>>11415350>As interesting as wondering what traits a dairy cow crossed with an angus might possessKnow someone who did this a few times, they bought beef cross heifers because they were cheaper than dairy heifer calves, they'd milk them a year or two then sell them for beef
as ever with these cross breed systems they're a bit of a chaotic mixed bag when if you start crossing F2, there are rotational cross breeding systems using cycles of different pure breeds with interesting results but you still need a source of pure genetics to make them work.
old landraces are a bit more resillient to admixture but still fragment if there's too much.
