Abstract
A biological experiment was conducted to study the effect of vitamin E and selenium
supplementation on growth performance and lipid profile with two hundred and ten commercial
straight run day-older layer chicks. The chicks were randomly allotted into seven treatment groups
with three replicates of ten chicks each. The chicks were fed basal diet (Ti), basal diet with 100mg/kg
vitamin E (T2 ), basal diet with 200mg/kg vitamin E (T3), basal diet with 0.2mg/kg selenium (T4), basal
diet with 0.4mg/kg selenium (T5), basal diet with 100mg/kg vitamin E plus 0.2mg/kg selenium (T6),
and basal diet with 200rng/kg vitamin E plus 0.4mg/kg selenium (T7) for thirty two weeks period. The
results revealed that there was no significant difference in body weight of layer chicks for the first four
weeks between treatment groups but the body weight of groups (T6 and T7) receiving both vitamin E
and selenium supplementation is significantly increased (P<0.05) during 5-32 weeks period of age.
The feed intake of layer chicks did not vary significantly between treatment groups. Chicks receiving
supplements of both vitamin E and selenium produced significantly (P<0.01) lower total cholesterol,
triglycerides, VLDL and LDL cholesterol and significantly higher (P<0.01) HDL cholesterol. Present
research suggested that vitamin E and selenium influences lipid metabolism by decreasing total
cholesterol, triglycerides, VLDL and LDL cholesterol and increasing HDL cholesterol.
