The aim of this paper was to observe and highlight the possible influence of prebiotics (BioMos and Actigen) and organic Selenium (Sel-Plex), administered in the feeds of laying quails, on the intestinal mucosa and the impact it has on the production and consumption performances of the laying quails. The research has been carried out on 132 laying quails, assigned to 4 groups, each group consisting of 33 birds; a control group fed with combined fodder without any additives and 3 experimental groups fed with additives supplemented fodders -Actigen (0.08%) in experimental group 1, Bio-Mos (0.12%) in experimental group 2 and organic Selenium (Sel-Plex -0.04%) in experimental group 3. The experimental period was 26 weeks (from the age of 6 weeks until the age of 32 weeks). The lying quails were individually weighted at the beginning, at the middle and at the end of the experimental period. The main histological investigations that were carried out at the end of the experimental period consisted of the determination of the villi height, microvilli height and the subsequent intestinal absorption surface; also the body mass evolution, laying intensity and feed conversion were monitored. The birds in all the groups were kept in the same rearing conditions, throughout the entire experimental period. The recorded results confirm the positive influence of the used prebiotics (Bio-Mos and Actigen) and organic Selenium (Sel-Plex) on the intestinal mucosa by increasing the nutrient absorption surface thus explaining the improvement of the production performances and feed conversion in all the experimental groups, compared to the control.

The research has been carried out on 66 laying quails, divided in 2 groups, 33 quails/group; a control group fed the base diet, without any additive, and an experimental group fed with organic Selenium (Sel-Plex, 0.04%) supplemented feeds. The experiment was carried out over a period of 26 weeks (from the 6th week of age until the 32nd week of age). The laying quails were individually weighted, at the beginning, the middle and the end of the experimental period. The following parameters were recorded: body mass evolution and survival rate, laying intensity, mean egg weight and the feed consumption for an egg. In order to determine the egg quality the following parameters of the main egg components were determined: weight and proportion of the main structural components of the egg, egg defects and the main morphological and physical indices of quality of eggs (format index, egg volume, specific weight, yolk index, egg white index, Haugh units). The results recorded confirm the positive influence of the organic Selenium on production performances in laying quails and on egg quality. [ABSTRACT FROM AUTHOR]

The research has carried out on 99 laying quails, divided in 3 groups, 33birds/group,The control group was fed the base diet, the first experimental group was fed the base diet supplemented with Bio-Mos Prebiotic, 0.12% and the 2nd experimental group was fed the base diet supplemented with Actigen Prebiotic, 0.08%,The experimental period was 26 weeks (from the 6th week of age until the 32nd week of age),The laying quails were individually weighted, at the beginning, the middle and the end of the experimental period,During the experiment the following indices were monitored: body mass evolution and survival rate, laying intensity, mean egg weight and the feed consumption/egg, weight of the main structural components of the eggs and their proportion, egg defects, chemical composition and the main morphological and physical parameters needed to assess the egg quality.
