EFFECT OF VITAMIN E AND SELENIUM ON HAEMO-IMMUNO-BIOCHEMICAL PROFILE OF BROILERS

摘要

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 mgand 40 meg, 25 mg and 50 meg, 30 mg and 60 meg, 20 mg and 40 mcg, 25 mg and 50 meg, 30 mg and 60 meg, 0 in treatment groups T_1 to T_8 respectively. The vaccination of RD and IBD was done in treatment groups T_1, T_2, T_3 and T_4 while the groups T_5, T_6, T_7 and T_8 remains unvaccinated. The significant (P < 0.01) increase in TEC and heterophil and significant (P < 0.01) decrease in phosphorus level was seen in excess vitamin E and selenium treated groups. The humoral and cell mediated immune responsewas 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.
