The Influence of Fodder Additives in Feeds on the Production Performance and Egg Quality of Laying Quails

摘要

The research has been carried out on 99 laying quails, randomly distributed in 3 groups, each group consisting of 33 birds. Group 1 received the base diet supplemented with organic Selenium (Sel-Plex) 0.04% + BioMos 0.12%; group 2 received the base diet supplemented with organic Selenium (Sel-Plex) 0.04% + Actigen 0.08, while the control group received the base diet, with no fodder additives. The experimental period was 18 weeks (from 5 weeks to 23 weeks of age). Individual weighing of quails was carried out at the beginning, in the middle and the end of the experimental period. During the experiment, a number of indicators were recorded: body mass evolution, mortality rate, laying intensity, mean egg weight, feed consumption/egg, the weight of the main structural components of eggs and their proportion, egg defects, egg chemical composition and the main physical and morphological indicators of egg quality. The combined use of feed additives (Sel-Plex + Bio-Mos and Sel-Plex + Actigen) led to positive results that confirm the positive influence of these additives, when used in the nutrition of laying quails.
