Well yep - Livermore Feed is out (thanks to someone on this board who picked up 10 bags on Friday - but it wasn't me - LOL). Calderons in Tracy is out and Finta is out. But Finta told me today they should have more beet pulp in about a week. But from the diet you mentioned - it doesn't really sound like she needs beet pulp if she isn't needing extra "cool" calories for weight gain or her teeth are bad and she can't eat hay well. Beet pulp and alfalfa hay is providing two sources of calcium. Horses with good teeth really don't need concentrates, just good quality hay or pasture.
