Research was conducted in experiment, which comparing characteristics of two groups of Ross 308 chickens: the experimental group with 5% addition of linoleic acid and the control group without the addition of linoleic acid. There was significantly higher carcass yield (P≤0.05) in experimental group. There were no significant differences in weight of offal in our experiment. Weight of abdominal fat in the experimental group was significantly higher (P≤0.01). The weight of heart was a higher (P≤0.05) in experimental group than in the control group. The analysis of various tissues of the breast and the thigh was found a higher proportion of fat and skin from the breast part (P≤0.01), and a higher proportion of fat and skin from the thigh part (P≤0.01) in the experimental group. Chicken breast part in the experimental group had a significantly lower proportion of muscle (P≤0.01).
