If anyone caught that Corb Lund reference, thank you.
This placement was a blessing. Last year I was trying to find placements to go to in Australia (we have to do a certain number of weeks in Australia). I was really struggling because I do not have many friends and no family in Australia. At home, it is easy for me to stay with someone I know or visit people in different areas where I might do a placement. It looked like I was going to have to spend a lot of cash to pay for transportation and accommodation to do placements in Victoria. I was chatting to some of the girls from church about this, and next thing I knew, my friend’s mum called me! She explained that her and her husband had a dairy farm in Gippsland and their vet was amazing, very busy, and took students all the time. She had already called someone and vouched for me and they had agreed to take me on as an extra student at Tarwin Vet Group.
The first day of this placement was what I had imagined real Gippsland weather to be like. It was windy and POURING rain and I started to mentally prepare myself for 3 more weeks of downpour. Our first call was to see some sick cows at a dairy. We wore our normal clothes in the truck and when we arrived at the farm we changed into our boots and rubber pants. Classic student… I didn’t realize the side panels on the vet box on the truck flipped up…so while the vet was hiding from the rain and changing in the dry area I proceeded to dance around and struggle to get my rubber pants on over my coveralls as I got progressively more soaked in the rain. I am not meant for rain. The first cow we saw had very bloody diarrhea and very pale mucus membranes. The vet wanted to recommend an exploratory laparotomy (abdominal surgery)—in this case we didn’t think the cow would survive a surgery because of the expected amount of blood loss. We thought she had a condition called jejunal hemorrhage syndrome. We also saw a cow with extremely bad photosensitization—so much worse than any terrible sunburn I’ve ever had, I really felt for that girl. During my placement we had quite a few ‘sick cow calls’ which allowed me to get lots of practice doing physical exams–a few times we were able to give farmers definitive diagnoses, other times the cattle required tests to figure out what was truly going on. I saw a lot of different cases including ill-thrift, lumpy jaw, woody tongue, coccidia scours, pneumonia, bilateral pyelonephritis, and polioencephalomalacia.
We often got calls to see cows and calves with lumps on them! Our first ‘calf with lump’ call actually ended up being the most interesting. Lumps in cattle are commonly abscesses and I couldn’t wait to lance it! But this calf had a large, soft lump down his neck. As I palpated the lump it started getting softer and the calf would walk away and regurgitate up hairball like materials. We spent a while massaging his neck until the lump got much smaller. We suspected that the calf was sucking hair off his pen-mates ears and ended up with a choke-like condition (more common in horses).
Lameness is another common reason a vet may be called to see a cow. We visited many lame dairy cows, and a few lame beef cattle during my placement. Depending on the vet I worked with I got to practice lifting up legs–either with pulleys (much easier) or just ropes (I need to get rid of my noodle arms). On one occasion we went to see a large Angus bull. I learned that a lot of the vets will give a little bit of sedation to the lame beef cattle. Sedation is given to the beef cattle because they are handled less than the dairy cattle and often more dangerous to work with, sedation can calm them down and allow us to safely complete a full lameness exam. I really liked this idea and think it is a smart option for me–especially as a new grad while I’m still developing clinical skills and figuring out my methods. One of the best lameness cases I saw was a septic hock. I aspirated ~20ml of purulent exudate from the joint. It was very interesting to see the difference in treatment of septic hocks between the horses we saw at the referral hospital at the beginning of the year and this cow.
One of the vets that works at Tarwin is the ‘down cow guru’. One day we got an after hours call for a dairy cow with a dislocated hip. Two other students and I went with the vet to see the cow. He showed us how to properly palpated the hip joint, the top of the femur (greater trochanter), and examine the abnormal appearance and movement of the of the leg in order to confirm that her hip had actually popped out of the joint. He also showed me how to roll a cow over by myself (for when I’m working alone). We then put a metal bar under the cow’s leg and attached her up to a tractor to help put traction on the leg and pull it back into place —its hard to describe the procedure (but its so cool and I love it)! The sun went down as we worked and I drove back in the dark —they told me to watch out for wombats on the road…I imagine hitting a wombat is similar to hitting a boulder…
The next week we had another call for a cow with a luxated hip, I was excited because I felt like I had a better idea of what was going on and could be more involved in her treatment this time around. She ended up being a weird case–firstly, she was still walking around when we arrived on farm. We gave her enough sedation to drop a huge bull but she still wouldn’t lay down! Then when we finally had her on the ground her knee felt swollen and we heard a loud pop when gently moving her leg. She may have had a partially luxated hip and also a knee problem.
During the last week we went to see a down cow and diagnosed her with compartment syndrome. We put hip clamps on her and used the tractor to pick her up and then completed a further exam. We tested reflexes, muscle tone, superficial, and deep pain. We diagnosed her with a radial nerve paralysis. The vet I was with then did some physiotherapy–>electrostimulation to assist her muscles in the healing process. While driving around with this vet I had some great discussions about acupuncture as a treatment for different conditions in animals.
