α,β,γ Within a column, means with different Greek superscripts are significantly different (P < 0.05); a,b,c within a row, means with different Latin superscripts are significantly different (P < 0.05). C = control feed; S5 = treatment with 50 g/kg of SOP; S9 = treatment with 90 g/kg of SOP.
¹Mean values with their standard errors (SEM); number of samples for each treatment at any time =3.
