Special Issue Information

Dear Colleagues,

The growth of human populations will lead to a significant increase in food production from both plant and animal sources. It is imperative to utilize growth promoters that enhance feed efficiency and reduce the costs required to meet this need. Although antibiotics have been commonly used for this purpose, their associated health risks, particularly the rise of antibiotic-resistant bacteria, make finding effective alternatives crucial. Consequently, there has been a substantial shift towards using probiotics, prebiotics, and synbiotics.

Probiotics are live microorganisms that, when administered in appropriate quantities, provide significant health benefits to the host. Prebiotics extend beyond carbohydrates to include various substances, such as polyphenols and polyunsaturated fatty acids, influencing areas beyond the digestive tract. Synbiotics effectively combine probiotics and prebiotics to have a positive synergistic impact.

The increasing number of studies conducted in this field confirm the growing consensus regarding the benefits of microorganism-based technology. However, critical questions remain regarding scientific principles, technological advancements, practical applications, and consumer safety.

This Special Issue requests original review/Research papers exploring multiple dimensions of probiotics, prebiotics, and synbiotics in ruminant and non-ruminant animals, including fish.

This review explores the role of probiotics in improving productivity and gut health in poultry through microbiome modulation, particularly during early life. Gut health is pivotal to poultry performance, influencing nutrient absorption, immune function, and disease resistance. Early-life interventions target the microbiome to shape long-term health and productivity. Probiotics, live microorganisms providing health benefits, improve gut health through the competitive exclusion of pathogens, immune modulation, antimicrobial compound production, and enhancing gut barrier integrity. Applying probiotics improves growth performance, feed conversion efficiency, body weight gain, and carcass quality by promoting lean muscle growth and reducing fat deposition. For laying hens, probiotics enhance egg production and quality. These benefits are linked to better nutrient utilization, a well-balanced microbiome, and reduced gastrointestinal disorders. However, the efficacy of probiotics depends on strain specificity, dosage, and administration methods. Factors like environmental conditions, storage stability, and interactions with other feed additives also influence their effectiveness. Despite these challenges, advancements in microbiome research and probiotic technologies, such as precision probiotics and synbiotics, provide promising solutions. Future research should focus on optimizing formulations, understanding host–microbiome interactions, and leveraging new technologies for targeted microbiome management. Full article

Salmonella infections in poultry production are a significant and pervasive concern, posing substantial risks to both animal and human health. This comprehensive literature review examines the current body of research on the use of various nutritional manipulations as a promising strategy to effectively control and mitigate the prevalence of Salmonella in poultry. The review covers a range of dietary interventions, particularly the utilization of probiotics, prebiotics, organic acids, and phytochemicals, and thoroughly evaluates their efficacy in reducing Salmonella colonization within poultry flocks. Furthermore, the review delves into the potential underlying mechanisms of action for these nutritional approaches to control Salmonella and the far-reaching implications for overall food safety. By providing a thorough analysis of the existing literature, this review aims to elucidate the most promising nutritional strategies that can be employed to control Salmonella in poultry production, ultimately safeguarding animal welfare and public health.
