Which wormer next?

I am wondering which wormer to use next year.

Year before last, I used Equimax/Eraquell/Panacur Guard = Ivermectin, Praziquantel
Last year, Equest / Equest Pramox = Moxidectin, Praziquantel

Any suggestions?
 
It's not a problem to use the same wormers again this year. Dependant on when you last wormed for enysted and tape, you may still need to worm now.

Sorry, don't agree with this! My horse had a worm count done in mid-jan and is on a worming programme and has now got pinworm so keep worming regardless of worm count results, and you need to be aware that worm counts are only for specific worm types, you still need to worm for some.

Pinworm are an irritation but they are not a serious problem for your horse. They don't migrate through their tissues like proper horse worms do.

Many fully wormed horses still have pinworm, there is a plague of the things this year and they are hard to get rid of. No excuse for not doing your count though and trying to reduce doses. You v=can treat for them if you see them.

It does but it explains that if the worm count indicates worming not to be necessary every winter ONLY as a precaution you need to worm against tapeworm and encysted redworm, the rest of the year if the counts come back clear no worming necessary.

I wonder why pinworm are so prevalent this year?
 
Borderreiver I have a number of concerns that none of the lab people who do the worm counting that come on here have been able to clear up (I think someone from abbey comes on here too) My wormy research history is in sheep so not directly applicable but was initially looking at the use of fecpak and the effects of aggregation.

This has led to my concern. when implementing this method for sheep a whole dropping was taken as a sample, from which 3g was taken. How much is taken for the horse testing (I have looked but cannot find) The pot seems tiny. the owner is therefore sampling such a small amount of the faeces that I cannot see how an accurate count can be provided due to possible aggregation of eggs in the faeces which I believed does occur.

I have said in the past on here that it would be much better to put the whole dropping into a blender and take a sample from that.

I worry that testing such a small sample could be producing false negative results (obv of more concern than a false positive) and I dont necessarily believe that the decision not to treat should be taken on a single low epg but more on a longitudinal analysis, I also think the frequency of counts when people are starting out is most important.

It also, from reading posts on here, seems to cause a lot of confusion among people who already find worming confusing anyway! and another bugbear is the use of 'clear counts' implying that the horse is clear of worms.

I choose not to worm count, this is on the basis that I treat for encysteds and tape but poo pick our horses daily so normally treat only once in the summer grazing season with an ivermectin.

Although I say all this I certainly do not underestimate the threat of resistance. Where I am based we have an emminent (sp) parasitologist and I have been to several of his talks which make for interesting listening. Particularly from the point of view of not worming and then putting on fresh pasture etc which is still common place.

If you could allay my fears on the methodologies....are there studies you could point me to to show that such a small sample of the horse dropping will produce an accurate result? I do have access to most scientific papers, I have just never got round to searching them as not at all linked to current PhD!

thanks

Borderreiver Very interesting; thank you.

I agree with Ester's concerns, and I too have a question: what constitutes "nothing there"

I have asked several vets in the past, and have had answers from 50 to 300 count...

Thanks again!
 
georgie afaik (and from the sheepies!) the lowest they can measure down to is 1 egg seen under microscope is 50epg. (eggs per gram of faeces)

so if no eggs shown that equates to <50epg not 0.

sheepsies, I think recommend treatment if >300epg, the lab that border works for ;) states that 200-1200 is medium burden and needs treating. But as you can see so much depends on the sampling method.

am a little bit :s that the directions show on that website also show faeces being collected from pasture...... IMO it is much better to collect from yard/ clean pasture if you have any but can't see this being mentioned though only a small thing I just feel like these small things add up.
 
I always worm with a double dose wormer when tapeworm one is due. I have a worm count in Summer and winter, and would only worm if I was advised to.

As I don't blood test for tapeworm, I still worm for it then. I see no point in worm counting when I know I'm going to worm with a wormer that will also do tapeworm as well.

I've recently done my horses with Eqvalan Duo largely because Merial, who make it, have agreed to pay for the next worm count as part of their research into worming effectiveness.
 
Thanks for getting back :) I am often a bit of a thread killer on these ;)

I think probably where it most has its place is on bigger yards with larger groups of horses where you are much more likely to have a few horses who are the main contributors to contamination of the pasture and the majority do not require treatment at that time.

I don't worry on your behalf ;), I do worry about the number of threads that have been started in my time on here from people having sent faeces off and receive the results with no idea what they mean or what action to take and end up more confused than when they started. I hope that we are getting through that slowly with more information as it is being mentioned increasingly more in mags etc. Also that a number of people seem to preach fec as the ideal way (without really recognising its short comings) .... ie recommending fec in the middle of winter when encysteds are yet to be treated for and think that people dont always then get all the facts that enable them to make the best decision for there situation.

As I said previously though I do worry just as much about the threat of resistance too though we absolutely don't want anyone to be in the same situation as the farm in mexico and the sheep farms down here that ended up with triple resistance :( and know that the BVA are now advocating it which is great :) sorry I often waffle on on these critters :) Parasitology would have been my alternative choice PhD subject :D

patches you shouldnt use the double dose one all the time (pyrantel) because there is some resistance to it now, the eqvalan duo has praziquantel in it instead which doesnt have any resistance to it so best to use that one occasionally anyway :)
 
I don't use the same brand all the time but I only tend to chemical worm twice a year March/October when tapeworm worming is due. Last season I used Equimax, the year before I used Pramox.

I have worm counts done in Summer and Autumn and **touches wood** have had a <50epg result for all of the horses, so haven't wormed at all. If I got a positive result, I would use a regular wormer, not a double dose one.
 
ah thats good :)

just wanted to check you werent using strongid and/or pyratape all the time which are the double dose ones :) with a bit of resistance (note 'a bit' is my superb technically terminology on that one :D)
