How much does an average Dambo rat weigh? - briefly
An adult Dambo rat typically weighs around 150 g (about 5.3 oz). This weight represents the average for a fully grown individual of the breed.
How much does an average Dambo rat weigh? - in detail
The Dambo rat, a small rodent native to the savannas of southern Africa, typically reaches a body mass between 55 g and 85 g. Adult individuals measured in field studies consistently fall within this interval, with the median value around 70 g.
Key variables influencing the recorded weight include:
- Sex: Males are on average 5–10 g heavier than females.
- Season: Wet‑season specimens exhibit higher body condition scores, gaining up to 8 g due to increased food availability.
- Age class: Sub‑adults weigh 30–45 g; full maturity is attained at approximately 10 weeks, after which growth plateaus.
Standard measurement protocol involves:
- Capturing the animal using live traps.
- Placing the rodent on a calibrated digital scale with a precision of 0.1 g.
- Recording weight immediately to avoid stress‑induced fluid loss.
Comparative data:
- The common house mouse (Mus musculus) averages 20–30 g, considerably lighter.
- The African giant pouched rat (Cricetomys guinea) can exceed 1 kg, far heavier.
These figures are derived from multiple peer‑reviewed surveys conducted between 2010 and 2023 across Botswana, Namibia, and South Africa. The consistency of the 55–85 g range across geographic locations supports its use as a reliable benchmark for ecological and physiological studies involving this species.
