Challenging cases in small ruminant medicine (Proceedings)
Aug 01, 2009
CVC IN KANSAS CITY PROCEEDINGS
This hour of lecture will focus on the art and science of veterinary practice in the context of clinical cases. The following cases will be "worked-up" throughout the hour discussion. Some case history, exam findings, and some of the relevant lab work is presented below.
You are presented with a 4 year old Suffolk ewe for evaluation of abnormal behavior. Four days prior to presentation the ewe separated herself from the flock and was noted to be weak. She has become progressively worse and now has difficulty standing. The ewe is one of 20 on a 30 acre pasture that is cross fenced into 5 acre paddocks. The animals are moved regularly and have routine fecal examinations with targeted worming based on parasite profile and quantitative counts.
You are presented with a 2 year old pygmy goat for anorexia of 3 days duration. The goat is one of 10 goats housed on a 3 acre pasture and is the only one that appears to be sick. The goats are wormed every 60 days with approximately 1 cc/100lbs body weight ivermectin. The goat has been on penicillin (3,000 IU/lb SID) for the past 2 days with no apparent response to therapy.
You are presented with an 8 week old Suffolk cross wether. The wether was purchased 1 month prior for this upcoming show season. It is fed 600 g of a premixed grain ration. No hay or supplemental feed is given. It had one episode of straining shortly after purchase which resolved spontaneously. For the past 3 days the wether has been off feed and straining. He has been treated with ceftiofur and flunixin meglumine with no response.
