Four weeks old male rats of Sparague-Dawley were divided into three dietary groups (15%, 20% and 25% of dietary protein levels), and each dietary groups was further divided into sedentary and exercising groups. While the sedentary group of rats were housed in individual small cages all day long, the exercising rats were subjected to all day running and swimming at 30minutes per day. The influence of dietary protein level on the growth rate was studied. After three weeks of experimental period, the following results were obtained: 1. The body weight of sedentary group was significantly lower at 15% level of dietary casein than at both 20% and 25% levels. However, there was no significant difference between three levels. 20% level of dietary casein observed to produce most favorable in influence on maximum growth rate among three kinds of diets. 2. The body weight of exercising group was significantly higher at 25% level of dietary casein than at both 15% and 20% levels. However, there was no significant difference between three levels. Growth rate was higher in sedentary than in exercising rats, but there was a tendency that the casein level of exercising rats was higher than of sedentary rats.
