Fish Oil Individual or Combination with L-carnitine on Broiler lipid profile

This experiment was designed to study the influence of fish oil and l- carnitine and their combination on lipid profile of broilers Ross 308 chicks. One hundred fifty straight run 1-day -old chicks were distributed randomly into three equal groups, (50 birds/ treatment) with two replicates as following: 1) birds fed basal diet without any supplementation. 2) birds fed basal diet daily supplemented with 3% fish oil. 3) birds fed basal diet daily supplemented with 3% fish oil plus l-carnitine (50mg per Kg). All chicks received vaccine against Newcastle disease ND strain (B1) by spray at one day of age. Others vaccines of ND strain (Lasota) were administrated by drinking water at the age 10, 20, 30 days respectively. At the end of the experiment, blood samples collected then measured the lipid profile of chicks’ blood serum. The significant improving of triglyceride, cholesterol, and HDL results were observed T3 birds received fish oil 3% and l-carnitine (50mg per Kg) of at age 32 days. Triglyceride, cholesterol, VLDL, and LDL were decreased (P≤0.05) as compared with control. However, HDL was increased (P≤0.05) as compared with control. In conclusion, fish oil plus lcarnitine can be used with broiler ration at a level (3% fish oil and l-carnitine (50mg /Kg) could enhance lipid profile and health status of broilers.
