If cattle are not given B 12 supplements then they are given cobalt supplements
I see you're finally backing away from your contention that all cattle are given B12 suppliments. It took you long enough. But it's progress that shows that you are actually capable of learning. You're just a very slow learner. And your inability to quickly admit it to yourself when you are clearly wrong (which is due to your fragile ego) contributes to your learning disability.
However, even though you are correct to back off your original contention that "all cattle are given B12 suppliments", your modified contention that if they are not given B12 then they are given cobalt, is still false.
Some cows get neither B12 supplements nor cobalt supplements.
Again your own source contradicts your contention.
Cobalt. Cobalt is needed only for the ruminal synthesis of vitamin B12. Cobalt requirements are higher when cattle are fed high-grain diets, because more B12 is required to metabolize the end products of rumen fermentation. Cobalt may be very deficient in some soils, so including it in trace mineral supplements is a sound practice.
Cobalt supplementation is only required if the soil in which their feed is grown is deficient in bioavailable cobalt.
What you seem to have trouble comprehending is that just because supplements are available, that does not mean that all cattle are given those supplements.
The cattle industry runs on razor thin profit margins so they do not just willy-nilly spend money on supplements they don't need.
This salt lick costs $6.49 at Tractor Supply
And this salt lick with cobalt & iodine costs $9.49
The cobalt salt lick costs a whopping 46% more than the plain salt lick.
It would make no fiscal sense to spend the extra $3 on a cobalt salt lick unless your animals need it.
