>>Your opinion holds that variety in the diet is the key. Variety in the diet, so long as that variety follows natural-based guidelines, is always great for any reptile captive maintenance regime. But, it's often not a necessity and it can be slightly to largely inconvenient. Hence the origin of this thread - convenience. Variety of the proper origins will provide suitable nutrition, but, so will a lack of variety of the proper (albeit manipulated) origins.

What exactly does this mean????????
>>I'll digress for just a moment to point out that you provide more crucial varieties than varied diet when it comes to your turtles' well-being. You've shared pictures, and my thoughts here are based on those. Varieties of habitat. Your critters have access to a large area (compared to Rubbermaid limits) and thus a variety of temps, humidities, visual barriers, and so forth. Those are the varieties that a commercially prepared factor will never be able to try to match. Unlike the food. When you can provide proper variety of the environment, the food's not such a problem. Box turtles can live for years on a malnourishing diet if the habitat parameters are right; I say that only to emphasize how influential habitat can be. Provide great habitat and the food is secondary. Why? Because it doesn't work the other way around.

Definately disagree here... Nutrition forms the building blocks which are required for physical development. The environment provides the vehicle which is needed for those building blocks to be used. Even with the greatest nutrition in the world you are going to get nothing if the environment does not allow the animal to use that nutrition. On the other hand you are going to get nothing if you provide the most ideal environment and crap for nutrition.
>>The Reptomin and Mazuri stuff should go over fine once box turtles are deprived of more natural foods. Until that day, consider them "spoiled." Or rather, consider them maintained in a more natural state. The more natural the state they're in, the more natural the behavior. I've never been exposed to luteola, only ornata, but I can attest that I've never met one that would take a soaked, prepared food over a wriggling worm.

Some of these prepared diets do have a great deal of research behind them and actual nutritionists developing them. Most of the ingredients are included because of their usability. This makes many of these diets very nutritious almost to a fault.
>>Movement and odor seem to be the two prominent precursors to food acceptability when it comes to animal prey for box turtles. Scratch the first one when aiming for a convenient commercial diet, since that doesn't move. The commercial stuff does smell strongly, regardless of the brand, or whether it's designed for aquatic turtles, tortoises, box turtles, or even fish. Still, it all smells very different than the natural protein sources, and the turtles will have to get used to the difference. That normally means, the turtles will have to get "starved" to the difference, as they don't always experiment untill they have to.
>>
The Boxies I offered the Mazuri to were far from starved. As to the odor... have you smelled it? It does not have a strong odor or taste.
>>As for the commercial food, most of what's on the market now will make most turtles grow well. An important factor is that the nutrition is fully lab-manipulated. Most of the bulk content is ground corn, soy, or puree of various warm-blooded vertebrates, with the nutrition coming from coerced compounds specifically included for that purpose. The drawback of the bulk items is that they are indeed unnatural, and, since most animal protein comes from vertebrates, often birds and mammals, the fat content can be unorthodox for a box turtle diet. Should an animal seem to be putting on excess weight, switching from a "turtle" pellet to a "tortoise" pellet (far less fat due to little animal ingredient) can prove helpful. I've used that route with multiple aquatic species in which the females in particular are prone to becoming overweight.
>>
Most of the bulk of the prepared diets that I use consist of dietary fiber... grain hulls. Also, no animal fat is added at all.
>>If there is one principle drawback to commercial food, the fat is it. Unlike with dog food and cat food, there are no weight-conscious turtle diets. Since most diets contain much beef, porcine or at least poultry by-product, excess fat can prove the error in commercial diets. The problem is not insufficient nutrition, but rather, too much of one part. It is unfortunate that there is not yet a turtle diet in which the protein is based on insect-derived matter or simply a higher-protein soy derivative.
>>
You want to explain the difference between a soy based protein (which btw is a minor component of grain based diets) and animal protein (which I can't name a single grain based diet which uses animal protein).
>>When large numbers of turtles are maintained, a prepared diet can prove a near-necessity for supplying the bulk of the diet. This is possible because many turtle species, including box turtles, are adaptable generalists. And this is fine. It should not, however, cut out all natural food from the diet. Natural food proves a crucial precursor for certain natural behavior. If only there were a practical way to provide a 100% earthworm diet for multiple animals, then perhaps we could say that a single food item would work for box turtles without any error...
This is the first thing you said in this post that's made a little sense to me.
