Urinary 3-methylhistidine and Progressive Winter Undernutrition in White-tailed Deer

Figure Legend


Fig. 1. Mean (± SE) urinary 3-methylhistidine:creatinine ratios (µmol:mg) of control and experimental white-tailed deer fed ad libitum and severely restricted amounts of a low protein-low energy commercial diet, Grand Rapids, Minnesota, 4 February to 5 May 1988. (Sample sizes were 3 and 4 for the control and experimental groups, except where indicated in parentheses.)

Fig. 2. Predicted values (solid line) of urinary 3-methylhistidine:creatinine (µmol:mg; + 90% confidence limits; broken lines) based on observed cumulative mass loss of seven adult white-tailed deer that consumed varying amounts of a low protein-low energy commercial diet, Grand Rapids, Minnesota, 4 February to 5 May 1988. (Open circles are observed values of controls; solid circles are observed values of nutritionally restricted deer; solid triangle is an outlier value [see Results]).

Fig. 3. Relationship of urinary 3-methylhistidine:creatinine ratios (µmol:mg) with urinary urea nitrogen:creatinine ratios (mg:mg) of seven adult white-tailed deer that consumed varying amounts of a low protein-low energy commercial diet, Grand Rapids, Minnesota, 4 February to 5 May 1988 (urea nitrogen:creatinine data from DelGiudice et al. 1994a).
