The Effect of Adding A Mix of L.Carnitine With Herbal Methionine And Sunflower Seed oil on The Production Characteristics of Broilers

Abstract

The study was conducted in the poultry field of the animal production department, college of agriculture, Kirkuk university from 1/12/2021 to 12/1/2022. The objective of the study was to evaluate the addition of L.carnitine with methionine and sunflower seeds oil to the broiler’s diet and its effect on their productivity. At age a day, 350 asexual broilers type Ross with an average weight of 42 gm were brought from (Kirkuk hatcher) in Kirkuk province. They were raised on a sawdust floor in a closed chamber with the use of 35 cages (dimension 190 x 90 cm), each chamber was equipped with two air pullers. Chicks were randomly assigned to 5 treatments with 5 replicates for each treatment (10 chicks per replicate). The result of statistical analysis showed that at week six of age (1-42 days) the body weight and the average weight gain of treatments 3, 4, and 5 differed significantly (P≤0.05) compared to treatments 1 and 2. The feed consumption rate was significantly lower in treatments 4 and 5 compared to treatments 1, 2, and 3, while the rate of feed conversion factor was significantly improved in treatments 3, 4, and 5 compared to treatments 1 and 2. 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. There was no significant effect on the relative weight ratio of breast, leg, wing, neck, back, and drumstick between the treatments as well as the carcass composition.
