Diet Experiment Collaboration?

rkhorne Oct 26, 2006 10:16 PM

I've had enough positive results on my ant-less diet experiment to suggest taking it to the next level.

I'm interested in setting up a scientific experiment dedicated to investigating HL captive care diet requirements in a collaborative environment. I figure the experiment will require at least 3 individuals to insure certain scientific protocols are met, but also to defray the costs.

Some of the requirements for the experimentors....advanced to expert experience raising HL's in captivity, access to CB offspring, enough funds and dedication to support a 3 year experiment, a basic understanding of the scientific principles, principles and methods necessary for such an experiment, a tolerance for the enevitable losses that will occur, and enough flexibility and openess to think outside the box.

If you're interested, please email me so we can get the ball rolling.

Thanks,
Roger

RK, what would the ultimate goal of your experiment be? To feed HL's non-ant diets? First of all what ever I am saying here is coming from me and no one else, but I have intimated before that in the wild the vast majority of scats that I have personally observed and this is over a 40 year period has been loaded with ants almost in every case. I readily admit I have found scats with other insects and as I have already stated horned lizards like all lizards are opportunistic and certianly will eat a moth a bee or what ever given the chance, but since the overwhelming scientific literature and personal information I have collected myself over the years your asking me to "think out side of the box" and while you may be having a great expereince with this, and frankly I am not dogmatic in the sense you can do what ever you want with your horned lizards, but I don't understand the sense in which you consider this thinking as "out side of the box", making a horned lizard not eat ants when it is an established fact that they are designed to eat ants, all their mouth mechanisms and defenses are set up to do exactly that. So I'll ask once more as I did in an earlier post, with no sense of anamosity; just the one question, what is the utlimate goal of not feeding a horned lizard ants?

Is it economic? Is it to prove you can do this? I guess maybe when I here you ask me to think out of the box, nature set the box in motion long ago, why is it that mankind must insist on changing and challenging the laws and protocals of natural life? Who really knows better????

Lou,
I too am curious if their is something in ants that HLs require. I'm not so sure their is. It's true HLs have adapted to eat numerous small prey and the ability to withstand venom but this is probably because their is less competition for this food source not because they require the ants. Many people thought HLs required formic acid but this was proven false. Most the ant species HLs feed on don't contain formic acid.

In my case and many others I speak with find it to be much cheaper to feed ants than to buy crickets all the time. In most areas their is usually an ant species safe for HLs to eat and they can be collected free of charge. So I don't think it would be economical to use crickets.

I personally would like to run an experiment to see what diet captive HLs do the best on. If you have raised hatchlings you should know they are very intemidated by ants. Mine don't even eat that many ants even though they are very small but they go nuts over the pinheads. Some species do really well on mini mealworms making up most the diet but this is species specific. I recently found out P. cornutum does not do well on the mini mealworms.
Dogsand cats didn't feed on bagged food before they were domesticated. Their should be nothing wrong with people trying to find the best diets for captive HLs. To experiment on varied diets is beneficial. I have personally found my HLs stay much healthier on a varied diet rather than a strictly ant diet with the exception of P. solare. They do fine on a high ant diet

Also I wanted to add I have a group of young HLs that eat50 % crickets and 50 % crickets. When I crush their scats it looks like they eat 100% ants because the soft bodied crickets have been digested. Analyis of the gut content is the only way to accrutely measure the percentage of ants. Just some thoughts but all in all I think a study to find out what diet is best for HLs in captivity is greatly needed.

reptoman Oct 27, 2006 09:53 PM

Jeff-just to reiderate myself, I have seen mixed bugs in scat but I would have to say that for the most part I think an eye exame of a scat is able to detect the two and as I stated before have. Most of the scat I have looked at contained beetles or even wings of moths or flyiong insects. I don't know the ratio of possible crickets that could have been in those wild scats. But I am pretty sure they were mostly ants.

However I am just questioning the wisdom of this only because I think it's not an accident that horned lizards are designed to eat ants. As far as neonates. Some lizard species eat vegetation and then switch over and yes I have observed with several HL species that babies seem to go for small insects (pin-heads) more readily than ants. I have also found that Pacific horned lizards or at least mine I have observed eating vegetable matter when they are young. while Lester says he never has observed this, I have fed my Pacifics mixed and extremely finely chopped greens along with small insects.

