Definitely not OK.
One cow (taurus, big tits) produced 5 milk, the other (Tisha) producted 1200??? No hyperlactation. None of them are futa, but both are being bred and 600 semen was collected from each. I'm going bankrupt by buying bottles.
Also, profits are weird. 10 empty bottles are 100 gold,I seem to be losing money if 54 bottles yield 270???
Seeling them directly on the market seem far better.
