The interest in employing cell components as well as metabolites obtained from varied probiotic strains is increasing because of the growing concern regarding safety issues related to live microbial cells. Numerous benefits over conventional probiotics will facilitate the implementation of postbiotics as feed supplements in poultry nutrition. The beneficial characteristics, such as immunomodulation and antibacterial action, point to the possibility of postbiotics improving host health by altering the physiology of the host and ameliorating the disease condition in poultry. As we proceed forward with the ultimate aim of lowering antibiotic use in poultry, maximising performance and maintaining poultry production will be reliant on the best mixes of diverse alternatives as postbiotics, together with appropriate farm management practices. Trials with emphasis on validating the health claims made by these bioactive compounds are highly necessary. Furthermore, the employment of postbiotics under challenging conditions in poultry needs to be explored. This review focuses on highlighting the aspects about postbiotics and its various biological effects on meat and egg production in the poultry industry.
