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 termI 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
I wont be doing it, because I agree with @CopperBeech that we need to keep it for as long as possible.
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.If you use zolvix leave them inside for 24-48 hours so anything that survives doesn't go back into pasture.
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.
Both these approaches make some sense, and I am unsure.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
appreciate that but info made sense applied alongside FEC after initial nemo drench .Stop asking drug companies for worming advice. If you take nothing else from this thread!
By 'combi drench' you mean Startect?@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 .
