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.

  • Horses born from Artificial Insemination are never first class horses...

    Hi Everyone,

    I’ve looked through numerous posts dating back but have not come across this topic, or rather claim, that I’ve found extremely disturbing...

    I’ve picked up a copy of Federico Tesio’s “In His Own Words” and haven’t progressed much into the read as I had to go over, again and again, his claims around artificial insemination. He states that clearly there is evidence that a horse produced through artificial insemination lacks that key ingredient that makes horse a winner, namely “nervous energy”. He goes on to elaborate on this phenomenon and actually supports it with carefully studied cases.

    He firmly states: “Artificial insemination results in a perfect reproduction of all the Mendelian characteristics but without transmitting the extra “nervous energy” that gives birth to the superior animal that is Nature’s masterpiece”.

    Here’s a link to parts of the book, please refer to Chapter One (page 21):
    http://books.google.com.sg/books?id=...age&q=&f=false

    Has this phenomenon been studied any further? Do we have evidence against his firm statements?

    Or even, do we know which top performers in this day and age have actually been born from Artificial Insemination, to abolish the claim of World’s finest horse breeder?!

    Look forward to your comments!

    Thanks

    I think it is important to note that Tesio died in 1954 and thus never even had an opportunity to evaluate the impact, if any, of AI using any method *we* know on the athletic aptitude of the horse. In addition, he bred TB racehorses, and we would not have a basis to compare within that part of the industry as, quite obviously, the Jockey Club requires live cover.

    With respect to sporthorses generally, presumably most of the top ones are bred via AI as very few WB breeders would consider allowing their mares or stallions to be bred through live cover.

      Everything Yankee Lawyer just said - and all top competition SJ's and Dressage horses are probably the result of AI.

      And as a totally different view, I have had 3 siblings born from one mare. 2 warmbloods AI and one TB live cover. I can't see anything that relates to what he's on about in the form of "nervous energy" being taken away from the AI bred horses versus the live cover one. If anything, the live cover baby was born broke. Hubby use to ride her in from the field as a 2yo with halter and leadrope before she was ever broken. Now had he tried that with Abba, he probably wouldn't be here anymore!

      Tesio was a brilliant man, but AI back in those days couldn't have been what it is today. Who knows, if he were alive today maybe he would be the forerunner in introducing AI to the TB industry.

      And as someone who breeds TB's I would be in favor of AI, but not ET and I don't think you could have one without the other. Part of what makes mares special is that mare and her value is diminished when you have 3 of her offspring being born in a year. And I'm not totally convinced with the ET donor mares either. I'm not saying any of those horses won't be good ones who are raised on a donor mare, but I think the "real" mare has a lot to offer her foal in terms of characterisitics. Yes, I would be in the small majority, but having watched my horses growing up in herds and seeing what they pick up from their moms, well I like it that way, with one notable exception.

        Interesting topic. I don't know if the "nervous energy" Tesio speaks of is needed in anything but a racehorse. I do believe that if turnout and socialization is limited (babies are hothoused), the soundness and competitive nature of a baby is highly at risk.

        Already in the TB world, a valuable mare might have to be bred live cover, and deliver her foal, but I know that some immediately give their baby to a nurse mare so they can return to the shed and warmer climates faster as well as keeping the foal safe from his rambunctious dam. I have no idea how common this is, but I would like to see numbers. The ones from this mare are mostly good runners, but would they have been world beaters if raised by their dam? Tesio's comments might be proven true with clones if we ever see enough to get an idea.

          I wouldn't have numbers for nurse mares either, but it would be interesting as it follows the point I made with the ET mare raised babies.

          I do know if the mare is in anyway viscious at all, then yes that foal is removed immediately. Common sense on a stud where you need to protect workers. Rags To Riches baby this year was raised on a nursemare.

          Having the opportunity to watch my young ones grow, seen how they've acted with moms and weanling groups, and then going on to break them you get to see what each mare brings to the table as far as raising their own. Because despite different stallions they each have defining characteristics of the one who raised them.

            Before I read the rest of the replies... was this book written in 1848? It just sounds like one of those weird science ideas of the long ago past. Written by someone with an agenda.

            Now in the interests of open-mindedness, I will consider it's possible there is some hormonal change in the uterus following copulation that makes a big difference in the development of the egg or something... and I will read everyone else's replies...

              twofatponies - I believe that the Tesio concept was that if Live Cover was employed in ALL breedings, the superior "sperm" would be the first one to cross the finish line and would make its way to the egg first, and get to be the one to fertilize it, but if you employ AI and have split that ejaculate into 2 or 3 or 5 doses, then only one of those mares is going to get the "winning" sperm and the other mares are all going to be stuck with "substandard" little swimmers instead ...

              In theory - I guess it makes sense but in reality, there is no correlation between the quickest swimmer produing the best moving dressage horse or the highest jumping jumper either or the hunter with the prettiest jump and the best work ethic

              And does the fastest swimming sperm = the fastest running race horse? I guess if that was correct, every single live cover conceived TB baby should be a superior race horse and we all know that is far from being the actual case ...

                  Tesio was a brilliant breeder.

                  But he beleived in a LOT of weird things.

                  Including, IIRC, that if you bred a mare to an "inferior" stallion, all her subsequent foals would be "inferior", even when bred to "superior" stallions. And the importance of skylights in broodmare's stalls.

