Ethanol of quinoline: Cultivate contrabands and add another one
Author: The intersection of arm spread and North Korea Lao JinHua Zeng Jin
March 29, report of CCTV " Weekly Quality Report ", Jiangsu Province the intersection of Lianyun Harbour and city remit the feed of carp which agricultural biological Science Technologies Co., Ltd. produces and contains the violated medicine " Ethanol of quinoline " ,Lead to the fact the locality cultivates carps and dies in a large amount. It is said, the enforcer has collected the sample of feed of carp of 11 batches that this enterprise produces to measure, the result shows, 11 batches have added ethanol of quinoline, the supreme content reaches 244ppm; Meanwhile, in carp's body, finds the content of ethanol of quinoline is 4.6ppb.
At present, the enforcer has already closed down this enterprise, and place on file and investigate and prosecute.
Because quinoline ethanol have intermediate to accumulating toxicity obviously, have on most animals obviously cause lopsided function, there are three potential causings on also people, namely cause the deformity, cause sudden change, carcinogenic. So quinoline ethanol is all forbidden in U.S.A. and European Union as additive of feed. " Chinese beast's pharmacopoeia " (2005 edition) Also stipulate clearly, ethanol of quinoline is forbidden being used in poultry and aquaculture.
Will it be that one that is being traced is sneaking the rule to cultivate the trade with ethanol of quinoline? The rural newspaper reporter in the South understands some in the trade.
Urge additive of growth " Good and cheap "
Ethanol of quinoline is also called time and bred the promise, bred fairy quickly, belong to the quinoline. Why is it added to feed? Because quinoline ethanol urges to grow on function obviously.
Have research report claim in carp, Luo being fish, grass carp, spot fork tail add a certain amount of quinoline ethanol in the grain day in Hui, its growth rate can be raised by about 50%, but should control the dosage, otherwise the fish are poisoned dangers. Add ethanol of quinoline in aquatic products animal's feed, main function lies in raising the feed conversion ratio, but it accumulates the toxic characteristic, makes it accumulate in fish's body while becoming certain, will cause destroying to the liver, kidney of the fish greatly, the fish are when being stimulated, but a large amount of easy bleeding are dead. So, the goods fish that ethanol of quinoline is poisoned are apt to cause the death at various degrees in the course of transporting. It is reported, ethanol of quinoline can endanger various fish of each age, become particularly fish's morbidity, mortality are high with the carp.
Also it is reported, feed the meat chicken with the feed containing ethanol 25ppm of quinoline, Japan can improve to increase weight by 5%-10%, save about 6% of feed, stage of fattening shortens 3-5 days on average; Raise the grain, feed the laying hen with the intersection of 25-30ppm and density, the laying rate is raised by 5%-8.5% on average, the feed utilization ratio is raised by 2%-8%, Sichuan Province feed Company raises and tests the report, adds quinoline ethanol of 25ppm in the feed, laying rate raise 15.94%, material egg than 3.33:1, reduce by 1.77%; The duck has obtained and increased weight fast (increase weight to improve by 6%-13% on day) too by the quinoline ethanol test of 25ppm ,The remuneration of feed is high, reduce the feeding cost (save the feed 6%) Result.
Meanwhile, the cheap price of ethanol of quinoline is the important reason attracting feed enterprises to use too. One feed enterprise's formulator manager Wu in Zhejiang introduces to the rural newspaper reporter in the South, ethanol of quinoline is one kind " Good and cheap " Urge to grow additive,at present price is 40-45 yuan kilogram. Because the growth performance of various fresh-water fishes is different, the addition level in per ton of fish's feed of quinoline ethanol is lain between in 100-150 grams, among them the addition level of the feed of fish of carp's family is generally 80ppm, can reduce the bait coefficient 0.2 after using. "Convert with 3300-3500 the intersection of fish and material of ton, one cultivate cycle each fish, can save 0.3rd cost. "
Manager Wu says at the same time, because quinoline ethanol is allowed to use on the piglet, and the source is extensive, can also see ethanol of quinoline in many beast pharmacies or feed shops by mixing forms such as pharmaceuticals,etc. in sale in advance at present, it is very convenient to buy.
Known as for a time " The aquatic products clenobuterol hydrochloride "
In fact, the use in the feeding of ethanol of quinoline, the Ministry of Agriculture makes strict regulation in the announcement No. 168 in 2001: Can only be used in the pig whose weight is lower than 35 kilograms, addition level is 50ppm feed, forbids being used in poultry and aquaculture.
But so look like and gather together the agricultural company, the phenomenon of adding ethanol of quinoline in the feed is not a individual case. The official data are, in 2008, the feed that the Ministry of Agriculture launches in the whole country will add the violated medicine specially while monitoring the action, find that adds ethanol of quinoline and reaches 37 batches in fish's feed and birds' feed in violation of rules and regulations: In feed of 18 batches of detection in the first half of the year, 17 batches are chiken's and duck's feed, 1 batch breed fish mixed feed for pond; 19 batch of quinoline ethanol of detection in birds' feed of batch 1168 and aquatic products feed of the second half year, detection rate is 1.63%, higher than the detection rate of other violated medicines, the out-of-range " still relatively serious " of problem which uses ethanol of quinoline . In addition, it is 1.85% that three in the feed of albumen gathers the detection rate of cyanogen amine, the detection rate of furan thiazole ketone is 0.24% in pig feed of young animal and aquatic products feed.
