The objective of this study was to evaluate the effect of dietary conjugated linoleic acid (CLA) and false flax (Camelina sativa) seeds oil (FO), as a replacement for sunflower oil, on the performance of broiler chickens. Experiment was carried out on 96 chickens randomly divided into four groups – control: fed on the diet with sunflower oil (SO) and three experimental: fed on the diet with addition of CLA (2,86% starter, 4,32% grower) and fed on the diet with addition of CLA (1,43% starter, 2,16% grower) and SO or FO (1,43% starter, 2,16% grower). Daily weight gain, daily feed consumption, feed conversion ratio as well as final body weight were measured. No significant differences in growth performance were observed in the first period of experiment. In older birds dietary treatment with SO+CLA and FO+CLA daily weight gain, feed consumption and final body weight slightly increased. No significant differences in the values of analyzed parameters between SO, CLA and SO+CLA groups were observed. In conclusion, the results indicated that false flax oil and CLA can replace sunflower oil in chickens’ feeding, and demonstrated the effectiveness of false flax oil on the growth performance of broiler chickens.
