The Risk of Metabolic Bone Disease (MBD) in Bushbabies
Bushbabies (Galagos) are small, nocturnal primates that have become increasingly popular as exotic pets. However, one of the most common and serious health issues they face when kept in captivity is Metabolic Bone Disease (MBD), also known as Nutritional Secondary Hyperparathyroidism.

What is Metabolic Bone Disease (MBD)?
MBD is a condition where the bones become weak, brittle, or deformed due to an imbalance of minerals in the body—specifically calcium and phosphorus—often linked to a deficiency in Vitamin D3.

Causes of MBD in Bushbabies
Improper Diet: This is the primary cause. In the wild, bushbabies eat a diverse diet of insects, tree gum, and small animals. In captivity, owners often feed them too much fruit or insects that are high in phosphorus but low in calcium (such as mealworms without calcium loading).
Calcium and Phosphorus Imbalance: A healthy diet requires a specific Calcium-to-Phosphorus ratio (ideally around 2:1). If there is too much phosphorus, the body draws calcium out of the bones to compensate, leading to bone depletion.
Lack of Vitamin D3: Vitamin D3 is essential for calcium absorption. Since bushbabies are nocturnal, they do not get much natural sunlight. Without proper UVB lighting or dietary supplementation, they cannot process the calcium they consume.
Common Symptoms
Weakness and Lethargy: The animal may be less active or unable to jump (which is their natural behavior).
Difficulty Walking or Shaking: Tremors, twitching, or a "wobbly" gait.
Bone Deformities: Swollen joints, a curved spine, or a "rubber jaw" (where the jaw becomes soft).
Fractures: Bones may break easily even from minor movements or small falls.
Stunted Growth: In young bushbabies, MBD leads to poor development and permanent physical disabilities.
Prevention and Care
Balanced Nutrition: Provide a diet that mimics their natural intake, including high-quality protein and gum arabic.
Supplements: Use calcium and Vitamin D3 supplements as recommended by an exotic pet veterinarian.
UVB Lighting: Ensure they have access to appropriate UVB lamps to help their bodies synthesize Vitamin D3 naturally.
Regular Check-ups: Because bushbabies are "prey animals," they tend to hide their symptoms until the disease is advanced. Regular X-rays and blood tests are crucial for early detection.
Conclusion
Metabolic Bone Disease is a painful and life-threatening condition, but it is entirely preventable with correct husbandry and nutrition. If you notice any signs of weakness or abnormal movement in your bushbaby, consult an exotic animal specialist immediately.
