Poultry 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.

Research findings highlighting the efficacy of Xylanase, a NSPase marketed under the product name Xylamax by BioResource International (BRI), were shared at the Poultry Science Association (PSA) annual meeting held July 11-14 in San Antonio. The poster presentation detailed the improvement to body weight and gut health parameters that was achieved by supplementing with Xylamax during a study with 1,350 day-old mixed-sex Cobb 500 chicks grown to 42 days of age. The three feed treatments...

Many challenges are facing the broiler industry. Antibiotics have been used in animal feed to mitigate the negative effect from various sources; however, increased legislation restrictions and consumer demands are increasing pressure to limit antibiotics usage in the poultry production. The industry is continuing to investigate different approaches to protect chicken health while maintaining the feed cost load and improving desired growth efficiency. One way to do that is through...

Probiotics. Enzymes. Fiber. Gut Health. While these are all buzz words in human health, they are also topics that are increasingly being studied in the animal industry to aid performance and health of livestock raised to produce protein for human consumption. Moreover, as the poultry industry moves away from subtherapeutic antibiotic growth promoters (AGP) usage, multiple technologies have been explored to protect the health of birds from pathogens, while still maintaining low feed cost and...

A few years back, it was discovered that in-feed coniferous resin acids support gut integrity and luminal homeostasis in the intestinal mucosa of broiler chickens by reducing inflammation-associated degradation of collagen. This very positive, direct effect on intestinal tissue manifests as improved bird performance and reduced abundance of inflammatory T-cells in gut mucosa. Such a mechanism-of-action has not been discovered for any other feed ingredient or natural feed...

A study was conducted to investigate whether the functional oligosaccharides released in situ as a consequence of fibre-degrading enzyme application ameliorate the severity of necrotic enteritis (NE) in broilers offered wheat- or maize-based diets. Day-old Cobb 500 mixed-sex broilers (n = 1536) were assigned to a 2 × 2 × 4 factorial arrangement of treatments, with six replicates per treatment, for 21 days. Factors were cereal type (wheat or maize), NE challenge (without or with),...

I. INTRODUCTION Xylans, together with β-glucans and cellulose constitute non-starch polysaccharides (NSP) that cannot be fully degraded by monogastric animals (Cowieson at al., 2008). NSPs have an antinutritive effect by increasing the viscosity of the intestinal digesta (Choct and Annison, 1992; Craig et al., 2020). This increase in digesta viscosity causes an impairment of nutrient bioavailability and a decrease in metabolizable energy, lowering the overall performance of...

I. INTRODUCTION The chicken meat industry has made tremendous production gains through advanced utilisation of genetic selection and nutritional understanding to ensure that chicken meat remains a low cost, desirable product that consumers continuously demand (Zuidhof et al., 2015). The industry now requires new approaches to further advance efficiency and production, with developmental programming at the forefront of industry development (Hynd et al., 2016). Developmental...

About 50-70% of all antibacterial agents used in broiler production are applied to reduce bacterial intestinal infections (bacterial enteritis). Properly conducted prophylaxis and appropriate follow-up can be effective methods of reducing the amount of antibiotics that are used in poultry production. Impaired feed digestion and nutrient absorption lead to the development of indigestion and diarrhoea in poultry. These diseases, apart from subclinical coccidiosis, have the...

Introduction. The indigestible soy galactooligosaccharides (GOS) stachyose and raffinose are considered anti-nutritional factors in poultry because they decrease the metabolizable energy of soy protein (Leske et al., 1993) and decrease performance (Jiang et al., 2006). The objective was to investigate if there was a dose-response effect of increasing levels of the soy GOS raffinose and stachyose in feed on performance and gastrointestinal health including AMEn, nitrogen retention and...
