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.
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....

1. Introduction Campylobacter jejuni has been considered one of the leading causes of human gastrointestinal diseases worldwide, with outbreaks registered both in industrialized and developing countries [1]. Campylobacter spp. colonizes the avian gut in high concentrations with few or no clinical symptoms. Hence, it has been traditionally considered commensal, although a revision of this bacteria–host interaction has been recently proposed [2]. Upon interaction with avian...

Canada’s broiler chicken industry has taken great steps to reduce the use of antibiotics in production. Chicken Farmers of Canada successfully implemented a plan to remove both Category I and II antibiotics for preventive use from broiler feeds. There may be benefits from similar products for birds raised for egg production. Our research team has been involved in the evaluation of feed ingredients of marine origin. Seaweeds available off the Atlantic Coast of Canada were incorporated...

Xylo-oligosaccharides (XOS) are xylose-based oligomers, which have been described to affect the gut microflora, and gut function in chickens (Zhou et al., 2021). This, in turn, may have an impact on intestinal epithelial cell turnover, which accounts for a significant part of the energy of maintenance required by the gastrointestinal tract. The aim of this study was to evaluate the effect of dietary XOS on gut function and epithelial cell turnover in broiler chickens. It was hypothesized...

Coccidiosis is a disease with substantial economic impact (Muthamilselvan et al., 2016), particularly due to the push to ban anticoccidials. Vaccines are available but can be expensive, and are often implemented for free range and breeder flocks only. Thus, it is imperative to find effective nutritional alternatives to reduce the impact of coccidiosis on broiler chickens. The aim of this experiment was to determine if the nutritional strategies of post-pellet whole wheat (WW),...

Feed additives have a promising impact on broiler production in improving performance and reducing the incidence of diseases in the post-antibiotic era (Ayalew et al. 2022). However, there are limited data that illustrate the effect of feed additives on broiler performance under necrotic enteritis (NE) challenge. Therefore, this study was conducted to determine the impact of an enzyme (xylanase, 3000 U/kg) and a probiotic (Bacillus subtilis, 2.2 × 108 CFU/g) on growth performance and...

The effect of probiotics on animal performance is not consistent and may be impacted by multiple factors, such as dose, route of administration, disease stress, and management. We have previously examined the efficacy of the probiotic Bacillus amyloliquefaciens strain H57 (H57) in a disease stress model with subclinical necrotic enteritis (NE) (Shini et al., 2020); in the study only one dose of H57 (10 8 CFU/g feed) was used. The purpose of present study was to evaluate if the...

I. INTRODUCTION Growing concern over the use of antibiotics due to the rise in antimicrobial resistance and rising consumer demand for antibiotic-free products is increasingly becoming a challenge for poultry production. There is a need to identify natural and economical alternatives such as probiotics. The supplementation of probiotics as an antibiotic growth promoter (AGP) alternative in poultry production has the potential to improve poultry health, performance, growth, and feed...

I. Introduction Phytase enzymes are commonly used in the pig and poultry feed industry mainly to increase the availability of phosphorus (P) from plant ingredients. Additionally, phytase improves the availability of other nutrients such as Ca, digestible amino acids (AA), and energy (Dersjant4Li et al. 2015a) by facilitating breakdown of phytate P and thus negating its anti-nutritional effects on nutrient digestibility. Combination of Phytase with NSP enzymes has proven to be an...
