mls, I'd like some more info on that please. Could you give me a link to a page that has info on it or something? Anabel, what I mean by 'not feeding it to experiment' and 'wanting to experiment' with one kind of grain is that I'm not feeding grain in general to see what happens. I want to switch grains to see if he does better on a different kind because I feel like he's lacking something with the Purina Strategy. And he's only getting ridden 2-4 times a month RIGHT NOW. He gets ridden 5+ times a week in the spring, summer, and fall. My trainer had me put him on grain in the first place because she said it would give him some 'roughage' (which I disagree on because hay gives them roughage.) I was thinking about switching him over to just beet pulp, but some posters said it wouldn't give him the nutrients he needed whereas grain would. I said in one of my comments that he was a tad underweight, you probably just missed it.
Bolded statements are directly contradictory.
Yes, so RIGHT NOW his nutritional needs are that of a horse being ridden 2-4 times monthly, not that of a horse being ridden 5 times a week.
I have read all your posts and have not seen where it was mentioned the horse is skinny, only that he is an easy keeper. Mind you I may have skimmed some of them.
So your trainer wanted the horse on grain, and you didn't, and now you want to put him on more, different grain?? Ok...
Grains have a lower nutritional value for horses than beet pulp or rice bran. The only thing really with "nutritional value" is a vitamin and mineral supplement, which can be fed loose. Grains, generally, are too high in sugar and starch for horses not in hard work. Ideally a horse doing what your horse is doing currently would need hay, loose mineral and water. If he is not sustaining himself on that, then add hay, or a ration balancer, like beet pulp.
What makes you feel like he's "not getting enough" from his grain now that you want to change it? 2lbs is a small amount and he will be getting most of his nutrition from the 20lbs+ of hay he should be getting daily.
