Your facts may as well come from PETA... They are biased and I'm very certain your milk quantities are incorrect. I come from a commercial dairy farm in Wa and our highest producing cow ( and these were well bred cows) gave 40 ltrs occasionally, it is not a constant thing and feed, temperature, where the cow is in her cycle and the season are all factors in this. So a range of 35-50 per cow is just so very wrong.
