ヒ トの体 組 成測定 は,水 中体 重秤 量法 に代 表 され る 体 密 度 法 や 投 与 した重 水 の 希 釈率 に よる体 水 分 法 な ど,種 々 の方法 が提 唱 され て い る.近 年,生 体 の電 気 抵 抗 の大 きさが体 水 分 量 を反映 す る こ とを利 用 した測 定 法が 開発 され,米 国 を 中心 に 関連 の研 究報 告 が行 わ れて い る.こ の原理 に基づ く方法 としては,表 面 電極 に よって生体 の 電気 抵抗 を測 定す るイ ン ピー ダ ンス法 (Bioelectrical Impedance Analysis, BIA)と 全 身 を 磁 場 に暴 露 して 身 体 の 電 導 性 を 測 定 す るTOBEC (Total Body Electrical Conductivity)の2つ が あ る. イ ン ピー...
متن کاملPrediction of swine carcass composition by total body electrical conductivity (TOBEC).
An experiment was conducted to determine prediction equations that used readings for total body electrical conductivity (TOBEC) in the model for estimation of total fat-free lean and total fat weight in the pork carcass. Ultrasound measurements of live hogs were used to select 32 gilts that represented a range in weight, muscling, and fatness. The TOBEC readings were recorded on warm carcass si...
متن کاملTotal Body Electrical Conductivity (tobec) to Estimate Total Body Fat of Free-living Birds
Traditional methods to determine total body fat are undesirable under many circumstances because they require sacrificing individual birds. Walsberg (1988) recently introduced the total body electrical conductivity (TOBEC) method for total body fat to ecological studies. In this paper we expand on Walsberg’s (1988) seminal paper and show that: (1) TOBEC is accurate under a narrow array of body ...
متن کاملUsing Total Body Electrical Conductivity (TOBEC) and Optical Fat Probes for Estimating Carcass Composition
Current methods of pricing live animals do not adequately recognize differences in carcass composition and therefore do not adequately relate consumer demands to producers. Pricing systems based on carcass merit will be necessary before this relationship can exist. In order for carcass merit pricing systems to be accepted, methods to estimate carcass composition must be both accurate and object...
متن کاملEstimating Body Composition of Lizards from Total Body Electrical Conductivity and Total Body Water
Nondestructive methods of estimating body composition are crucial for measuring energy budgets of free-ranging animals. However, most methods have proved to be either difficult or inaccurate for estimating lipid mass, particularly in small animals. I validated the use of total body electrical conductivity (TOBEC) and total body water (TBW) to estimate lean mass and nonpolar lipid mass in the li...