The other thing I would mention is that in the wild is different than in a cage. Often Hl's are not in the middle of a swarm but sort of wait until one happens by but are close enough that they can take in a few here and there. Sort of stalkers, I am sure you've seen this. So maybe the reaction to ants in a cage is different than in the wild. Oh also have in the past several years ago had two different Texas Horned Lizards that I fed small King mealworms in an outside cage and I found they did not do well on them, but as soon as I offered them ants they seemed to come back. That's not science but just my own observation.

So I guess in this case we'll have to agree to disagree, I think that nature itself has set the ground work for hl's and as many herpitologists who have studied hl's in the field the overwheming evidence is that ants are a primary food source. So like I said if someone wants to go after that, then fine, I just think there has been a lot of reliable observation and work already done on these? You know a Chuckawalla lizard will eat king mealworms up in heart beat, but a diet of insects insead of vegetation will burn their kidneys and eventually kill them off not to stop them from becomeing obese as well.

So while hl's may go after other insects offered in a cage--do you have any concerns of the long term feeding insects and not ants--or maybe that's your point to me--maybe I missed that. I am going to continue to feed my hl's ants but yes I do feed mine occassional wax worms, small king mealworms, moths, grasshoppers (small) beetles, and other such fair, but the majority of the diet is ants. I haven't ever needed to give them supplements. They have hibernated well and my expereiece has been good over-all. I may have had a pointed ending to my post originally, but I also believe that is substantiated by nature so thats why I stated that........

I respect your insights and opinions - perhaps you can work with Rk and help him get this off the ground if you so feel inclined! Best to you Jeff!

Jeff, do you have a reference that proves they do not require formic acid? I just ask because you say it's been proven. Are you referring to Baur?

I personally don't feel they "require" formic acid or Pogos ( to live anyway ). But everything I've seen shows formic acid and Pogo's are beneficial to their health in several respects, and that ants which provide this are "small prey", conveniently. I'd say "requirement" in the sense that it seems to be "best" for them. There are also more possible complications that can arise from feeding excessive high fat and sodium feeders. It consumes more of the reptile's water stores to metabolize and puts more strain on the organs. Crickets are more completely digested. But it is still apparent in the scat what masses in the scat are not ants.

Less "competition" for the food source, or "requirement"? The reason why Darwin's chicken crossed the road doesn't really
matter at this point does it?

They are adapted to eat that food source. I don't think anyone disagees. So I would have to also ask: what is the advantage of trying to use "primary" food sources other than which it was adapted? Everything else in the world usually comes with a voided warranty warning or a bad unintended consequence when man tries to meddle with it. I don't see a problem with exploring for scientific answers...but what is the hypothesis and why does it need to be solved? I think it is economics, and HL marketability to the masses, bacause it can't be that Pogos are not good enough.

Most of the ant species they eat or will eat may not contain formic acid as you say. There are far more species available to them that don't have formic acid. But, which ant they eat the most of by volume is the question. If you listed "most" of the foods I ate, most of them would not be breakfast cereal, bread, meat, or pasta. But ask me what I eat the "most of"...and that is an entirely different question. Let's say a HL eats 20 different species of ant in it's range, and only 1 of those species contains formic acid. Does this mean it eats more of the others by volume than the formic acid variety?

I used to push the Pogo-less diet around here, and listened to Cable telling me repeatedly that they won't do well, particularly in the breeding area. I'm now confused as to why it is after my nearly 3 year experience, I no longer advocate such a diet, and Cable is now interested?

The only reasons I see for a Pogo-less diet, is for the economic/market/convenience reason. I admit that was one of my considerations in the past because other sources were more available. It's more economical ( or convenient ) for people to buy crickets instead of ants, or even gather ants. Ants can be bought more cheaply than crickets, but many more ants are required. Therefore, many people see it as more economic to buy a sack of crickets for a few dollars vs. buying a 1000 ants at several times the cost. They also very often think they'll get by even better by giving the lizard a few big ones instead of a lot of small ones. Gathering ants is not more economical either the way most people view it. Time is money, and most people probably won't go gather thousands of ants...especially if they don't live in a rural area and they have to drive and look; when they can just pop in to the pet store on the way home and pay 3 bucks for some crickets. The economical reason for using crikets can be justified in many ways. I think the economic/marketability standard is the wrong standard to go by when considering the best diet if that is the concern.

