To Farm Animal Owners/Handlers

Options
What do you log your activity or exercise as that is equal to the type of work required to take care of animals?

I don't do it on a regular basis but as an Ag major, I work with farm animals often enough to know I feel cheated by not logging the time I spend handling farm business as SOMETHING. All of you that have ever done any work with cows, pigs, sheep, and goats know what I mean.

Any suggestions on how to log it? Or the general break-down of the METs of an activity?
