Animal and Environmental Health

Researchers from around the world trust RJL Quantum Analyzers to provide safe, reliable and accurate data for studies of all kinds.  Measures of body fat, fat free mass, intracellular water, extracellular water, total body water, and more, have been gathered and utilized on horses, cows, cats, dogs, sheep, bear and fish, just to name a few.

RJL Systems also specializes in custom engineering of Quantum technology to meet unique needs and environmental factors, like one of its current applications researching thousands of fish of various species.  BIA is also being used by the National Oceanic and Atmospheric Administration (NOAA) to assess the energy density and composition of fish from the Arctic Ocean to the Gulf of Mexico.

RJL BIA measures health markers in the Norwegian Arctic.

Researcher Jon Aars, pictured here in the Norwegian Arctic, utilizes RJL BIA to measure fat percentage changes in adult polar bears, and environmental factors related to hibernation.

Veterinarians are using Quantum Analyzers to determine the specific fat weight of dogs and cats in their practices.  Others monitor the total body water, intracellular water and extracellular water levels of horses[1].

N.S. Latman Ph.D (West Texas A & M University) applied a BIA to deceased cattle, to help predict salable yield and trimmable fat weight, to possibly help justify its sale on an individual merit basis.

Marty Marchello Ph.D, a North Dakota State University range scientist, utilized BIA technology to determine how various feeds and grazing affected body fat levels of cows, sheep and pigs.  H. Lukaski at the USDA in Grand Forks ND also helped refine the measurement by measuring large animal body fat with DEXA.
