I did over 50 fawns last year usig pastrized goats milk. They grew great. Bucks and does. I'm switching to Fox Valley this year because i plan on doing over 100 fawns this year, and its just too difficult to keep that much fresh goat milk on hand. I went through 80+ gallons a week last year.
I don't think what product you use to feed to your babies is as important as making it consistant and spending alot of time with them. I can imagine Having a fulltime job and feeding fawns 4x a day can make you a nervous wreck! I always thought that trying to get them to eat feed was the most important part of the whole process. If I can get them to eat feed 1/2 way though the bottle feeding process, then they are going to grow. Regardless of what kind of milk of how much I am giving them.
The key is, get a routine that works, stick with it, and have luck on your side!
