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 x 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 no supplementation) were tested. Birds were transferred to four-tier cages for the trial. Each kilogram of the commercial diet included 224 g crude protein and 3,080 kcal metabolizable energy. The experiment lasted 21 days. Daily weight gain and gastrointestinal tract weight were statistically higher in the wood shavings and wood shavings + symbiotic-supplemented groups than in control group. Villi length was higher in the wood shavings + symbiotic and symbiotic-supplemented groups than in control and wood shavings groups. The wood shavings groups had longer villi than control group. Villi width was higher in wood shaving + symbiotic-supplemented groups compared with the other treatment groups. The litter system of wood shavings and symbiotic supplementation provide better growth performance to quail by developing their duodenum histomorphological parameters and digestive tract.