                    OP don't worry, Tesio's theory has not held up. As people have already said, most all of the top horses in showjumping and dressage were produced by AI. The stallion owner checks the sperm for concentration and motility, or at least the stallion owner I used did (I happened to show up before collection, which was rather hilarious) to make sure the mare owner gets a good sample for her mare.

                    • #11
                      As few horses specifically bred for showjumping, dressage, etc., are being bred live cover then it seems to me there is no way to compare whether AI or LC produces the "better" horses. So logically, what we have is a level playing field with almost all high level competition horses being bred via AI, and as such we see some AIs are "better" than other AIs; as we have seen for centuries the same level playing field with TBs ...

                        Yep, not all ideas from brilliant fellows are created equal. I'd put the one quoted by the OP in the BS category.

                        Also, I have three ET foals on the ground this year that rival the best foals I have ever seen anywhere. Their real parents are stamped all over them. The ET moms (grand ladies that they are) just feed and care for them.

                        I also have an ET from 2004 who never met her true dam until she was a yearling. The filly is a behavioral clone of the true mother. She has the same personality and even the same restroom habits (puts everything in one corner of her stall and when she can she puts it through the bars into someone else's stall). I have watched all my ETs with great attention and can say that I see no diminution of the passing on of the dam's traits.

                          Before we toss the theory completely, merely for arguments sake (and ‘cause I’m stuck here waiting for a phone call), let’s say that the “winning” sperm in the live cover breeding race does in fact produce the best possible expression of the genes.

                          So, if the superior athlete is the product of live cover, then that is the high end of what the bloodline can produce. Now, if the superior athlete was produced AI, we could speculate that the live cover foals of the same breeding would be even better.

                          So, if Sandro Boy is the product of an AI breeding, we should all be trying to repeat his breeding live cover.

                            In a way I think this is being confused with in vitro. The sperm still has to swim, and unless the stallion has poor quality sperm, there's going to be good swimmers in every dose.

                                  I'm being a bit didactic here, and might be showing off as well, but at the time Tesio was forming his ideas, there was a prevalent European philosophy created by a Frenchman named Henri Bergson who postulated the existence of a "life force" which he called Elan Vital that was responsible for evolution and the improvement of living things.
                                  http://en.wikipedia.org/wiki/%C3%89lan_vital

                                  I'm fairly certain that what is translated in Tesio as "nervous energy" is very much a derivative of Bergson's Elan Vital. Given how the Western World at the time (early twentieth century) was fixated on all things sexual, it would make sense that sexual energy in the act of procreation would be the means by which Elan Vital was transmitted to the next generation.

                                    As brilliant as Tesio was he had some strange ideas.
                                    For example, he thought grey was a disease, not a color modifier. And because of his belief grey in the TB was almost bred out of the gene pool.

                                      That makes sense.(I don't mean I think it's true - just that I now understand how they might have thought that!)

                                      I do have a friend who has a breeding program with three pony stallions and a bunch of mares... she has a non-scientific theory that if a mare and stallion don't like each other, they shouldn't breed. She only does live cover anyway, but if there isn't a good attitude between the mare and stallion (assuming mare is in her cycle, etc.) she won't "force" the issue with restraint or AI, but try a different pairing (taking her own bloodline plans, conformation, etc. into account, too, of course).

                                        Tessio's hypotheses were formed in the absence of what is now considered common knowledge about the actual breeding process in the equine. The concept that "the best sperm will get there first" was formed - at least in part - with the view that the use of AI would give what may perhaps not be the best sperm a head start by the introduction of the insemination dose directly into the uterus. At that time, there was a strongly held belief that - as is seen in other species, notably (because of practical knowledge) humans - at the time of ejaculation, sperm were deposited into the vagina rather than the uterus. In fact, in the equine, as a result of a variety of factors, the ejaculate is usually deposited directly into the uterus, or at the very least under pressure into the cervix (which results in almost immediate transfer into the uterus) - in other words, there is no "head start" for sperm with the use of AI compared to live cover.

                                        Further to the above, newer knowledge has demonstrated that sperm are moved, once in the uterus, not solely by the motive force of sperm tail wiggling, but in fact to a great degree by uterine contractions. Tessio's argument therefore would have to be added to in order to adjust the "best sperm's" ability to take into account the "best uterus'" ability to provide motive force to a "poor sperm"!

                                        Then on top of that, we must consider that newer science has demonstrated that an almost equal number of sperm end up in BOTH oviducts - that ipsilateral to the developing follicle, and that contra-lateral. It is therefore necessary - if we decide we wish to endorse Tessio's theory - to develop a belief that a sperm (the best sperm none the less) not only has superior physical attributes in itself - which is somehow magically linked to the DNA that it carries - but that it also has superior intelligence and homing instinct enabling it to head for the correct oviduct adjacent to the pre-ovulatory follicle.

                                        So now, Tessio's theory has been expanded to "demonstrate" that the "best sperm" not only gets where its going first, but also has achieved stimulation of the uterus to provide contractions to aid it - and none of its several billion compatriots that are also along for the ride - and furthermore, has a well-developed brain or GPS equipment to ensure that it heads to the correct oviduct!

                                        While the Tessio theorists can expound at length on the hypotheses, they are starting to have a hard time to produce physical evidence in support... no brains or GPS equipment found in a sperm yet!
