I'd have guessed the biometrics and location information was the most useful part.

But as others have pointed out these are primarily for dairy cows, which is pretty different from raising beef cattle (which is what I did).

There is a need to twice daily gather the cows to have them milked. And the pasture rotation is much more of an involved process than what we needed to deal with. We just plopped a gaint bale of hay down for the cows to munch on.
