Abstract
ABSTRACT The objective of this study was to determine the effect of dietary symbiotic supplementation on the growth performance and duodenum histological parameters of quail reared in different flooring systems. A total of 160 mixed-sex healthy quail (47±0.32 g) aged 14 days were used in a 2 × 2 factorial experimental design with four replicates, each including five males and five females. Two flooring systems (wire floor as control and wood shavings bedding) and two dietary treatments (symbiotic supplementation and [...]

The ban on antibiotics as a growth factor in the European Union has led researchers to focus on natural feed additives such as prebiotics, probiotics, and symbiotics in animal nutrition (Genc et al, 2006; Ayasan, 2013; Hamasalim, 2016)

Weight gain was statistically higher in wood shavings and wood shavings + symbiotic supplementation groups than in control group (P
Summary
The ban on antibiotics as a growth factor in the European Union has led researchers to focus on natural feed additives such as prebiotics, probiotics, and symbiotics in animal nutrition (Genc et al, 2006; Ayasan, 2013; Hamasalim, 2016). Saccharomyces cerevisiae and its cell wall mannan oligosaccharides (MOS) and β-glucan are one such natural feed additive. It has been further reported that Saccharomyces cerevisiae (Nikpiran et al, 2013), MOS, (Markovicva et al, 2009), and β-glucan (Zhang et al, 2005; 2008) increased broiler performance and served as alternatives to antibiotic growth factors. By contrast, Ceylan and Ciftci (2003), Karaoglu and Durdag (2005), and Morales-López et al (2009) stated that Saccharomyces cerevisiae and MOS or a mixture of the two did not improve broiler performance, whereas Ozturk and Yildirim (2004) reported that the success of probiotics and prebiotics, or their mixture as a symbiotic, depends on genetic, environmental, and different stress conditions
