There will be new breeds of cow quite unlike what we are currently used to. Pigmie cows will reach maturity more quickly, and give ready tenderised meat, due to meat tenderiser enzymes being genetically engineered into the cells and released on cell death. Higher milk-yield cows which have a hump rather like a camel on their back, though early incarnations of this technology will require puncturing the skin with a large hyperdermic to extract the milk. There will no longer be a point in dosing cows with Bovine somatotropin because they will produce it at elevated levels naturally.
