Nice one Wayne!! (pic)
I would like to know that this study of uv lights etc who's monitors was it carried out on, zoos usually take blood tests regularly & i'm not sure that the ones that rely on human generated lighting are as fit as some of the wild monitors or captive monitors been offered 160f basking sites & good background temps.
I'm sure this would make a difference on the result, there's no way i could take blood tests off my Lenny without stressing the hell out of him & upsetting his routines etc.
I can only offer short time results, but taking a 16" argus monitor to over 4 foot in 8 months with no uv exposure most tell you something, i do use vitd & pure calcium on & off depending on growth rate. Many good experience reliable keepers have told me provide a good basking site & you won't have a problem!!
Now for food, food is mass produced nowadays & power fed to make them efficient for business purposes, with this in mind i wouldn't dare stop feeding added vitamins to my argus. I do use natural food, but even trout is forced grown to make them cheaper to produce.
I just don't think they are as good quality food as animals/fish grown at a natural speed.
but again if you can fit uv in & want it crack on with it!!
