Digestibility, feed efficiency, and the effect of sex were evaluated in black iguanas (Ctenosaura pectinata) using two commercial pellets (rabbit and chicken). The experiment was performed in 80 iguanas in a completely randomized design with a factorial arrangement 2×2 over 105 days. No differences were detected by food type in weight gain (chicken vs. rabbit: 121 vs. 154 mg/d) and daily intake (chicken vs. rabbit: 524 vs. 551 mg/d), but differences were detected (P<0.05) in feed conversion (chicken vs. rabbit: 6.45 vs. 4.47). Rabbit pellets showed higher digestibility than chicken food (P<0.01) in dry matter (59.8 vs. 41.4%) and NDF (55.4 vs. 43.6%), respectively. Sex had no effect in any of the variable responses. Black iguanas can be raised since 6 months old in captivity with commercial food designed for rabbit or broiler. No special physiological adaptations occur in black iguanas correlated with change in feeding habits during ontogeny.
使用两种商业颗粒饲料（兔粮和鸡粮）对黑鬣蜥（栉尾蜥属栉尾蜥）的消化率、饲料效率及性别影响进行了评估。实验采用完全随机设计，将80只鬣蜥按2×2析因安排进行了105天的实验。食物类型对体重增加（鸡粮组与兔粮组分别为121与154毫克/天）和每日摄入量（鸡粮组与兔粮组分别为524与551毫克/天）未检测到差异，但在饲料转化率上检测到差异（P<0.05）（鸡粮组与兔粮组分别为6.45与4.47）。兔粮在干物质（59.8%对41.4%）和中性洗涤纤维（55.4%对43.6%）方面的消化率高于鸡粮（P<0.01）。性别对任何变量反应均无影响。黑鬣蜥6个月大时即可在圈养环境中用专为兔子或肉鸡设计的商业饲料饲养。黑鬣蜥在个体发育过程中未出现与饮食习惯变化相关的特殊生理适应情况。
