I'm glad it's been dropped but it's already here.
Last year, working for RHET, I visited a few dairy farms. It wasn't unusual for the cows never to be at grass while in milk; some, but not all, were turned out during their dry period, but that depended on season, type of land etc. The highest yielding cows CANNOT survive on grass - they are genetically programmed to produce so much milk that they would, literally, milk themselves to death, so on most dairy farms the high yielders at peak lactation will be kept in.
So don't kid yourself that factory dairy farming has been averted - it hasn't. But if the consumer wants to buy 8 pints of milk for £2, that's the way it will be.
