A five-year old Holstein cow is presented with a two-day history of being off feed and a precipitous drop in milk production. The cow stands with abducted elbows, an arched back and is reluctant to move. Physical exam shows intermandibular edema and bilateral jugular distention. A grunt is heard when pressure is applied to her xiphoid and there is a washing machine murmur (almost like splashing sounds) on both sides. There is little rumen activity. What is the recommendation for the farmer?

A - Treat with high-dose penicillin/streptomycin
B - Check the feed for excess monensin/lasalocid
C - Test the herd for bovine leukosis
D - Check the feed for cottonseed meal (gossypol)
E - Cull this cow
