No disrespect intended, but you are out of your depth and seemingly don't realize it. You should not be nearly this confident. Instead of googling, "vegans need b12", you should have googled: "cows b12 injection" and come up with some of these hits:

https://morningchores.com/b12-for-livestock/

https://www.drugs.com/vet/vitamin-b-12-1000-mcg-injection.html

https://au.virbac.com/products/sheep-cattle-nutrition/hy-b12-vitamin

https://nz.virbac.com/products/trace-elements/smartshot-b12

https://farmanimal.elanco.com/au/sheep/product-directory/cobalife-vb12

While this 20 seconds of research does not establish that supplementing B12 is actually necessary for livestock, it does go towards establishing that it is an industry-wide practice.

Yeah I probably should have, thanks for those links.

The existence of products designed to inject B12 is different to what I interpreted the person who I replied to was saying though.

I understood them as saying that farms are injecting B12 into animals so that meat gains some kind of nutrient that isn’t naturally occurring or not occurring at an appreciable level.

I have no doubt animals have all kinds of vitamin deficiencies and receive supplements to improve the over all health of the animal and the nutritional value of meat.

But is this the reason they are injecting B12?

Obviously I’ll read more on it.

EDIT: so the very first link basically confirmed what I just said, when an animal is deficient in B12 farmers inject it to make it more healthy. They aren’t injecting B12 into animals because animals just don’t have B12…

You also don't address the fact that carnists have poorer B12 levels than vegans. I am willing to bet that the only time you ever care or think about B12 is when you want to argue against ethical veganism. Have you ever had your B12 serum level checked? Have you ever tried to calculate your required daily intake or your actual daily intake? Obviously not. This is a disingenuous argument right from the beginning. You are working backwards from the conclusion you wish to reach and using any rationalization you can lay your hands on.

It is obvious you don't actually know what you are talking about, which is darkly ironic considering your accusations. You are arguing for what you want to be true, but you have been careful to keep yourself ignorant of what IS true, because if you knew then you might have to change.

To be fair, capital and social forces have conspired to help you remain ignorant.

Yeah, when you link a source for your claim that people are injecting B12 into animals I’ll reengage with you.

I tried googling and got nothing.
