Ok, this is a question that I have had for some time now. Were do we draw the line at supplements? If you are feeding a good feed, have your minerals, maybe something to promote hair, isn't that enough? When do you go over the line. All of these products sound great - but how much do they really work? Right now we are feeding purina feeds, we add oil because we are pushing for weight, we have added glu-coate (which has some cellarator product in it) and we will probably add something to promote hair. I'm still undecided but it will either be gro and shine, epic or shag. Isn't that enough? At what point do you defeat the purpose? I mean we could still add opti-flexx, champions choice topdress, cellerator, etc... and the list goes on. Geez, I forgot that we are also feeding winning fill once a day as a teat! For those of you who have used this cellerator product, what improvements do you see?
