Proximate analysis of the experimental diets (dry matter basis).

Proximate composition (g/100 g)	T1 (control)	T2 (5 g/kg diet)	T3 (10 g/kg diet)	T4 (20 g/kg diet)
Ash	9.73	9.61	9.96	9.66
Crude protein	31.35	31.21	32.38	32.97
Crude lipid	4.38	4.26	4.33	4.68
Crude fiber	4.23	4.42	4.72	4.54
NFE%a	50.28	50.48	48.59	48.13
GE (MJ/kg)b	17.78	17.73	17.71	17.91

^aNitrogen-free extract (NFE%) = 100 − (crude protein + crude lipid + ash + crude fiber).

^bGross energy (GE) calculated based on 23.6, 39.5, and 17.2 kJ/g protein, lipid, and carbohydrates, respectively.
