Heat Treated Colostrum Wins Again!
In a recent research report efficiency of antibody absorption was compared between raw and heat-treated colostrum. Here are the facts (112 Jersey calves):
Heat-treated = 37%
Raw = 32%
Average serum IgG concentration in the calves reflected this difference in efficiency of antibody absorption:
Heat-treated = 40mg/ml
Raw = 35mg/ml
