Cattle Case: Jejunal Hemorrhage Syndrome

Crystal Riczu, ,  March 2013   HISTORY Last year, a 3 year old Angus bull (Bull 1) was presented with anorexia, weight loss, and dark tarry feces. A comprehensive diagnostic work came back inconclusive. The bull was treated with gastroprotectants, seemed to improve over the next month, but then was found dead with no significant post mortem (autopsy) findings. Two weeks ago, Bull 2 (a 2 year old Angus bull) also presented with anorexia, weight loss, and dark hemorrhagic diarrhea at the same time that Bull 3 (a 2 year old Angus bull) who had been losing weight over the winter, seemed to “not be doing right”. Over the next week the...

Calf Case: Femoral Nerve Injury

Monica Kovacs: ,  March 2013 | Edited by Jennifer Enzie and Cody Creelman   Case Presentation: In mid-March we received a call from a producer at a commercial cross cow-calf operation asking us to check out a 3 week old calf. When we arrived, the calf was lying down and sleeping comfortably. When prompted to stand, he got up and was bright and alert, however, he only bore weight on his left hind leg. From taking a thorough history, we learned that this calf was fairly large at birth and so his dam, being a small heifer, had trouble giving birth (dystocia).  He was a hard pull because he was “hiplocked” for a period of time....

VVV Episode 6: Mystery Cow Case

We were called out to visit a cow that was suddenly found down on pasture. From taking a thorough history, we found out that she was 3 weeks postpartum with no previous medical history or any suspicions of illness. The pasture the herd is currently grazing on was seeded 3 years ago with a mixed grass seed and was not grazed on last year. Therefore, grass was overgrown from the last year as well as lush new spring growth from this year following a period of wet, cool weather.   The cow presented with the following clinical signs: recumbent rigid muscle tone with clonic spasms and twitching opisthotonos (posturing with head and neck rigidly...

Mystery Calf Case

A call was received from a cattle producer with a herd of 75 crossbred cattle in the foothills of Alberta. The calves in the herd were 3-4 months old. The dams were vaccinated in the fall at pregnancy check with a killed 6-way respiratory vaccine and a 7-way clostridial vaccine. The calves were never vaccinated and were in excellent apparent health up until 4 days ago. Upon checking his herd, the farmer noticed one freshly dead calf. Two other calves in the herd appeared mildly depressed, with one having a slight swelling over one shoulder. The farmer decided to check them later in the afternoon. On the afternoon check, the calf with the...

Syndactyly in a Miniature Hereford Calf

Former UCVM student Dr. Adrien Perez and Dr. Cody Creelman were called to a farm to treat a case of retained placenta in a miniature hereford cow. The cow had given birth 2 days prior to a backwards calf, which had to be pulled. This calf had not stood since being born, and its owner had been tube feeding it colostrum and then milk from its dam. After treating the cow, the owner asked to have the calf examined. Upon physical examination, it was noted that the claws of both front feet were fused together, as was one hind foot. This calf was then diagnosed with having syndactyly. Syndactyly is the term used to describe when the digits of an...

Feedlot Mystery Case

The pen checkers came in late morning and said there was a steer down in a recently placed pen of calves.  The steer was down on its side and all four legs and tail were stiff and extended.  He seemed alert, but would not even attempt to rise.  The pen had been received the usual processing protocol including 4-way MLV and low dose 7-way Clostridial vaccines.  Any intact bulls, including this animal, had been band castrated.  He was treated for nervous disease, but died overnight.  Two days later another steer was walking stiffly and despite being treated, developed similar symptoms and went on to die.  A veterinarian was called and...
