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.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

Please see our full Terms of Service and Privacy Policy for more information.

  • Am I doing this math right? Liq. Fenben.

    a 1000ml bottle would basically be a 'power pack' (double dose for 5 days) for FOUR horses, correct?


    And I think I just made my head explode... the 290gm tube would do... ??? One? I keep coming up with 1.2 and that doesn't seem right, but maybe it is.

    I love math.
    but you aren't giving enough info. . .

      Here are the details:

      10% fenbendazole
      4.6 mg/lb for 5 days power pak dose
      Figure 1000 lbs horse?

      I'd do the math, but I keep coming up off by a factor or 10, I think.


      • #4
        1000lb horse needs 46mL/day for 5 days, for a total of 230mL per horse.

        230mL * 4 horses is 920mL total. So yes, 1000mL covers them for 5 days.

        however, unless you are absolutely sure they are 1000lb, then you're going to be short, as I would do 50mL/horse/day, making it 1000mL total, and unless you can suck every bit of that 1000mL out of the bottle, well...

        And if the horses are bigger than 1000lb, you definitely need more.

        4.6mL per 100lb of body weight, and I round up to the nearest 5mL.

        If you're talking about paste, then it's the same conversion - 4.6gm per 100lb of horse.

          Actually they mostly come in around 900 or right at 1000lbs. I only do the big girl for 1200. (which, yes, complicates it, but I haven't gotten THAT far yet--I have one around 650/700# so the two added together come to two 1k# as far as ORDERING goes )

          The 290gm tube is paste, yes.

          Sooo.... it's the same math--grams/per 100lb as ml per 100lb? Um... that seems right--metrics and all (10% is 10% of one gram or one ml.... right??? )

          So the 290g tube would be ONE horse with one day (double dose) extra... ( 290/46... comes out to 6.3 .... )

          Two 1000ml bottles is too much by about 2 horses/full course... but 1 is short by about 2... Trying to figure out the best way to order. How long does the liquid stay good for? I wouldn't use it again for awhile... probably at least fall when the pg mare is weaned...

            Yep, it's the same math - 4.6mL or 4.6gm, liquid or paste, per 100lb body weight.

            Get as accurate with your weight as possible. Scale is best, obviously. But here's a link I thought I'd lost that gives a more accurate calculation than the one I usually give out

            And then, just for good measure, I'd still round up to the nearest 5mL/mg

            So, calculate the dosage for each horse individually, rounding up, and add

              two ideas that might help. Safe-Guard is the same chemical as Panacur and
              the liquid is the same concentration. You can buy Safe-Guard Goat Dewormer
              in a 125 ml size so if you need just a bit more than 1000 ml, getting one bottle
              of goat dewormer in addition might be your most economical approach.

              Other comment, you will need to have the "gun" to use the 290 gm size of
              Safe-Guard paste. It comes in a tube similar in size and dispensing as a
              caulk cartridge. The gun is similar to (but not identical to) a caulking gun.
              You do have to buy the gun as well as the paste cartridge, but the gun
              is fairly sturdy metal and you won't have to buy another the next time
              you want to use the large paste cartridge (unless you misplace the gun).

                Goat Wormers for Dummies

                I think my eyes just rolled into the back of my head trying to follow this Thread.

                Was just getting ready to post a question about the goat wormer & now I am even more lost.

                If I buy this bottle: http://www.tractorsupply.com/webapp/...g=true&cFlag=1 Is it enough to Powerpack 1 horse that weighs 900 pounds?

                  Seriously guys--PLEASE use the search function. I think poor JB has explained this every week for the last 6 weeks.

                  900 pounds divided by 100 = 9
                  9 x 4.6 mL = 41.4 mL per day
                  41.4mL x 5 days = 207 mL total for a PowerPac

                  So, as reflected by every other thread we've done on this same topic, you need TWO 125mL bottles to PowerPac any horse that's bigger than 543 pounds.

                    LOL, it's ok. I think

                    Theraputic dose of 10% fenbendazole (paste or solution, doesn't matter) is what you're looking at for a "power pack".

                    4.6mL per 100lb of body weight, per day, every day for 5 days. Liquid or paste, doesn't matter.

                      JN4JENNY, I DID read. As stated, I became more confused as I went along. Rather than make a mistake, I chose to ask. I will continue to ask questions, even in the face of your ridicule. Just put me on ignore, so I do not offend your brillance.

                        he,he... I started out knowing the DOSAGE, but was getting gummed up in the available forms and... well, face it, extended math.

                        I add 2 + 2 and get 22.

                        Not *quite* that bad, but when I start to do stuff sometimes, I might've had it right going in, but then I confuse MYSELF.

                        And THAT is why we have FRIENDS. Right JB?

                        Now, ask me about pH, calcium and odds of foaling... I'm SO THERE.

                        But THIS thread is about figuring out the most economical way to powerpack 7 horses. And economical doesn't *always* equal cheapest... i.e. if the liquid doesn't last--I'm being quite wasteful to get two 1000ml bottles when I could get one bottle plus two tubes.

                        (and yes, I know about the gun--as a one time cost I think it's probably worth it. I will most likely be doign this math at least every-other-year, if not yearly... the big tubes are SO much cheaper! Only beat by the liquid--but the liquid doesn't win if you've got the wrong # of horses and no one to 'share' with. )

                          I think 1000mL plus 125mL would be cheaper than 1000mL plus 2 tubes, unless you find the 2 tubes for cheaper than 125mL (obviously).

                          I haven't had to worry about leftovers, as my rounding up has me using a full 125mL per 2 horses each day, so my 5 125mL bottles is a full 5 day course.

                            I'm thinking the liquid is worth it just for convinence too. Mine eat it in beep/falf.

                            OH, and see, I screwed up the math AGAIN. SIX horses to do. #7 is actually 7 and 3/4 and will not be powerpacked but rather something else as she's due in 3 mos.
