Parameters	Dietary Groups ¹				SEM ²	p-Value
Parameters	T1	T2	T3	T4	SEM ²	p-Value
Live weight, g	2221.6 ^b	2347.9 ^a	2381.6 ^a	2369.1 ^a	31.52	0.008
Daily weight gain, g	62.22 ^b	65.75 ^a	66.71 ^a	66.35 ^a	1.17	0.009
Daily feed intake, g	93.76	89.80	90.93	91.11	1.08	0.129
Feed conversion ratio, g:g	1.51 ^a	1.36 b	1.36 ^b	1.37 ^b	0.01	<0.0001
Production efficiency index	421.6 ^b	491.3 ^a	499.6 ^a	493.1 ^a	8.88	<0.0001
Performance index	144.6 ^b	168.5 ^a	171.4 ^a	169.2 ^a	3.09	<0.0001

^a,b Superscripts above the averages for each parameter within rows express the significant difference (p < 0.05). ¹ Dietary groups (T1, T2, T3, and T4) were supplemented with Pulicaria jaubertii at levels of 0, 3, 6, and 9 g per kg of the basal diet. ² SEM = Standard error of means for groups effect.
