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.
In the animal food industry, enzymes can help improve animal performance and production economics through a variety of mechanisms: breakdown of substrates in feed and reduction of anti-nutritional substances, such as hydrolysis of phytic acid to improve phosphorus availability.

Poultry meat is a particularly important protein source as broilers have a high feed efficiency and short production cycle compared to other animal products, making it an affordable, nutritious source of animal protein (Marangoni et al., 2015). Therefore, strategies to improve production performance of broilers will require significant research as this is key to future food security. One nutritional strategy to improve sustainability of poultry production systems is improving the efficiency...

The on-going battle against African Swine Fever and Covid-19 have caused major challenges globally affecting both food production and food security. This has been very evident in swine production, as most top pork producers and exporters were affected. Spain, being the top pork exporter, was among the first countries to be hit by the Covid-19 pandemic causing disruptions in pork supply not only to its exports but also affecting domestic supply in EU as well. This has also significantly...

We are presently going through a challenging period of high prices of raw materials and a limited availability of some of these materials. The use of less common raw materials that are readily available, and potentially less expensive, can be an alternative to traditional protein and energy sources and may help reduce the pressure on feed costs. However, new types of ingredients need extra attention to be paid to make sure they are suitable for feed processing, are free of contaminants,...

Introduction Protein is a major component of animal tissues and products. Thus, adequate intake of dietary protein is essential to optimise growth, production performance, and feed efficiency in poultry. Soybean meal is most commonly used protein source and used around 20-30 % in poultry feed. Now days protein feed ingredients like soybean meal are consistently increasing in cost; so protein has become one of the most expensive nutrients in poultry diet. After feed consumed by...

INTRODUCTION In the United States and most parts the world, the biggest portion of poultry diets is comprised of carbohydrates, with corn being the main cereal grain used in the feed industry (Moran, 1982; Ai and Jane, 2016; Agristats, 2018; IGC, 2018). Corn is dried on the field or usually dried either by constant flow or batch drying after harvesting, so it could be included in poultry feeds. It has been reported that temperatures while drying could reach more than 100C mainly...

No common feedstuff is 100% digested. In practice, 10-15% are excreted in faeces without bringing any means to bird requirement and in addition cause potential anti-nutritional effects. Thus, there is no doubt poultry benefits the most from use of exogenous enzymes and is becoming a...

SUMMARY To determine the ideal digestible tryptophan-to-digestible lysine ratio in diets for laying hens of 42 to 58 weeks of age, 240 Hy-Line W-36 hens at 42 weeks of age were distributed in a completely randomized design with five treatments, eight replicates and six birds per experimental unit. At 42 weeks of age, the birds were subjected to experimental treatments that consisted of diets with equal amounts of nutrients, except for the digestible tryptophan level. The...

In a report journal from Nature Sustainability, it was mentioned that soybean meal is the largest global source of protein in livestock feed and its global production has doubled since 2000. More than half of the world’s soybean production are coming from Brazil and Argentina alone. While livestock population continues to grow by 3-4%, the pressure to produce more protein and energy source in their diet will continue to increase as well. However, several headwinds have caused prices of...

Phytase supplementation of broiler diets can improve energy, amino acid, calcium (Ca) and phosphorus (P) utilization. Both fungal- and bacterial-derived phytases are commonly added to broiler diets. Phytases from different sources and even from the same source can have different pH optima, heat stability, and catalytic properties (Dersjant-Li et al, 2015). Furthermore, when different microbial phytases are included in diets, their efficacy in vivo can vary in comparison to their assayed...

Introduction The use of enzymes in modern non-ruminant production has become universal. This is due to the extensive benefits observed on the productivity of both poultry and swine with its use. Although most feed ingredients used in monogastric nutrition contain adequate nutrients, monogastric animals are not able to efficiently utilize all the nutrients present in these ingredients. This has been attributed to several factors including the presence of antinutritional factors...

1. Introduction The conversion of dietary protein and amino acids into the protein of chicken-meat is indeed a dynamic process. Quite typically, broiler chickens attain a live weight of 2.918 kg at 42 days post-hatch and a carcass weight of 2.151 kg following processing. This translates to 376 g of carcass protein as a Ross 308 broiler carcass contains 175 g/kg protein [1]. Broiler chickens consume 4.702 kg of feed over 42 days with dietary protein contents declining from 230 to...
