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.

  • MSM and Ulcers

    Hi All, Does anyone have any experience with MSM, over a long period of time, aggravating ulcers in horses? Thanks, fg

  • #2
    On the contrary, it is said to alleviate - if not completely clear up - ulcers.


    • #3
      I've read that MSM is pretty effective complimentary treatment for ulcers.


      • #4
        Yes, my ulcer horse is on 10,000 mg of MSM daily.


        • #5
          My horse has been on 10,000mg daily of MSM since July, and developed ulcers this fall after being treated with bute for 3 weeks. I believe, however, that he had ulcers before I bought him in April (based on reports of his behavior with previous owners), and while the MSM was probably helping, I suspect they were restarted or exacerbated by the bute. Fortunately he's better now!


          • #6
            I haven't seen any ulcer symptoms in my horse since I started giving MSM, but in the last 3(?) months that she's been getting it I've purchased two different types of MSM. Both said to give it with or after feeding.


            • #7
              I had two vets - from 2 different clinics - tell me that MSM was fine, but to stay away from Glucosamine products.


              • #8
                My one horse has been on MSM continuously for over 3 years now and no ill-effects noticed so far.


                • #9
                  I had two vets - from 2 different clinics - tell me that MSM was fine, but to stay away from Glucosamine products.

                  Mallard: Did the vets have any opinions on chondroitin? I've worried about glucosamine.

                    Thanks, everyone! fg

                      No...I didn't ask about the chondrointin.
                      My guy is older and a getting a bit stiff and I wanted 'something' to help him out.
                      Both vets said to stay clear of Cosequin/CortaFlx, but that MSM was fine.


                      • #12
                        My horse recently started pooping more formed poop.
                        He was mushy for 8 months. Unless on slippery elm which helps ulcers.

                        But I took him off
                        Cytl M
                        and his soy product diet balancers

                        and he's had 6 months off due to injury. Which I bet is what healed his tummy!

                        Maybe the soy and Cytl M didn't help our situation?
                        Horses are amazing athletes and make no mistake -- they are the stars of the show!


                        • #13
                          I read the results of one study that suspected MSM of contributing to ulcers.
                          I can't quite remember where, it was in a horse magazine not too long ago, either The Horse or Equus, I think.

                          I have never read anything about MSM helping ulcers, but have read about it supposedly helping with most everything else, a miracle substance.

                            Why stay away from Glucosamine?
                            Just for horses with ulcers, or for any horses?

                            It's so hard to keep up with what's 'good' and what's 'bad'!

                              mallard- i'm wondering about this gluc. thing , too. did the vets say *why* gluc. is not good? sooooooooooooo many horses are on daily supps containing gluc.!


                              • #16
                                I *THINK* that some glucosamine comes from shark cartilage which has been shown to increase bleeding. So horses that are probe to ulcers are not supposed to take supps that come from that source. But there are other sources that are okay. Depends on the source if IRC.

                                this is from here

                                Date updated: March 08, 2007
                                Natural Standard Research Collaboration

                                Since glucosamine can be made from the shells of shrimp, crab, and other shellfish, people with shellfish allergy or iodine hypersensitivity may have an allergic reaction to glucosamine products. A serious hypersensitivity reaction including throat swelling has been reported with glucosamine sulfate. A small pilot study of six patients with known systemic reaction to shellfish, showed no reaction when challenged with glucosamine.
                                There are reported cases suggesting a link between glucosamine/chondroitin products and asthma exacerbations.
                                Side Effects and Warnings
                                In most human studies, glucosamine sulfate at a dose of 500 milligrams three times daily (tablets or capsules) has been well tolerated for 30 to 90 days. In a three-year study and several short-term trials, the number of adverse events in patients taking glucosamine was no different from placebo (sugar pill). There have been reports that in laboratory animals, doses as high as 5000 milligrams per kilogram taken by mouth, 3000 milligrams per kilogram injected into muscle, and 1500 milligrams per kilogram through the veins have not caused death.
                                Side effects may include upset stomach, drowsiness, insomnia, headache, skin reactions, sun sensitivity, and nail toughening. There are rare reports of abdominal pain, loss of appetite, vomiting, nausea, flatulence (gas), constipation, heartburn, and diarrhea. Based on several human cases, temporary increases in blood pressure and heart rate, as well as palpitations may occur with glucosamine/chondroitin products. Based on animal research, glucosamine theoretically may increase the risk for eye cataract formation.
                                It remains unclear if glucosamine alters blood sugar levels. Several human studies suggest no effects on blood sugar, while other research reports effects on insulin. Preliminary studies show no effect on mean hemoglobin A1c concentrations in patients with type 2 diabetes mellitus. Caution is advised in patients with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.
                                In theory glucosamine may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
                                In several human cases, abnormal increased amounts of protein were found in the urine of patients receiving glucosamine/chondroitin products. The clinical meaning of this is unclear. Glucosamine is removed from the body mainly in the urine, and elimination of glucosamine from the body is delayed in people with reduced kidney function. Increased blood levels of creatine phosphokinase may occur with glucosamine/chondroitin, which may be due to impurities in some products. This may alter certain laboratory tests measured by healthcare providers.
                                Preliminary data suggest that glucosamine may modulate the immune system, although the clinical relevance of this is not clear.

                                Hopefully my bolds will come thru, This is obviously a human study, and equine are different, but the funding is just not there for the study of equines, I can only assume.

                                THis is what I was referring to when discussing the equine deaths in eventing- a change in what we are feeding our horses that may be causing the sudden rise in pulmonary hemorrhage.

                                  I would think if you have healed ulcers [and how do you KNOW?] the Glucosamine would be ok, just not when you have an active bleeding ulcer, based on that above.

                                  Since these are human studies, you have to wonder at what dose/wt these findings were 'found' and how that relates to the doses we give horses?

                                    MSM, Chondroitin, Cetyl M & ulcers

                                    None of the above will exacerbate or cause ulcers. In fact they should help them.
                                    Glucosamine can cause bleeding so if the horse has an active ulcer, so it won't help it. But it won't cause an ulcer in a normal horse.

                                    Treat the ulcer with omeprazole/ranitidine but don't worry about the MSM, Chondriotin, Cetyl M etc. Stop the Glucosamine until the ulcers are no longer active. Usually 14 -20 days on full dose omeprazole.

                                    Use a feed through anti-acid like TractGard once the ulcers are gone to reduce the chances of it's reappearance

                                    Good Luck
