Subject: RC: Re: Cotton seeds in beet
pulp
Well, it's not ideal, but really not a big deal
unless you were feeding tremendous amounts (which I assume you're not).
Unprocessed cottonseed, or to a lesser extent cottonseed meal, contains a
substance called gossypol which tends to bind to amino acids, chelate iron,
etc. It would be a bigger problem in a young animal, but usually not a
major concern in adults in the amounts your horse would be eating. The
safe upper limit for a healthy adult horse is about 10% or so in the
diet---around three pounds or so.
Don't get me wrong, gossypol IS a concern and I
would never recommend cottonseed as part of the usual diet, although diets
*can* be formulated to use cottonseed meal as the protein source. If the
cottonseed component of your beet pulp is less than 20%, and your not feeding
more than ten pounds of beet pulp a day, then I wouldn't lose sleep over
it. But maybe your feed store manager could find a supplier that sweeps
out his bins a little better. You might also ask if the same mill also
manufactures feeds for cattle, especially ones that contain ionophores,
Rumensin, Monensin, etc. If something like *that* got into the food you
fed your horse, that CAN cause major, major, life-threatening problems, and it
wouldn't be the first time horses died because they were accidentally fed a
cattle feed. There was a big barn back East that lost a couple dozen top
show horses because of such an accident---so wouldn't be a bad idea to ask
your feed store to check into it, and if the same mill also makes cattle feeds
with ionophores...well, I'd probably ask for him to order you a different
brans, or skip feeding beet pulp from that source altogether.
Good luck,
