So how much of the 19% protein is from BSFL?We had the same conversation when Purina put out there first free-range feed with BSFL. I am not a fan of Purina, I think they are overpriced, but I applaud them for starting to add BSFL to their feed. Most feeds are !00% vegetarian. I think most people would look at this feed for the higher protein for their layer flock. I would buy it depending on the price. Hardly a ripoff simply because they won't reveal their proprietary info.
