Abstract

The aim of this research was to evaluate the effectiveness of the use of hybrid rye in rations for broiler chickens. The study covered 160 chickens split into four equal groups [I (control), II, III, IV] and kept for 42 d. Rye was introduced into the above-mentioned diets as a partial substitute for maize in the following quantities: (I), no rye; (II), 5% rye in starter feed and 10% rye in grower and finisher feed; (III), 10% rye in starter feed and 20% rye in grower and finisher feed; (IV), 15% rye in starter feed and 30% rye in grower and finisher feed. During the 42 d rearing period, the most favourable body weight gain (P ≤ 0.05) and feed conversion ratio (P ≤ 0.01) were observed in chickens fed with rations containing the highest share of hybrid rye (group IV). The rye did not affect the dressing percentage and muscularity but diversified the fatness of birds. The muscles of chickens from group IV showed higher (P ≤ 0.01) red saturation and lower (P ≤ 0.01) yellow saturation and hue compared with the muscle of birds receiving diets with the lowest rye content (group I). The results of the study show that the inclusion of hybrid rye can be recommended in broiler chicken diets at a share of 15% in starter feed and 30% in grower and finisher feed, respectively.
