Heptavac injector
« on: May 25, 2012, 11:01:38 pm »
 A few months ago, when  buying Heptavac at the local agri. store (very well known), I was persuaded to also buy the Heptavac injector.  I did not like the idea of using the same needle on all the sheep but could see the advantages of using a multiple injector.  I used it on the ewes successfully pre-lambing, and cleaned it thoroughly.
 Today I have tried to use it again for the lambs but the liquid is trickling down the outside of the tube below the 'gun'.  In the end I gave up and went back to individual jabs - but I have wasted 5 doses out of 25.  Has anyone else any experience of these multiple injectors please?

We have just a plasticky little gun thing and change the needle between each jab. I get the cheap one and get a new one every year as they don't seem to have any endurance.
We do the best we can with the information we have

I used Heptavac-P on the moorland farm, where we were injecting 530-ish ewes each year, 60-ish of them twice, and never had any problem.

It sounds as though the needle is not quite properly seated in the seal?  Or maybe a split in the tube?
