In a previous study at VPI & SU, Servello (1981) developed a technique for predicting the digestible dry matter (DDM) and digestible energy (DE) of the diets of pine voles from a nutritive analysis of their stomach contents. In this nutritive analysis, developed by Goering and Van Soest (1970), feeds are divided into two major fractions: cell soluble and cell wall fractions. The cell soluble fraction is highly digestible while the cell wall (fiber) fraction varies in digestibility. It was found that the highly digestible cell soluble values of the stomach contents were the best predictor of the digestibility of the pine vole's diet. The objective of the present study was to use the cell soluble values of pine vole stomach contents to determine if there were seasonal or orchard differences in the diet digestibility of pine voles captured from diverse orchard habitat types.
