im currently feeding my sulcata elephant grass as a staple food.. is this okay, i also powder some d3 and sometimes give hibiscus flowers as a treat...
smoke_kush said:d3 is really bad for torts. It can actually intoxicate them. But a calcium supplement is a very good addition to a torts diet

maggie3fan said:I am not a dude...very much the woman actually...I have raised numerous tortoises with and without D3. My animals have to be inside here for 7 months thru the winter and they need the D-3 to carry them thru until the spring. They need D3 to help metabolize the food...but you shouldn't mix D3 and sunlight... you shouldn't mix D3 with UVB rays...

nrfitchett4 said:not sure about tort's, but for ig's dietary d3 is a no-no. their stomach doesn't do well processing it and it can cause illness.
a good rule of thumb is that any vitamin that is fat soluble can be overdosed. Why chance it when they can get it all from sunlight?

Vitamin D and Ultraviolet Light
Animals in their natural habitat are extremely unlikely to suffer hypovitaminosis-D3. Deficiencies are possible in captive animals which are deprived of access to sunlight or a suitable artificial U.V. source of sufficient intensity, e.g. True-lite @ (Durolite Corporation) or blacklight. Symptoms of deficiency include poor locomotion, osteomalacia and osteoporosis. Plant foods contain nil vitamin D3 [plants do contain ergocalciferol, otherwise known as. D2. -MK]. The skin of tortoises is however, extremely rich in oils containing sterols which react with UV to produces the vitamin and provided adequate UV exposure is attained oral supplementation is not necessary (Kauffield, 1969; Wagner, 1977). It is common for herpetologists to over estimate D3 demand and to grossly overdose orally. One possible consequence of this practice is metastatic mineralisation of the soft tissues (Barten, 1982; Wallach and Hoessle, 1966). Vitamin D3 is highly toxic and extreme caution should be exercised whenever oral supplementation is employed (Finlayson and Woods, 1977). If calcium and phosphorous are provided in suitable ratios and sufficient quantity and quality of UV are available, hypovitaminosis D3 is not at all likely. Human demand is for 10 micrograms (400iu) per day which can be obtained from as little as 3 hours exposure to sunlight. The requirements of tortoises are not known in detail, although Zwart (1987) suggest that 10-20,000 iu of D3 per Kg of general vitamin-mineral supplement dosed routinely at 4% food volume is an effective prophylactic measure where exposure to UV is inadequate.
I'm not sure what I did here but I cut in on another's post and didn't mean to. I was just reading it and had already replied...
