INTRODUCTION: The gastrointestinal tract, often referred to as "the gut," is a complex system consisting of several components, including the epithelium, the immune arm, and the commensal bacteria. This intricate structure plays a crucial role in the overall health and well-being of animals. Understanding the defense mechanisms of the gut is vital for maintaining optimal gastrointestinal function and preventing the invasion of harmful pathogens. (Kogut et al .,...
Increasing prices and low availability of common feed raw materials resulted in the use of alternative ingredients in animal production. These ingredients are often characterised by a high amount of soluble fibre resulting in lower performance and intestinal health issues that limits their inclusion rate in the diet. Bacillus amyloliquefaciens CECT 5940 (Ba) is a probiotic that can produce various metabolites and enzymes relieving the negative effects of soluble fiber and therefore it allows...
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: This study examined the effects of feeding Bacillus subtilis C-3102 (Calsporin® Calpis Co. Ltd., Japan) at the target inclusion rates of 0 CFU/g, 500 000 CFU/g and 1 000 000 CFU/g on intestinal health in weaned pigs after challenge with Porcine Epidemic Diarrhea virus (PEDv). Materials and Methods: A two by three factorial design composed of three diets containing 0 CFU/g or 500 000 CFU/g or 1 000 000 CFU/g of Calsporin® and PEDv...
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 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...
Sudipto Haldar (Research Director at Agrivet) explains changes in the poultry microbiota approach and the effect of certain feed additives, in this Engormix interview....
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;...
Introduction: The effects of the oral supplementation of probiotics on the performance (weight gain and feed intake) and intestinal histo-morphology of the duodenal, jejunal, and ileal mucosa (villus height, width, and perimeter and crypt depth) of two different genetic lines (purebred Large White or crossbred Large White x Landrace) of suckling piglets. Materials and Methods: The suckling piglets were evaluated between 2 and 19 days of age. In total, 276...
The development and maturation of the calf gut is an important process that significantly influences calf’s growth and health during early life. More and more evidence indicate that the colonization and establishment of the gut microbiome can directly and indirectly influence animal’s gut function including development and metabolism, nutrition absorption, barrier and immune function, endocrine and neuron transmitter secretions, which can impact animals’ development and...
Introduction: Using antibiotics as growth promoters in animal feeds has been forbidden since 2011 in South Korea. Probiotic have received considerable attention as suitable alternatives of antibiotics to promote growth in the pig industry. Among several bacterial species used as probiotic, spore forming Bacillus spp. has been considered as the most appropriate probiotic as its spores can to resist harsh environments, thus enabling extensive storage at ambient temperature....
INTRODUCTION Obesity is one of the major health problems throughout the world (Bray et al., 2017). Current obesity treatment strategies, mainly based on food intake control, seem not to be enough to address this multifactorial disorder of pandemic prevalence. In this sense, studies to counteract obesity development based on energy expenditure are recently booming (Marlatt and Ravussin, 2017). In rodents, browning of white adipose tissue (WAT), and especially adaptive...
Nick Gallina (Purdue University) Background: Intestinal barrier dysfunction, inflammation, and elevated expression of heat shock protein 60 (Hsp60) are features of the dysbiotic gut. Probiotics can alleviate inflammation but are ineffective due to poor adhesion and adaptation to the inflamed bowel. We hypothesize that enhancing probiotic adhesion to intestinal cells may augment the immunomodulatory response, mucosal healing, and tight...
Nick Gallina (Purdue University) presents research on probiotic adhesion to intestinal cells that may augment immunomodulatory response, mucosal healing, and tight junction restoration, during the 11th Symposium on Gut Health in Production of Food Animals in St. Louis, USA....
I. Introduction The UK review of antimicrobial resistance presented now outdated 2014 data on AMR consequences for human life (O’Neill, 2016). They estimated that 700,000 people die every year from AMR, with concerning devastating effects on infant mortality. In India, 60,000 newborn babies die each year from antibiotic-resistant neonatal infections. This problem is more prominent in less developed countries but by no means restricted to them. In the US, there are more than two...
