Cull The Ewe

Just�as we closed the doors to the clinic and�finished up�our Saturday morning consults, the afterhours emergency phone rang and I had to go treat a horse with a huge flesh wound. It was the sweetest horse and he cooperated so well with the whole process. As I was ready to leave the property, the farmers casually asked me to have a quick look at this ewe. It is so funny how predictable farmers can be. They always have a few other cases lined up for us to have a ‘quick’ look at.

I personally find most farmers to be very genuine people and will happily give in to their requests.

There I was staring at a mob of ewes�from a distance and the owner kept pointing out one of them to me. She said that the ewe�had developed a very large swelling under her abdomen but�was still eating and drinking well. As far as she could recall, the lump had been�there for many months and had not changed in size. The ewe�had not recently lambed�and was not in lamb (pregnant).

She was wondering what the lump could be. The mob of ewes�were pretty skiddish�and that made it very difficult for me to have a close look at that particular ewe. When I suggested catching the ewe�for a closer quick look, the farmer burst out laughing. She said it was impossible for us to catch the ewe�at this very moment and it would take a few hours to organise that! I definitely established she was a healthy ewe with a very large swelling under her abdomen.

My first thought was: she must have a hernia!

I took pictures of the ewe�and explained the only way to confirm the diagnosis would be a proper examination and hernias�would require surgical repair. The other possibility was an abscess (lump full of pus) but I would have expected the ewe�to be very sick by now. Then the farmer asked if I recommend culling this ewe. I stuttered and replied: ‘There is no need to rush to the decision of culling the ewe. She has had the lump for several months and is bright and happy. Leave it with me, I will contact my mate from Norway who regularly treats sheep and get her second opinion on the photos�and get back to ya!’.

I followed through with my promise and emailed my mate the pictures of the ewe�and history and asked for her second opinion.

In Norway, every sheep is considered very valuable and farmers will readily seek veterinary attention if any of their sheep are ill.

Unfortunately�that does not apply to Australian sheep farmers because they run heaps of sheep on�massive properties and unless they are losing sheep in the dozen, they would never call out a vet. This is a generalisation and so does not apply to every Australian farmer.

I was secretly hoping my friend from Norway will offer me all the solutions to my ewe�dilemma. She promptly replied supporting my suspicion of hernia in this ewe. She said the herniation is probably due to a�ruptured ligament leading to intestines/organs poking through and just being held in place by skin. In Norway, they call it “vom�i�skinn” = “rumen in skin”. Heavily pregnant ewes�or ones that have recently lambed�seemed�predisposed to�developing hernias in Norway.

She, did however,�think�the location of the�herniation in this ewe�was particularly�odd. They usually�herniate�to�either side of the ewe’s abdomen not below its midline.

Again she could not rule it out�the possibility of the lump being�an abscess. To my utter dismay, she then proceeded to explain they usually recommend culling these ewes�as it is not cost-effective to treat them! I was simply shattered to hear the news because Norwegian vets usually get to do c-sections on ewes and all kinds of procedures to save them but this was not one of them!

I picked up the phone and called the farmer and explained that even in Norway, they would recommend culling this ewe�if she was confirmed to have a hernia. I was well aware the farmer was not keen on doing much workup for this ewe�but pressed on with discussing all the options. I told her it is important for us to examine the ewe�to determine if it is an abscess or hernia or possibly even a tumour and only then can I give her my appropriate recommendations.

Sue, the farmer, picked up on my very disheartened vibe and out of nowhere said:

‘You sound very passionate�and keen to give this ewe�a good go, would you like to operate on her to see if you can save her so long as the procedure is pro bono�(i.e. no charge to her) and no strings attached if it doesn’t survive?

She was well aware of the risks and simply happy to give me a crack at trying to save this ewe. I was instantly filled with excitement and said:’Yes I would love to take you up on this great offer!.

Judgement day arrived. Sue dropped off the ewe�and wished me luck with the procedure. We proceeded with putting the ewe�under full anaesthetic. Check out the pictures below.

It was a pretty spectacular ventral abdominal lump and it felt hard and I was not really able�to reduce it (push it back) to confirm it was a hernia. I then stuck a needle in it and got some pus and that was indicating�the lump was an abscess.

It was still very confusing at that stage and we were quite unsure about what we were dealing with.

Finally I cut into the lump and voila, I saw intestines and confirmed it was a hernia.

What followed was a very tedious job of trying to repair the abdominal wall.

I had to drag Alana, one of my colleagues, into surgery to assist me in putting this together. It was one of the most difficult and exhausting surgeries I have ever performed and I could see why the Norwegian vets considered it not viable to routinely do.

It took us a total of four hours to suture the linea�alba back together and replace the abdominal content in their correct position.

Needless to say, Alana and I made the best out of a pickle of a situation. I promised Alana never to drag her into my future probono surgeries…

Just�as we were recovering the patient, one of my bosses passed through and said: ‘Wow it still looks�like a hernia�even after you have repaired it’.

Let us just say my boss was lucky�to be my boss because if he wasn’t, I may have strangled him at that particular moment in time.

He was�right in the fact that there was still obvious swelling there but nothing like before�and the intestines were back were they belonged (in the abdomen).

I was so happy that my ewe�survived the four hours of surgery and recovered so well from her anaesthetic.

I�called the owner to tell her the great news and she was baffled. She had not expected to pick up the ewe�as she suspected she would not survive the procedure. She drove in to pick her up and was so touched by how I kept referring to the ewe as ‘Possum’.�The�ewe�was by no means considered a pet by this owner. However, Sue decided to name her ‘Possum’ as a thank you for my hardwork. We thoroughly discussed the post operative care and I strongly emphasized the importance of not�breeding from this�ewe as she will most definitely herniate again.�’Possum’ recovered really well and the owner kept me posted on her progress over the next couple of weeks.

A few months later, I kept getting messages from Sue demanding I call her back URGENTLY.

My heart was beating really fast when I finally got a chance to return her call. As soon as she heard my voice, she said: ‘Rayya, guess what?’�Possum had the most beautiful little lamb?’�’Possum�must have been�in early pregnancy when she had undergone the�massive surgery.�’Possum’ had defeated all the odds, survived massive surgery, hung on to her pregnancy and given�birth to the healthiest and most adorable looking lamb.

Sue kept saying that Possum’s lamb�was�bigger and healthier than all the other ones in the mob. She was absolutely thrilled and told me she named the lamb after me. The price of this precious lamb was the evaporation of all my efforts to repair the hernia. Possum had re-herniated post-lambing.��Her lamb had consequently learnt�to suckle from� an�abnormally positioned�udder which was�pushed backwards by the hernia.

Moral of the story, I won’t be operating on possum again, that’s for sure!

I just feel�so privileged to have been involved in indirectly�saving two lives not just one-a ewe & her unborn lamb!

Rayya The Vet

I was born overseas and grew up in Lebanon. About 9 years ago, I left my family and friends behind to pursue my dream of becoming a veterinarian in Australia.

I have now been out in practice for the past 5 years. I absolutely love being involved with all types of animals and consider it my "calling". Whilst my job can be quite an emotional rollercoaster ride, I cannot fathom doing anything else for as long as I am living. I simply feel blessed every day that I am practicing what I truly love.
