Supplementation of vitamin E and selenium in different diets on performance of IPB D-2 chicken during developer-layer period

Abstract

Supplementation of vitamin E and selenium improved the productivity of livestock. This study aims to evaluate the effect of vitamin E and selenium supplementation on different diets of IPB D-2 chickens during 15-21 weeks. Completely randomized factorial 2 x 2 (factor A was diet type and factor B was vitamin E supplementation) and five replications was used in this experiment. The variables observed were performance, blood profile, organ immunity and percentage of carcass weight. The results showed that diet type had a significant effect (P < 0.05) on feed consumption in the developer and layer periods and had a highly significant effect (P < 0.01) on feed consumption in the pre-layer period and body weight gain in the layer period. Vitamin E and selenium supplementation had a significant effect (P > 0.05) on pre-layer feed consumption. The blood profile was in normal range with optimal stress levels. There was significantly interaction (P < 0.05) between diet type and vitamin E supplementation on carcass percentage and highly significantly interaction (P < 0.01) on layer feed conversion. Parameters of immune organ and egg production were not affected by treatment. The diet type was reduced by 5% from the standard with supplementation vitamin E dan selenium showed the best result for IPB D-2 chicken performance.
