CONTROL DIET OF PEANUT MEAL AND CONTROL DIET OF ETHER- 
EXTRACTED COTTONSEED KERNELS 
The growth curves of the rats fed the control diets are given in figures 1 and 
2. The charts have been compared with 50 gm. body weight as a base line or 
arbitrary starting point, since weight rather than age was the criterion of com¬ 
parison. The average rate of growth for males and for females has also been

represents estimated average rate of growth from fewer observations than for unbroken line. Peaks 
on female growth curves labeled “ young ” represent weight fluctuation due to pregnancy an 1 birth of 
young. Broken line on curves of female rats represents hypothetical course of weight variation if 
pregnancy had not occurred 
Fig. 2.—Growth of male and female rats on ether-extracted cottonseed kernel diet. No. 213, 214, and 
215 were fed 30 per cent butter fat and the remainder 17 per cent butter fat. Broken line on one curve 
represents estimated weight if pregnancy had not occurred 
computed and is shown on the charts. The rate of growth was much faster 
than that usually recorded in the nutrition literature and seemed to be asso¬ 
ciated with the sturdiness of the rats and with the high protein diet. The 
rapidity of growth necessitated the selection of 10 days for each omit on the 
abscissa instead of the conventional 20-day period, in order to keep the growth 
curves in the neighborhood of the 45-degree line.
