ARTIFICIAL ULTRAVIOLET B RADIATION RAISES PLASMA 25-HYDROXYVITAMIN D

Area of Science:

• Herpetology
• Zoology
• Comparative Physiology

Background:

• Vitamin D deficiency is linked to metabolic bone disease in reptiles.
• UVb radiation's role in vitamin D3 synthesis in snakes has yielded inconsistent findings.
• Burmese pythons (Python bivittatus) require adequate vitamin D3 for bone health.

Purpose of the Study:

• To investigate the effect of high UVb irradiance on plasma vitamin D3 concentrations in Burmese pythons.
• To assess the potential of UVb exposure to improve vitamin D3 status in captive snakes.

Main Methods:

• Blood samples were collected from four Burmese pythons at baseline (day 0) and after 310 days.
• An Arcadia Superzoo T5 ASZ01 UVb lamp was installed in the python enclosure.
• Pythons were exposed to UVb radiation for a continuous period of 310 days.

Main Results:

• Plasma vitamin D3 concentrations were significantly higher in all pythons after 310 days of UVb exposure.
• The study demonstrated a positive correlation between prolonged UVb exposure and increased vitamin D3 levels.
• A 10-month period of UVb exposure effectively elevated vitamin D3 status in the studied Burmese pythons.

Conclusions:

• Sustained UVb exposure can enhance vitamin D3 status in Burmese pythons.
• This finding suggests UVb supplementation may be beneficial for captive reptiles.
• Further studies are required to determine the specific health benefits of elevated vitamin D3 levels in snakes.
