The scientists behind the development hope to create herds of low-lactose cows that would eventually produce new types of dairy products to be sold in shops in between five to ten years time. The researchers found the milk contained nearly four times as much omega-3 fatty acids compared to milk from an ordinary cow.
According to the lead researcher Professor Ning Li, this modified human milk is set to hit the dinner table within 10 years or so: “We aim to commercialize some research in this area in coming three years.
All rights Reserved. Science’s COVID-19 reporting is supported by the Pulitzer Center. Many dairy cows become sick each year with a disease called mastitis.Mastitis happens when bacteria gets inside the udders of the cow and cause an infection.
Recently, scientists have genetically modified dairy cattle to be hornless and to be resistant to certain diseases [6–8]. “The whole approach,” he says, “is based on sound science and on past experience going back more than a century.”. Critics of the technology have reacted angrily to the research and questioned the safety of milk from genetically modified animals. Hello antibiotic resistant microbes? Is gene therapy ready to treat some forms of autism?
That is to say, human beings have modified almost every domesticated foodstuff, plant, and animal through traditional breeding techniques. According to an ABC program: “It was a plan to genetically modify cattle and to change the dairy industry forever.”. We hope to commercialise it in the future.".
Genetically modified cows could fart less. Both the genetically modified babies and salmon, if unleashed to the public, can effectively change the very genetic structure of future generations — changes that can cause serious long-term consequences that we do not even fully understand. This human-cow hybrid milk is now being lined up as an alternative milk formula for babies, with scientists envisioning ‘herds of genetically modified cows’ to ultimately provide the human breast milk needed to feed newborns.

The latest recruits in the fight against COVID-19 are munching hay in a South Dakota barn. The question is how long will scientists continue to endanger public health and the welfare of all living creatures involved with rampant genetic modification of nature before the consequences present themselves in such a manner that invokes serious repercussions.
The cow antibodies were four times better than convalescent plasma at preventing the virus from entering cells, the company announced last week. Developing that treatment “gave us the initial knowledge to focus on the right target,” Sullivan says.
This human-cow hybrid milk is now being lined up as an alternative milk formula for babies, with scientists envisioning ‘herds of genetically modified cows’ to ultimately provide the human breast milk needed to feed newborns. So far, no antibodies generated by the animals have been approved for treating any disease. Dr Helen Wallace, director of Genewatch, added: "There is a question of food safety with GM livestock. As pandemic pounds U.S. universities, federal support helps their labs stay afloat, Top U.S. scientists left out of White House selection of COVID-19 vaccine short list, See all of our coverage of the coronavirus outbreak, Most companies trying to produce antibodies to combat COVID-19, the plasma is being tested in clinical trials as a treatment for the virus, were four times better than convalescent plasma, Early approval of a COVID-19 vaccine could stymie the hunt for better ones, Millions of animals may be missing from scientific studies.
GENETICALLY modifying cows so they burp and fart less - that's one of 40 initiatives to reduce emissions being considered by the cattle …
BGH is a normal growth hormone found in cows; rBGH is a slightly altered version that’s produced by genetically engineered bacteria.
It also contained half the amount of unhealthy omega-6 unsaturated fat, which have been linked to cancer and heart disease.
Cows make good antibody factories, and not just because they have more blood than smaller animals engineered to synthesize human versions of the proteins. The benefit of using the genetically engineered cows is that they are able to produce human antibodies in much higher quantities than people can. Instead of making just one antibody variety, the cows fashion polyclonal antibodies, a range of the molecules that recognize several parts of the virus.
In a separate study, published in the journal of Transgenic Research, another group of scientists at the Inner Mongolia University have created a genetically modified cow that has high levels of omega-3 fatty acids in its milk.
Five calves were born in April this year and three were found to carry the genes needed to create low-lactose milk, although two of them died within 24 hours of birth. The research has, however, raised concerns from animal rights campaign groups and critics of GM technology. “This is promising,” says Amesh Adalja, an infectious disease physician at the Johns Hopkins University Center for Health Security. For the “human-like milk”, 10 years or maybe more time will be required to finally pour this enhanced milk into the consumer’s cup.”. She said: “Offspring of cloned animals often suffer health and welfare problems, so this would be a grave concern.”.
Hello genetically modified milk?
Their blood can also contain twice as many antibodies per milliliter as human blood, says Eddie Sullivan, SAb Biotherapeutics’s president and CEO.
This diversity may make the cow’s proteins more powerful than monoclonal antibodies, he says, and they may remain effective even if a virus mutates. Dr Li explained that mammals do not naturally have the ability to make omega 3 fatty acids nor convert the less healthy omega 6 unsaturated fat into healthier forms. Before the animals start to release these antibodies into their blood, the cows need a starter immunization—a DNA vaccine based on a portion of the virus’ genome that preps their immune system. “We want to have as many countermeasures as we can.”. No one eats genetically modified animals.
Infectious disease physician Manish Sagar of Boston University Medical Center says he will remain skeptical “until I see further proof that production of antibodies in cows is a lot more feasible and economically viable” than other methods. Pushed by the USDA and major biotech corporations, AquAdvantage salmon (the modified brand), was just moments away from approval when Congress blocked the FDA from approving the salmon for consumption due to serious health and environmental concerns. When rBGH is given to cows, the animals’ milk production increases by 10 to 15 percent.
When the COVID-19 pandemic erupted, SAb Biotherapeutics had already completed a clinical trial with cow-generated antibodies against Middle East respiratory syndrome, which is caused by a coronavirus related to SARS-CoV-2. Then comes the injection that contains a piece of SARS-CoV-2’s spike protein, which serves as the virus’ passkey to cells. Most companies trying to produce antibodies to combat COVID-19 have pinned their hopes on mass-producing identical copies of a single version, a so-called monoclonal antibody that homes in on and attaches tightly to a particular section of a virus. We are attempting to breed a dairy cow that produce low lactose milk for supplying the market.
