ULTRASONIC FAT MEASUREMENT OF CAPTIVE YEARLING BULL MOOSE
The ability to measure fat thickness in live moose offers potential as an index of population condition. Consequently, we evaluated the feasibility of using portable real-time ultrasound to measure body fat in five captive yearling bull moose (Alces alces). The rump region of the bulls was scanned,...
