Abattoirs pay
deadweight, so the testicles will have been removed before they make that measurement anyway
In the ring at the mart, selling
liveweight, the buyers will know the testicles don't fetch them any money so potentially will bid a little less per kilo overall
. However they will also know that entires are likely to be more lean than wethers, so that overall perhaps they pay the same
If you're having them killed for yourself, and like 'sweetbreads', then by all means keep them entire - but as with the liver, you will need to tell the abattoir / butcher you want them and go to fetch them a day or two after slaughter; the offal isn't hung for a few days like the body meat, and won't come back in the box from the butcher.
As to keeping ram lambs entire, the things to think about are:
- Can you keep all your ram lambs separate from the girls, from about August onwards? (Maybe earlier with Dorsets, Charollais and some others. I don't know about Shropshires.)
- Will they all be ready for slaughter before tupping time comes around? (The correct answers are either No or Maybe. Even if they should be ready, you may get one goes lame, or is strucken or has some other illness that means it can't be sent with the others - and you still have to be able to manage it until it is ready to go.)
- Given that you may have one or more around when you are tupping, do you have a group he/they can run with and a field safe to keep them in, away from the girls getting tupped and from the girls who are not to be tupped?
- Are your fences really good? Nothing sours friendly neighbourhood relations like a smallholder tup lamb getting with the commercials or pedigrees next door
In practise, most of us with primitives are happy to band when the testicles are big enough to band, even if this is a little over the week. If they get really large - which some of mine have, relatively speaking, because of course I can't catch them once they're 10 days old and wick as heck!
- then it's off to the vet or use burdizzos yourself. We use burdizzos on the calves, so BH is very experienced at that, but he's not keen on doing it on lambs (with the appropriate sized implement, I hasten to add!) so I'll be taking my flighty 4 to the vet in due course. Although they're crossbred, they probably won't be ready before autumn, and I don't want them tupping ours or our neighbours' sheep, nor being kept indoors, so I'll get them seen to.
