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.
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...

1. Introduction Mycotoxins are low molecular weight compounds produced as secondary metabolites by filamentous fungi contaminating crops in the field or warehouses when environmental conditions of temperature and humidity are adequate. These metabolites have no biochemical relevance to fungal growth or development, and they constitute a chemically and toxicologically heterogeneous group, which are together only because they can cause diseases, including death, to human beings...

Antibiotics in feed have been effective in controlling the prevalence of necrotic enteritis in broilers. However, the occurrence and severity of C. perfringens -induced necrotic enteritis has increased over the years due to the banning of the use of antibiotics in food-producing animals. Thus, the poultry industry is in urgent need of alternative strategies to prevent necrotic enteritis in broilers. Probiotics have become the ideal alternative to antibiotic growth promoters....

This study evaluated the effect of probiotics, a prebiotic and essential oil blend and their combination on the growth of Salmonella Enteritidis (SE) in a digestive assay mimicking three digestive compartments of the poultry digestive tract: crop, proventriculus, and intestine. A poultry commensal Lactobacillus reuteri (LR) and SE strain were utilized. The prebiotic product was included at 0.025% (w/w) and probiotic product, a combination of 3 strains of Bacillus ...

Swine dysentery (SD) caused by Brachyspira hyodysenteriae is a highly contagious disease of grower and finisher pigs. SD causes severe mucohemorrhagic diarrhea, resulting in decreased feed efficiency and increased morbidity. Necrotic enteritis (NE) caused by Clostridium perfringens is characterized by high mortality in poultry with bloody diarrhea, and sudden death. B. subtilis and B. licheniformis have been identified from the gastrointestinal tract of...
