I have a 2 week old orphaned Boer goat - currently he is on Di-vetalec formula from the vets and I am wanting to change it to Profelac milk replacer which is more targeted at kids and lambs.... We have already had issues with scours and he has had 2 lots of antibiotics for infections. Currently he is ok although has a sore hoof which we have strapped to help heal. My question is: should i be slowly moving him over to the new milk replacer? 1/2 and 1/2 in the bottle for a few days?
