Geometric mean titer and standard deviation of FMD virus strains O, A and Asia 1 of adult cattle at day 0, 15 and 30 of parturitions (a, b and c) and Pasteurella multocida (d). Study includes seven groups: A, control; B, 45 days prepartum group without vitamin E and selenium supplementation; C, 45 days prepartum group with vitamin E and selenium supplementation; D, 60 days prepartum group without vitamin E and selenium supplementation; E, 60 days prepartum group with vitamin E and selenium supplementation; 45 days prepartum group with vitamin E and selenium supplementation; F, 75 days prepartum group without vitamin E and selenium supplementation; G, 75 days prepartum group with vitamin E and selenium supplementation. Highest antibody titer (p<0.05) was shown in group G in which VES was given along with vaccination 75 days before parturition. Very minimal antibodies were seen in control.
