Abstract In this study, 600 1-day-old Japanese quail chicks (Coturnix coturnix japonica) were used to investigate the effects of bacteriocin and organic acids on performance and intestinal histomorphology and microbiology. Chicks were allocated to 6 groups, i.e., control, Bac150 (150 mg/kg bacteriocin), Bac300 (300 mg/kg bacteriocin), OA (3 g/kg organic acid blend), Bac150+OA (150 mg/kg bacteriocin + 3 g/kg organic acid blend), and Bac300+OA (300 mg/kg bacteriocin + 3 g/kg organic acid blend) group. The trial lasted 35 days. At the end of the trial, a statistical increase was not observed in the performance parameters of chicks with feed additives. However, 300 mg/kg bacteriocin + 3 g/kg organic acid supplementation given together has been found to have more positive effects on intestinal microbiology and histomorphology (P < 0.05). Consequently, it is understood that the use of these feed additives together will achieve better results. Keywords Quail . Bacteriocin . Organic acid . Growth performance . Intestinal parameters
Introduction After the antibiotics were banned, the search for alternative additives to antibiotics has accelerated due to the increased concerns about the possibility that this may adversely affect the continuity of production and profitability as a result of losses that may occur in the performance of animals (Shen et al. 2014). Organic acids, one of the feed additives used in the nutrition of farm animals, are widely used especially in human food and also in animal feeds as protectors for the control of molds and other microorganisms (FEFANA 2014). However, it has been reported that bacteriocins, which are antimicrobial compounds in peptide or protein structure used for biological preservation of human foods for many years, may be used as an alternative to antibiotics for nutrition of farm animals because they have various useful properties such as modulation of digestive system microbiota population (Schyns et al. 2013). Therefore, this study aimed to evaluate

the effects of bacteriocin and organic acid on growth performance, intestine histomorphology, and microorganism count of quails.
Material and methods Birds, diets, and experimental design The experimental procedures described were approved by the Adnan Menderes University Animal Ethics Committee (64583101/2011/027). This study used 600 1-day-old Japanese quail chicks (Coturnix coturnix japonica) of mixed sex. Chicks were randomly allocated into six treatment groups of 100 chicks each. Each group was distributed into five replicates with 20 chicks per replicate. Chicks were fed a
