Winter plants have lower protein and higher lignin, cellulose and hemicellulose concentrations compared with spring and summer. Data includes the average of insoluble fiber determined by sequential fiber analyses on primary plant species consumed across all seasons, with s.d. shown. Values are reported as a percent of dry matter that was remaining at each sequential step. Significant differences (P<0.05, students t-test) between spring and summer compared with winter is denoted by *, whereas significant differences between spring and summer are denoted by **.
