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 Plant materials including flowers, roots, bark, leaves, seeds, peel, fruits, and wood can be used to extract aromatic and volatile liquids known as essential oils (EOs) (1–3). These EOs have a long history of use for medical purposes, in perfumes and cosmetics, and as herbs and spices for foods. EOs are considered to be secondary metabolites in plants; secondary metabolites are organic compounds that are not directly involved in the normal growth, development,...

INTRODUCTION The continuous tendency to reduce the use of antibiotic growth promoters (AGP) in poultry production, due to social concern about generation of antibiotic-resistant bacteria, has resulted in the crucial necessity to find economically viable alternatives that can maintain optimal health and performance parameters under commercial conditions (1, 2). One possible substitute for AGP that has been extensively...

1. Introduction Modern American agriculture has become successful in producing food security despite having less than 1% of the US population actually listing farming as their occupation [1]. The US Census of Agriculture estimates that 8.6 billion broiler chickens, 107 million turkeys, 96 million beef cattle, and 68 million pigs were sold for meat in 2007 with an additional 350 million laying hens and 79 million dairy cows producing eggs and milk [1]. Eighteen to 36 kg of manure...

INTRODUCTION
Antibiotics are considered growth promoters when administered at non-therapeutic (low) concentrations in the feed of food animals to stimulate growth and improve feed efficiency (Costa et al., 2011; Lin et al., 2013). Antibiotics growth promoters (AGP) in the feed of different animal species has been used for more than 60 years in the...

INTRODUCTION The gastrointestinal tract (GIT) microbiota of humans and animals consists of complex populations that include many different species of bacteria along with smaller numbers of fungi, protozoa, and archaea (Zoetendal et al., 2006). Over the last decade our understanding of the diverse functional roles and interactions of the GIT microbiota has rapidly advanced (Zoetendal et al., 2006). For example, in a normally functioning microbiota-host interaction the microbiota...

Background & Aims Butyrate has been shown to potently regulate energy expenditure and lipid metabolism in animals, yet the underlying mechanisms remain to be fully understood. The aim of this study was to investigate the molecular mechanisms of butyrate (in the form of butyrate glycerides, BG)-induced lipid metabolism at the level of gene expression in the jejunum and liver of broilers. Methodology/Principal Findings Two animal experiments were included in...

1. Introduction Aflatoxins are naturally occurring mycotoxins that are produced by some strains of Aspergillus species which are commonly found in cereals worldwide and bring significant threats to the food industry and animal production [1]. At least 14 different types of aflatoxins are produced in nature [2,3]. Aflatoxin B1 (AFB1) is considered the most toxic and is produced by both Aspergillus flavus and...

Throughout the human history, utilization of antimicrobials in food production and human health have been greatly favored. Tremendous improvement in farm animal production and historically unprecedented enhancement in human health protection were marked benefits of utilizing antibiotic in agricultural and human medical arenas. However, the misuse and overdose of antibiotics has resulted in accelerating antimicrobial resistance (AMR). Although the...

It was during 1980's when the concept of functional food first took its commercial shape in Japan. Since then, the business space for functional food has been expanding and will continue to rise over the coming years. Functional foods are referred to as the food additives with health benefits. The growing awareness among the consumers pertaining to the relation between health, nutrition, and diet is basically propelling the demand for these functional food...
