This experiment was carried out at the animal house, College of Veterinary Medicine / University of Kufa to find out the cholesterol concentration of blood and meat, dressing percentage with and without giblets, and relative weight of the heart, liver, and gizzard of pigeons administrated orally 1 ml/fish oil/bird daily. Thirty adult male pigeons (Zigil breed) were randomly divided into two equal treated groups as the following: T1/ birds without fish oil supplementation (control group) while T2/ birds were supplemented daily with 1 ml fish oil during the experimental period (30th days). Blood samples were collected at three times (0, 15th and 30th days respectively) during the experimental period. Serum cholesterol analysis of three times and Carcass parameters were measured at the end of the experiment. The results indicate that fish oil has a significant improving in blood cholesterol, the relative weight of liver and meat cholesterol. In conclusion, using fish oil during the breeding period may cause a significant decrement of blood and meat cholesterol to give healthy meat with the best effect on performance.
