Circulating immune cells, % of total live cells	Control mean	SCFP1 mean	SEM	Treatment effect P-value	Time effect P-value	Treatment × Time interaction P-value
CD4 T cells	14.31	14.50	1.50	0.223	0.0002	0.246
CD8 T cells	7.32	6.89	0.39	0.581	<0.0001	0.298
γδ T cells	17.61	15.39	1.86	0.310	0.0006	0.943
Neutrophils	17.30	18.83	1.02	0.527	<0.0001	0.019
Monocytes	7.06	8.08	0.40	0.221	0.0027	0.738
NK cells	2.17	2.11	0.09	0.556	0.0184	0.939

¹Calves fed SCFP received 1 g/d SmartCare in milk and 5 g/d NutriTek top-dressed on the starter for 31 d.
