The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.
INTRODUCTION Under current production systems, turkeys have traditionally been protected from pathogenic microorganisms by vaccination and antibiotics. For decades, subtherapeutic doses of antibiotics have commonly been used within the poultry industry to improve production performance and reduce pathogenic microbial challenges. However, negative consumer perception and increased regulatory guidance prohibiting the use of growth promoters or antibiotics within the animal...
Caring for birds’ health is an essential factor in achieving good production levels. When diseases such as coccidiosis afflict birds, they cause physical losses for the flock and economic losses for producers. Recent estimates show that annual losses...
Guillermo Tellez (University of Arkansas) presented published results conducted on a Bacillus direct-fed microbial to increase performance, during the 8th Symposium on Gut Health in Production of Food Animals in St. Louis, USA....
Yeast products certainly have a role in supporting the performance and gut health of animals but choosing the right one can be tricky as there are plenty of products with similar claims. The yeast product manufacturers naturally emphasize those characteristics in...
1. Introduction Redox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention [1–6]. There are a range of redox pairs in cells/tissues responsible for redox homeostasis maintenance/regulation. They include, but are not limited to, NAD+/NADH, NADP+/NADPH, GSSH/GSH (glutathione system), Trxox/Trxred (thioredoxin system), protein thiolsox/protein thiolsred. It is...
Introduction Wheat and barley as alternative cereals can be successfully replaced with corn in poultry diets. These grains could locally grow in many areas of the world and have lower water requirements than corn (Ravindran et al. 1999; Lin et al . 2010). The major components of wheat and barley are starch and proteins, though they have considerable content of non-starch polysaccharides (NSP), derived from the cell walls (Olukosi et al . 2007;...
Last April 29, 2021, Biovet S.A. organized a videoconference with the theme: “ Improving profitability, performance and welfare with natural additives “ During the talk, were detailed some of the most common mistakes...
Introduction Poultry producers attempt to control infectious diseases through a variety of means, including appropriate farm management practices and breeding genetically resistant lines (Sartika et al. 2011; Scott et al. 2018). Unfortunately, existing farming conditions favour increased chicken densities in poultry houses, increasing the risk of spreading entero-pathogens such as Salmonella and Clostridium spp. (FAO 2013). For over half a century, veterinarians and poultry...
INTRODUCTION Coccidiosis is a major enteric disease of chickens that is caused by several distinct species of Eimeria protozoan parasites infecting different areas of the gut. Coccidiosis primarily damages epithelial integrity in the intestine decreasing nutrient utilization and resulting in an annual loss of over $3.2 billion in the poultry industry globally (1–3). With the onset of coccidiosis, Eimeria elicits a local inflammatory response in the intestine, increasing...
Robust immunity in poultry flocks is essential to reducing reliance on antibiotics. Phileo’s post-antibiotic program provides three innovative nutritional solutions to boost overall poultry health. Safglucan ® , a key element...
INTRODUCTION Variability in the nutritional value of feed ingredients for poultry (and indeed other livestock species) has been widely reported over several decades and has been the impetus behind a sustained body of research work. For example, Sibbald and Slinger (1962), Mollah et al. (1983), and Leeson et al. (1993) reported variation in the apparent metabolizable energy (AME) content of corn (3,476–3,960 kcal/kg dry matter [DM]), wheat (2,948–3,960 kcal/kg DM),...
The 2021 Symposium on Gut Health in Production of Food Animals is pleased to announce that this year’s invited speakers are Mick Bailey, Melha Mellata, and Phillip Myer. Complete details on these...
1. Introduction Whey is the valuable by-product of the cheesemaking process resulting after the production of cheese, whey cheese or casein from milk. It represents 90% of the volume and 50% of the solids of milk and it is characterized by its high concentrations of water, lactose and sodium [1,2]. Whey disposal is problematic, due to its high organic matter content and resultant high biological oxygen demand. Large scale commercial cheese plants usually process whey to...
There is increasing pressure for the use of antibiotic growth promoters (AGPs) in poultry diets to be discontinued or reduced. In this context, the search for natural additives such as organic acids (OA) and essential oils (EO) has increased. Previous studies have reported beneficial effects on gut health of supplementing poultry diets with these natural feed additives. As in many countries the use of AGP is still allowed and the adoption of programs combining the effects of AGPs with feed...
INTRODUCTION Studies from humans and rats have showed the intestinal epithelium represents the largest area of exposure of the body to external pathogens and toxins (Abreu, 2010; Slack et al., 2012). The secretory immune system, including secretory IgA (sIgA) and the mucus, serves as the first line of defense to limit epithelial contact with pathogenic microorganisms and other potentially dangerous antigens (Abreu, 2010; Slack et al., 2012; Zhang et al., 2015). Immunoglobulin A...
Introduction Advances in genetics has certainly produced commercial strains of poultry and pig with greater performance (e.g. growth, reproduction) with minimal feed input. For example, over the last 5 decades, the body weight of broilers at 42 days has increased by 25-50 g per year and the feed conversion ratio to 2 kg body weight has improved 2-3 points annually (Havenstein et al., 2003; Gous, 2010; Aviagen, 2019). With the introduction of crosses in...
