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.
This study investigated the effects of Bacillus -based probiotics on performance and intestinal health in broiler challenged with Clostridium perfringens -induced necrotic enteritis. One-day-old Arbor Acre (n=480) were randomly assigned to four treatments with 10 cages of 12 birds. Dietary treatments were; basal diet negative control (NC), with no probiotics nor antibiotics formulated to contain 2,930 and 3,060 kcal/kg with 24.1 and 16.0% CP, for starter and finisher diet,...

Introduction Protein besides biologically active compound in the body exists as enzymes & hormones, also plays important role in physiology of living organisms. Soybean meal (SBM) is complete conventional protein source with well-balanced amino acids profile. On the other hand due to increase in prices of SBM, alternative sources like groundnut cake, sunflower meal, guar meal, rapeseed cake, cotton seed cake, copra meal, maize gluten, DDGS etc. are used, but they have...

Introduction: Poultry meat industry has been more dynamic than egg industry over these years. Broiler breeder companies are making every effort to produce progeny that produces higher (breast) meat yield, lower FCR and better weight gain. Consequent to faster growth rate, a part of the energy utilized in the past to maintain health and disease resistance is now diverted for higher growth & production resulting in increased risk for...

Components of Gut Health The intestine is a complex organ that comprises regions with distinct structural and physiological functions specialized in digestion and nutrient absorption. Simultaneously, the gut represents the primary contact site with foreign antigens and pathogens that can enter, reside and disseminate to the internal organs. For this reason, the gut harbors the majority of immune cells, referred to as gut-associated lymphoid tissues, when compared to other tissues....

The overuse of antibiotics has led to the development of antibiotic-resistant bacteria in poultry production. However, there are some additives, like probiotics and prebiotics, which can be used as alternatives to reduce the need for antibiotics. In that sense, how can we determine if feed additives are helpful for birds? Simply put, maintaining a healthy gut is crucial for the overall well-being of poultry, since it leads to better growth and immunity. That means that developing models to...

The objective of the present studies was to evaluate: (1) the in vivo impact of supplementation with a Precision Biotic (PB) on the growth performance and microbiome modulation of broiler chickens; (2) the modulation of functional pathways of the microbiome collected from animals with low and high body weight gain, and (3) to develop a Microbiome Protein Metabolism Index (MPMI) derived from gut metagenomic data to link microbial protein metabolism with performance. The in vivo work consisted...

Coccidiosis is an important health problem in broilers, caused by infection with a highly contagious intestinal parasite of the genus Eimeria. Anti-coccidial drugs are widely used for the prevention of coccidiosis in broilers. However, multi-resistance coccidia is a potential threat to poultry production. Solid-state fermented products produced from B. licheniformis not only contain B. licheniformis spores but also have B. licheniformis derived...
