Food Intake and Assimilation by Bobcats Under Laboratory Conditions

Frank B. Galley, George A. Petrides, Ernest L. Rauber, and James H. Jenkins



Energy balance in the wild bobcat (Lynx rufus) was measured on eight animals trapped in the field and maintained on chicken, rabbit (Sylvilagus floridanus), or deer (Odocoileus virginianus) meat diets for up to 100 days.  Food intake was found to be subject to much variation, with physical condition (as indicated by behavior, coat condition, and body weight) being maintained on an intake level of one-half the average intake.  Energy consumption averaged 138 kcal/kg/day.  Percentages of intake energy were as follows:  feces, 9 percent; urine, 8 percent; weight gain, 6 percent; and metabolism, 77 percent.  There are implications in these observations to understanding the life history of a carnivore.
