I started feeding beet pulp to my now 30 year old Tennessee Walker about a year and a half ago and highly recommend it as an affordable way to keep weight on your senior. The amount you feed depends on whether you're using beet pulp shreds or beet pulp pellets. If you have the time to soak them, like at least 2 hours to over night, pellets are definitely more affordable and you get more weight per bag. The shreds take much less time to soak (15-20 minutes) but you'll go through a bag much faster. I try to have a bag of each on hand. I use the pellets when I'm home and on a regular feeding schedule. The shreds are my back up if I either forgot to soak pellets in time or if I've been gone all day. As far as per feeding, I measure out one small coffee can, like the 1 lb can not the big 3 lb. Folgers can from the video of pellets per feeding which weighs a little over 1.5 lbs dry. I then add about 2 of the same cans in water. If I'm using shreds, about 2 of the 1lb. Coffee cans of shreds equal the same as one can of pellets. And then for shreds I add water till the water line is just above the shreds. I just eye ball the water now but that's always a good rule of thumb to go by when you're starting out. And then I add his regular senior amount to that bucket of soaked beet pulp at feeding time. It'll look like a lot after it's been soaked but beet pulp is considered a forage like hay and you can't over feed it like grain. It is an excellent way to keep them warm in the winter and like she said in the video, when hay prices were crazy last year for us in Texas, I cut back on hay and put all of my horses on beet pulp. They all remained fat and happy. And our senior, who doesn't eat any hay at all anymore, looks better than ever.
