I feed a balancer because Tia is now only fed haylage and a few nuts (not the recommended amount).
I have always had Tia on pink powder, but spoke to NAF when this product came out. They said it was worth changing over from Pink powder because it has almost the same ingredients (just a couple of things missing) but would work out much cheaper for me.
I shared a tub with another lady on the yard, but unfortunately Tia didn't like it (she is very fussy with supplements - pink powder is the only thing i've managed to get into her). The other lady's horse loves it, and has been less stressy since she started on it, and has stopped cribbing.
One of the older horses on the yard has changed over, and his poos have become much firmer on the haylage balancer.
