Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

Which wormer now...?

  • Which wormer now...?

    So, my gelding needs to be wormed again beginning of May. For a long time he was just on ivermectin, then back in Jan I gave strongid double dose, then in March quest plus. I didn't see much difference with the Strongid, but a HUGE difference after the Quest plus. No idea if it was bc of tapeworm or bc of strongyles, although he was getting the prazi 2X yearly before as well in the ivermectin, so I am thinking probably the stronglyes.

    This leads me to want to powerpak. Should I do an ivermectin in the rotation again and wait another 4 weeks to powerpak, or should I go ahead and do the powerpak without worrying about the ivermectin? I want to get rid of everything in a safe manner... and I've heard that you can do powerpak at any time regardless of where you are in the rotation, and also that you should do ivermectin at least every other time that you worm.

    So.... what next? Thanks for the advice

    Since you gave moxidectin, even if you gave it March 1, you wouldn't want to do anything else until June 1 - 12 weeks for moxidectin.

    You saw a difference after the Quest because you killed encysted strongyles - same as a Power Pack, except moxidectin doesn't get the EL3 stage.

    Strongid (pyrantel pamoate) has a high enough resistance that it's almost useless as a single-dose product now. SAme with fenbendazole. But the double dose of strongid got your tapeworms, just not a whole lot else. The Quest cleaned him out but good.

    So, June 1 you could go back to a regular ivermectin.

      JB - Are you saying that there is no need to worm with ANYTHING for 3 months after Quest? I rotate my de-wormers every 6-8 weeks. Should I push back my rotation after administering Quest products?

      Thanks.

        Yes, that's what I'm saying. Every 6-8 weeks is not a valid rotational schedule. You typically don't do anything after ivermectin for 8 weeks; moxidectin for 12 weeks. Single doses of pyrantel pamoate and fenbendazole are almost useless in a normal rotation now due to high resistance, so you don't normally use them at all ( in single doses) but if you do, for some reason, then you'd wait 4-6 weeks after that to use something else.

        It's all about the ERP - egg reappearance period - which is different for each chemical.

          Great info, JB. Thanks. I use a 6-8 rotational schedule that my vet distributes. But, I've always had a feeling that his recommendations are outdated.

          You're in NC, also. Do you have a "set" rotation that you use? I'd love that info, if you don't mind sharing.

            Ahhh yes, the "vet rotation". Most vets are very, very outdated when it comes to dewormers, unfortunately. Maybe you can suggest kindly that your vet watch The Horse's deworming webinar

            You're in NC, also. Do you have a "set" rotation that you use? I'd love
            that info, if you don't mind sharing.
            Well, it sort of goes roughly like this:

            late Winter/early Spring do a Power Pack
            2 weeks later 1.5x anthelcide
            8 weeks later ivermecin
            8 weeks later double pyrantel pamoate
            8 weeks later ivermectin
            8 weeks later ivermectin
            8 weeks later ivermectin+praziquantel (I only use Equimax)

            I think I got all the rotations. I took part of this, mainly the anthelcide dose, from EqTrainer's program. Note that it's not a single dose of anthelcide, which is pretty ineffective these days (oxibendazole). The 1.5x dose is still effective against strongyloides.

            I swap out one ivermectin rotation for just a tapeworm rotation, so I can lay off constantly using ivermectin.

            Now, if we have a hot dry July/August, and one of those ivermecs falls in there, I'll usually skip it - the environment is just not very conducive to egg/parasite survival in the pasture, which gets dragged regularly in the Summer to expose things to the sun and heat. But if it's a wet(er) Summer, I'll keep on going.

            At the end of this year, I'll have another FEC run to make sure things are still clean, and if so, I will likely not be so frequent with the ivermectin next year, and will check FECs about twice in the year to make sure that's still ok.

