A meta-analysis was carried out in order to establish the energy requirements of adult cats. Publications that identified cat body weight (BW) were used to generate allometric relationships between energy requirements and BW of healthy adult cats, using log-log linear regression. Energy requirements were expressed in kcal/kg BW to be consistent with those reported by the National Research Council. Mean maintenance energy requirements were 55.1 (se 1.2) kcal/kg BW (115 treatment groups). Three allometric equations were identified to predict the energy requirements for maintenance of BW in the cat based on BW: light (53.7 kcal/kg BW- 1.061), normal (46.8 kcal/kg BW- 1.115) and heavy (131.8 kcal/kg BW- 0 .366). When reported on lean mass, the allometric equation revealed maintenance requirements were 58.4 kcal/kg lean mass- 1.140 (adjusted R2 0.694; thirty-six treatment groups). The present review suggests that values for maintenance energy requirements based on BW alone may not be an accurate prediction and more detailed information on the age, sex and neuter status, BW and composition would enhance the ability to interpret the maintenance energy requirements of cats.
进行了一项荟萃分析，以确定成年猫的能量需求。使用对数线性回归，从确定猫体重 (BW) 的出版物中生成健康成年猫的能量需求与 BW 之间的比例关系。能量需求以千卡/公斤 BW 表示，与国家研究委员会报告的一致。平均维持能量需求为 55.1（se 1.2）千卡/公斤 BW（115 个治疗组）。确定了三个比例关系方程，以根据 BW 预测猫 BW 维持的能量需求：轻（53.7 千卡/公斤 BW-1.061）、正常（46.8 千卡/公斤 BW-1.115）和重（131.8 千卡/公斤 BW-0.366）。当报告瘦体重时，比例关系方程显示维持需求为 58.4 千卡/公斤瘦体重-1.140（调整 R2 0.694；36 个治疗组）。本综述表明，仅基于 BW 的维持能量需求值可能不是准确的预测，更多关于年龄、性别和绝育状态、BW 和组成的详细信息将提高解释猫维持能量需求的能力。
