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.
Global feed Enzymes Market on a Growth Trajectory Valued at USD 1.49 billion in 2025, the market is projected to reach USD 2.38 billion by 2034. Asia Pacific has emerged as the most influential region, accounting for 34.51% of the global market share in 2025. This dominance underscores the region's...

1. Introduction Poultry is the most consumed animal protein source in the world, and the trend is expected to continue increasing [1]. The world population reached 8 billion in 2022, and is likely to reach 9 billion in 2037 [2], which will continue to increase pressure on the global chicken-meat industry. One way to meet this increasing demand is to improve the efficiency of chicken-meat production. Precision nutrition is a strategy to improve growth efficiency, reducing the...

INTRODUCTION There is an increasing demand for animal-based protein to meet the nutritional needs of the ever-increasing global population. The protein obtained from broiler meat is one of the most promising animal-sourced proteins, considering its quality and affordability. To contribute to the supply of animal-based protein, fastgrowing broiler strains have been developed for higher muscle yield in a short period. However, broiler’s faster growth in a limited time results in...

INTRODUCTION Reducing the production cost of quality meat and eggs for the ever-growing world population is a prime target of the poultry industry. Conventional feed ingredients like corn and soybean meal are widely used in broiler feeding programs, which increase the competition among food and feed and lead to raise production costs (Donohue and Cunningham, 2009; Stefanello et al., 2016). Several strategies were attempted to minimize the cost per unit production, such as...

DESCRIPTION OF PROBLEM There are growing concerns that the continual feeding of inorganic P is leading to the development of eutrophication of surface waters. Excessive P runoff from soil causes an accumulation of P in water sources, and this can result in toxic algal blooms and fish kills [1]. The availability of P from feedstuffs of plant origin is low for poultry because a greater proportion of the total P is present in the phytate form, a form that has low availability...

Introduction Heat stress is one of the major problems of poultry in heat areas of the world including Iran, especially in summer, leading to reduced performance, the production, feed intake, growth rates and effective use of the feed (Sahin ., 2009). In general, birds have a thermal comfort zone, which ranges between 18 to 22 ° C and no problem for the physiological regulation of body temperature in this range will. Birds lack sweat glands, increase in...

INTRODUCTION Cereal grains and vegetable protein sources contain between 10-75% of non-starch polysaccharides (NSP). NSP in cereals form part of the cell wall structure and in vegetable proteins, such as legumes, may also play a role as an energy storage material. As far as monogastric animal nutrition is concerned, NSP as the major part of fibre (fibre is the sum of NSP and lignin) are regarded as feed components that...

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...
