Serum lipid levels were measured in 66 healthy sloth bears (Melursus ursinus ursinus) living under semicaptive conditions with access to natural food resources in the Bannerghatta Biological Park (Karnataka, India), a portion of their native habitat range in the Indian peninsula. Total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein cholesterol levels were analyzed. The effects of age, body weight, and season on these lipid parameters were statistically evaluated. There were no correlations between age and any of the serum lipid parameters analyzed. Positive correlations of body weight to both triglyceride and HDL cholesterol levels in these bears were identified. In addition, seasonal trends in physiological serum lipid values, potentially due to variations in the sloth bear diet, were identified. Serum triglyceride levels were higher during postmonsoon season and cholesterol levels were higher during winter compared to other seasons. Serum lipid values obtained from sloth bears in this study were also compared to previously published data on other members of the family Ursidae. This is the first report of serum lipid values as a reference for sloth bears. These values can be used as sensitive predictors of overall health and nutritional status to aid in the captive management and feeding of these bears.
在印度卡纳塔克邦班纳加塔生物公园（印度半岛它们原生栖息地范围的一部分），对66只生活在半圈养条件下、可获取天然食物资源的健康懒熊（马来熊指名亚种）进行了血清脂质水平测量。分析了总胆固醇、甘油三酯、高密度脂蛋白（HDL）胆固醇和低密度脂蛋白胆固醇水平。对年龄、体重和季节对这些脂质参数的影响进行了统计学评估。年龄与所分析的任何血清脂质参数之间均无相关性。确定了这些熊的体重与甘油三酯和HDL胆固醇水平均呈正相关。此外，还确定了生理血清脂质值的季节性趋势，这可能是由于懒熊饮食的变化所致。与其他季节相比，季风后季节血清甘油三酯水平较高，冬季胆固醇水平较高。本研究中懒熊的血清脂质值还与先前发表的关于熊科其他成员的数据进行了比较。这是关于懒熊血清脂质值作为参考的首次报告。这些值可作为整体健康和营养状况的敏感预测指标，以帮助对这些熊进行圈养管理和饲养。
