We have been getting it from a local brewery for about five years. We go pick it up in rolling containers once a week. We supply the containers leave 20 pick up 20 or whatever they have for the week. When we were offered the opportunity we sent samples to Auburn to have it analyzed. We wanted to make sure it was worth the time and effort, based on the report we received from Auburn we have continued using it. The plus is free and a good feed not a complete feed but worth the effort. The negative is labor intensive, it only last a week in our heat and humidity. Another drawback is the brewery tends to have a lot more available in summer than winter. We really don’t need feed in Summer we have plenty of grass, but it has to be picked up year round, so we feed it to bred heifers. The cattle love the stuff.
