Animal welfare sheep shearing wounds | Department of Primary Industries and Regional Development


My name’s David Wrighton and I am a Veterinarian
officer in the department of Primary industries from Regional Development
working in the animal welfare policy division. What I wanted to demonstrate to you
today is the correct method of suturing quite significant shearing wounds. So
we’ve got a deceased sheep and we are just explaining a common areas for the
areas where sharing wounds can actually occur. They can occur under the armpit under
the areas of the abdomen the pizzle area and also in the hamstrings as well as the neck. We’ve opened the area up to reveal the underlying what we call fat. We haven’t entered the muscle layer at this present time. we’re going to now
clean that wound and using an antiseptic solution now this can be in the form of
a registered antiseptic or it can be simply used with salt water
and that’s like a tablespoon of salt to a point or a liter of warm water mix it
together that acts is a good antiseptic spray that wound to clean it and our
hands are dirty as well so ideally we should be as well spraying our hands. The needle and thread should be in forms
of methylated spirit so anything like a little small container be given to you
with it at least that makes it a clean stitching technique as possible. Take the
first layer of skin on the side put through the needle which is the shearers
needle or S-shaped needle also known as a post mortem needle with the thread
which is going to be an extra strong cotton and you’ll see at the end of that
thread we also have a knot already placed enabling the suture mid to will
not to run through the skin. Place through the first layer of skin and the
second layer of the skin and we’re going to bring the two edges together and then
simply do a one single throw bring it together and then do another throw bring it together and finally a third
throw and bring it together. That area is now tight for us to continue the procedure. So we’re going to cut that last obsolete section of cotton material and continue it the actual suturing method. The important factor is not to go
too wide if you go too wide it’ll lose the strength of the suture itself and
you’re more likely to get wound breakdown, you should only be taking it
only around about two maximum of three centimeters away from your original
suture otherwise the strength of that stitching will not be as strong. Take the needle go again grab the other end of the skin. pop it through repeat the process again. The procedure will take slightly longer
than you might have deem necessary but it will ensure the strength of the wound with this form of running stitch make sure those two edges are coming
together neatly and we’re not pulling too tight we’re
pulling reasonably tight just enough for that you shouldn’t get it to come up
bulging otherwise you’re going to be causing more inflammation. So we put in this this is the final one putting it through. and this time instead of pulling
tight we’re going to allow a little bit of looseness in that final loop the
reason why are we going to be doing that is to allow us to do that final knot and
that final knot is going to be the important one, so we go left over right
warming a little throw pull tight. Left over right again pull tight and a final
one as well and finally once we finish that knot we take the scissors and cut. This procedure at the moment is done without any pain relief we’re hoping
that the product will be utilized at the same time as you spray the antiseptic
that will contain pain relief and that you will finish the sharing of the sheep first before finalizing the actual stitching method. Once we finish this
layer of suturing and the wound is now clean, it’s important that we disinfect
that area using a form of antiseptic spray and we’ve got one here an
antiseptic spray we just cover that area – obviously prevent any potential
bacterial infection we could also use a fly repellent around that area or
combination to prevent anything any fly strike. The animal should also be
effectively marked clearly in order to monitor the healing process of the wound itself.
