Formosan research worker have made headline by genetically modifying a herd of 300 cattle to produce Milk River that is somewhat akin to human titty milk .
The scientists put in a human gene into the cows ' inherited information , and the beast ' mammary glands nowimbue their milk with large quantity of muramidase , a protein that is abundant in human Milk River , but not the bovid variety . Aside from give the modified cow milk the solid , sweet-smelling taste that you may or may not retrieve from your infancy , the introduction of muramidase makes the milk much healthier and more alimentary , fit in to Ning Li ofChina ’s Agricultural University in Beijing , who led the research .
Chinese researchers have made headlines by genetically modifying a herd of 300 cattle to produce milk that is somewhat akin to human breast milk.
To help ameliorate malnutrition among shaver , Li and his confrere desire to get the qualify Milk River through the testing phase and onto the Formosan market within three years .
But is the"transgenic " ( genetically modified)milk really sound ? And is it secure ?
Initial research suggests it is indeed safe and may provide significant wellness benefits , experts say . But much more examination must be done — and will be done — before you see homo / cow Milk River on the market in the United States .
well gut bacteria
" Human milk has 1,600 clock time more lysozyme than moo-cow and goat Milk River , " said Elizabeth Maga , an animal scientist at the University of California at Davis who , along with a team of investigator , conducts like inquiry to that of Li ’s chemical group . " This protein plays a big persona in putting a upright set of bacterium in the intestine . "
Human milk is , as you might have a bun in the oven , sound for humans . " There are a lot of studies that have shown that breast - give human babies are much good for you than ones that get convention , and one of the reasons seems to be that they have much better gut bacteria , which are right at protect against diarrhea , " Maga toldLife ’s Little Mysteries , a babe web site to LiveScience .
The UC Davis group has inclose the human cistron for lysozyme into goats so that they produce milk with 68 pct as much lysozyme as human milk . Because the modified Milk River is close than normal goat milk to what woman by nature produce and baby devour , it is very likely to be safe for human beings — but this has n’t been proven .

" We have n’t done any human trial yet , " Maga say . " By feeding the transgenic goat Milk River to baby pigs , which attend as a model for humans , we can see the encroachment of what the Milk River might do to humans . "
" What we ’ve depict is that our transgenic Milk River lead to a bull bowel that has a great Earth’s surface area , which allow for better absorption of nutrients , and which has more immune compounds present , " Maga added . Pigs with diarrhea also exhibited improved health when fed transgenic human / goat milk .
Human trials
If it has the same effects in humans , Maga said , the milk could someday help still malnourishment triggered by diarrhea , which is a lead cause of baby fatality rate in some developing land . The limited moo-cow Milk River would n’t be just for infant ; conceivably any malnourished person , or somebody miss ingut bacterium , could gain from drinking it .
But before that encounter , transgenic milk must move to the human examination stage . In the United States and Europe , genetically modified food gets a bad hip-hop , and so human trial will probably be much slower to bump here than in China .
" Any transgenic animal merchandise that goes on the market has to undergo extensive characterization beforehand . I ’m sure in China they have a program to do that just like they do here , " Maga said . But the departure is , China has a luck more resources and personnel do work on it , as well as a whole different attitude toward genetic modification ( GM ) , she explained . " In this country and in Europe there ’s a very loud anti - GM lobby , with advocates claim that GM is insecure . "
Keith Schneider , a intellectual nourishment scientist at the University of Florida who studies solid food safety , concurs . " With as much flack as we have in this commonwealth over GM , it will probably take much foresighted than three years to make it through [ the testing level ] to the market , " he said .
By contrast , Sky News in Beijing reported that a humans , Jiang Yao , recently taste the human / moo-cow transgenic milk , and had this to say about it : " It ’s good . It ’s good for you because it ’s genetically modified . "
Animal safety
To establish gene interpolation as a practicable method of dairy production , enquiry must also be done to prove the human Milk River transgene — the one being added to the cow and goats — does n’t have any unintended consequences or side effect . So far , no abnormalities have been found in the transgenic goats ' replica , in their resistant system or in the bacterium in their faeces . But there are many more affair to find out . As Maga noted , " It ’s very hard to prove a negative . "
