For those that have fed beet pulp, how long was it before you starting seeing results when trying to put weight on a horse? I have been feeding about a week (I know that is not long enough to see results) just wondering how long really until I should see some progress?

It was only a few days for my hard keeper. And if I won't keep him on it he loses it just as fast. You might try upping your amount. My horse gets close to 2 pounds a day weighed dry. Soaked for 30 minutes each feeding. 

I saw results after about a month, but I wasn't doing a large amount. I just did 3/4 of a 3qt scoop dry. After soaking I squeezed all the water out I could. Once a day. Mine was 27 when I was doing it and a cushings horse, so my results might not have been the same as a normal horse without special needs. I do always try to give a feed change a full 6 weeks at minimum to gauge results, sometimes even 8 weeks. 

Beet pulp is really high in fiber and not in protein so if you don't see progress after 6 weeks or so you may consider something else.

I'm not a fan of beet pulp but will try it if it helps my Cushings horse. What benefits did you see? How else did you treat him?

My horse didn't seem to be a huge fan of it. he eventually started leaving it and going to steal the food of the other one he's with. I just put him on it to gain weight, he's kind of opposite the normal cushings horse and is usually way too skinny. But beet pulp is a good idea, preferably with the water drained after you soak it. It pulls extra sugars out, but you only have to worry if your cushings horse is starch/sugar sensitive. I just simplified my program to what works for all 3 of mine, Kalm N Ez since its metabolic friendly and they just have free choice alfalfa. Unless your cushings horse is metabolic too, I wouldn't worry too much. Mine has been maintained drug free for 10 years so far on just a lower nsc grain and alfalfa hay. We tried the Prascend briefly, but he went completely off feed on it so after a few attempts at dosage adjustments we gave up
