Table 2.

Growth performance of rats, relative spleen weight and intumesce index of the groups fed Nigella sativa seeds (30 and 50 g/kg) and the control group.

Treatment groups	Weight gain (g)	Average food intake per week (g)	Feed conversion ratio (FCR)	Relative spleen weight (%)	Intumesce index
Control	23.00 ± 4.3^b	367.50 ± 34.5	17.39 ± 1.9^b	0.46 ± 0.02^b	0.02 ± 0.01^b
Sa30	37.10 ± 3.9^a	390.81 ± 32.4	10.86 ± 1.9^a	0.49 ± 0.01^b	0.04 ± 0.02^ab
Sa50	39.00 ± 2.5^a	460.60 ± 26.0	12.67 ± 1.1^a	0.60 ± 0.03^a	0.06 ± 0.01^a

The data are presented as the means ± SEs, n = 6 per group. Means within the same column with different superscript letters are significantly (P < 0.05) different according to one-way ANOVA followed by Duncan’s post hoc analysis. Sa30: group fed Nigella sativa at 30 g/kg diet; Sa50: group fed Nigella sativa at 30 g/kg diet.
