Summary
>Progress in an evaluation of productivity in animal populations through the development of a new tracer technique is reported. The problem of administering Ca/sup 45/ in a form that would release the active element over a protacted period at a relatively uniform rate and allow enough of the isotope to be carried over from hen to chick so that the radioactivity can be detected in the offspring during the first fall after hatching was solved by the use of delayedreaction chemical combinations and mechanical retarders. The Ca/sup 45/ was converted to CaCO/sub 3/, CaC/sub 2/O/sub 4/, and Ca/sub 3/(P0/sub 4/ )/sub 2/ . These compounds were mixed with a lipoidal carrier (a cooking fat) and placed in gelatin capsules. The animal populations studied were pheasants, chickens, and rabbits. (M.C.G.)
