With every wheel of Ralgro®, cow/calf producers conserve valuable land and water resources. And the heavier weaning weights that Ralgro provides help sustain your ranch so you have more to pass on to the next generation. Put Ralgro to work for you and your future. Talk to your veterinarian or your local Merck Animal Health representative about Ralgro. A withdrawal period has not been established for Ralgro in pre-ruminating calves. Do not use in calves to be processed for veal. For complete information, refer to product label.
