Background The effects of nutraceuticals on the modulation of the intestinal microbiota are receiving increased attention however there are scarce number of studies investigating their effects in broiler meat production. The aim of this study was to implement feeding strategies and carry out a comprehensive trial on the interplay between carotenoids, anthocyanins, fructo-oligosaccharides, probiotics and gastrointestinal tract microbiota. Our feeding program was applied on an intensive production system with 1080 broiler Ross 308 flock.
Results We observed that nutraceuticals and synbiotics did not affect growth performance remarkably nevertheless, positive correlation was found between body weight and the beneficious Bacteroidales, Corynebacteriales and Pseudomonadales. Nutraceuticals were shown to boost broiler intestinal diversity and differentially enriched Lactobacillus, Enterococcus, Streptococcus and Escherichia-Shigella in core microbiome during the different stages of broiler rearing. Furthermore, diet supplemented with different nutraceuticals was shown to increase the number of unique beneficial bacteria (Faecalibacterium, Akkermansia).
Conclusion We concluded that nutraceutical-based feeding strategies can offer a promising, green approach for intensive poultry rearing by improving the health and production of livestock. We believe that the conversion of food industrial waste would result more sustainable bioactive component rich forages which invention could be implemented by other commercial antibiotic-free animal production system providing safe and quality meat.
