VVV Episode 8: Age Verification in Cattle

Dr. Jelinski shows us an easy way to estimate the age range of cattle by examining dentition.   Ruminants are unique to other species in that they do not have a top row of incisor and canine teeth, but instead a dental pad used for grinding rough forages. When examining dentition to determine age, we examine only the bottom incisors and canines teeth, as they each have distinct times that they erupt. Just like humans, calves have a set of smaller, temporary “baby teeth” or milk teeth that are present within the first month of life. This set of baby teeth  consists of 6 incisors and 2 canines. As a guideline, aging cattle...

VVV Episode 7: The "Almost" Castration

The other day we were called out to perform a routine castration on a miniature horse… or so we thought. We performed a physical exam on the little stud and determined that he was good to go ahead with the surgery.  We administered his pre-anesthetic drugs to make him a bit sleepy, and proceeded to palpate the inguinal region. What we found there was not quite what we expected: there was only one testicle in the scrotum. This little mini is a cryptorchid. Cryptorchids are intact males with one or both testicles absent from the scrotum. Cryptorchids are still producing the same amount of testosterone as a normal intact male, but they...

VVV Episode 5: The Art of Bovine Necropsy

It is not very glamorous… But it is necessary. The bovine necropsy, or post mortem examination, is done in order to determine why the animal has died. This involves a lot of physical work, and some really keen pathology skills!  It’s an examination that our practitioners perform daily, so it is something we encourage our students to practice as much as they can while they are with us. Meet Amber, one of our newest UCVM 4th year students on rotation who is very smiley and eager to get started!

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...

VVV Episode 4: It's Branding Time!

  Lets hope Dr. Dorin is a better vet than he is a roper!  

VVV Episode 3: Miniature Donkey Post-Anesthesia

We were called out to perform a routine castration on  a miniature donkey. Donkeys, especially miniature ones, are very resistant to anesthesia and so to compensate, veterinarians must give a stronger dosage to donkeys than they would a horse for the same procedure. Check out this little guy as he wakes up after his anesthesia.
