There is a difference in colostrum replacement and colostrum supplement. The replacer has a full spectrum of all needed things that are in colostrum... the supplement is about 50% strength or thereabouts. It is good for a baby that the cow is either not making much, or in many cases of dairy animals, the colostrum does not rate high on the colostrix meter... If you got a full bottle of replacer in the calf, then the supplement will be much better than nothing. I would definitely get her in a chute, see if she has milk... and go from there. If she doesn't seem to have much milk... then a couple of days of shots of oxytocin will help her with let down and to come to her milk better.
Just had a cow have a dead calf... wasn't even sure it was hers because NO UDDER... but she stayed with it and mooed for it. Got a 2 day old calf off a dairy that had colostum, to foster on her and it took 4 days of in the chute giving her oxy; but she now has a bit of an udder and calf looks like he is getting enough. After 3 days I gave him a bottle the next 2 nights to make sure he was getting a full tummy and the 2nd night I gave him the bottle, she looked like she was making more of an udder and today, after 9 days, they went out with the other cows. She fully accepted it 2 days after we introduced them... was great about it... but not hardly any milk. I think now they will be okay. I wanted him to really work on her udder to get her to come into her milk... and she has.
