Abstract

This study was conducted in the poultry field of the Animal Production Department, College of
Agriculture, Kirkuk University from 30/9/2021 to 1/11/2021. The objective of the study was to evaluate
the addition of L. carnitine with methionine and sunflower seeds to the broiler’s diet and its effect on their
productivity. 350 new hatched, unsexed broiler chicks Ross-308, with an average weight 42 g, they were
brought from (Kirkuk hatchery) in Kirkuk province. Chicks were randomly distributed into to 8 treatments
with 4 replicates for each treatment (10 chicks per replicate). The result of statistical analysis showed that
the concentrations of cholesterol and triglyceride.in blood serum had significantly decreased (P≤0.05) in
the all treatments of feed additive compared with the control. T4 indicated a decrease in blood cholesterol
compared to the other treatments. In addition, T7 and T8 showed a decrease in triglyceride compared to
the other experiment treatments, while there were no differences between all treatments in blood glucose.
The results showed that the fifth treatment was higher in (HDL) High-Density Lipoprotein, (LDL) Low-
Density Lipoprotein, and (VLDL) very Low-Density Lipoprotein compared to other treatments
