Abstract


The research was performed on 135 broiler chickens, COBB 500 hybrid divided in 3 groups with 45 chickens/group during 42 days. The group 2 (E) received 0.02% organic selenium (Sel-Plex) in combined forage. The group 3 (E) received the prebiotic Bio-Mos in following proportions: 0.2% (phase I); 0.1% (phase II) and 0.05% (phase III). The chickens from all 3 experimental groups were weighted in the beginning of the experiment, weekly during the experiment, and in the end of the experiment. The following parameters were recorded: the evolution of the body weight, average daily gain, average daily consumption, specific consumption, commercial yield and meat share in different carcass qualities. The use of the organic selenium (Sel-Plex) in group 2 (E) and pre-biotic (Bio- Mos) in group 3 determined the increase of the body weight at delivery (42 days of age) by 7.14% in group L2 (E) and 7.26% in group L3 (E). The average daily gain increased by 7.25% and 7.38%. The specific consumption decreased by 4.24% in both experimental groups, compared to group L1-(M). The increase of the commercial yield by 1.48% in group L2 (E) compared to control and high quality meat share (Ist quality + IInd quality) in the same group by 1.39% compared to group 1 (M). The results confirm the favorable influence of the organic selenium (Sel-Plex) and pre-biotic (Bio-Mos) on main production and consumption indices and main slaughter indices in broiler chickens.
