Bovine lymphosarcoma

摘要

I lost a 6-year-old cow this summer. She started to lose condition and was a couple of condition scores behind her herdmates when we put in the fly tags in early June. There was nothing really remarkable on a physical exam at that time, so we repeated the endectocide treatment from earlier in the year — thinking we may have missed her at turnout — and then kept an eye on her. She was still making lots of milk and her calf was doing well.
