We have never used it.

Would it be a good dose to give lambs at weaning (end of July)?

Lambs are looking well after their rycoben (white) drench in May, will be getting a yellow drench at shearing. Always find weaning is a crucial one though.

I went to a meeting a few weeks back about worming, and I said that we only use zolvix for quarantine, but I was told to use it once a year for lambs when the burden is high :scratchhead:

I wont be doing it, because I agree with @CopperBeech that we need to keep it for as long as possible.

I only use it for quarantine dosing too. The Zolvix marketing machine appear be the only ones recommending it's use as an annual 'clear out' drench. Unless you have resistance to all the other wormer groups, I'd avoid it's use as a routine drench, if only because of the cost.

We have resistance to most wormers here so will be using zolvix once at weaning as per vets advice. We did one lot with it last year which weren't thriving and half were finished in three weeks after (but we also gave them cobalt and selenium). I don't know what did the trick but you could see them putting on weight in front of your eyes.

We use it in this instance purely as at that stage you are killing mass nos of worms efficiently,we have resistance to BZ and slight Levamisole by using Zolvix then I am protecting the status of my other wormers,leave it till all the others are completely ineffective then I am more reliant on Zolvix.This would mean more cost and more likely to gain faster resistance because I was using it more so I am trying to long more kinda long term

If you use zolvix leave them inside for 24-48 hours so anything that survives doesn't go back into pasture.
Doesn't work like that - anything not killed will still be producing eggs after 48 hours - and will continue to do so unless treated with an effective product.

Both these approaches make some sense, and I am unsure.
My inclination is to keep it as the "nuclear option".

I really really really really worry about the promotion of Zolvix in summer. The theory is that when the weather is warm and drier then the majority of the worms will be in the sheep and you can somehow magically kill them off with the marvellous orange medicine. Using the product at this time puts a lot of selection pressure on the population - there are few other worms to dilute any remaining resistant worms. Really worry about this as a concept. It is very much less safe than using it as a quarantine drench alongside a group 3.

Follow SCOPS principals to the letter and you are unlikely to find an increase in resistance. The initial SCOPS trial farms have no increase in detectable resistance over 10 years later.

was told yesterday at sheep south by zoetis to use a different class for each worming , maybe use a combi drench occasionally (startect ) avoid levamisole (yellow) late summer / autumn due to effectiveness against haemonchus,
do ewes at lambing with cydectin 2% injectable (100 days cover) as will hoover up some lamb worm issues (no good for lambs as it dosent cover nemo ) ,

@bovine would you consider using the combi drenches instead of zolvix instead as a quarantine . keeping that in reserve for later
By 'combi drench' you mean Startect?

If so then that is fine. I do worry about people being advised to use them at other times. We have the first reports of monepantel (Zolvix active ingredient) just over 5 years since launch. Worrying.

yes startect , I assume at some point there will be others available as i believe the NZ farmers think we are mad using straight wormers which make resistance happen more quickly , but its licence issues thats holding euro usage up .
seems funny resistance to zolvix already as too expensive to use as a routine treatment .

IIRC the Kiwi combo drenches are generally a mix of the actives we use normally, rather than any of the new groups. Startect is a combo of a new wormer and ivermectin, which 'should' help to delay resistance developing to it.

I believe the zolvix resistance was identified in a flock that was having to use it routinely, having had resistance to the other groups already. Just shows how quickly resistance can develop.:(