It's trouble to gather ants, and in reality costs me more to drive around and vacuum them up. I really don't have the time for it. I would probably still be using other things if I thought they were just as good. My girl works at Petco and can get plenty of cheap crickets. I don't even have to go over there myself. But I do see a difference in growth and activity levels, and I choose to keep using Pogos.

Todays domesticated dogs and cats in many ways only resemble their ancient feral ancestors. Many of these domestic breeds are purely man made. Rottweilers, Spaniels, Persian house cats...They didn't exist ten thousand years ago. Man created them. Now were feeding them things made up of mostly plant matter rather than real meat. Even so, such mammals are more highly variable in the foods they make use of. Reptiles we all know are more tailored to a certain type of prey in many cases, like the Horned Lizard is.

Not bashing anybody. I don't think the results would prove the diet beneficial, but nontheless would be of interest. I just think nature already worked out that question and Horned Lizards have a lot of "evolution" in the domestic department before something else could be better for them. Is the experiement to really answer the question: "what is better for them"? Or is it something else? That's my question.

Cable_Hogue Oct 29, 2006 06:22 AM

Very well said FS.
As you know, I tend to heavily agree.
"I'm now confused as to why it is after my nearly 3 year experience, I no longer advocate such a diet, and Cable is now interested?"
The reason I am interested is to see this constantly recurring question laid to rest. Unfortunately I think this study may only do so partially. We all know that the different species have varied natural diets, some of which are far less ant specific than others. If you wanted to try this with solare, well, I think it would show crickets or other non-ant items to be a very poor choice in a short time. To complete this experiment for all HLs it would take many years and must include all species... or, you could not say this answers the question regarding HL diet, only "this" species of HL's diet. But this is a start!

Honestly, I don't think it will show a "no ant" diet as a viable substitute as much as it will show whether an HL will be alive after a prolonged non-ant diet. If an HL will live 10 years on an ant diet but only 5 on a non-ant diet, is that good enough? I would think one of the controls would need to be having a group that gets ants in line with their natural percentage so the two groups can be compared.
Roger didn't say "crickets" so it would seem all options other than ants are fair game, but this would also need to be defined in the parameters of the experiment.

Regarding formic acid, there is only one reference in a scientific study (by Bauer) that "seems" to indicate a more acidic balance in the dietary tract of HL's seems beneficial. But even this was not a specific study on this issue. It was a side note in his paper. It's my understanding that the venom in ants is a protein, not an acid. So in regard to the HLs noted venom tolerance (blood factors) this protein would seem more at issue than the acid they may contain in relation to blood chemistry. I am guessing here when I say it may be an enzyme that neutralizes the venom protein. Without venom will this build up and cause health issues? Is the byproduct of the venom breakdown an important dietary component? This experiment will at best only indirectly answer this question.

If it can be shown by this study that HLs do not fair as well as their ant fed siblings perhaps it will inspire a true study in the scientific cummunity directed exactly toward finding out why. And also lend credence to the hobby for an ant inclusive diet as well.

The opportunity for dietary study of HLs seems quit large. No ants? Ants? Which ants? Blood chemistry changes? Other less apparent deficiencies? Hydration differences (control)? and so forth.

Great thread!

I think you both hit all the same thinking and questions I had about Hl's and their food protocols. I appreciate the discussion, I hope my thinking on this wasn't percieved as bashing anyone.... I certianly appreciate the exchange, amd per my previous post about different groups for different insects and a control group, I believe you need to also seriously consider having one or more horned lizards medically examined or if they should die 2 or three years down the road have a casual exam to find out not just what they died from but also to examine their kidneys and other organs compare to a healthy HL. You all hit the same areas that I did with my mind, including scat, formic acid, small mouth for small insects, teeth made for ants: but I am still not dogmatic in feeding occasional other insects as well.... Cheers all!! Very good posts no matter what side of the line your on.................

Perfectly put cable.

Jeff Judd Oct 29, 2006 09:48 AM

Fireside,
Please refer to Wade Sherbrookes article in Reptiles Magazine and the article Phrynosoma solare raised on crickets and without UVB.

Now I'll ask you what scientific evedince do you have to support the idea they require formic acid or ants for that matter?

