“…The water:FFT ratio is considered to be constant in DXA and can be deemed a bias in some situations (Roubenoff et al, 1993). This issue is so important that it has been extensively studied in juvenile and adult humans with disorders/diseases that alter the water equilibrium in the body (Snead et al, 1993;Georgiou et al, 1997). The water:FFT ratio bias must be taken into account in studies in which changes in BW of animals are an important factor.…”

-Precise body composition measurements are essential in animal nutrition studies because the impact of treatments is evaluated based on changes in body weight and composition. Various indirect techniques for animal compositional evaluation have been developed and evaluated for applicability in animal nutrition studies. A fast, accurate, minimally invasive method that requires little input is considered the ideal for providing information about the animal. Measurements obtained by dual-energy x-ray absorptiometry (DXA) are highly correlated with those obtained by chemical analysis and dissection. The algorithms of DXA software partition the six chemical components of the body (lipids, water, proteins, carbohydrates, non-bone mineral, and bone mineral) into three compartments (total body mineral content, fat mass, and lean mass). Questions have been raised about how this partitioning affects the precision of the DXA method. In addition, the relationship between the DXA measurements and dissected carcass tissues is nonrepresentational of the relationship between DXA and chemical analysis. Furthermore, since DXA devices and their software were developed primarily for human medicine, they may not be fully adequate for animal evaluation. Calibration is required to obtain true values. The DXA method has some advantages and disadvantages that should be identified and controlled before calibration. Nonetheless, DXA is a valuable tool that provides precise, repeatable body composition measurements of live monogastric animals and their carcasses.

“…It is inexpensive and has a low re-test error (Chen et al, 2007). Its drawbacks are that the large equipment required precludes its use in field studies and that in patients with fluid management problems, the measurements can altered (Georgiou et al, 1997).…”

“…It was previously reported using DXA that the body weight loss because of hemodialysis is highly correlated with loss of lean tissue mass but not with body mineral content or fat tissue mass. 51 However, DXA also may be dependent on a stable fluid status to some extent. Indeed, a study by Woodrow et al 43 found no correlation between TBW and fat-free mass by DXA in ESRD patients.…”

Body fat measurements using ADP and DXA were correlated with those using BIA across a relatively wide range of body fat levels in adults with ESRD. However, BIA appeared to underestimate body fat and overestimate fat-free mass, possibly because of increased measurements of body water. Because ADP is convenient and does not use body water content in determination of body density and body composition, it has very good potential as a relatively new technique to estimate percent body fat in adults with ESRD.
