The lambing upset us too. The first time I saw it I was quite shocked. I think, with all the reaction there has been to it, it is very likely that the Hutchinsons would now call a vet sooner, and use more lube!
I would far sooner have films like this than have them all be Disneyfied, and therefore feel that we have to say our piece, and then support the makers. Otherwise no one will ever be brave enough to do something like this again.
I also felt that as the ewe was in the field behind the farmhouse that lube and/or soap should have been fetched. However, I do know how cream crackered a hill farmer can be on day 15 of a hard lambing, and having just caught the ewe, how impossible a mountain it would have seemed to then let her go, return to the house, come back, catch the ewe again...
There is also the issue of editing, and some of the lambing footage was in a further away field. I'm not sure I can remember exactly which bit was where, except I do think the dung-on-hand incident was at a distance from the farmhouse.
I'm not saying it's okay, but I am saying that it's understandable and that all of us sometimes don't quite do things as well as we would like.
On the cutting of the horn, sometimes it is necessary to cut into living tissue. Our vet has done it twice for us (when I farmed Swales.). Anaesthetic can be used but is of limited help. Tourniquet ditto. Cauterising can be used and is, in fact I saw a bullock's horn getting cauterised on The Yorkshire Vet recently.
I totally agree that breeds where major horn trimming is frequently needed should address horn growth angle in breeding programmes - but a) inevitably, one focuses on other aspects, and an outstanding tup with one close horn is probably still going to get used, b) it's not just genetics - how the lamb lay in utero can affect later horn growth, for instance.
In Blackies, they shape the horns in the tup lambs, to make them grow out more.
Finally, on antibiotics, it is far better to not use antibiotics were there is no infection. Moss to staunch bleeding and act as a natural antiseptic is a much better thing to use than the ubiquitous and overused blue spray.
