Figure 1. The effect of long-term feeding of control or soft pellets on (A) body weight and (B) 24-hour food intake. (A) Body weight of control- and soft-fed rats after being weaned at 4 wks, measured weekly. Initially, growth was rapid until 9 wks, after which the gain in body mass slowed. After 22 wks, body weight in the soft-fed group was significantly greater. (B) 24-hour food intake of control- and soft-fed rats was measured biweekly from 8 wks of age. The volume of food intake at each week was not different between the groups. The results are means ± SEM. n = 10 for both groups. *Significantly different from control group means at equivalent week (p < 0.05).
