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
