This depends on when you first put the calf on the bottle. But mainly, it'll be a few months that a calf goes from being dependent on the bottle to being fed as a feeder calf.
A few weeks. Often the calf will die of starvation before then, if you either don't milk the cow out and tube the calf with her milk, try to make the calf suckle as much as you can, or if you don't bottle-feed the calf. So make sure you are caring for the calf if the calf can't suckle from his momma.
It all depends on the breed, the genetics of that calf, the health of the calf, and the quality/type of feed you're feeding it. Thus it could take anywhere from three months to eight to get a calf to be at that target weight.
feeder mice will tend to live a maxium of 3 years. As long as you take great care of them.
The umbilical cord is ruptured when the calf is born. The remainder of the umbilical cord will fall off the calf after a few days.
I had a woodpecker on my suet feeder the first day I put it up, but it may take a few days, they can't really smell it so they need to come to the tree you have it in and find it.
it takes thousands of years for a water bottle to decompose.
how long does it take pseudomonas to grow in a bottle of water?
400 years

Unfortunately, the heifer is very unlikely to accept the calf back at this point. A mother cow bonds with her calf within the first few hours after birth; if this was disrupted, the cow will reject the calf if reintroduced later. Also, if the cow has stopped lactating, she is very unlikely to restart lactation.
