Calf’s Choice Total Gold has a high concentration of bovine IgG and is intended for calves needing extra immunity. Gold is a natural bovine colostrum powder that is rich in colostral fat, a critical early source of energy and warmth for newborn calves. Gold is made only from natural, premium quality bovine colostrum and is free of disease causing organisms that can be transmitted in colostrum. It is an excellent source of IgG, colostral fat, growth factors, and nutrients needed to improve calf survival, health, growth, and long term performance. Gold is not a manufactured formula based on blood serum, whey, eggs, vegetable fats or other ingredients not naturally found in colostrum. Calf’s Choice Total Gold uniquely holds USDA Veterinary Biologics Regulatory approval for use as a total replacement for maternal colostrum in calves as an aid in the treatment of failure of passive transfer.Gold may be used to supplement or completely replace maternal colostrum and easily mixes in under 15 seconds. To achieve a replacement dose, feed 2 bags (120g IgG) and for optimal calf performance feed 3 bags (180g IgG). If supplementing, feed a minimum of one bag (60 g IgG) in addition to sufficient maternal colostrum to target a similar overall mass of IgG.
