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!

  • What is the longest your broodmare has ever held out?

    Not sure why I want to scare myself or maybe misery loves company LOL
    Our pony will be a year from last breeding date tomorrow. Mine usually go much earlier than the standard "342" you read about.
    She finally is developing a bag but not a lot to express out of it. I got enough to try to milk test it but I had to divide the formula by 3, so not sure how accurate it would be. Calcium was over 250 and PH was 7.2
    So hopefully soon.
    What is the longest your mares have ever held out. Do you notice a difference with maidens? How about the time of year they are due?

    And just for fun, here is my girl who strangely finds pleasure in an owner who is sleep deprived.

        Last summer I had an older mare go 385, not her first, and a maiden go 311. Both were healthy foals. They keep you guessing....


        • #5
          382 days - and she is due in 3 weeks, and is looking barely pregnant, so I'm guessing we're in for another marathon. Her babies come out big and well-cooked!

            Client mare went 405. Produced small but healthy foal


            • #7
              Lotty cooked her first foal for 373 days. I forget how long she carried her second, well fewer than that. I put her in before dinner one evening, thinking that I would put her foal monitor on after dinner but when I went out there was the foal, up and dried

                We have an article on our website that discusses pregnancy duration (follow that link for the article). It has a questionnaire at the foot of the page asking what the gestational duration of the reader's live foal was - you can view the results without posting an answer by clicking on a link - we have over 4,000 reported pregnancy durations which currently report as below.

                We would appreciate it if everyone would take the time to update the statistics when their mares have foaled.

                319 Days or fewer: 4.61%
                320-326 Days: 6.98%
                327-332 Days: 7.62%
                333-338 Days: 9.53%
                339-344 Days: 14.60%
                345-350 Days: 12.62%
                351-356 Days: 8.75%
                357-362 Days: 5.81%
                363-370 Days: 8.48%
                371 Days or greater: 21.00%
                Total Foalings Reported: 4081

                  Jos - do you guys coorelate those stats with time of year. I thought I remembered early due dates "tend" to cook longer.

                  I am definitely looking this thread from my mares They don't need to get any ideas

                        Our "record" happened last year -- 379 days! For my daughter's maiden mare. She was beside herself by the time the foal finally arrived!

                        Interestingly, the mare due at the same time went 372 days, so both went over. The rest of the mares were about normal last year.

                        Both "overbaked" colts had very, very long manes -- like everything else had stopped, but the mane hair kept growing!!

                          No. they're just flat durations. The further away from the summer solstice, the longer the gestational duration tends to be.

                          And 445 days is the longest on record with a live foal - in Australia a few years ago.

                              Wow!! I am pretty sure I would have a heart attack it any of my mares went that long!! The longest my mare has ever gone (with 4 foals) was 333 days, the shortest was 321. All perfectly cooked (and between 11pm-12am I might add!)

                              The above mare's first filly had her first colt at 323 days...again perfectly cooked at about 11pm.

                              I am curious to see how my maiden mare (foal out of first mare, 1/2 sister to second) does in 2014!

                              Best of luck with your mare!! I cannot believe she hasn't foaled yet!! I am stressed for you!! :S

                                  around 365...twice. Once the mare appeared to be progressing slowly but normally. The other looked like she should have had the kid 2 weeks ago and the foal was about ready to FALL out....never saw a mare with a behind that lax. All she did is stand with her butt parked up against a stall wall like she was trying to hold it in. I joked she had her legs crossed for the last 2 weeks.One the whole...mares due quite early in the season go long and ones due late in the season go early. I figure it is Ma Natures way of trying to give momma ideal grazing/foaling conditions.Shortest gestations: 310 for a preemie looking red bag foal: small, shiny/fine coat, knees with flexion contractures. He was not quite baked. Next was 320...fully cooked looking colt o/o maiden mare with no bag/no signs of foaling. She ran into the barn, gobbled up her dinner around 6 pm. For some reason I went out to the barn at 10 pm and there was a foal up and nursing in the stall. The one due now is average....at 339 she waxed 3 days ago....so any time now. Most of my foals have run around the 340 to 345 average.

                                    Mine typically foal between 330 days and 344 days. If I remember correctly, our personal farm average is 338 days. The later/hotter the year, the earlier they tend to go. I have only had a couple of mares go longer than 350 days, but I think that is because most of ours are due in May, June, and July when the weather is warmer.

                                      I had a maiden foal at day 378. Her filly was born looking very underdeveloped and weak, but it now a healthy, normal-looking 4 year old.

                                      I had another mare have a colt at day 307, just last year. Although he was small, he was otherwise completely normal and needed no assisstance with anything. This mare also had a colt in 2010 at day 312, who was very large and fully developed. She has had 2 fillies both born around day 340.

                                        We had a 364 last year! Frozen so we knew to the minute conception. Experienced mare, biggest, most beautiful foal I've ever seen. Delivery issues but both made it.
