This maybe like trying to compare apples and oranges. Back when I showed (20 years ago) it was a no-brainer. Hogs were definitely easier. Nowadays, with mixing all the additives in with feed, especially from 150 pounds on, and all the exercising you need to do, takes so much more time and effort than meets the eye. Oh, and then if you have a white hog that you want to stay white, you need to keep them on concrete with 6" or so of woodchips that you have to clean out once a week, along with washing the pig once a week. It doesn't make much sense to bring a dirty pig back into a $70.00 pile of clean wood shavings.
If the ratio of cattle to hogs is 1 to 1 or even 1 to 2, I would say hogs are easier. Any more than that, and I say it is a push. Especially for the last 90 prior to show. As far as feed cost goes, (with additives) I can feed 2 1/2 pigs for 6 months for the same cost that I can feed 1 steer for a year. Isn't that nuts???
Funny thing is, at our county show last week, I walked through the pig barn several times. Each time, there was at least 1 hog squealing at the top of its lungs. Going through the cattle barn, the loudest thing I heard was a fan.
Anyway, 1 year from now I will be able to give a detailed report on which is harder.
