But of course they'd love it. Herd animals generally enjoy contact with each other (licking, using someone's shoulder to rub their face, etc.). Hard to interact with each other much when kept in factory conditions, or take advantage of twigs and tree bark to scratch those hard-to-get-at itches. The benefit comes more from psychological health than improved blood circulation, I'd bet.
