Estimation of body composition of pigs by a near-infrared interactance probe technique
Near-infrared (NIR) interactance was evaluated as a potentially new method for estimating live body and carcass composition of pigs. Using a surface placed fiber optic probe, measurements of the live animal and carcass were made on a total of 120 pigs. These measurements were compared with lipid and protein content of soft tissue dissected from the pig carcass. NIR results were evaluated using ...
متن کاملAn inexpensive method of determining body composition by underwater weighing.
A simple inexpensive densiometric method of determining body composition was compared to a more sophisticated one. Body density (Db), lean body mass (LBM), and relative fat content (%fat) were determined for 16 volunteers, 9 men and 7 women using a simple T-bar apparatus suspended in a swimming pool, and an electronic apparatus in conjunction with a metal tank. Residual volumes (RV) used in the...
متن کاملA new approach for the estimation of body composition: infrared interactance.
A new method for the estimation of body composition in humans, called infrared interactance, is discussed. Infrared interactance is based on the principles of light absorption, reflection, and near-infrared spectroscopy. Body composition (percentage fat) was estimated in 53 adults (23 to 65 yr of age) by infrared interactance and compared to results from deuterium oxide dilution (r = 0.94), ski...
متن کاملComparisons between fat measurements by dual-energy X-ray absorptiometry, magnetic resonance imaging and underwater weighing.
The assessment of fat proportion has received more attention and generated more different techniques than any other aspect of body composition, indicating its importance in nutrition studies, but also its difficulties. All in rivo methods have limitations and involve assumptions, not always fully appreciated. The assessment of accuracy is difficult, as the nearest to a reference technique is po...
متن کاملNear infrared spectroscopy for body fat sensing in neonates: quantitative analysis by GAMOS simulations
BACKGROUND Under-nutrition in neonates is closely linked to low body fat percentage. Undernourished neonates are exposed to immediate mortality as well as unwanted health impacts in their later life including obesity and hypertension. One potential low cost approach for obtaining direct measurements of body fat is near-infrared (NIR) interactance. The aims of this study were to model the effect...
