There is using horns, tails etc to catch and pull vs use as handles to hold/restrain as you push, eg. shorn ewes; I was catching culls out of the mob and pushing them out through a one way gate into a trailer. Right hand on base of tail, left under sheep's chin, my knees and legs push into body of sheep to make controlled and safe progress sideways to the gate.
I am open to change if any of you could demonstrate a more efficient and safe friendly way of doing this I am open to it. Monkey see monkey do (monkey taught this as best method in vet school but times change, also monkey's own experience shows it works well).
Sometimes catching by the hind leg is the best option, the devil is in the detail, 48. does mention "lifting" and "dragging" it is a guide. Catching a stationary sheep in a corner stood in a group and restraining in situ while its mates move away is a very different thing to catching a running sheep.
The method you are using Me is the correct one - hand under chin, other hand somewhere at the back or flank. I think we all sometimes simply have to hold onto horns - it was the routine use of
dragging and catching sheep by their horns which I objected to.
The Defra booklet is attempting to stop behaviour such as lifting sheep by their fleece - this bruises the muscle underneath, as can be seen if the sheep are on the way to slaughter - the meat will be marked and of poorer quality. That must hurt as it would hurt any species. I have seen big hefty sheep lifted by a handful of fleece at the back, and a horn at the front - not kind.
Point 48 seems to be a guiding principle, but not a law, and is open to interpretation. I'm sure we all want to treat our livestock in a humane way.
One great way I have found for moving a recalcitrant sheep, instead of dragging it along by the horns, or anything else, is to turn it round and
push it, nose between your legs. They don't seem to resist then, and no-one gets hurt. The Fleecewife patented shoving a sheep method
Worth a try. It also reinforces passing motorists in their belief that strange practices take place in the countryside