I enjoy reproductive work in cattle and horses. Unfortunately, we only had one calving call during my placement. This was fun for me because the vet got me to stick my hand in first & diagnose the problem…. I felt 3 front legs…. and diagnosed her with twins! The vet untwisted and pulled the first one out and then left me to get the second twin out myself (which was pretty easy after she wasn’t entangled up with her sibling anymore)! We treated quite a few cows with retained fetal membranes, did some metri-checks, and saw one cow with a mummified fetus. Every day there was appointments booked for preg-checking. I actually quite enjoy this currently because preg-checking is something that is still quite difficult but I can see improvement in myself each time I practice. I received some great feedback from the vets on this placement about my preg-checking skills so that was encouraging!
Naturally, the call for a uterine prolapse came just after 5pm on a Friday evening. I’m sure I was much more excited about this than the vet (who probably just wanted to go home after a long week). The cow was up and walking around when we arrived, she went down again about half way through replacing her uterus. The vet, me, and the other student had quite the time spinning her around out of the squeeze so the vet could continue…and then of course she wanted to stand up again after that! We worked by the light of the quad and our phones until she was all put back together. We went back to the same farm a week later to do some other work, I asked the herd manager how the cow was doing–fantastic!!
I also really like wounds and trauma cases. We were called to see a heifer with a torn vulva after dystocia (difficult calving) that the vet spent a while suturing back together so she could hopefully have another calf.
We did a couple of abdominal surgeries in dairy cattle during my placement. Left displaced abomasums are a relatively common problem in dairy cattle. This is a condition that is usually seen not too long after a cow has a calf, starts producing milk, and eating a really high energy diet—> part of her stomach (the abomasum) is displaced to the incorrect location in her abdomen and fills up with gas. This makes the cow feel sick and she begins to produce a lot less milk. To fix this condition you have to cut into the abdomen of the cow and deflate the abomasum before pulling it back into the correct position. It was very interesting to put my arm inside of the cow and feel the abnormal abomasum while it was full of air, and then to feel it again after we had removed the air and pulled it into a normal location. I’m concerned that I’ll get called to see a really large dairy cow with this problem and I wont be able to reach her abomasum because my arms are too short!!! One of the other surgeries we completed was an exploratory laparotomy— one of the vets had felt a large mass inside the cow’s abdomen during a rectal exam. Once we cut into her abdomen we discovered that she likely had a large abscess on her kidney!
I got to participate in an awesome new herd health management technique that Tarwin is performing—teat sealing heifers. A teat sealant is a substance put into the teats of dairy cows after they are finished milking to prevent them from getting mastitis. The procedure is now being offered for heifers (cows who haven’t had a lactation yet) in herds who have a high percentage of mastitis in that group. I had no idea what I was in for when the vets and nurses were explaining the process to me but we donned our aprons and boots and hats and even duct taped our gloves on. They unloaded a specially made trailer and set up a whole table with ‘dirty hand wash’, ‘clean hand wash’, paper towel, and teat sealant. The farmer ran the heifers on to the trailer and then we loaded 6 or 7 of them on, cleaned the teats, put in the sealant, marked them with paint and then released them into the field. I loved how seamless the process was and would be interested in seeing results in regards to how much the mastitis rate decreased on farm.
Another day we went out and did some sedated calf de-hornings. I feel as though more and more people are moving towards this more welfare friendly option. We injected sedative into all the calves and waited until they fell asleep and then did cornual nerve blocks. After they took effect we burnt off the horn buds, gave each calf an anti-inflammatory/pain medication drug, and checked for supernumerary teats and removed those. This was really fun because I got to do some of the nerve blocks and removed the supernumerary teats! Also, seeing 40 sleeping calves all snoring at the same time is adorable.
I also really enjoy post mortem examinations–especially after my feedlot placement at the beginning of the year. As the vet and I drove to the call we discussed reasons for sudden death of a calf a few months old. Our top differential was black leg (failure or absence of Clostridial vaccination). The calf actually died due to a failed/bad castration. We found a huge amount of hemorrhage in the lower abdomen and legs and an infection tracking up from the prepuce.
Pink eye is a common condition in cattle, especially in areas with a lot of flies because they can transmit the disease. In severe cases a 3rd eyelid flap can be performed to protect the eye and help it heal. After watching the vet do a couple of them I started helping out as well. We also injected antibiotics into the eyelids.
There was also a horse vet working at Tarwin. I spent some time shadowing him as well. The first call we went out to was a very loved horse that had been fed bread and had choke (an obstructed esophagus). This seems like it would be a really emergent situation but its actually not that bad and horses can remain like this for a couple days while we treat them. You just have to nasogastric tube them and flush the obstruction a lot of times until it starts to break down and either goes forward into the stomach or backwards through the tube. We also went and did a gelding (male horse castration surgery) in the hot sun! No more of that pouring rain—I actually really lucked out with the weather for the rest of the week. The farmers probably wouldn’t agree, but I liked the sun. We drove out to to a pre-purchase exam on an older horse. This was something we practiced on my equine external rotation. We also had to put a foot cast on a couple different horses because of wounds they had.
I had an amazing time on this placement! With all the hands on practice, tutorials on abscesses, down cows, nursing strategies, calving management, and chats in the car–I learned so much! Staying at my friend’s parents’ house was also lovely; they had warm home cooked food for me each night and made me feel so at home.
Thank you to the Payettes and Tarwin Vet Group!
