Alrighty, I will just leave him on his beet pulp then. Thanks Peggy, you came thru for me before when I first got him and he has gained a lot since then.
Alfalfa has better nutrition than beet pulp and is high in amino acids, which are needed to build muscle and gain weight. You can feed up to 8 lbs of alfalfa daily for most horses, without any risk of colic or founder. Many horses do fine on even more. When I lived in your area, I fed AM and PM hay as straight alfalfa (worked out to about 10-15 lbs a day), with lunch hay of Bermuda (about 5 lbs). No grain, just beet pulp mixed with rice bran and a vitamin supplement. It worked well to put weight on my OTTB.
However, with the things I have learned since then, I agree that free choice Bermuda is better, with Alfalfa to supplement that. Alfalfa has more nutrients and amino acids than Bermuda, which helps to fill in those nutritional gaps.
Feeds and grains are high in sugar and energy. It's like giving a kid a power bar and a coke. He'll have enough calories and nutrition, but he'll be bouncing off the walls
. The more feed you give a hot horse, the more hyper they become, the more the metabolism revs up, which makes them burn more energy, which makes them need more food. It's a viscous cycle. The only way to break it is to stop all "hot" feeds and go back to a forage and fiber based diet.
Make sure your beet pulp (and alfalfa pellets) are the kind that do NOT have any molasses in them.
