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.

Thanks for being a part of the COTH forums!

    I'd be interested in"real on farm conditions" and "strict scientific controls" being specified.

    I would also be interested in a published peer reviewed report from another possibly more unbiased publication.
    Some riders change their horse, they change their saddle, they change their teacher; they never change themselves.

    Remember the horse does all the work, we just sit there and look pretty.

        Interesting that the Organic Journal and the newspaper article failed to include this part of the conclusions:

        There were no statistically significant differences in food intake, feed conversion ratios,number or nature of illnesses, number or nature of veterinary interventions, veterinarycosts or mortality between the non-GM-fed and GM-fed groups of pigs. Mortalities were13% and 14% for the non-GM-fed and GM-fed groups respectively, which are withinexpected rates for US commercial piggeries. All dead pigs were autopsied by blindedveterinarians and deaths were assessed as due to usual commercial piggery-relatedmatters and not to their diets. There was also no difference in body weights between thetwo dietary groups, initially, during, or at the end of the experiment.
        If you take out ONE pig in the GM group with an enlarged uterus, there was no difference between the groups.

        Mischief of small numbers and probably a good bit of publication bias.

        What the study should do is raise questions as to why pigs on the GM diet had more stomach inflammation, and whether this inflammation was clinically important to the health of the pig in a meaningful way. And spur more research on that topic. Leaping beyond that question makes little sense.

        Medical "journalism", however, is interested in HEADLINES and not necessarily the boring, pedantic, plodding pace of research. If this weren't a political/social/emotional landmine of a topic, this would be met with large yawns even among pig farmers.

          And whether the stomach issues alter the nutritional profile of their meat.

          And more.

            And why almost 15% of them die in "normal piggery circumstances" regardless of diet! That would seem to be a very expensive statistic.

              "Normal piggery circumstances" are cruel. Sows are kept in "sow stalls" which is basically a tiny box where all they can do is stand up or lie down. Meat pigs are kept inside in crowded pens or similar stalls to the sows. This means depressed, anxious pigs who are prone to disease. But in the end it saves the farmers money even with 15% loss.

                from Chicago Trib article

                David Edwards, who is the director of animal biotechnology for biotech industry trade organization BIO, questions the methodology and notes that overall stomach inflammation was more common in non-GM fed pigs, even though severe stomach inflammation was more common in the GM-fed group.

                  I'm surprised the death rate is as low as 15%

                  SGray - assuming that's true (and not doubting it) then I wonder if it's similar to what happens to feedlot cattle who are being fed high grain diets - it is not what they are meant to eat, therefore really upsets the bacterial colony, which does cause digestive issues of all sorts, which then causes diseases, which then requires the widespread use of abx, and so on.

                    Cant really compare cattle to swine... totally different stomachs. Swine are actually similar to horses in that they have a non-glandular portion up by the cardia that is prone to ulcers. Cattle, of course, have a rumen. High grain diets are digested by the rumen bacteria and results in pH drop in the rumen, which then kills off the bacteria. The ABx use in cattle is primarily used to adjust the flora of the rumen. Swine aren't doing this type of digestion, I would think a high-grain diet in swine would cause similar issues as horses (i.e. ulcers) but I don't know enough about it to say for sure.

                      Yes, I know the stomachs are different, but for ANY animal, and that includes us, when you feed they way many of these feed lots "feed up" the animals, it DOES alter things to some degree. That, plus the stress of how they are housed during it all, plus the relatively unsanitary conditions, stresses these animals out to a great degree.

                        15% is pretty normal, even lower than a lot of producers experience. They often wean at 2-3 weeks so that they can get litters out of their sows- I guess it must work itself out. But high piglet mortalities are a huge issue in the swine industry with every producer. Their digestive systems are really not developed enough for much other than milk at that point, which is why they start them out on a "complex starter diet" which is more expensive. It usually includes some milk products, plasma, etc, and they gradually transition them to the corn/soy that they'll end up finishing them on. Sanitary conditions in hog barns are a huge issue, too. A pig's immune system isn't all that great when they're 20 days old, especially if they aren't getting the nutrition that they really need.

                          Normal piggery circumstances = horribly inhumane living conditions. Just disgusting.

                              What part? I pulled the actual full article and read it, including the "fine print". Just double checked . . . the paragraph I quoted is the first one in the "RESULTS" section of the scientific paper. (not the newspaper)

                              http://www.organic-systems.org/journal/81/8106.pdf

                              Abstracts are how you "sell" your paper. You've got 250 words to make it sound sexy, earth-shaking, and relevant.

                              Unfortunately, that is often the only part that medical "journalists" actually read.

                                  The GM foods probably don't need the herbicides.

                                    Roundup, for which many of the GM foods are created for, is not as persistent in either the environment or the plant as many other alternatives.

                                    EPA requires a very extensive program of tests for toxicology and residues for all pesticides to make sure that toxic amounts of pesticides are not possible when labels are followed and post treatment harvest intervals are met. Farmers are very careful to follow labels.

                                      Actually, they do. Many are round-up ready, but now the weeds are becoming resistant to round-up...so they're moving up to 2-4D. The others contain BT, but the insects are becoming resistant to BT.

                                        Hence the on my part. But I'd wager non-GMO foods are exposed to more herbicides than GMO ones. The study in question was not one of ORGANIC grains vs. GMO ones but rather "conventionally grown" non-GMO ones vs. GMO.
