Felids are adapted to eat whole prey, but in North American zoos are usually fed processed diets based on muscle meat. We analyzed proximate nutrient composition and digestibility by ocelots of a commercial processed diet and whole animals of five species. The processed diet did not differ significantly from the whole animals in proximate composition, although it was at one end of the range of results for all nutrients. Domestic chicks were significantly lower than all other dietary items tested in digestibility of energy and fat, and lower than rabbits and quail in digestibility of dry matter. There were no other significant differences. These results suggest that the commercial diet tested provides an appropriate nutritional environment for ocelots with respect to proximate constituents. Studies of vitamin and mineral composition and digestibility and comparisons to wild prey species should be conducted to permit a full evaluation.
猫科动物适应于捕食完整的猎物,但在北美动物园中,它们通常被喂食以肌肉肉为基础的加工饲料。我们分析了一种商业加工饲料以及五种动物的完整尸体的近似营养成分和豹猫对其的消化率。加工饲料在近似成分上与完整动物并无显著差异,尽管它处于所有营养素结果范围的一端。家鸡在能量和脂肪消化率方面显著低于所有其他测试的食物项目,在干物质消化率方面低于兔子和鹌鹑。没有其他显著差异。这些结果表明,就近似成分而言,所测试的商业饲料为豹猫提供了适宜的营养环境。应该进行维生素和矿物质成分及消化率的研究,并与野生猎物物种进行比较,以便进行全面评估。
