Values are means ± SEM, n = 15 or 16 per strain. Diet influenced body weights and intakes of both strains combined; diet names with different letter superscripts indicate that they differed significantly from each other (P < 0.01). Over all diets combined, the B6 mice weighed slightly but significantly more than did the 129 mice [F(1, 178) = 25.5, P < 0.00001]. The 129 mice ate significantly more food than did the B6 mice [(g/d): F(1, 178) = 29.4, P < 0.00001; (kJ/d): F(1, 177) = 28.7, P < 0.00001].
Body weight = mean of body weight measurements collected at beginning and end of 16-d two-bottle test series.
Food intake = average of 4-d test with only water to drink.
Water intake = intake from both bottles in two-bottle test of water vs. water.
