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.

  • ET - cycling two mares... challenge?

    I am considering doing an ET next year. It would be my first try. The donor mare usually get in foal on first cycle, with 1/2 dose of frozen (at least the last 2 years... ). She is in foal this year, and due within a week of another of my mare, also in foal.

    I am not particulary fond of using one of the recip mares of my vet, as I am very concerned about temperament and manners of my mares, and I don't want to have to spend a year with a unknown temperament, unknown level of handling etc.

    My other mare who is in foal and due around the same time than the donor mare is going on her 16th birthday next year. She is a fairly easy breeder for the last 3 years (1 try in 2010 fresh, 1 try in 2011 fresh, 2 tries in 2012 fresh... all resulted in heathy foals, uncomplicated births and pregnancies). She is a great mother, an easy keeper and her foals are gifted with lovely temperaments. I would consider her to be the receip mare... Am I a fool to want to try to use her as the receipient mare?

    What would be the protocol to cycle the mares, so I could send them to my vet's farm only when they approach the right time for the donor to start to be monitored for insemination... and receipient following up?

    I have the whole winter to come up with a doable plan.

    Thanks for your inputs. I would only try once, as if it does not work, I would simply bred the donor mare and let her keep the embryo. But I would love to get one ET and one foal out of this mare in 2014.

    I think typically (and you know my level of expertise on this ) you would have at least two recipient mares to synch. Don't you have another special lady who could take up the job if all fails with recip #1?

      I personally wouldn't use a mare of that age. In addition, as everyone else mentioned, you should try to sync at least 2 recips. Nothing worse than flushing twin embryos and having only 1 recip!
      Various ways to sync them; you can use PE, you can use Regumate, etc.

        I have a 2012 ET colt and I used one of the vets mares for the surrogate. You want as many odds on your side that you possibly can to be successful. It would be nice to use one of your own mares but the vets that are really into this procedure usually have 100's of mares to choose from at the exact time when they are needed. My mare double or triple ovulates giving me a better chance of one and possibly hit the jackpot and retrieve 2 embryos. With all of that on my side I was unsuccessful in retrieving an embryo this year. I will try again in the Spring. My suggestion would be to do everything you can to help make the procedure easier and successful. Good luck!

          If you are using Transbio, her mares are always nice, I have used them a fe times. so no worries. That way she can do a good synchro, and increase your odds for success.
          If you arent, I have used my own mare a few times as ET, it isnt tough with hormones to synch them.
          You need to ask your repro vet when to give what, and then he/she will make sure you have the recip a few days behind the donor.

            When I DID NOT use a ET center's mares, I cycled 4 of my own, all young , all either maiden or had only one foal. I was very lucky to have one of those four work, on each first try, of course it was my riding horse - both times. At the center , it took several cycles, and both mares I leased were difficult ( one was dangerous to us, the other was clumsy with the foal), even tho one of the mares was not a maiden.

            Do all u can to stack the deck in your favor, it can get very expensive, very fast.

              We had no problems cycling ours together. We started the donor on P&E and then started two other mares 1.5 days later. We had basically no issues with ovulation timing (we did 5 attempts over 2 years)... using two recips is definitely better because one time we did have one that ovulated too soon but the other cooperated well.

                I have a question in regards to using a young maiden mares (5,6 year olds)...is there any research out there as to how much it decreases your conception rates vs. using a mare that has had one foal?


                • #9
                  I haven't seen any research on maiden vs. 1-foal mares, but I can say that in my personal experience the success rates are the same. I've used multiple maiden mares for my own ETs and definitely will continue to do so. However, I treat my maiden recips the same as the non-maidens; everyone has a culture and a biopsy. I've seen maiden mares with IIB biopsies that we never could get pregnant (not recips mares, but mares to carry), so I won't use any mare that hasn't been biopsied. But that is just me personally. If you are using a large commercial herd then you probably won't have that option.