In keeping HLs for many years I have found prey size is the most important aspect in feeding HLs.

Since you missed the point with the dogs and cats I'll make it simple for you. Bearded dragons do very well and have been successfully bred through multiple generations in captivity yet they do not eat vegetation and insects from the wilds of Australia. Most people feed them crickets, mealworms and romaine lettuce. It would be impossible for most anybody to replicate the insects a reptile consumes in the wild even HLs. It has been proven that during certain times of the year when say beetles and grasshoppers are more abundant they will make up the majority of a HLs diet. Many scientists believe this is a way to build up fat reserves. Most species of HL actually have a highly variable natural diet. Only a few are truley ant specialists. Please refer to Montanuccis article on phrynosoma jaw structure.

The reason HLs have to eat so many ants each day to stay healthy is because they are of little nutritional value. In captivity I personally find they stay much healthier on an a varied diet so I'll continue to feed my HLs a varied diet.

If RK has successfully raised and bred HLs on an antless diet good for him. I would like to ask both you and reptomen to post some of pics of your captive bred HLs. Since you have their husbandry down you should have no problems breeding them right?

reptoman Oct 29, 2006 10:53 PM

Hey Jeff- I am not getting into a you know____ what contest with anyone here. I stated my opinion originally and followed up with some ideas for those that want to persue insects. I already admitted that I do feed mine a mixture of ants and insects but in my case mostly ants--and I also aluded to articles and bonified observations about the fact that hls do in fact eat beetles and other types of insects and from time to time IE bees as well observed in San diego County with Paifics. As far as pircutre of my captive borns I am currently stdying one specie and that is Solare. I have bred many amny pafific hls and also desrt hls in the past. But that was many years ago before all these discussions were even an issue. So I detect a little bit of a flame from you about it, but you must be missing the tenor of my posts completely. If you feed yours half and half or what ever I'm fine with that, I think some of our species are variable about feeding--so I'm not posting to soe seeds of discord. I just have an opinion humbly no matter how uninformed it may be. If you've got it all figured out then great, I'm gald for you.......Best to you.

rkhorne Nov 01, 2006 10:56 AM

Fireside, I can’t speak for anyone here, but my explanations to some of the valid questions you raised are as follows:

What is the advantage of trying to use "primary" food sources other than which it was adapted?....

First off, I reserve the right to debate the “adapted” portion of the question in a separate post….but as for the question of why feed them something other then ants….

1. The requirement for the Ant Diet has not been scientifically proven.
a. I’m a degreed scientist. I conduct scientific tests on a daily basis for a living and have been doing so for 20 years now. Over the years I’ve learned not to substitute assumptions, opinions, group think, or even field observations in place of scientifically proven facts. So far I have not found any scientific based data that says Ants are a mandatory dietary requirement for the long term captive care success of HL’s. I’d simply like to see it either proven or disproven through the scientific method.
2. Elimination of parasites associated with wild caught ants.
a. Every time we feed HL’s WC ants we run a much higher risk of introducing parasites then when we feed them captive raised insects. (Yup, this too needs to be proven, I hope to do this during the experiment, but for now I think it’s a pretty a fair assumption).
3. Continuous access to a readily available food source.
a. For most of us, easy and continuous access to Harvester Ants is not nearly as easy as access to crickets, meal worms, roaches (?!), etc.
b. I’d like to say there’s a cost benefit using crickets, but after 2 years of buying at least a 1000 pinheads/wk at $15 a pop, it appears the cost factor is a push. (Don’t bother doing the math, I know I’m well over $3k doing my preliminary case study so far. And now I’m about to start it all over again?!)
4. Better control of the gut loading benefits of the food source.
a. Harvester Ants appear to have a much more restricted diet then crickets, roaches, etc. Generally speaking, you can much more easily “boost” the vitamin intake of your lizard buy gut loading an crickets then you can an ant.
5. Harvester Ants may become extinct.
a. When considering the known destruction of Harvester Ant populations due to human development, along with the associated Argentine Ant and Fire Ant invasions, coupled with the human population growth projections over the next 50 years, I’m concerned that Harvester Ants may not be available in the future to support any viable Wild or Captive HL populations. If this becomes a reality, then there’s a genuine need to establish an alternative diet to insure their survival. I could go deeper into this subject, and I’ll be glad to debate this premise outside of this post, but for now, I just ask you to consider the possibility of the occurrence, and if it was to happen, what steps should we be taking now to insure their survival.

