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.
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,...
Surfactin is a powerful biosurfactant with significant potential in the livestock industry. It is renowned for its strong antimicrobial and anti-inflammatory properties, making it essential for enhancing animal gut health. By improving feed efficiency and boosting disease resistance, Surfactin plays a critical role...
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....
Rick Kleyn (Consultant at Spesfeed) explains the importance of proper management as a first step and how probiotics and enzymes play a role in keeping gut health, in this Engormix interview....
I. INTRODUCTION The increased recognition of antimicrobial resistance as a public health risk and, therefore, the imposed restrictions on the use of antimicrobial growth promoters (AGP), has driven the search for novel nutritional strategies for broiler chickens. The advances in molecular biology, analytics, and data science in the past years have enhanced our understating of the gastrointestinal tract (GIT) microbiome of chickens (Oakley et al., 2014; Sun et al., 2021). These novel...
I. INTRODUCTION Mycotoxins are secondary metabolites produced by fungi (fusarium, aspergillus, penicillium mainly) that can cause serious health problems in poultry and may result in severe economic losses. They can exert negative impact on both performance (Kolawole et al, 2020) and intestinal health (Antonissen et al, 2014) depending on the type of mycotoxin, extent of exposure, its concentration, the age of the animals and their health status. Mycotoxins can also be a predisposing...
I. INTRODUCTION The ban on the use of AGPs together with good antibiotic stewardship practices by intensive livestock industries resulting in a decline of antimicrobial resistance globally (Salim et al., 2018). Probiotics have been widely studied partially as a replacement of AGPs. Some probiotics are able to improve production performance whilst improving gut health and decreasing the likelihood of mortality due to infection. This study investigated the effects of various novel...

I. INTRODUCTION Continuous interest in new probiotics to alleviate intestinal health problems is emerging, especially since antibiotics become more restricted in use. Various Bacillus spp. are known to improve broiler performance and health due to their ability to produce antimicrobial substances, modulate the immune system, change the intestinal microbiota or increase nutrient digestion and utilization (Lee et al., 2010; Caulier et al., 2019; Giurescu et al., 2020; Jha et al., 2020;...

1. Introduction The digestive tract serves as a selective regulator of nutrient intake and is the site of interaction with commensal and pathogenic bacteria [1]. Pathogenic colonization of the gut has negative effects on enterocyte permeability, ion transport and the structure of the mucosa [2]. Campylobacter jejuni is considered responsible for several gastrointestinal diseases in humans, with high consumption of chicken meat and poultry products being associated with human...

Microsaf® is a unique association of three proprietary strains from 3 Bacillus species, carefully chosen to produce improvements in feed efficiency, gut function and microbiota, and overall growth performance in birds. The performance of Microsaf® is enhanced by Germination Optimization Technology (GO Technology®), a new process designed to promote faster and stronger Bacillus spore germination. ...
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...
