A calf should be given milk (non-pasteurized) until it is around 3 months of age, not after so many days.
No, absolutely not. A calf should be given milk formula designed for calves and calves ONLY, not for human babies. You could kill a calf if you give it baby formula because it lacks certain nutrients that calves need that human babies don't need or need less of than a calf does.
When she is obviously having troubles pushing out her calf, or, she's not progressing any further in her efforts to push the calf out of her after some time.
Only give Oxytocin when it's necessary, don't give it just because you can. You should really talk to your vet about this, and consider selling off the cow if she can't produce milk for her calf. You'll have to bottle-feed the calf yourself if Oxytocin won't be enough to help the cow give enough milk for her calf. So please, do your animals a favour and talk to your local large animal veterinarian.
No.
If by "injection" you are referring to artificial insemination (which is not considered an injection when breeding cows), and it has been only 282 days since she conceived then you are being too impatient. The normal gestation length for a cow (on average) is 285 or 286 days long. Gestation, however, ranges depending on the cow's breed. She can give birth at any time between 275 days to 300 days of gestation. So I suggest you be patient and let Nature take its course. Your cow will let you know when it is time that the calf should arrive.
NOTHING can or should replace Colostrum when feeding a newborn calf. You MUST feed a new baby calf colostrum within 24 hours after it is born. There is nothing man-made or similar than can replace colostrum.

According to my calculations, George Washington felt that citizens should give their loyalty to the nation as a whole.
That all depends how much calf-muscle exercising you do. If you do Pointe, your whole leg will get strong--but not bulky. Ballet doesn't really give you hulking muscles.

Absolutely NONE. Do not give any pain meds to a calf if it does not need it.
