The most important thing is the active ingredient, rather than the brand, and whether there is any local resistance to any particular one on your land/in your local area. The vet or other farmers may be able to advise. Then change to a different active ingredient each year.
Thanks for all the help and advice
I asked the local vet if they had individual doses but they didnt. They did give advice on what type of drench to give, though.
But today I asked a neighbouring farmer to give his opinion on my sheep, and he had some fluke drench there, and drenched them for me
Also gave me advice on getting them in better condition before going to the ram (it will be late this year but better late than never).
He is also going to help me sell my remaining 4 lambs which is such a relief as my grass is getting in short supply (long story).
So I'm feeling a lot happier tonight - so glad to have such a helpful neighbour!!
There are pluses in going later to the ram the main one being that you don't have to feed too much expensive fodder and corn before the grass comes ready for the ewes and lambs to eat. My neighbour doesn't put any rams in till at least mid november, lambing late april to may, aiming to get lambs fat off only grass, and lessen the reliance on bought in concentrate feeds.
I should have added that it would pay you to 'cultivate' that local farmer to help with supplying veterinary and concentrate feed needs for you as small quantities cost a forune.
||We farm this way but your lambs will be smaller because they are younger if you plan to sell them with the main crop. Ours grow on, not all with us although that ratio appears to be changing. It's a balancing act isn't it.|
