How many hours after delivery is colostrum collected?

Essens Colostrum is collected as a rule from the first yield (first milk yield the moment after the calf is born).
Usually two milk yields occur within the first 12 hours. The second milk yield, however, contains about 47% to 53% less immunoglobulins than the first and with following yields the content is further reduced. Therefore, if competition guarantees the first 12 hours, they forgo further yields. With ESSENS Colostrum we guarantee our source is solely from the first milk yield.
