Explore all the information onPoultry gut health
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.
The gastrointestinal tract is one of the main organs affected by heat stress. Diarrhea, watery feces, digestive infections, inflammation of the intestinal tissues, etc are triggered by the exposure to high temperatures. In recent years, the gastrointestinal problems that happen during heat stress have been linked to a failure of the gut barrier function (leaky gut)....
A trial conducted in July 2020 in a commercial farm showed that the administration of DigestoCid© to caged broilers significantly improved their performance. Moreover, the use of the product increased the proportion of beneficial bacteria in the intestine. Outline of the...
A success case in a breeding farm proved that the use of PlusProtect Digestive© and PhytoMax© can significantly improve productive parameters such as laying rate, FCR, egg quality, egg mass and percentage of qualified eggs. OUTLINE OF THE CASE Animals:...
INTRODUCTION Antibiotics used as growth promoters (AGP) have successfully controlled dysbiosis and enteropathogens for the past 50 years (1). However, the recent increase in worldwide non-AGP poultry production is challenging the industry in management, health, and animal welfare due to the increase of enteric and systemic diseases (2, 3). One of the most accepted theories of AGP mechanism is its role in reducing low-level inflammation (4) and immunologic stress (5) that can be...
INTRODUCTION Spray-dried plasma (SDP) is a highly digestible protein ingredient rich in functional molecules, manufactured from animal blood collected from federally inspected slaughter facilities, and spray-dried to preserve the functionality of its components (Coffey and Cromwell, 2001). It is a diverse mixture of functional molecules consisting of immunoglobulins, albumin, fibrinogen, lipids, growth factors, enzymes, hormones, and other components...
I. INTRODUCTION The withdrawal of antibiotics has caused an increased prevalence of necrotic enteritis (NE) in broiler chickens, making it the most common disease in the poultry-industry globally. Direct fed microbials (DFMs) have been shown to have great potential as alternatives to antibiotic growth promoters (AGPs). Bacillus amyloliquefaciens produces several extracellular enzymes including cellulase, hemicellulose, amylase, xylanase and proteases. Its application has been...
Yeast cell wall (YCW) fractions have proven effective in reducing the incidence of necrotic enteritis induced by Clostridium perfringens. Dietary supplementation with YCWs stimulates the systemic innate immune responses of broiler chickens, suggesting the role of these products in regulating immune homeostasis (Alizadeh et al., 2016). In a proposed mode of action of YCW on bacteria, the branched lateral chains of the mannan-oligosaccharides (MOS) in the YCW structure bind the bacteria and...
INTRODUCTION As a fungal secondary metabolite of the Aspergillus species, aflatoxin B 1 (AFB 1 ) is known to be the most toxigenic mycotoxin (Yunus et al., 2011). Feed contamination with AFB 1 has been a major feed safety concern due to its negative effects on growth performance, production, hepatic functions, and immune system in many livestock species (Ledoux et al., 1999; Yarru et al., 2009; Andretta et al., 2011; Grenier and Applegate,...
INTRODUCTION
Coccidiosis is an enteric disease caused by protozoa of the genus Eimeria that affects several animal species, including poultry. Eimeria multiplication in the intestinal epithelium leads to enterocyte destruction and severe tissue damage, which negatively affects poultry health and welfare status (1). Although difficult to predict, researchers have estimated that the loss in productivity induced by clinical and...
Calcium is an important cation in chicken diets, being the most abundant element in the body of the chicken. Its functions include: mineralization of bones, blood clotting, enzyme activation, neuromuscular function, muscle contraction, and intracellular signaling. However, high dietary Ca is a limiting factor for phytase efficacy and the formation of insoluble Ca-phytate complexes decreases Ca and P availability. Furthermore, Williams (2005) has shown high dietary Ca concentration in the...
Dr. Megan Edwards, Animal Nutrition Consultant at Integral Nutrition, goes deeper on the importance of Betaine as a multi-functional nutrient with numerous positive effects on animal performance....
Phasing out of in-feed antibiotics in the poultry industry has caused necrotic enteritis (NE) to become a primary concern in commercial poultry production in many countries. Damage to the intestinal mucosa caused by this disease leads to impaired broiler productivity. To gain a better understanding of the impact of NE on transcriptome changes, a whole transcriptome sequencing (RNA-seq) was performed on jejunal RNA of challenged broilers to identify the pathways affected by this...
I. INTRODUCTION Antibiotics as growth promoters (AGPs) have been extensively used at sub-therapeutic levels in poultry production to prevent diseases and promote growth performance. However, the persistent use of antibiotics can increase antibiotic-resistant bacteria and antibiotic residue accumulation in the animal products as well as potentially transferring resistant strains to humans through the food chain (Jazi et al., 2018a). Consequently, the poultry industry has been...
I. INTRODUCTION
One of the most sustainable types of production of animal protein is chicken meat production. Chicken production needs less feed consumption per kilogram of produced meat and uses less land and water for both farming and feed production. The major reason for this is the continuous improvement of animal performance, reflected in an ever decreasing feed conversion (kg feed consumed per kg body weight) and reduced time to achieve market...
Intensive farming is drastically increasing yearly in South East Asia to comply with the growing demand of animal protein of the region. Intensive farming has been possible worldwide thanks to the genetic improvements and technologic and productive investments done, which have allowed to reduce the breeding period while increasing the benefits. Animals are under a high pressure in this production system to achieve the desired productive parameters, which makes them more sensible to the...
