Wow. We are so fucked.
Vaccinating cows so they create milk with antibodies. Supposedly.
In Uzbekistan, a variant of milk was recently introduced on the market that, according to the manufacturer, has the ability to strengthen the immune system, a product that claims to be able to neutralize the coronavirus.

I skimmed the article, did not read the details, but the idea does seem to be as you described it.
My initial reaction is that it is snake oil. The reason is that antibodies are generally molecules that are too big to be absorbed across the gut lining. In many animals, this is the reason it is SO important for newborns to receive colostrum. Some species like cattle and horses receive virtually all of their maternal antibodies through the colostrum (first milk produced at birth that is very rich in antibodies - it is darker and thicker than normal milk). For a period of 12-24 hours, the newborn gut remains "open", allowing the larger antibody molecules to be absorbed through the lining and into the bloodstream. After 24 hrs, the newborn experiences "gut closure" and can no longer absorb the antibodies (the lining will no longer allow large molecules to cross over into the bloodstream), so if they don't receive the colostrum by then, administering it will be of no use and they will face a very difficult time surviving because of seriously reduced immunity. Humans and dogs, for example, receive a lot more of their maternal antibodies through the placenta. Receiving colostrum in puppies is still very helpful, but not as life-or-death important as it is in calves and foals. Gut closure is important in all species to keep disease-causing pathogens from constantly being absorbed into the bloodstream through the gut. So, 24 hrs is about the limit for the maternal antibodies in colostrum to be absorbed, then the newborn gut closes to protect against pathogens.
The above paragraph applies to IgG (systemic) antibodies. There are also two other types, IgE and IgM. Of interest as it pertains to this article are the IgM antibodies. They aren't systemic "in the bloodstream". They exist on lining-surfaces within the body (respiratory and gut linings, for example). They are helpful at neutralizing pathogens at the point-of-entry, before they ever get into the system for the IgG antibodies to fight. These antibodies are the type that are produced in response to oral and nasal vaccines, whereas injected vaccines are aimed at producing IgG antibodies. They do not get absorbed into the system, they are formed and remain on the lining surfaces in response to exposure at these locations. However, to stimulate their production, we administer an oral or nasal vaccine that is an analog or modification of the pathogen itself. The vaccine is not "antibodies", but the article claims they have antibodies in their engineered milk, not analog/modified pathogens.
I'm not an immunologist, and my training in the field was circa 1990. A lot may have changed in the ability to modify and engineer synthetic antibodies in the research field since then, but I'm still not aware of any "antibodies" administered orally being able to be absorbed across the gut after it has closed. Maybe that was addressed somewhere in the article and I missed it in my quick scan. Again, I'm not in the research field and a lot may have changed. so take that into account.
