The problem is that increased muscle mass on bones and tendons that are not made for that muscle mass may in fact results in problems for the cow, we would need to select better bones via DNA, etc...
I'll give you the example of chickens, chickens meant for meat grow so fast but so fast and so much that their legs can't withstand their weight sometimes...
I think the future isn't this... the future is to grow steea without the need for animals, probably via microbes, etc... much faster and, in the future, less expensive without the need for large pieces of land dedicated just for cows
And even further in the future a 3D printer that prints out our steea
Another problem with super cows in the near future is that they would need more food, which would mean we would need faster crops, faster rain, which in turn would put a lot of stress on the land, we would need to speed up nature... what we should first try to do is decrease the amount of methane the cows release daily, to decrease pollution
Regarding the strawberry milk part, i would love a chocolate protein shake straight from the cow, imagine how awesome it would be xD but i guess the increase in protein content might solidify in the cows tits and increase the probability of infections
I'm putting so much thought into all this... Overthinking much :P
Haha, that is OK. I was wondering about the bone thing as well. Many cows are raised in feed lots where there is little to no room to roam which would be even more problematic with the extra weight.
I'm seeing more alternate milk products. They are made from soy, coconut, or almonds. We never had that when I was a child.
