Boost should be mixed directly into colostrum and given as the first feeding. Mix ½ pound of Boost with one gallon of warm colostrum. Stir until completely dissolved. Feed to the calf in one feeding via nipple feeder or esophageal feeder as soon as possible following birth. There is no need to warm colostrum that has just been milked from the cow. If colostrum has been refrigerated or frozen, it should be warmed to 105°F/40°C before adding Boost.
