Fig. 2. Linear regressions (P $<=$ 0.01) of rumen escape N (g kg^-1 DM) on (A) heating degree days >35°C, (B) 30-d average temperature, and (C) maximum internal bale temperature. Data from 1998 are represented by ${diamondsuit}$ ; data from 1999 are represented by ${diamond}$ . In each case, intercepts associated with regression lines for 1998 and 1999 differed (P < 0.0001), but slopes did not (P $>=$ 0.416).