What is the hypothesis and why does it need to be solved? All I can say is refer to comment #5 above. I’ve first hand witnessed significant destruction of HL habitat in my short life span. Given the projected human population explosion which will undoubtedly occurred in their remaining natural habitats, I’m convinced that in order to save the various US species from ultimate extinction something needs to be done with respect to their captive care/captive propagation science. The Phryosoma.org & Phrynosoma.com web sites represent very, very good first steps down this path. What’s needed now is to start filling those web sites with the scientifically based information required to move the ball forward. The proper way to do that is to first select a care/propagation parameter to be tested, and then perform compare and contrast type scientifically based experiments to determine the optimum solution for the parameter under test. My post is recommending we address the dietary requirement parameter. I conducted my own personal experiment just to see if crickets were a viable alternative and concluded that they are. The obvious next step is to do the full-up compare contrast experiment not only to try and validate my findings, but more importantly, to try and determine the best approach.

Is the experiement to really answer the question: "what is better for them"? Or is it something else? That's my question…My answer…both. I personally want to know the best captive care solution. I know ants work very well, but are they the best…I haven’t see any scientific based data to prove or disprove that premise. Being a real scientist, I want to see the data before I draw any conclusions. Is it something else? Yup….as stated above, I have an additional motive for pursuing the subject, I want to do my part to save the species. I’m concerned about the time frame, the clock is ticking, I’m not seeing the academic world pushing the envelope in this area, so I believe it’s up to us hobbyist to get the job done before we loose them altogether.

BTW… Diet testing is just one parameter to investigate. Similar experiments are needed to determine the optimum requirement for seasonal cycles, light, temp, substrate, hydration techniques, etc.

reptoman Nov 01, 2006 03:32 PM

R.K. I am ready to get off of this conversation because of the tenor it took. Yes I made a comment that could have been taken as a put down, but it wasn't--it was just observation based on years of experience with respect to nature. So I am going to continue to recommend ants and yes a mixture of occasional insects as I stated before. Actually I can appreciate your perpective and opassion, I would definately explore including having a 3 or 4 year old non-ant diet animal medically comapred to a ant fed specimen to see if there has been any degredation to the organs by this.

Now I am not a scientist but I am very much an observer and reader R.K. And while your primise is fine with me--I do want to say that most of the sudy's (scientific) and observations (Go back to hobart M. Smith or before Ditmars, etc.) have all observed that "in the wild" ants are one of the or the prefered meal of horned lizards to a more or less degree depending on specie. I assume if you've been raised in our school systems then you may or probably accept evolution as a viable model, if I am wrong correct me--but given the scientific method, I would think you could not just cast away the evolutionary and natural history facts about these lizards?

I think if you read Richard Montinucci or even look at previous posts from one of our best authorities on Hl's (Dr. Lester Milroy III) I think you'd have to at least admit that there opinions were formed by science as well. Lester works for the state of California as a biologist and Hl's is his specific expertise - in California he's the man or at least one of them anyway.

Also some of the stuff you alude to at the web-site as a good start, but maybe that it's not scientific, if you look at the ant chart and species that is scientific completely. I think it's good to have people such as yourself willing to challenge or come with new ideas. Many of us have heard this before but the fact that you want to take it to a higher level is good, I just don't want you to throw away the baby with the bathwater because actually the burden of proof is on you...

So now if I can be of assistance or help with some ideas about the protcols and end result goals that might be considered I would be glad to help, I think this is my last post because I am more interested in learning at 56 I am still teachable, also one last thing how many years have you been into horned lizards and also what state do you hail from? I am from Texas now but spent much of my life in California. Cheers!

RK, thank you for your more thought critical and professional reply.

I am open to your debate about "adapted", but I don't want to play symantics if you have a better word in mind...however you have made many very fast and loose unsupported assumptions in other matters. For example your "fair assumption" in point #2. I understand a hypothesis has to start somewhere...but there are some that are more assured than others. I think my "adapted" statment stands on firm scientific ground. As a scientist, you do buy into Darwinism, do you not? Creationism could also be argued...but that's all moot anyway. The best proof that they are adapted is the plain multidudes of years of previous scientific and casual study of the creatures. Is it just coincidence that HL's are so conveniently suited in many ways to eat ants, and that they do in numbers in the wild? Does your hypothesis allow that nature or HL's are making a mistake...or do you refute that this knowledge is accurate or complete? I agree to take further debate on that point at a later date in another thread.

