Data on captive diets for black-and-white ruffed lemurs (Varecia variegata) are limited. Information on food items used, inclusion amounts, and the chemical composition of diets is needed to improve the management of nutrition-related health problems seen in captive lemurs (e.g., obesity) that have not been reported in their wild counterparts. To determine the ingredient and nutrient composition of diets for captive V. variegata, U.S. zoological institutions were surveyed. Chemical composition of reported diets was estimated using Nutritionist Pro™ (Axxya Systems, Stafford, Texas 77477, USA), and these values were compared numerically to wild lemur diets from the literature. Institutions included from six to greater than 30 different ingredients in their diets, including fruits (0.0-84.1%), vegetables (7.5-70.0%), greens (1.0-28.5%), and commercially available feeds (1.5-68.6%). Nutrient concentrations of captive diets ranged as follows: dry matter (DM), 14.5-67.6%; organic matter, 93.1-97.2% DM basis (DMB); crude protein, 7.9-23.9% DMB; fat, 2.0-6.5% DMB; total dietary fiber, 10.1-28.1% DMB; and N-free extract, 38.9-74.4% DMB. Captive diets had lower fat and total dietary fiber and higher protein and N-free extract compared to wild fruit items from Madagascar. Reducing the amount of fruit in captive diets for V. variegata would be expected to decrease digestible carbohydrate content and increase fiber content of these diets, which has implications for the prevalence of obesity in captive animals.
关于圈养黑白领狐猴（Varecia variegata）饮食的数据有限。需要有关所使用食物种类、添加量以及饮食化学成分的信息，以改善圈养狐猴中出现的与营养相关健康问题（如肥胖）的管理，而这些问题在野生狐猴中并未有报道。为了确定圈养黑白领狐猴饮食的成分和营养成分，对美国动物园机构进行了调查。使用Nutritionist Pro™（Axxya Systems，美国得克萨斯州斯塔福德市77477）估算所报告饮食的化学成分，并将这些值与文献中野生狐猴的饮食进行数值比较。各机构的饮食包含6至30多种不同成分，包括水果（0.0 - 84.1%）、蔬菜（7.5 - 70.0%）、绿叶蔬菜（1.0 - 28.5%）和市售饲料（1.5 - 68.6%）。圈养饮食的营养成分含量范围如下：干物质（DM），14.5 - 67.6%；有机质，以干物质为基础（DMB）的93.1 - 97.2%；粗蛋白，以DMB计的7.9 - 23.9%；脂肪，以DMB计的2.0 - 6.5%；总膳食纤维，以DMB计的10.1 - 28.1%；以及无氮浸出物，以DMB计的38.9 - 74.4%。与来自马达加斯加的野生水果相比，请圈养黑白领狐猴的饮食脂肪和总膳食纤维含量较低，蛋白质和无氮浸出物含量较高。减少圈养黑白领狐猴饮食中的水果量预计会降低这些饮食的可消化碳水化合物含量并增加纤维含量，这对圈养动物肥胖症的患病率有影响。