              I realize moxi lasts 82 days - but I have to worm May 15. Basically, my barn is on a set worming schedule, you can either do it yourself or pay the BO to do it, but all the horses HAVE to get wormed on the same day. She only uses ivermectin with the praziquantel combo 2x yearly, and after discussing with the vet/chiro back in Jan. I started rotating myself. So, the BO gave ivermectin single dose in January (honestly he probably has a huge wormload because I'd been on her program of single dose ivermectin for about a year and a half, and he's a huge horse so I'm betting he wasn't even getting enough. Didn't realize she was only giving 1 tube and assuming he was under 1250...). I gave the strongid double in mid-feb, then in mid-March gave the moxi+prazi combo, because my vet said that the only things that work for more than 4 weeks really are moxi and ivermectin. So, I have to worm him on May 15 - the BO is really strict about this date to control worms on the property.

              So, knowing I have to hit him with *something,* should it be the ivermectin double, an ivermectin single to minimize stress on his system and then do the powerpac when the moxi date is up in June, or should I go ahead and do the powerpac?

              Of course, I could try to fib and just use a syringe of applesauce. Doesn't sit quite right, but if it would be really damaging to the horse to worm again, I'm not above it...

                And to JB - I really think the Quest did it too. I used the strongid first to clean him out a little, but the quest did a great job.

                I am pretty sure it was strongyles because he's had praziquantel for the tapes 2x yearly (although it's possible at 1 dose he wasn't getting enough). I'm really itching to powerpac now because I know it'll get the L3 that the moxi left if he's got a big wormload, and I can't wait to see him bloom out after that.

                Basically I need someone to tell me if I need to be patient (not my strong suit) or if I can go ahead I am betting I probably need to be patient, but I am hoping that someone with a little more experience with this rotation stuff will say that powerpacs can be done at any time... it's kindof like Christmas Eve for me to see the changes in this horse! It's so hard to wait when I know something will help him...

                  Deworming is all new. Research has shown that 95% of he wrorms are resistant to fenbendazole and other "zole" dewormers. 50% of the worms are resistant to strongid. The only way to tell is to run a quantitive fecal, deworm with that product, and then run another quantitive fecal to see the difference (what % is killed), so you can know the effectiveness on your worm population. If a drug is not effective on your farm, using it is just throwing money down the drain.

                  New guidelines recommend using different worming programs on different horses, depending on their natural, genetic worm immunity.

                  You should really take the time to watch this video webinar "Deworming your horse". http://www.thehorse.com/Video.aspx?vID=183

                    evans36, don't take this the wrong way, but it's time to stand up and educate your BO on parasite control issues Do watch that webinar - it's awesome, and has the most up to date information on what chemicals are still effective and which are not, the dangers of potentially causing or increasing resistance by simple deworming according to "well, it's been 8 weeks, time to use something again."

                    It's not a matter of just sticking a tube in their mouth on the 15th of every other month. That is part of why we're in such trouble now

                    So no, I would not deworm with anything in May. Seriously.

                      Webinar

                      Thanks for the heads up about the Webinar on THE HORSE website. I've seen links to it, but I assumed it might be biased because of their sponsors. I'm glad to hear that the info is good. I'll try to check out the next one.

                        Thanks for the advice. Apparently the vet that the BO has used forever has told her that ivermectin every 8 weeks and prazi 2x yearly is fully sufficient for the animals on her farm. She's very low-maintenance, horses-be-horses, and a bit old-fashioned. Love her and she knows a hell of a lot, but she's been stubborn about the "my horse, my worming schedule" thing. Especially because the vet backed her up who knows when. I love the barn and my horse is really happy there, but it is definitely somewhat frustrating when the worming schedules and feeding practices are concerned.

                        It's a conversation we've had before and she "won" because otherwise I'd have had to move the pony. But I will just try again I reckon and see. And if she says no, I will just use applesauce.

                        My horse hates it, so he'll play along and spit it out just like wormer

                            Send her a link, AND her vet. Tell them these are NEW guidelines, that replace the 40 year old "recipe" for controlling worms. It is EXCELLENT, and and I am ALWAYS a sceptic. No one is more old fashion than I am unless something really makes a lot of sense.
