EFFECT OF VITAMIN E AND SELENIUM ON HAEMO-IMMUNOBIOCHEMICAL PROFILE OF BROILERS

One hundred ninety two day old broiler chicks, randomly distributed into eight groups of two
replications in each were reared upto 6 weeks on standard managemental conditions. The powder
of vitamin E and selenium was added to the basal diet @ 0, 20 mg and 40 mcg, 25 mg and 50 mcg, 30
mg and 60 mcg, 20 mg and 40 mcg, 25 mg and 50 mcg, 30 mg and 60 mcg, 0 in treatment groups T1
to T8 respectively. The vaccination of RD and IBD was done in treatment groups T1, T2, T3 and T4
while the groups T5, T6, T7 and T8 remains unvaccinated. The significant (P < 0.01) increase in TEC
and heterophil and significant (P 0.01) decrease in phosphorus levl was seen in excess vitamin E
and selenium treated groups. The humoral and cell mediated immune response was higher in
vaccinated groups, which were supplemented with excess vitamin E and selenium than control and
non-vaccinated groups. It was concluded that the supplementation of vitamin E and selenium in diet
improves immuno status of broilers.
