Hi everyone,
We have a recurring problem of certain lambs (particularly boys for some reason) going really squitty after weaning. It's not caused by worms or cocci and it goes on for months, so can't be due to fresh or wet grass.
One thing I haven't managed to rule out is cobalt / selenium deficiency, so I'm thinking of giving both our ewes and lambs boluses this year (probably 'smartrace (http://www.molevalleyfarmers.com/mvf/store/products/agrimin-247-smartrace-for-breeding-ewes-pack-of-50)' or similar) to see if that makes any difference.
So, before I do, can anybody tell me how to actually give a bolus? Is it just like giving a drench, or will I need the vet to show me how, the first time around?
Also, is there anything else I should be aware of before supplementing cobalt / selenium / idodine ?
Thanks in advance folks! :thumbsup:

Giving a bolus can definitely make a difference and I think for sheep that look like they are struggling its a great idea. We bolus the pedigrees, but don't bother with the commercials as the hybrid vigour in them means they don't need it.
To bolus you will need to buy a gun (these are usually metal and very basic). Then you pop each individual bolus into the gun, grab a ewe and place it from the side of the mouth. make sure you place above the tongue and right down the throat otherwise they will crunch it or spit it out.
It is very simple, and worthwhile if the ewes are struggling a bit. We do it before lambing and then the lamb benefits from the bolus as well as the ewe.

We have a cobalt deficiency on our land here so we bolus every 6 months. As above, it is pretty simple, especially if you are used to drenching etc. You will usually still get a couple that manage to spit them out! The bolus guns are pretty cheap, nothing special. I would go will something like smart trace too. I got cobalt only when I first bought but now wish I had got an smart trace

smart trace?
-
If you can get someone competent to show you how to do the first time then that would be beneficial, it's not always easy, depending on the size of your sheep. Also, vets see a lot of throat injuries due to people administering boluses badly.

Smartrace by Agrimin. I agree with Foobar about getting someone, preferably a vet, to show you how to do it. Sticking a small metal pipe deep into the roof of a sheep's mouth, especially if the sheep is struggling (and they really don't like it) can cause severe injury. Have you considered a mineral drench?
-
Thanks everybody,
The vet is due next month to take blood samples for MV testing, so I'll buy the stuff and ask them to show me whilst they're here.

Mineral drenches tend not to boost levels for long. We have used the Agrimin and they seem huge, we used a little lube on the bolus. Seemed to help it go down.

WOMBLE have a look at Carrs bolus ,its fairly small and you could buy at R & R Balloch . Bolusing is a lot harder than dosing , holding the sheep still is vital and not pushing , a little twisting since the gun is normally bent and it should gently slip down
-
Thanks Shep, there's a Carrs shop at Stirling Mart, so I'll check that out :thumbsup: .

OK, so I got the vet to show me, and then I tried it myself a few times. I was really surprised how far you have to put the gun in - it's definitely harder than drenching! Also it seems there would be more risk of injuring the sheep if it were to jump at the wrong moment.
Apparently sheep have a sort of hump / bump at the back of their tongues. That sort of makes a 'point of no return', so if you can get the bolus over that, it gets swallowed down ok. Actually, you can really feel the gun stopping at that 'hump', and then suddenly you get it right, and over it goes!
Thanks for all your help folks! :thumbsup:
