You are already done with her but when trying to get a calf to nurse on an uncooperative cow, Rompum (sedative) is your friend. 1/2cc to a full 1 cc will mellow her out enough to make it easier to get the calf to nurse. Also seems once they go to sleep and wake up its like it resets their brain or something, they are more willing to accept the calf. Our vet also mixes up a calf claim concoction that is mix of Rompum, Oxytocin, and some other stuff. Mellows them out, helps them let their milk down, and helps kick in their motherly homomones. Seems to work but sometimes I like straight Rompum to knock their ass out.
Definately sell that cow, either now or as a bred one later in the year. Normally I myself would never breed a cow like that and sell her as a bred one. I figure If she is to goofy for me I don't want someone else to get stuck with her either.
As for the bottle calves I think you made the right choice by selling them for the money you got. You'd have alot into milk replacer and calf feed that you probably wouldnt' make any money on them and you'd have alot of labor into them. What we usually do with bottle calves is usually feed them until something else loses a calf and then adopt them onto the cow that lost her calf. Sometimes it goes good, other times you wish you'd have just sold the calf and the cow.
We're calving right now and it was a nightmare this last week with temps in the teens and 20s with a nasty wind chill. Everything that calved had to be brought into the barn for a day before going back out. Going to have some calves loose some ears even though I brought them in as soon as they hit the ground. Had a tiny calf that was born a little early get chilled. Warmed it up, fed it colostrum replacer, took about 3 days till it could stand good enough to nurse. Got it sucking on the cow easily. Next morning calf was doing great, that afternoon calf was dead, figure the cow might have stepped on it in the pen. Wish it would have just died right away and saved me all that work, but thats the way it goes sometimes. Dad had a cow that had twins that same day so we adopted one of the twins to my cow. Weather is warming up now with highs in the 50s and won't even go below freezing tonight so calving will be alot easier now and alot more sleep.
