We have had a continuing problem with diarhea in our dairy goats. We have a Saanen doe, Saanen buck, a Nubian doe and a five month old Alpine doe that repeatedly have diarhea. When this comes on milk production goes down,in the milkers, and the appetite is nearly nonexistent. We have a five year old Sable doe, a five year old Alpine doe and a seven year old Alpine that do not get this condition. A year ago a local vet said it was Coccidiosis and prescribed Corrid. This seemed to work last year. However, this summer and fall the condition returned and the Corrid does not seem to help. The Nubian and the Saanen doe were purchased last year. The Saanen buck is the kid of the Saanen doe. The older Alpines have been on our property all their lives. Does anyone have any idea what is causing this? or what the treatment should be? We have given all of our goats CD&T shots. Recently we lost a two month old Sable/Alpine cross doe to what we suspect was some type of worm infection. Other than this we have had very few health problems. We have had ketosis and mastitis, but nothing else that we know of. Any suggestions would be greatly appreciated. I have no confidence in our local vets knowing anything much about goats.
