Gut loading frenzy

I’m honestly not seeing the controversy with this, or how this would change most of your practices.

It is pretty clear that we can augment the nutritional content of feeders by offering diets rich in certain vitamins and minerals. (Look at research by Finke and others). The “gutloading” chart lists several greens and veggies that are packed with vitamins and minerals and have favorable calcium to phosphorus ratios (there’s a nice chart in Mader’s Reptile medicine and surgery with some of this information). As long as our insects can digest this stuff, their nutritional value is improving and this can be passed to the chameleon

it seems there are some things on that chart that could be potentially harmful that @PetNcs takes issue with. If these things (almonds, etc) have potential for harm, they should be omitted entirely from the process

Gutloading (feeding Insects directly prior to feeding them to the chameleon) should Include things that chameleon can absorb and benefit from if we intend to use their gut as a vector for our chameleons nutrition, and he gives suggestions on what you can usefor this process. Correct me if I’m wrong, but he also concedes that dusting feeders may make “gutloading” unnecessary

so if you feed Your insects high quality foods that increase their nutritional content you have satisfied part one of his suggestions
If you would like to enhance their available nutrition, just prior to feeding your feeders gutload them with bee pollen, calcium, and /or multivitamin, or just dust them. As @nightanole noted earlier, calcium can kill the insects Over time. I think it causes constipation (don’t quote me on that), so do this only as a gutloading addition

unless your only feed your bugs once just before you feed your Cham, you’re really not changing anything. Just feed them and dust them

Absolutely correct conclusion, thank you for rewording a bit but precisely my thoughts

I don't take offense. But I also think that the way I look at it is pretty common for how others will see it. I did not understand what you meant about my logic lacks feneral niolohical... and maybe I don't need to know lol.

It is funny because out of all the people that have jumped in on this thread. I am very modest in how I gutload and what I use compared to others. I keep mine very simple.

But again thank you for taking the time to have the conversation. :)

I Improved rhe spelling already, sorry, midnight here and my eyes get tired a bit
 
I have never seen you off the mark.

Nut I would be
Deeply and genuinely interested
What is the real percentage of the components of your “guloading products”
Whether in the sense of the debate theh are thiught as gutload or feeding feeders.
What research and scientific base are your products rhat you produce and sell on the market based on and what is rheir oholosophy and logic...

Ok friends, shall we cut a distinction here?

Gutloading = The practice of feeding your bugs a bunch of healthy stuff just before feeding them off, in the hopes that this partially digested stuff gets to our chameleon via the insects’ gut contents.

Nutrient maximization = The practice of always feeding your bugs maximally nutritious food so that our bugs are at their most nutritious at the time of consumption. This need not be based on the gut contents of the bugs.

I’m happy to hear alternative names for option 2.

I suggest HQ FEEDING OF FEEDERS

Love this discussion. This quote from the the original post is a lens to view this forum in general. "These all recommendations have absolutely no scientific basis, they are repeated and parotted imaginations and formulations of people that dare to introduce to the community things that absolutely do not make sense and are not backed with any measurable experience and no science."

My guess is most advice for chameleons is not based on scientifically tested hypothesis, let alone any studies in peer reviewed literature. This applies to both the concept that gut loading is not nutritionally beneficial to the chameleon but also toPetNcs statement that it "can even be harmful". Would be surprised if there was scientific basis for that too. We just don't know. This topic is even more fun because the effects of gut loading feeders is not easily tested by readily observable outcomes.

What we do know is based on biological plausibility (what makes the most sense?) and the collective experience in this group. These discussions that advance our understanding and make us think is the value this forum provides.

Thanks for starting the conversation (and your passion).
 
@RPCV said..."My guess is most advice for chameleons is not based on scientifically tested hypothesis, let alone any studies in peer reviewed literature"...most of my advice is based on what I have learned from keeping them...if what I do seems to help them live long healthy lives, I continue with it and tell others...if not I change it.
I'm sure there will always be improvements I to make....and other ways of doing things that work too.

You said..."These discussions that advance our understanding and make us think is the value this forum provides"...for sure.
 
There is sure is a lot of conjecture and heavy handed statements without any scientific backing on this thread. Let me help with that.

1. IT IS UNNATURAL - most of the shown ingredients you will never ever find in the stomachs of insects that are eaten by a Chameleons in the wild,
with few exceptions like maybe the juices of some fruits but definitely not apple... The reason is very simple, the insects living in areas that chameleons live in, have no access to this type of food and even if they would have, they would not eat it. So again, it is not natural.
Because we do not have access to the vegetation present in the home ranges of chameleon habitats as commercial produce. Just because you can't get one specific plant does not mean that another plant with a similar nutrient profile is going to be "unnatural". It may not be the same but it can have the same benefits. Please do tell me how "natural" the clothes on your back are compared to your ancestors. This is not a good argument to just say because it's not the exact same thing that is it unnatural and therefore harmful.

We do not recommend citrus or almonds in gutload so not even sure why you feel that is a battle worth fighting. Crickets are not ingesting large parts of plants that remain intact, they are digesting it into nutrients first, which then the chameleons consume. So whether or not chameleons can digest plant matter is irrelevant because feeders can.

All the concept of gut-loading, If it would be to increase the nutritional value of the feeder, is false. Because to increase the nutritional value the major part of the food inevitably must be digestible. And it is NOT.

The scientific papers listed above say that nutritional value of feeders does increase depending on what is fed, which is the entire purpose of gutloading. Do you have scientific sources that say otherwise?

Thanks for posting these papers. This is great evidence that high quality feeding of feeders increases their nutritional value.
 
I think this chart
shows an issue we have to deal with as chameleon keepers
84C0838C-7700-481B-93A2-D420CCE9894F.png

The column for chameleons is essentially blank due to the lack of data regarding wild diet and it’s nutritional value along with lack of research on their requirements.

I’ve heard some information regarding required dietary D3, but much of the rest of this is unknown

There are several papers that suggest that some chameleons regulate their uvb exposure depending on need. So, for example, panther chameleons given no dietary d3, will bask more. There’s a few pertinent articles sites in the bibliography of:
