[QUOTE="Anonymous, post: 10055"] Cows that twin and their female offspring (the ones that aren't Freemartins) do have a slightly higher rate of twinning on subsequent calvings. But, (there is always a but(t)), even in herds that have genetically selected for twinning the insodence is only around 60% or so. However, (there is frequently a however too), some cows repetitively twin and their daughters will have the same likelyhood. That is the reason the herds that purchase outside cows for thei twinning herds want those that have twinned at least twice. I suppose if you had a herd of cows that regularly twinned you could basicly run two herds, that way you could feed the required supplements to the twinner cows and not to those that had singles. You would have to move the cows from herd to herd based on how the calved each year but when they get preg checked you could move them at that time and give those carrying twins added nutrition.
