USE IT!!!!! It is a great product. We used it last year, started about May. We had a hereford heifer up at Michigan Beef Expo, we started feedin in may like I said, and come state fair time a very reputable breeder from Indiana, came up to us when we were down at state and said he'd never seen someone put bloom on a heifer that fast. Now we feed it all year round to all the calves. It is an awesome product, extremely palatable, keeps them on feed in high times of stress, increased in our rate of gain (but that has a lot of variables), and really gives a nice shine to their hair coat. It runs about 21$ a bag here, but imo it's well worth it.
