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.
WHY IN VITRO METHODS MATTER Traditionally, diet formulation has relied on in vivo trials to determine digestible and metabolizable energy. These trials are accurate but slow, costly, and raise ethical concerns. Existing in vitro systems, meanwhile, are often too simplistic or poorly standardized to replace live-animal trials. Simulated Digestion System (SDS III) changes this. Developed over more than a decade of research, it uses computer-controlled digestion to simulate the...

Introduction to Immunity Immunity refers to the body's ability to resist or defend against infections, diseases, and other unwanted biological invasions. There are two main types of immunity. Innate immunity is the host's first line of defense against invading pathogens but some pathogens particularly immunosuppressive viruses have evolved sophisticated mechanisms to evade the host's innate immune responses and survive within the host. Adaptive Immunity targets...

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.
