Enzymes in poultry nutrition
Enzymes are proteins involved in all anabolic and catabolic pathways of digestion and metabolism. Digestive enzymes are categorised as endogenous or exogenous. Endogenous enzymes are produced by the animal and exogenous enzymes are administered from outside. Enzyme supplementation decreases nutrient loss through excreta, reduces diets nutritional levels, improves nutrient availability; thus, enhances production efficiency and profitability. In addition, exogenous enzymes hydrolyse non-starch polysaccharides, increase the usage of feed energy, reduce negative impacts of non-digestive residues on digesta viscosity, and improve gut microbial ecosystem. Cellulase, glucanase, pectinase, xylanase, galactisidases, phytase, non-starch polysaccharides degrading enzymes, amylase, lipase, cellulase, and protease are the most common enzymes used in poultry feed.
1. Introduction Although the global production of duck meat reached 6.07 million tonnes in 2022 [1], an increase of 111.5% since 2000, there is limited information available on different areas of commercial duck production compared to broiler chickens, laying hens, or even turkey. Along with the increase in meat production due to more ducks being raised annually, there has been a significant improvement in genetic selection to increase the growth rate. Particularly, Pekin ducks have...

Introduction Barley is one of the main cereals produced in Norway and is used in broiler feed in low amounts due to high content of non-starch polysaccharides (NSP) (Bedford 1995; Knudsen 2014; Svihus and Gullord 2002) and lower energy value compared to maize, wheat or sorghum (Choct and Annison 1990; Khalil et al. 2020). The NSP fractions comprising soluble βglucans and arabinoxylans have gel-forming characteristics and are known to increase intestinal viscosity (Choct 2006),...

The use of feed enzymes in monogastric nutrition has been a cornerstone of feed efficiency and environmental management for decades. However, a recent analysis suggests that the industry's long-held "scientific dogma" may be limiting the full potential of these additives. In an article on AB Vista's website titled "Enzymes through the ages: rethinking their use in animal nutrition," Mike Bedford (AB Vista) argues that the industry's focus on simple, measurable outcomes has created a...

The use of barley in broiler diets is limited because of the presence of β-glucans, which negatively influence nutrient utilisation and bird performance. These negative effects may be partly overcome by exogenous carbohydrases containing β-glucanases. In the current study, the influence of a multi-component carbohydrase (Ronozyme multigrain, DSM Nutritional Products, Singapore) on nitrogen-corrected apparent metabolisable energy (AMEn; assay 1), and, apparent ileal digestibility...

Gastrointestinal (GI) passage rate of feed influences nutrient digestibility and absorption, as it dictates the amount of time the digesta are exposed to digestive enzymes, the intestinal villi and microbial fermentation (Vergara et al. 1989; Svihus 2010). The titanium dioxide (TO 2 ) marker technique is currently widely practiced for evaluation of GI passage rate. However, this method requires euthanising the bird to obtain digesta samples, which has negative implications from an...

I. INTRODUCTION Protease enzymes can improve the dietary protein utilization. Therefore, it is possible to decrease the level of dietary protein to save on feed cost while maintaining performance, reduce nitrogen excretion in the environment, and minimize the risk of enteric infections. The objective of this study was to evaluate the effect of a protease on performance and intestinal health of broiler chickens fed a standard diet or a low-density diet. II. MATERIALS AND...

I. INTRODUCTION Microbial enzymes are now routinely used in broiler chicken diets to reduce the effects of antinutritive factors (ANF) in feed and/or improve the digestion of nutrients (Bedford, 2011). There is a suite of enzymes that target ANF such as non-starch polysaccharides (NSP) and phytic acid as well as products which improve the digestion of nutrients such as protein and minerals. The major cereals used in poultry diets are wheat, maize, sorghum and barley. The objective of...

With approximately 30.2-56% crude protein (CP), cottonseed meal (CSM) is regarded as one of the closest alternative protein sources to soybean meal (SBM). It is used at relatively low levels to replace soybean meal in diets for broiler chickens (Swiatkiewicz et al., 2016). While its value at such low levels has been well established, the potential for using CSM at higher levels when fed as such or supplemented with microbial enzymes is not well understood. Similarly, there have been...
