Ctenosaura pectinata
This study was conducted to compare the growth patterns of black iguana (Ctenosaura pectinata) under captivity in two communities: Montecillo, State of Mexico (temperate weather) and Nisanda, Oaxaca (tropical weather). Two hundred and sixty black iguana newborns were included. In Montecillo, iguanas were fed a diet containing 16% to 22% crude protein (CP), and 13 to 25% neutral detergent fiber (NDF). In Nisanda, iguanas were fed with "tulipacho" (Hibiscus sp) containing 21.64% CP and 31.62% NDF. Variables analyzed included: body weight (g), snout-vent length (mm), total length (snout-tail, mm) and percent mortality. Growth parameters on each population were estimated with a sigmoid model. The average body weight after 761 d was greater (P<0.01) for the iguanas in Montecillo (232.0 g) than in Nisanda (30.2 g). Snout-vent length and total length variables were different (P<0.01) with values of 152.1 mm and 452.6 mm in Montecillo, vs. 90.1 mm and 204.0 mm in Nisanda, respectively. Mortality was higher (P<0.01) in Nisanda than in Montecillo (81.2% vs. 7.3%). It is concluded that growth patterns of black iguana under captivity are determined by proper management and nutrition systems, when and if adequate temperature is provided in the iguana's house.
