First, I would never recommend getting a calf from any other farm to graft onto any cow. Even though your cattle are healthy & the other farms has healthy cattle, each farm has it's own set of "bugs" that your cattle have developed immunities to. Your set of "bugs" are different than the neighbors' "bugs". Therefore, your neighbors healthy calf comes to your farm carrying "bugs" that your other newborns do not have immunities from & the rest of your calf crop can get sick.
Second, if you have a twin, you can steal one & graft it onto your newly calfed cow. There is a product called "O-No-Mo" which used to be called "OrphanNoMore". It is a powder that you sprinkle all over the calf & on the cows nose (if possible). Cows can't resist licking it. If she licks the calf, she will usually accept it. It is inexpensive & I think all farms with newborn calves should keep on hand. I rarely need it, but when I do, I don't want to be looking for a place to buy it. Also, after the calf has sucked the cow a few days, the calves secretions smell like the cow. You only have a day or two to get a new calf on her, unless you milk her out to keep her milk production going.
