Bearded Dragon Welfare and UV-B Requirements

Bearded dragons are popular reptile pets whose welfare depends critically on UV-B provision, thermal gradients, and appropriate diet. Metabolic bone disease from inadequate UV-B is a widespread welfare problem.

Key Facts

Metabolic bone disease from inadequate UV-B affects thousands of pet bearded dragons annually
Basking temperatures of 40-42 degrees Celsius are required for normal digestion
UV-B bulbs degrade before visible light output drops - regular replacement is essential
Juvenile bearded dragons require insect protein; adults transition to predominantly vegetable diet

Welfare Considerations

Bearded dragon welfare requires daily UV-B exposure from appropriate bulbs (UVI 3-4 in basking zone), thermal gradients from basking zone to cool end, correct diet by age, and regular health monitoring. UV-B bulb replacement every 6 months prevents metabolic bone disease regardless of visible light output.

What You Can Do

Replace UV-B bulbs every 6 months even if they still produce visible light
Provide basking spots at 40-42 degrees Celsius with a cool end below 28 degrees
Research species diet requirements and adjust feeding as juveniles become adults
