This study was conducted in the animal field of the University of Anbar College of Agriculture from 15/December/2021 to 15/February/2022. Twelve Iraqi Awassi female lambs were used in the experiment, at ranged of ages 2-3 months with average body weight 16.737 kg. The experimental animals were randomly divided into three groups, each group consisted of four lambs. The first group (G1) was considered the control group and left without any treatment, while the second group (G2) was treated with omega-3 supplemented with vitamins A, D3 and E of 1.5 CC, whilst the third group (G3) was treated with vitamins A, D3 and E of 1.5 CC by intramuscular injection, the lambs were injected with 6 times, the interval between each injection was 15 days. The lambs were nourished on the same concentrated diet, alfalfa hay, minerals bloke and water given adliptum. The result showed that G2 had significant increased (P≤0.05) on glucose concentration level as comported with G1. G3 had significant increase (P≤0.05) in urea concentration level as comported with G1 and G2. G3 had significant increased (P≤0.05) in Cholesterol and Triglyceride concentration level as comported with G1and G2. G1 had significant increase in LDL concentration level as comported with G2 and G3. T1 had significant increase in AST in G1, G2 and G3 as comported with T2 and T3. In conclusion, that treat a lamb with vitamins A, E, D3 supplemented with omega3 and vitamins A, E, D3 (without omega -3) led to improve lipid profile, liver enzyme activity and public health of lambs.
