Copper deficiency?

[Nanno]

Poor little guy! I wonder if his mother was copper and/or selenium deficient when pregnant? If he was always a "poor doer" there may not be a whole lot you can do to make up for problems that may have started in utero. If he rallies when dewormed then goes back downhill soon afterwards it sounds like he's completely unable to ward off parasites on his own. I know copper deficiency can really open them up to parasite attacks. I'm not sure if it's safe to keep loading him up on it though. Have you treated for cocci? Has he gotten probiotics after deworming? It's possible that the treatments stripped too much of the good bacteria from his gut. A fecal exam for worms and cocci could really help you know what you're dealing with, and those usually come back within 2 - 24 hours of dropping them at a vet. It wouldn't hurt to call around and see if any of the vets in your area will do a fecal for a goat and how much they charge.
