The plasma concentration of 25-hydroxycholecalciferol was measured in 13 adult Hermann's tortoises (Testudo hermanni), seven adult spur-thighed tortoises (Testudo graeca) and two adult marginated tortoises (Testudo marginata) during 2004. They were healthy, of both sexes, and kept in captivity under natural unfiltered sunlight in southern England with no dietary sources of cholecalciferol. Blood samples were taken in March, June and August, and the concentration of 25-hydroxycholecalciferol did…

Comparison of total calcium, ionised calcium and albumin concentrations in the plasma of captive tortoises (Testudo species)
TLDR
Total calcium levels were a poor indication of ionised calcium levels, which constituted between 18 and 57 per cent of the total calcium value, and albumin values did not appear significantly affected by season.
Plasma 25-hydroxyvitamin D(3) concentrations in Hermann's tortoises (Testudo hermanni) exposed to natural sunlight and two artificial ultraviolet radiation sources.
TLDR
Exposure to sunlight at a latitude similar to that of the natural geographic range is recommended for healthy and calcium-deficient tortoises and plasma 25-hydroxyvitamin D(3) concentrations differed between Tortoises exposed to sunlight and those exposed to artificial UVB sources.
Analyse der Ernährung und der Haltungsbedingungen von in Deutschland gehaltenen paläarktischen Landschildkröten (Testudo spp.)
TLDR
The likelihood of tortoises developing pyramidal growth syndrome, which can be used as an indicator of the quality of tortoise husbandry, is high in animals kept in a terrarium and/or fed a diet of <80% grasses and weeds in summer and varies among species, with a higher incidence in Hermann’s tortoise (Testudo hermanni).
EVALUATION OF PLASMA 25-HYDROXYVITAMIN D, IONIZED CALCIUM, AND PARATHYROID HORMONE IN GREEN SEA TURTLES (CHELONIA MYDAS) EXPOSED TO DIFFERENT INTENSITIES OF ULTRAVIOLET B RADIATION.
TLDR
UVB exposure is an important source of 25-hydroxyvitamin D for green sea turtles and has significant effects on calcium metabolism in this species, suggesting that current mammalian-based PTH assays are not valid for reptiles.

Comparison of Ionized Calcium, Parathyroid Hormone, and 25-Hydroxyvitamin D in Rehabilitating and Healthy Wild Green Sea Turtles (Chelonia mydas)
TLDR
Calcium and iCa values were significantly lower and PTH and P were significantly higher in turtles in rehabilitation than in wild turtles, suggesting that dietary requirements are not being met in the captive population.

Lack of Association between Exposure to Natural Sunlight and Dental Disease in French Companion Rabbits
TLDR
Dental disease is undoubtedly among the most common conditions of companion rabbits, with a reported prevalence ranging from 12.2% to 38.1% and possible causes include metabolic bone disease associated with calcium and/or vitamin D deficiencies, vitamin D excess, genetic or congenital factors, trauma, iatrogenic malocclusion and insufficient dental wear because of a lack of abrasive food.
Metabolic bone disease in reptiles: Part 2
TLDR
Treatment will involve both stabilising the reptile and correcting underlying husbandry and dietary factors and calcium and vitamin D supplementation should be provided and supportive treatment is indicated.

Monitoring of Plasma 25-Hydroxyvitamin D Concentrations in Two Komodo Dragons, Varanus komodoensis: A Case Study
TLDR
It appears that in temperate climates, approximately 150 d of sun exposure combined with moderate amounts of dietary vitamin D3 may be adequate for Komodo dragons to develop and maintain appropriate circulating levels of 25-OH-D throughou...
Blood values in wild and captive Komodo dragons (Varanus komodoensis).
TLDR
The results indicate no notable medical, nutritional, or toxic problems in the wild Komodo dragon population and problems in captive specimens may relate to, and can be corrected by, husbandry measures such as regular ultraviolet-B exposure.
VITAMIN D STATUS OF WILD RICORD'S IGUANAS (CYCLURA RICORDII) AND CAPTIVE AND WILD RHINOCEROS IGUANAS (CYCLURA CORNUTA CORNUTA) IN THE DOMINICAN REPUBLIC
Abstract Calcidiol (25-hydroxyvitamin D) values are reported for 22 wild Ricord's iguanas (Cyclura ricordii) and seven wild rhinoceros iguanas (Cyclura cornuta cornuta). Calcitriol…
Evidence that 1,25-dihydroxyvitamin D3 inhibits the hepatic production of 25-hydroxyvitamin D in man.
TLDR
Evidence is provided that concomitant administration of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] would alter the response of serum 25-OHD to challenge with vitamin D and inhibits the hepatic synthesis of its precursor 25- OHD in man.
Regulation of cutaneous previtamin D3 photosynthesis in man: skin pigment is not an essential regulator.
TLDR
Increases either in skin melanin concentration or in latitude necessitated increases in the exposure time to simulated solar ultraviolet radiation required to maximize the formation, but not the total content, of previtamin D3.
Enzyme immunoassay for measuring 25-hydroxyvitamin D3 in serum.
TLDR
A rapid, competitive enzyme immunoassay for measuring 25-hydroxyvitamin D3 in serum based upon 25(OH)D3-3-hemisuccinate covalently coupled to secondary amino groups grafted onto the polystyrene surface of microtiter wells was developed.
Evaluation of Vitamin D Status in the Green Iguana ( Iguana iguana ): Oral Administration vs UVB Exposure
TLDR
This work states that long term feeding of vitamin D at 4,000 IU per kg of diet will produce signs of toxicity in some domestic animals, and milk is fortified with vitamin D to assure adequate intakes.

TLDR
The physiology of calcium metabolism in avian species is discussed along with common disease states arising from derangements in calcium homeostasis.

TLDR
Two studies were conducted to determine the suitability of the Westron Corp. self-ballasted mercury vapor lamps in the captive maintenance of the chuckwalla lizard, Sauromalus obesus, and found no significant differences in SVL and body mass growth rates, cloacal body temperatures or bone densities.
