| Abstract | ||
| The study was conducted in the poultry field of the animal production department, college of agriculture, Kirkuk university from the 30th of Sep 2021 to the 1st of Nov 2021. The objective of the study was to evaluate the addition of L. Carnitine with Herbal methionine and sunflower seeds to the broiler’s diet and its effect on their productivity. At age a day, 350 broilers (Ross308) with an average weight of 42 gm. They were raised on a sawdust floor in a closed chamber with the use of 35 pen (dimension 190 x 90 cm), each chamber was equipped with two air pullers. Chicks were randomly assigned to 8 treatments with 4 replicates for each treatment (10 chicks per replicate). The result of statistical analysis showed that at 42 day of age the body weight of T 3, 4, 5, 6, 7, and 8 differed significantly (P≤0.05) compared to T1 and T2. The average daily gain of treatment 6 was higher significantly (P≤0.05) compared to treatments 3, 4, 5, 7, and 8. Also, treatments 3, 4, 5, 7, and 8 were higher than the control and treatment 2. The feed consumption rate was significantly lower in all treatments compared to the control, while T8 was higher than the other experiment treatment. Also, it has been noticed that T4 was significantly lower in feed consumption rate compared to treatments 1, 2, 3, 5, 6, and 7. The rate of feed conversion was significantly improved in treatments 4 and 8 compared to the other treatment. The abdominal fat was significantly lower in all treatments compared to treatments 1 and 2, whereas the relative weight ratio of heart, liver, and gizzard did not differ between the treatments. The carcass composition was significantly higher in treatments 6 and 8 compared to the other treatments. There was no significant effect on the relative weight ratio of breast, leg, wing, neck, back, and drumstick between the treatments | ||
