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.
Dr. Alain RIGGI, Global Poultry Manager at Phileo, highlights the main points of the poster "Effect of the dietary administration of premium yeast fractions on the productive performance of birds vaccinated against coccidiosis".

I. INTRODUCTION The importance of the microbiota and general gut health, in relation to animal health and thus performance, cannot be underestimated. This has led to the development of management tools to influence and support the gut microbiota, as well as gut health in general. Probiotics, defined by the FAO/WHO (2002) as “live microorganisms which when administered in adequate amounts confer a health benefit on the host”, are a good example thereof. Specifically...

The Problem Gut and oviduct microbiota are closely related, especially because of the common connection with the cloaca. In this condition, modulating the gut microbiota with multi-strain probiotic supplementation may change the oviduct tract microbiota. How we investigated or researched the problem Hyline W36 laying hens housed in commercial aviaries were evaluated. Control animals were fed the farm’s conventional diet. The 2nd treatment received the...

Introduction An increasing global population and food security needs have imposed a great pressure on poultry and livestock sectors to increase their production utilizing limited resources (1).Consequently, sub-therapeutic doses of antibiotics are being used widely in poultry as animal growth promoters and for prophylaxis (2). This is particularly true in low and middle income countries where poultry industries are playing an important role in their national economy...

CLINICAL AND SUBCLINICAL DISEASE Necrotic enteritis (NE) due to Clostridium perfringens is a disease of chickens (broilers, broiler breeders, commercial layers) and turkeys (Opengart and Songer, 2013). NE most often is diagnosed when it results in mortality and the presence of the gross lesion of a roughened-appearing mucosal surface of the small intestine at necropsy. However, the greatest economic loss to poultry producers may be due to the subclinical form of NE, which causes...

INTRODUCTION The United Nations estimates that there will be more than 9 billion people on the planet by the year 2050 (Roberts, 2011); thus, the world population will be 32% higher than that in 2006. In addition, the meat consumption per person per year is predicted to increase by 26% in the same period and will primarily comprise chicken consumption (FAO, 2010; OECD-FAO, 2010). Because of increasing concerns regarding antimicrobial resistance (Gadde et al., 2017b), growing...

INTRODUCTION With the introduction of selective media that could be routinely employed for isolation, Campylobacter was identified as a critical clinical pathogen associated with the gastrointestinal tract (GIT; On, 2001; Butzler, 2004). By the mid to late 1980s, Campylobacter had been recognized as one of the most common bacterial agents causing gastroenteritis worldwide (Allos, 2001; Domingues et al., 2012; Geissler et al., 2017). Currently, Campylobacter is considered one of...

In most regions, summer is around the corner and poultry farmers need to prepare the birds to combat the heat and hence stay productive. Adding a powerful yeast postbiotic can help broilers absorb nutrients more readily and keep cool. When the chicken is healthy and performing at its best, the bird is in a state of physiological equilibrium (homeostasis). When the animal is exposed to stressors, coming from external sources (such as heat stress) or internal sources (such as metabolic...

INTRODUCTION Currently, there is a major concern in the society with the use of antimicrobial agents in livestock feed, and such chemicals can be added to the feed as either therapeutic agents or performance enhancers. As enhancers, lower antimicrobial doses are used for longer periods, which can potentiate selection of resistant bacteria (Baurhoo et al., 2009). For this reason, a great pressure has been exerted by the society to reduce the use of antimicrobials in the...

Background Control and eradication of intestinal infections caused by protozoa are important biotechnological and medical challenges worldwide. The coccidial parasites Eimeria, Toxoplasma, Neospora and Cryptosporidium are the cause of serious diseases in humans and animals. Many of these intracellular protozoa affect the small intestine and produce devastating effects on immune compromised subjects [1-3]. These parasitic infections can cause a wide range of harm to the infected...

Probiotics are showing promise as antibiotic replacements but more scientific evidence is required to validate their beneficial effects. Previous broiler feed trials conducted with Bacillus amyloliquefaciens strain H57 (H57) indicated variable bird performance (Bajagai, 2018). In these trials, birds were kept under “optimal” experimental conditions, where most of stressors were absent from the environment. There is some evidence that probiotics are best applied when a bird or...
