1. Use of dual-energy x-ray absorptiometry in non-ruminant nutrition research
ABSTRACT 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 inv
