We have the vet to castrate the odd bullock when for some reason we haven't burdizzoed or ringed. It's so quick, and the knife is so sharp, you never ever see any sign that the bullock has noticed.
I'm not sure about doing it myself to lambs though - the scalpel bit would be ok, it's the making sure you have all the cords and don't get a bleed
. I may ask the vet about it though.
Yes we'd be worried about flies on the wound too - on cattle you might use Swish or something to keep the flies away, I guess you could do something similar with the tup lambs.
And I really
really don't want to ask this (picture ostrich with head in sand)... but I have to. What and where is the evidence on the downside of ringing? I have always based my understanding on my own experience of having a haemmerhoid banded - gosh I didn't like it, and felt very sorry for myself for maybe 24 hours, but after that, no problem. And after doing many hundreds of lambs, I am very comfortable now with my technique and find that generally the lambs either don't react much at all, or walk a bit stiff-legged for a few minutes, or very occasionally thrash about and cry for up to 10 minutes. When I first started doing it, I got a lot more of the thrashing about type, to the extent that I would make sure I had the lambs and ewe somewhere safe where the lamb wouldn't be endangered if it couldn't get up and run with mum for 10-20 minutes. (And no, I wasn't snagging the testicles - but I think when you are new to it, you probably faffle on more and maybe cause more bruising; when you are very practised it's nearly always very swift and sure.)
