The Influence of Some Prebiotics (Actigen, Bio-Mos) Administered in Laying Quails Feeds on Growth Performances and Egg Quality
Abstract
Introduction: Research carried out worldwide on laying quails showed that some prebiotics can have beneficial effects on production performances and egg quality.
Bio-Mos and Actigen, when administered in feeds, led to the improvement of egg production by increasing the laying frequency and the egg quality, with regard to their weight and composition.
Aims: The aim of this research was to highlight the possible influence of prebiotics (Bio-Mos and Actigen) administered in the feeds for lying quails on production performances and egg quality parameters.
Materials and methods: The research has been carried out on 99 laying quails, divided in 3 groups - 33 birds/groups. The control group was fed with the base diet, with no additive supplementation; the first experimental group was fed with Bio-Mos supplemented feeds (0.12%) and the second experimental was fed with Actigen supplemented feeds (0.08%). The experimental period was 26 weeks long (from the 5th week of age until the 31st week). The laying quails were weighted individually at the beginning, at the middle and at the end of the experiment. 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 mail structural components of the eggs and their proportion, egg defects, chemical composition and the main morphological and physical parameters needed to asses the egg quality.
Results: the use of prebiotics (Bio-Mos and Actigen) in the mentioned doses determined an increase of the laying frequency, egg weight and the reduction of the feed conversion ratio/egg due to the enlargement of the nutrient absorption area at the intestinal level. Also a reduction of egg defects could be noticed accompanied with the reduction of mortalities.
Conclusions: the results recorded after prebiotics (Bio-Mos and Actigen) administration confirm their positive effects on production performances and egg quality in laying quails.
