This feed is a texturized feed, made up of steamed rolled corn, steam rolled barley, and soybean meal pellets. However, we also feed a fairly high fiber, low protein hay to them, as opposed to a high quality hay. You only need to be concerned with Vitamin E if you are also supplementing with selenium. We feed so that our llamas get 500 IU per day. Vitamin E must be given with the selenium, for it to have its beneficial effect and it must be fed at fairly high levels to do so.
Thiamine is needed mostly in areas with hot, humid summers.
We feed so that our llamas get 250 mg per day. While llamas are inexpensive to keep individually, having a herd makes costs add up. We feed about a ton of feed every 6 weeks. You may wish to know why we don't get these useful vitamins and minerals into our llamas via a salt supplement instead. We don't use salt supplements, as we feel this can result in very uneven delivery of nutrients to different llamas.
