Hormone stimulates the secretion of milk: Make the craft and leave a question open
The past ten years such as trade such as dairy products hypernormal to develop at a high speed, break the intersection of cow and feeding and natural equilibrium between the dairy products processing industry - -Secrete the milk more in order to pursue cows, so that " hormone stimulates the secretion of milk " Exist in a large amount. Many milk industry experts infer tentatively, ethylene female phenol (D E S) Wait for hormone not to get rid of and cultivate links to enter ox's body in the cow, cause estrogen (fat material) with a certain amount of original milk ,And transmit to downstream dairy products products such as milk power, liquid milk,etc.. This doubts meaning milk power that it will not probably be a individual case to cause babies to be early-maturing. Why will the cow take in D E S? How did this estrogen enter milk power? Will the milk power of hormone become next to gather cyanogen amine three times? Taking a series of question, reporters have launched the further investigation. Make craft to be to the accomplice national dairy products senior engineer of research center Dr. Li Tao and tell " the first finance and economics daily " reporter, kind of source sex hormone is numerous,among them and incident most relevant hormone is for D E S. "This kind of hormone belongs to and kisses sex hormone of lipoprotein, can totally formate in organs such as gonad and renal gland cortex of dairy cattle's organism,etc., and enter in milk with milk, cholesterol, butterfat fat. " Li Tao introduces, making crafts of the milk power of our country adopt multistage high-pressure spray technology more at present, this technology has created the condition for the circulation of strengthening estrogen. It is introduced, pass the high temperature and deal with (spray drily) And then sulfhydryl- will include base molybdenum compound,it is oxidize it produces that molybdenum is sour to reduction reaction not to will happen, create conditions for the receptor is combined. In fact, estrogen combines hormone on the inner receptor of afterbirth, after it combines with the receptor, can make the conformation of the receptor albumen change, form the sexual organ and advance development finally. Li Tao points out, unsaturated fatty acid in baby's milk power is in a situation that there is no nitrogen to protect, the crossing the oxidizing value and increasing of milk power will cause the estrogen circulation to be strengthened too, and then change the conformation of the receptor albumen, cause the sexual precosity. Li Tao is thought whether utilizing fluorogenic analytic approach and infrared spectrum law contains D E S or other estrogen when can measure the milk power. On the 8th, Deng HaiHua, press spokesman of Ministry of Public Health, says, Ministry of Public Health has already paid close attention to the milk power to doubt that causes baby girl's sexual precosity report. But still there is not authority that measure the department and announce the relevant sampling inspection report at present. Develop sequela over the speed limit? The Chinese milk industry Wang HuaiBao, advisor of association, refers to when being interviewed by staff reporter before this, it is developed at a high speed that the milk industry of our country has been hypernormal in the past ten years, unprecedented in the world, "increase about 30 every year, the Inner Mongol reaches 40 especially. Start from 12 ten thousand cows, 20 ten thousand tons of milk in 1949, the scale of 1300 ten thousand cows that had already developed until today, 3650 ten thousand tons of milk, it exceeds 100 times to increase. " Behind what the output is increased severely, but the out-of-balance milk source value chain. Burn famous economist, Chinese Academy of Social Sciences industrial economy former the intersection of chief and Lu Zheng Professor points out, the original milk 80 of our country comes from the private investor, the milk source is dispersed, small, standardized and deficient, mismatch very much of processing industry of dairy products with high intensification. And " company and peasants or company + milk station + peasant household " The order mode causes the interests relation of every ring of industry chain of milk industry of our country to isolate each other again. National student drinking milk plan JianPing Jiang, director of Committee of Experts, say of our country the intersection of milk industry and agriculture, worker, trader at the value chain ratio of interests 1 : 3 : 6 . "Most cows raise the family to consider out of lowering costs, has already transferred to and fed and formated the feed, induce oestrus plainly, the ovary is plain,etc. hormone is often used for hastening parturition too. " Chinese milk industry reputable the intersection of expert and the intersection of man and cotton Wang reveal one the intersection of cow and one day most prolific the intersection of milk and 20 before the 10 year, under stimulating the secretion of milk the feed or situation that the medicine assists now, a cow can reach nearly one hundred kilograms to produce the milk in one day. Or involve and import the milk source Would once " gather cyanogen amine three times " in 2008 The intersection of incident and holy yuans of world of protagonist one of, measure different 3 of content, gather cyanogen amine in holy yuans of excellent clever 8 products of batch its, its source of milk comes from our domestic Mongolia and Hebei. Nine claim, " gather cyanogen amine 3 times " according to holy yuans of international the intersection of press spokesman and Cong Zhang After the incident, the companies all use instead and import the milk source, " the majority is imported from New Zealand " . If holy yuans of the intersection of respect and true of situation meant, mean falling into " hormone door " The original milk range of the disturbance will be thereupon expanded. The intersection of man and cotton Wang introduce, cultivate at the mode in cow, really there are two kinds of shapes in the world. "U.S.A. adopts and houses, and according to this country's relevant regulation, allow in the course of cultivating, use hormone in certain cases; The country of New Zealand cultivates cows, will inject hormone too during the course of beeding breeding; European Union does not allow to use hormone, and adopt and put the mode in a suitable place to breed. " The intersection of man and cotton Wang claim our country adopt, house while being American too at the intersection of culture and mode of cow, so will use hormone. He points out, in the developed country, remains etc. hormone in the finished product of milk power at the same time, there are strict regulations. Our country does not have a relevant regulation to residue amount in the milk power of hormone at present, also there is no relevant research.
