Due to the short time of discovery, we are still under constant research. The real "name" of the disease has not yet been determined. Therefore, I have to follow the name "white nose". 1, reason: After this disease, we did not know what the disease was at that time. Treating it as a bacterial disease did not work well. Treating it as a parasitic disease did not work well. Finally, we combined the use of feed in the actual production, from the perspective of nutrition to think of ways to treat, and achieved good results. Therefore, we tentatively determined that this disease is caused by the long-term imbalance in the feed we feed on fur animals. According to this line of thought, the long-term observation of efficacy from the end of 2001 to 2003 shows that the effect is very good. This also verifies that our judgment is correct. The disease has now been established and formal research procedures have been initiated. I believe that in the near future, the truth of the matter will soon surface. Through actual experience in production, it is still necessary to solve the current problems in production from the perspective of nutritional balance. So far, studies have found that “white nose†disease is actually a comprehensive disease caused by imbalanced nutrition metabolism, mainly due to lack of vitamins and minerals in production, lack of amino acids, or proportionate Caused by imbalance. 2, clinical manifestations: In production, the "white nose" disease has the following several manifestations: A. The nose is white: the nose appears black or brown gradually red spots - red spots - white spots - white spots; B. White mats, thickening, cracking, pain, and individual ulcers; C. Long and pale paws: Some are very long in individual paws, some of them are white in one paw, and some are all white in all paws; D. There is also a very special performance - dry claws, and some villagers called "dry claw disease." Dry claws, no meat; dark in color, dark red or dark red; produce a large amount of dander, continuous shedding; erect difficulty. The performance of "white nose" disease in reproduction is: A. Missing due to a large proportion of estrus is not obvious: especially the fox and the raccoon, estrus once a year. During the estrus, we have not seen the obvious symptoms of estrus until after the estrus period. Obviously estrus. Leakage due to this situation, and the proportion of this situation is large. B. Embryos are absorbed, calcified: matched with species, and the mother’s belly is also seen growing day by day. However, after a period of time, it was discovered that the stomach did not go to the chief, but gradually reduced, and finally, the embryos were absorbed and calcified. C. Large percentage of abortions and stillbirths: There are many causes of abortions and stillbirths. White nose disease can also cause a large proportion of abortions and stillbirths. D. abnormal calving: the baby's red, white, white, pink, white powder, but from the two or three days after birth began to gradually death, generally to postpartum more than 20 days on the gradual death of all. Even the very few who survived were individuals who were small and emaciated. This year, if we encounter this situation again, we should handle it early. In the production of "white nose" disease, there is a very special performance. There are no symptoms in front of it, and the initial growth is also very good. When it grows to a certain degree (usually during the growth phase of winter hair at the late stage of growth and development). Before), it does not go to the chief of the department, but to the young chief, that is, to the situation of growth. In Furukawa, a folk told me that the nephew of his family was 23 pounds. When I went there was only 3 pounds. In Jiang Gezhuang, in November, I also saw a large number of dumplings that were only about 7 or 8 pounds in size. Some farmers asked me: "Why didn't we have some feed before, but we don't have white nose disease. Now that we have a better feed, do we still have this kind of disease?" The reason is this. The quality of the feed we are talking about is only for the protein in the feed, and the amount of other multivitamins, minerals, and amino acids does not increase with the increase in the amount of protein. The more eggs and fishmeal are added, the better you think the feed is. On the contrary, the less eggs and fishmeal are added, the worse the feed is. When the amount of protein in the feed is low, the proportion of various nutrients is also appropriate. Now, due to the increase in the supply of protein, this relative balance is even more destroyed, as I said earlier. To the same proportion of calcium and phosphorus, originally calcium is high, and calcium is still added, so the reason for making up more is the same. Some farmers also asked me, "My family's fur animals suffered from white nose disease last year. I didn't care about it. It was just the winter. However, after the baby was born, what happened?" This situation has the following reasons: 1) In the winter, the feed supplied to fur animals was poor, and the level of protein in the feed was reduced. The proportion of various nutrients in the feed was also relatively improved. 2) In winter, the feed intake of fur animals gradually decreases, and the proportion of various nutrients that can be used in the body is also relatively improved. 3) In the winter, the incidence of various diseases is relatively reduced. Therefore, the amount of various drugs added to the feed is relatively reduced. All foods eaten by the animals into the digestive tract, except that water and glucose can be directly absorbed by the intestinal tract and directly used by the body, any other substances are first eaten by microorganisms in the digestive tract, and in their metabolites, they contain Rich in vitamins, minerals, amino acids and enzyme preparations, as well as the types and quantities of growth factors, can meet the normal growth needs of animals. However, the frequent use of a large number of drugs, on the one hand, prevents diseases and on the other hand also destroys these microorganisms in the digestive tract. As a result, the types and amounts of vitamins, minerals, amino acids and enzyme preparations and growth factors produced are greatly reduced. In the winter, when the amount of drugs in the feed was reduced, the microorganisms in the intestine were restored, so it was getting better in the winter. However, after the breeding season, a large amount of micronutrients supply the fetus's growth needs. Therefore, the lack of maternity further manifests itself. 3, preventive measures: Through practical experience, “white nose†disease can be effectively prevented and treated after supplementing a wide variety of vitamins, minerals, and amino acids with balanced proportions. However, this is a chronic disease that cannot be treated like a cold. Take medicine today and tomorrow will be fine. But it needs gradual conditioning and it will take some time.
