Cows treated with rBST are probably not producing milk that is distinguishable from untreated milk but I oppose it for two reasons. 1. The cattle have visibly lower welfare. They carry heavier bags, they have more frequent infections. 2. The farmers are already in a situation of low bulk milk price and high cost. Margins in dairy farming are frequently negative. This increases cost to try to produce more output per cow, which is a beggar-thy-neighbor approach. If everyone does it, milk prices go down even further. I don't know enough about ractopamine to have an opinion.
