Probiotics and prebiotics in poultry nutrition
Under normal circumstances, there is a delicate balance of beneficial and pathogenic bacteria in the gastrointestinal tract (GIT). This is influenced by symbiotic and competitive interactions and relationships. The microbial communities will not only protect the GIT but also enhance productivity in the host. The use of probiotics and prebiotics are two approaches that have been examined and can potentially reduce enteric diseases in poultry and also enhance their productivity. These substances have been proposed to assist in the prevention of carcass contamination and improve the immune response in the chicken. Probiotics have been defined as 'a live microbial feed supplement which beneficially affects the host animal by improving its intestinal balance' (Fuller, 1989). The probiotic mode of action is by 'competitive exclusion', meaning there is competition for attachment sites in the GIT.
1. Introduction Chickens represent the most widespread source of animal protein that is acceptable for nearly all communities, and, not surprisingly, the highly efficient commercial production of chickens is practised daily worldwide. However, chickens also represent a reservoir of zoonotic agents like Salmonella or Campylobacter. Chickens in commercial production are hatched from disinfected eggs in a clean hatchery environment, despite Gallus gallus being evolved to hatch in...

Increasing prices and low availability of common feed raw materials resulted in the use of alternative ingredients in animal production. These ingredients are often characterised by a high amount of soluble fibre resulting in lower performance and intestinal health issues that limits their inclusion rate in the diet. Bacillus amyloliquefaciens CECT 5940 (Ba) is a probiotic that can produce various metabolites and enzymes relieving the negative effects of soluble fiber and therefore it allows...

INTRODUCTION: The gastrointestinal tract, often referred to as "the gut," is a complex system consisting of several components, including the epithelium, the immune arm, and the commensal bacteria. This intricate structure plays a crucial role in the overall health and well-being of animals. Understanding the defense mechanisms of the gut is vital for maintaining optimal gastrointestinal function and preventing the invasion of harmful pathogens. (Kogut et al .,...

Gut infections can be a major source of efficiency loss, downtime and additional costs for veterinary treatment. Microbiota stabilization is central to the health of the digestive system. By reinforcing the commensal microflora, probiotics help to combat stress and maintain good overall animal health. Aside from the positive effect on productivity, probiotics also help to improve animal welfare.

1. Introduction Coccidiosis is a parasitic disease caused by an apicomplexan parasite of the genus Eimeria, which infects different parts of the intestinal tract depending on the species of Eimeria [1]. Eimeria spp. invade intestinal cells and cause physical damage to the intestinal epithelium, producing hemorrhagic diarrhea and disrupting the normal functioning of the intestinal tract [2]. This leads to impaired nutrient absorption and compromised gut health [3]. On the other hand,...

Probiotics are included in the feed and administered continuously during the entire production cycle to maintain intestinal integrity and strengthen the immunity of the bird, thus reducing the need for repeated medication. Alternatively, water-soluble probiotics are often applied to quickly react to upcoming stress situations in the flock – but they can negatively impact the formation of biofilm in the water lines. For this reason, formulations that reduce the formation of biofilms...

INTRODUCTION Since the use of antibiotic growth promoters was banned by the EU on January 1st, 2006, several feed additives have been studied as alternatives to antibiotics, such as probiotics, prebiotics, synbiotics, and herbal medicines (1). Among these feed additives, prebiotics have been studied and supplemented broadly into broiler diets in recent years. Gibson and Roberfroid (2) defined a prebiotic compound as a non-digestible food ingredient utilized by intestinal microbiota....
