I bought a massive bottle of Triclabenzadole too - with all the fluke about, suppliers had 'mysteriously' sold out of anything smaller. Hmmmm.

I have found these people good to deal with http://www.hyperdrug.co.uk/  They seem to cater for the smallholder.
 
Regarding unused ivomec/oramec it is great for the chickens cures scaly leg and most internal and external parasites all in one go.

By the way we woke up to our first lambs today, twins one pure black and one pure white.  Out of Jacob x Texel ewe and Southdown tup. It was her first lambs so she did very well hid under some trees out of the snow.

I use hyperdrug all the time, they seem pretty competitive.

I've not seen any proof at all that triclabendazole doesn't work just as well when the liver is damaged. Heard it said a lot, but not seen any actual evidence.

Well, horse's mouth, then. 

Which said, we have certainly had a batch in which the fluke was not cleared up by dosing with Combinex - and I'm sure we don't underdose, quite the reverse. 

This year we've fluked all summer and wormed through the first half of the winter - the weather simply didn't change enough for either parasite group to get inactive, and we had lab reports showing fluke damage in lambs sluaghtered in August 

Wow to the 600 and only 2 in lamb. Did he have fluke? It can be one of the causes of low scanning rates.

We have assumed it's fluke, having heard of other very poor scans where it has been fluke.
