well if you want good quality milk you will have to go outside the US to a farm. the milk in the US by law is pasturiezed and zapped to high heaven.
also the cows are given hormones to produce as much milk as possible.. go to a dairy farm and see how it works, you won't want to even drink again after you see in person how it works. the reason milk bloats so much is because of the lactose which 80% of humans cannot digest (we did not evolve to drink cow milk, we evolved to drink human milk.. humans did not start drinking cow milk till the turn of last century on a high basis due to the boom in dairy farms in the US, it was a ponzi scheme in the midwest and many German and Irish immigrants got into the business and it exploded) so it sits in the stomach and bacteria goes to work on it causing bloating and gas.. so of course you will gain weight on it. if you are ever comping a good trick is to avoid all dairy (yes even whey protein for that entire week).. you will dry out bigtime.
if you insist on milk your best bet is hemp milk, or find a farm that sells fresh goat milk, much easier to digest/less bloaty
