In iguanas, what vitamin deficiency causes demineralized bone as seen on radiographs?

In iguanas, a deficiency in Vitamin D3 leads to demineralized bone, which is a significant issue visible on radiographs. Vitamin D3 is crucial for the absorption of calcium from the gut and maintaining adequate calcium levels within the body. This vitamin plays a vital role in bone metabolism by promoting the mineralization of bone. When iguanas are deficient in Vitamin D3, their bones can become weak and prone to conditions such as metabolic bone disease, characterized by reduced bone density and the appearance of demineralization on radiographs.

This condition can lead to serious health issues, including fractures and deformities, underscoring the importance of proper nutritional management in these reptiles. Proper lighting, exposure to UVB radiation, and dietary intake are essential in preventing such deficiencies in pet iguanas.
