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.
Steven Ricke, Professor and Director of the Center for Food Safety at the University of Arkansas, discussed the effect of prebiotics, probiotics and organic acids to control Salmonella and Campylobacter, as well as the relevance of biosecurity, during IPPE 2017....

The recently Africa swine fever outbreak in China has affected the swine production since the virus is fatal and there is no vaccine to control it. Thousands of animals were sacrificed to avoid transmission of the disease, but the market suffered a strong impact. Thus, the consumption of poultry meat has increased to meet the demand. To supply part of the swine meat market, the poultry production needs to achieve higher production together with meat quality and food safety. Considering...

As the global animal husbandry industry enters the post-antibiotic era, “gut microbiota” replacing antibiotics has become the current new topic of discussion in animal intestinal nutrition. There are over 400 different microbial organisms in the animal intestinal tract, which can be classified into pathogenic, neutral and beneficial bacteria, that influencing the physiological functions, for instance, digestive, metabolic, immunomodulation and energy conversion, etc. Lactic acid...

Introduction
A common human propensity is to regard all microorganisms as “harmful”, in particular, equating bacteria to pathogenic germs. Nothing could be further from the truth. The number of beneficial bacterial species far exceeds the number of pathogenic species and many of the known bacteria are in fact useful or even indispensable for the continued existence of life on Earth. Prokaryotic microorganisms are...

Bacillus amyloliquefaciens CECT 5940 (Ecobiol®) expresses quorum quenching activity
Suggested link
Conclusions The dietary inclusion of Bacillus amyloliquefacien s CECT 5940 (Ecobiol®), antibiotic growth promoter (AGP), or competitor probiotics ( Bacillus subtilis A, and B) significantly improved feed conversion, reduced footpad lesion and C. perfringens in ileum while providing better carcass yield compared to the challenge group without additives. Furthermore, uniformity of the body weight was significantly better in...

Introduction Distillers dried grains with solubles (DDGS) are by-products obtained during production of biofuels as renewable energy sources. During starch fermentation from cereal grains, ethanol and CO2 are produced; meanwhile, the remaining nutrients are concentrated in the DDGS fraction (Singh et al., 2005). Corn is the main cereal used in ethanol production in the United States; however, other grains such as wheat, barley, and sorghum are utilized in different regions of...

Introduction Widespread use of antibiotics as growth promoters in animal feed is suspected to be a major driving force for the development of antibiotic-resistant pathogens, which have become a critical public health concern worldwide. Enhancing host immunity and disease resistance by specifically boosting the synthesis of endogenous host defense peptides (HDPs) may represent a promising antibiotic alternativ-strategy. HDPs have been found in nearly all forms of life and play an...

Necrotic enteritis (NE) prevalently occurs in broilers aged from two to six weeks that mainly caused by Clostridium perfringens C. perfringens can rapidly proliferate and produce toxins in intestine that contribute to losses in productivity, raising mortality, and contamination products. A variety of approaches were explored to prevent the incidence of NE in poultry. Among these, probiotics shows promise as an alternative to antibiotics in inhibiting growth of...

Introduction Foodborne pathogens are widely diverse in nature and continue to be the major cause of global public health problems in both developed and developing countries. Among these pathogens is Salmonella, responsible for costs with medical care, loss of productivity and expenses with control by the food industry and, mainly, problems for the poultry industry (MAJOWICZ et al., 2010). The Enteric serotypes usually are the disease causative, such as aviary paratyphoid,...

Introduction Host defense peptides (HDPs), also known as antimicrobial peptides, are present in virtually all species of life and constitute a critical component of the innate immunity [1,2,3,4,5]. Defensins and cathelicidins represent two major families of HDPs in vertebrates [6,7,8,9,10,11]. While defensins are categorized by the presence of six conserved cysteine residues in the C-terminal mature sequence [6,7,8,11], all cathelicidins consist of a conserved cathelin domain in...
