As the title really, I’ve held off worming for encysted red worm this year as we’ve only had 2 hard frosts, the weathers been too wet and mild-ish, south west based.
I’m curious what everyone else is doing / done, how long can I leave it if we don’t get cold weather? Thanks :-)

Depending whereabouts, possibly might NEVER have any prolonged frost - so just make sure you pick up all the droppings, whenever!

Worm before or after the cold spell?! That's always confused me

You need a few days of cold temperatures first apparently. I'm targeting Sunday because I know I can clear the field Sun / Mon.

Last year I just kept waiting and it was so warm in Jan I ended up clipping out my native who was sweating just in the field.

Westgate have told me to worm now as we are higher risk according to their new flow chart (and we had positive in autumn)

Is that your horses which are higher risk or in general? I've been surprised at how many are positive on the encysted redworm blood test. I'm not going to have that done but the ones I do know were clear FEC too.

Ah that's good to know, thank you. Our fields are cross grazed by the sheep before and after the horses have been in them, so whilst I don't poo pick that massive space, i do have worm hoovers! FECs are all clear, but do encysted as a matter of course
 
For interest I blood-tested my 15yr old DWB in November and he had a very high encysted count so he was wormed at beginning of December with Equest. He’d had low/ no eggs seen on count, no tape and has been wormed every year with Equest Pramox. My other horse a 6yr old had a very low reading and negative for tape so won’t need additional worming. I did this for a yard move as also needed strangles test done plus the young horse colicked after Equest Pramox given early February so wanted to avoid or adjust worming if possible. .

Well, there is resistance being increasingly reported against moxidectin (the anti-redworm ingredient in both Equest and Equest Pramox), and like most reported resistances, will depend on where you are, where your horse has been living, and the resistance statuses of worms in those locations.
Moxidectin is extremely powerful, active lengthily within the gut, has been associated with adverse reactions (especially when twinned with praziquantel in the Pramox version), and if it’s not even working for your horse - probably time to look at another product.
We won’t touch moxidectin because of risky side effects, and use Panacur Guard against encysted - which - bloods & FECs and probably a lucky location - have shown routinely negative. Hurray!

Thanks for the info I’ll probably get him blood-tested again and see if there has been any change. He did happily chomp 🤮 a mares poo at the yard I’ve just left (second move this year due to my long-term yard closing and then not working out at first place we moved to) and she’d been a neglect case and still had a high worm burden unfortunately the first vet hadn’t made it clear which wormer she needed so it was still high encysted when he was with her. I’m not sure if it had any bearing on his reading.

Probably won’t have helped - horses! Can be so fussy with really expensive feedstuffs, and - then!
Good luck

I also do 5th November and beginning of March
 
I did tapeworm end Nov and will do encrysted with moxidectin late Jan/Feb.

My learning was that you need to do it while the encrysted are still dormant due to cold weather so really there should be plenty of time but I'm not actually sure what 'cold' means!

Does anyone know if there are guidelines as to who is likely to be resistant to Equine Guard? Is it geographical? I last read that there was 60% resistance so seems little point in risking it.
 
I think I'm going to blood test when I get back from holiday mid Feb I think as I need the vet for other routine stuff and as we've got a colic history now I'm Uber cautious.

High risk due to number of horses grazing and cross grazing (at livery) not an ideal situation but it is what it is. So sticking to their advice and worming if they tell me to!
