We did graft a calf on a cow that had twins doa, but that was a new sale born calf, not an older calf. We rubbed membranes from the dead calves on the adopted calf, locked them up together and then when the calf was bawling trying to nursse, we stood there and wacked her/scolded her everytime she kicked the calf. She finally took the calf.
That same cow had twins 2 years later, and she would not let them nurse..We put her in the chute, locked her up with them and she never accepted either one. Because of circumstances, we quit trying and I bottle fed the calve. The twist to the story is that is the first cow I culled/sold.
I shouldn't have made it sound like the cows were so easy...the cows did resist. The first cow I sold, her calf was 4 months and in the feed bowl, so I wasn't worried...she just kept trying and sneaking until finally Lucy gave in and accepted her. As far as Lucy letting the 3rd calf nurse, I can only say that she has let that particular cow's other bull calves sneak milk from her before (a few years ago).
The second cow, whose calf was just 7.5 weeks was not eating food. I bought milk replacer and tried to coax her with the milk, squirted her with the bottle, left a bucket out, she would have nothing to do with it. She tried to steal milk from almost every cow...and she took alot of rough knocks. I thought for sure she would get weak and then I would get the replacer in her. My husband told me not to worry the herd would take care of her. Before I knew she was getting milk because of flies on the face and that milk look they get on the face. I had 2 other cows who had calves similar in age, I figured she was sneaking. A few weeks ago the same cow letting her nurse was kicking her butt and good. Apparently the cow gave in.
For me this year it was good and I think helps the calves gain better. donna
