Abstract

Three controlled experiments were conducted on captive white-tailed deer (Odocoileus virginianus) to determine the response of blood levels of nonesterified fatty acids (NEFA), individual ketone bodies, and cholesterol to differences in dietary energy intake. In two long-term experiments (>30 days), deer on restricted energy intake exhibited declining β-hydroxybutyrate levels over time that were usually lower than those of deer fed at a higher rate of energy intake. Deer fasted for 10 days had higher NEFA, cholesterol, and acetone and lower β-hydroxybutyrate concentrations than ad libitum-fed deer. Only β-hydroxybutyrate tended to vary consistently with dietary energy intake.
