Petlurv, for people like ourselves, I cannot see why we can't use goats milk and turn that milk into yogurt with the added benefit of removing the offending bifido strains altogether. I see that Custom Probiotics have a rather good powder with none of the offending strains mentioned above. I've been using CP yogurt starter culture formula 1 with some success. The product contains L. Acidophilus, S. Thermophilus and L. Bulgaricus starins. I decieded to buy a yogurt making machine and get some goats milk and get making some lovely yogurt. It's much easier on the bowels and gets the strains into all the right places. Seeing that goats milk is far less allergenic than cow's milk why not give this a go. C
