Table 5.

Body weight gain, food intake, and food utilization rate of rats treated with sericin extract for 90 days.

Sex	Dose (mg/kg)	Total body weight gain (g)	Total food intake (g)	Average food utilization rate (%)
Male	1000	489.6 ± 32.1	2604.2 ± 145.3	18.8 ± 1.0
	500	498.1 ± 31.6	2673.0 ± 168.4	18.7 ± 1.0
	250	511.1 ± 46.9	2669.3 ± 205.8	19.2 ± 0.6
	Control	497.5 ± 36.4	2701.7 ± 143.5	18.4 ± 0.8
Female	1000	230.7 ± 16.8	1798.0 ± 104.5	12.9 ± 0.9
	500	240.5 ± 17.6	1813.2 ± 113.5	13.3 ± 0.6
	250	236.2 ± 28.2	1823.2 ± 164.5	13.0 ± 0.7
	Control	238.9 ± 29.2	1852.4 ± 122.5	12.9 ± 1.1

Note: The values represent the mean ± standard deviation of 10 rats. Food utilization rate (%) = (total body weight gain/total food consumption) × 100%. The values of the treatment groups did not differ statistically from the control according to one-way ANOVA at p < 0.05.
