I. INTRODUCTIONPhytogenic products are used as an antibiotic alternative, with other alternatives like prebiotics, probiotics, organic acids and other products with antimicrobial properties. The ability of phytogens to reduce the load of significant pathogens such as Clostridium (2020), Escherichia (Zou et al., 2016), and Salmonella (Abudabos et al., 2016), and improve the health and performance o ...

I. IntroductionGlycans are polysaccharides, essential biomolecules with well-established benefits for the host and abundantly used as prebiotics to support balanced microbiome function. Host produced glycans, such as mucins, are crucial for the defensive purpose of the intestinal epithelial barrier against pathogens (Coker et al., 2021). Glycans are often projecting on the cell surface and are fre ...

The caecal microbiota composition of commercial broilers is essential to the poultry industry as it can affect the broiler’s health and performance (Pandit et al., 2018). Bioactive components of the Black Soldier Fly larvae (BSFL) include antimicrobial peptides, chitin, and lauric acid. They are known to modulate the immune system of broiler chickens (De Souza-Vilela et al., 2020). This stud ...

I. INTRODUCTIONOregano essential oil contains many compounds, of which carvacrol, thymol and their precursors are the major components, accounting for approximately 80% of the contents. Carvacrol and thymol have been shown to actively disrupt the cell membranes of bacteria leading to cell death, promoting the use of oregano as a phytobiotic (Rao et al., 2010). Phytoadditives such as oregano are be ...

I. INTRODUCTIONThroughout the world, poultry are a major and growing source of high-quality protein, as they outperform all other terrestrial meat production systems in water, feed, carbon, and land use efficiency. A challenge for intensive production systems has been the potential to introduce high pathogen loads and stresses on the animals. Such challenges have traditionally been managed with th ...

I. INTRODUCTION The recent major drop in the cost of DNA sequencing, combined with advances in the annotation of 16S rRNA gene microbial databases and analysis tools, have all contributed to the “golden age of microbial ecology” (Oakley et al., 2014). Poultry researchers have leveraged and applied these advances to define approaches that may be taken to manipulate microbiota to improv ...
