I was thinking on getting a milk goat insted of milk replacer. any thoughts on this?
I would be careful going this route. Goat milk is richer than cows milk, and can cause problems.
Do i need hay or alphalfa?
I would start them out on a small amount of good grass hay, then start alternating grass with alfalfa every other feeding when they hit a couple of weeks old. Reason being - grass will help to regulate their digestive system, and will help to offset some types of scours, whereas alfalfa's protein content can be a source of scours in itself if the calf is not used to it.
What type of grain or mix when ready?
You can either buy some type of calf starter, or you can use a 3-way grain mix (corn, oats, and barley mixed with molasses is the usual one around here). Keep a small handful out from day one, and stick a little bit in the calves mouth after you've bottled them. Keep it fresh, and you'll have better luck with them eating it.
Medical stuff that i need on hand?
If you're careful, don't overfeed the milk, keep the bottles/nipples clean, provide some type of shelter with a good layer of straw/old hay(depending on your location/climate/temperatures), and don't put them in a pen that has been recently occupied by sick calves, you might not need any medical stuff. Good luck if you do choose to go this route. It's time consuming, it can be nerve-wracking, but it's also very rewarding and fulfilling.
