Abstract: The main goal of this project was to evaluate the effects of the deterioration of winter diet quality on the food preference and intake, time budget, body mass loss, muscle protein catabolism and survival of white-tailed deer fawns on Anticosti Island. We evaluated body condition with the monitoring of body mass and snow-urine analyses throughout winter. Although a diet richer in white spruce than that presently observed in nature contains more fibre and secondary plant compounds, this diet did not influence the activity budget, body mass loss, catabolism of body protein, measured with urine analyses, and survival of white-tailed deer fawns. However, fawns on a natural control diet decreased their forage intake over winter, while those on a poorer diet maintained a constant intake at a higher level than those on the control diet. Body mass at the onset of winter was critical for the winter survival of deer on Anticosti.
