I'm confused as to how this would be ambiguous. If an animal is born in captivity it will probably be killed for meat at some point, that's just math...

I am pretty sure they're just saying that after 6 months they aren't suckling anyway and are grassfed through being a yearling until they're adults. Few farms will talk about killing their animals, of course, keeping what is happening sterile in appearance is pretty important for keeping the amount people eat high.

I hope none of that is controversial, it can always be assumed that animals born on a farm ultimately are eaten as meat... I'm a vegetarian and I'm not thrilled about it, but that's just math =/
