In the fasted group, mean hydroxyproline: creatinine (OHP:C) was greater (<i>P</i>< 0.05) at week 4 compared to baseline at week 0. Between fasted deer and deer fed high protein-high energy (HPHE) and low protein-high energy (LPHE) diets, no difference in OHP:C ratios was detected during the initial 4 wk of the study. Urinary OHP:C ratios were significantly (<i>P</i>< 0.05) greater in the fasted group during refeeding, concomitant with greater feed consumption and weight gain. There was also a significant (<i>P</i>< 0.02) time effect in the fasted-refed group; OHP:C ratios increased during these two phases of the study. There was no difference between the HPHE and LPHE fed deer in renal OHP excretion. However, mean OHP:C ratios in yearlings (16.8 ± 2.2) were greater (<i>P</i><0.001) than in the adults (7.5 ± 1.2) of those groups, indicating a higher collagen turnover rate. Urinary OHP:C shows potential as an indicator of growth and starvation, and the data presented may serve as reference values.</p></div>
