Thanks to all of you who gave advice on putting weight on the new OTTB...its working! :) The first pictures are the "befores" from the first day I had him in January and the last ones were from today, the "afters".
He is on free choice Bermuda, also gets 1 flake alfalfa and 1 flake bermuda in the morning, 4 lbs beet pulp, 2 cups rice bran, vitamin supplement, and then 2 flakes bermuda at night.
The person who had him before me fed him 1 flake in the morning and 1 flake at night of alfalfa.
Anywho, thanks for the advice, its working :)
