THE EFFECT OF AGE AND THE PLANE OF NUTRITION ON THE BLOOD CHEMISTRY OF THE COLUMBIAN BLACK-TAILED DEER (ODOCOILEUS HEMIONUS COLUMBIANUS): B. BLOOD GLUCOSE, NON-PROTEIN NITROGEN, TOTAL PLASMA PROTEIN, PLASMA ALBUMIN, GLOBULIN, AND FIBRINOGEN

Abstract

The blood sugar, non-protein nitrogen, total plasma protein, plasma albumin, globulin, and fibrinogen of the Columbian black-tailed deer have been studied on two series of animals reared on high and low planes of nutrition from birth to 465 days of age. Of these blood constituents only blood sugar and fibrinogen showed a measurable lowering in the low plane animals. Age changes have been noted that are independent of nutritive state but are similar to those reported for domestic ruminants.
