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.
Introduction Protein is a major and expensive component of animal feed, accounting for about 20% of the total dry matter content of swine and poultry diets. Soybean meal is the leading source of feed protein [ 1 ]. In the gut, protein is hydrolyzed by endogenous proteases, principally pepsin (EC 3.4.23.1), trypsin (EC 3.4.21.4) and...

ABSTRACT
Improving productivity, reducing feed cost or increasing economic efficiency are main challenges in laying hen farms. Thus, the present experiment was conducted to study the effect of different levels of lysine and Total Sulfur Amino Acids (TSAA) on productive performance, egg quality and economical evaluation of Lohmann Brown laying hens . A total number of 144 hens...

The 50-year historical review of soybean meal (SBM ) published in Feedstuffs in 1970 by Dr. J.W. Hayward highlighted many of the pertinent advancements concerned with animal nutrition, product development and promotional aspects of U.S. SBM. In fact, 1920 marked not only the beginning of the industrial production of soybean oil and SBM in the U.S., but also the year that the American Soybean Assn. was founded (Hymowitz, 1990). The use of SBM at the time this 50-year review was published was...

The animal feed enzymes market is expected to garner noteworthy gains on account of surging concerns over disease outbreak among poultry animals. Imposition of strict regulations to encourage livestock safety is supporting animal feed enzyme adoption.
Livestock owners nowadays are willing to buy high-quality feed grades. The product mostly helps provide a nutrition-rich balanced diet to livestock. In addition, these high-quality feeds ensure animal wellbeing and help curb potential...

Introduction Globally, feeding cost and the price of poultry product have recently increased due to increasing competition between human and animals for the same feed resources. Agriculture by-products are valuable feedstuffs that can be used in animal nutrition (Al-Harthi et al. 2018a, 2018b). In animal nutrition feed processing and feed additives as well have been used for improving the feeding values of feeds particularly of agricultural byproducts (Dozier et al. 2010;...

Chicken meat production is more sustainable and has lower environmental impact than porcine and bovine meat production. Chicken production uses less feed consumed for each kilogram of meat produced and uses less land and water for both farming and feed production (Flachowsky et al., 2017). Moreover, the broiler production industry has, for many years, continuously improved animal performance, reflected by ever decreasing feed conversion (kg feed consumed per kg body weight) and reduced time...

INTRODUCTION The main idea of using phytase in the diet for broilers is based on the reduction in the content of available phosphorus ( av P) accompanied by the inclusion of this enzyme. With this, it is expected that the av P content present in the diet, added to the content of phytate P ( phy P) made available by the catalytic action of the phytase, meets the P requirement of the bird (HAN et al., 2009). The industry related to broiler nutrition,...

Introduction Current broiler growth rate is partly the result of an intense genetic selection; 1 therefore, feeding is important to achieve the maximum productive expression. Success attained until now in this practice has been due to better knowledge of the functions that different nutriments carry out, which in turn allows higher precision when establishing nutrimental needs. 2 To be able to feed...

Introduction Coccidiosis is considered one of the most important poultry diseases worldwide due to the economic losses it produces in performance and due to medication usage (Williams, 2002; Dalloul and Lillehoj, 2005). The use of vaccines to prevent coccidiosis has proven to be successful (Lee et al., 2009; Danforth, 1998; Williams and Gobbi, 2002) and is widely used today in the U.S poultry industry (Agri-Stats, Fort Wayne IN). However, in the process of developing immunity,...

Betaine supplementation has numerous positive effects on animal performance. Recent studies with betaine from sugar beet molasses looked if this naturally derived betaine can substitute a certain amount of added methionine in broiler diets. Betaine (BET) or trimethylglycine is a zwitterionic (neutral molecule with bipolar structure) quaternary ammonium compound. It was first discovered in the juice of sugar beets (Beta vulgaris) and afterwards found in other plants (spinach)...

Introduction Calcium reduction and phytase supplementation were considered an important combination in broiler nutrition. Wooden breast (WB) has been considered one of the most important challenges in the Poultry Industry in the 21st century. The superdosing of phytase can affect metabolic functions in the early life of broilers, and the studies with the interaction of this enzyme with calcium, phosphorus and carcass evaluation must be incremented. Based on this, calcium...
