Breeder: Is it really true?
It is also known as furazolidone, which is mainly used to treat bacterial enteritis and coccidiosis in chickens. It has a moderate therapeutic effect and has been widely used in the treatment of chicken diseases in the past. On June 5, 2002, ç—¢ç‰¹çµ has been listed as a banned veterinary drug by the Ministry of Agriculture and is strictly prohibited from being used in any food animal. The main reasons are as follows:
First, the amount of treatment is not much different from the amount of poisoning. In the past, the therapeutic amount used in the treatment of avian enteritis and coccidiosis was generally 0.04%, and it was insoluble in water, so it could not be used for drinking water. The amount of poisoning is more than 0.06%, and the amount of treatment is very close to the amount of poisoning, so it is difficult to grasp in practical applications. The amount is small, the therapeutic effect is not achieved, and the large amount is easy to cause poisoning. For example, 300 ducks raised by Zhang, Wangdian, Fuyang City, Anhui Province, have been treated with ç—¢ ç—¢ ç—¢ , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , death. More than 100 people died on the second day. Because there was no specific drug detoxification, it caused great losses, which caused a great blow to the spirit of the farmers.
Second, long-term use of ç—¢Terling is easy to cause drug resistance, so that the drug loses its efficacy. Causes bleeding syndrome, which causes the chicken to lose weight, grow poorly, and eventually die. The use of laying hens can reduce the production of eggs. The use of sick chickens also increases the burden of liver and kidney, damages the liver and kidney, and aggravates the condition.
The third is the long-term use of 痢特çµ, which has residues in chicken liver, chicken, pig liver and pork, which has an impact on human health. Its residual drugs can damage the human hematopoietic system, causing hemolytic hyperemia, agranulocytosis, thrombocytopenia, and may also cause peripheral neuritis in humans, and there is no specific drug treatment.
In summary, the majority of farmers should raise awareness, in order to raise safety and personal health, please do not use 痢特çµ. For those who still use 痢特çµ, it is also recommended that it is better or not. In addition, the baby's immune system and liver have not yet developed, and the sensitivity to ç—¢ç‰¹çµ is particularly high. Therefore, ç—¢ç‰¹çµ has a greater potential threat to babies. The therapeutic bacillary dysentery can be replaced by norfloxacin, and the treatment of protozoal diseases can be replaced by metronidazole drugs.
A longpass (LP) Filter is an optical interference or coloured glass filter that attenuates shorter wavelengths and transmits (passes) longer wavelengths over the active range of the target spectrum (ultraviolet, visible, or infrared). Longpass filters, which can have a very sharp slope (referred to as edge filters), are described by the cut-on wavelength at 50 percent of peak transmission. In fluorescence microscopy, longpass filters are frequently utilized in dichroic mirrors and barrier (emission) filters. Use of the older term 'low pass' to describe longpass filters has become uncommon; filters are usually described in terms of wavelength rather than frequency, and a "low pass filter", without qualification, would be understood to be an electronic filter
