Growth of juvenile green iguanas (Iguana iguana) fed four diets.
Wild green iguanas consume a primarily folivorous diet. As pets in captivity, they suffer high mortality and malnutrition. Nutrient requirements are not established. The purpose of this study was to compare growth in juvenile iguanas fed three commercial diets and a romaine-based diet. Twelve nominally 4-wk-old iguanas were fed in a latin square design each of four diets for 8 wk, consisting of a 2-wk accommodation period and a 6-wk collection period. Diets were analyzed at the beginning and end of the study. Food consumption was measured daily; body weights and lengths were measured weekly. For Diets A, B, C and D mean body weight gains were--3, 6, 31 and 60% in 6 wk, respectively. Gain in body weight and snout-vent length increased linearly with dietary protein and fiber and with dry matter intake. The data suggest that growth in pet green iguanas may achieve rates for farmed and wild green iguanas when diets are palatable and contain adequate protein and fiber.