As to point 1 of you arguement:
I agree. I make no assumptions that it is "required". I.e. the animal will die without their chemical composition. I have already verified that myself over the years, though I maintain there are many reasons alternative diets can be dangerous...and can cause or contribute to death in many ways.

I applaud your scientific approach and critical thought skills. However, do not make more out of your degree than is necessary. Credentials many times are over-rated and merely come by way of someone else's previous opinons being taught in a classroom. The same dangers of assumption are present rummaging around in the refuse piles of many a scientific journal or university classrooms, and are perpetuated as "law" or informed opinion through years of academic rubber stamping.

A scientist is someone who observes and can make thought critical analyses in a methodical and logical way to answer a question. That's all. One does not require a degree to have that ability.

Point 2:
I agree to a degree...that all depends on the conditions CB feeders are being kept in. Ants could be kept in CB environment as well and reduce these risks. So why is that not within your approach or concern?

Point 3:
I think this further establishes my point that there is a financial market concern in these dietary debates. "Easy and continuous access" to harvester ants can be debated as very subjective based on a persons means. Ants can be ordered easily enough, and even propagated with a little more effort than is required for other feeders.
I guarantee whatever you have paid in the last two years in the way of crickets, it would have been more with ants if you had to purchase them...and there are many more people selling crickets that offer better deals than what you have paid for 1000. The cost benefit is there even if you don't yet realize it.

Point 4:
Harvester ants have a very varied diet that is easily met by using common garden items or items available in your fridge...as well as insects. In this manner their "gut loading" can be controlled also if need be. I maintain "gut loading benefits" are really only an issue if you aren't using harvester ants. No I don't have data on that...but it's moot anyway if I can illustrate that gut loading control is just as easy with ants. And why wouldn't it be?

Point 5:
That's a real leap my degreed friend! HL's may be long gone well before the ants. I don't think there's a danger of Pogo's going extinct anytime soon. They move around and adapt pretty well, as I've seen them in downtown metro areas here at traffic intersections. They also propagate much better than HL's do and bounce back from such things in different spots. The colonies can sustain workers being stepped on or run over by cars...the HL cannot survive such things.

Your point here seems to call alarm to the fact that the ants are in danger...therefore we must work to find a lifeboat for the lizards which is another food source. I don't think this is grounded in science or casual observation.

If I were to entertain your question of the possibilty, then I would say you have the wrong question in mind. The question then becomes "how do you mitigate the reduction of the Pogo populations." It's folly to suggest that we just jump right to how to find another diet for the lizards at this point.

Your point also is an admission that other food sources are merely secondary preference out of necessity due to a panicked assumption about of extinction of ants.

I think your point 5 is the least grounded in scientific merit.

I won't make a blatant accusation about your motives and true intent about saving HL's and being concerned for the genus. I don't know that you don't care. But I think I have a valid point to question your scientific house being in order if that is your real concern. You're focus is way way off if that is the concern. There are many many many more things that a "real scientist" could do in that respect which would be much more beneficial to saving Horned Lizards...than trying to figure out a more convenient and readily available captive food source.

What of the wild populations? Where does your concern for their continued existence fit into your approach? Your focus seems to be only for how to keep them in captivity. Does your concern or scientific approach involve prevention of the vase from being shattered in the first place? Or do you really think the best way to save the vase at this point is to prepare to glue the pieces back together after it shatters!? Seems most unscientific to me.

Hi Roger,
Don't know if you got my email. I am interested. I think this is worth testing out. Even if it proves not to be a viable diet long term, it is still valuable information.
Do you have much put tegether in the way of parameters for the experiment?

Roger--I think that a consideration would to have one of the subjects x-rayed or examined medically after several years of non-ant diet, that would be good and also make a comparison of breeding, egg depositions, and health of neonates. That would also be helpful to know........

Will you have different groups feeding on certian insects? It might be that ceretian insects might be more problematic than others over a long period of time and that would be good to document as well......
