Estimating 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...

Seasonal changes of total body water and water intake in Shetland ponies measured by an isotope dilution technique.

Water is an essential nutrient necessary to support life, and adequate water supply is crucial for animal survival and productivity. The present study was designed to determine seasonal changes in the water metabolism of horses under outdoor conditions. Total body water (TBW) and total water intake (TWI) of 10 adult Shetland pony mares were estimated at monthly intervals for 14 mo by using the ...

Total body water and body composition in chronic peritoneal dialysis patients.

In this investigation, total body water (TBW) in ten chronic peritoneal dialysis patients was studied by deuterium (TBW-2H), skinfold thickness (TBW-ST), Watson formula (TBW-WA), 58% of body weight (TBW-58%), and bioelectrical impedance (TBW-BIA), and these results were compared with the reference oxygen18 (TBW-18O) method. We also analyzed the fat-free mass (FFM) by skinfold thickness (FFM-ST)...

Seasonal changes in body composition in Australian Rules footballers.

Anthropometric measurements were collected from a group of Australian Rules footballers at the start and end of the competitive season. Eighty-nine players were studied, drawn from a top level professional league team, a second level association team and an A-grade amateur association team. Changes in the physical profile of these players during the season were observed. A small but significant...
