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.
The EU Commission has granted Danisco Animal Nutrition authorisation for the use of Phyzyme XP 10000 TPT and Phyzyme XP 10000 L in broiler, layer, turkey, duck, sow, piglet and grower/finisher feeds.
Phyzyme XP 10000 is a highly concentrated phytase feed enzyme, containing 10000 FTU phytase/g.
Phyzyme XP is a new generation E. coli phytase feed enzyme. Trials have shown that this E. coli phytase offers more value compared to 'traditional' fungal phytases.

DL-methionine has a history of more than 50 years of safe application. In the MetAMINO process for example all intermediates are completely converted and the final product is purified in a multi-step process ensuring reliable product quality which also means that MetAMINO is free of undesired substances. Future L-methionine processes have still to prove their capability to deal with the chemicals involved and to generate a safe product of reliable quality comparable to DL-methionine.

Economic losses associated with the incidence of egg shell defects are important when evaluating the profitability of a layer operation (Bell, 1998; Gomez- Basauri, 1997; Roland, 1988; Hamilton et al., 1979). Worldwide estimates of reduced shell quality leading to egg breakage have been found to range from 6 to 8% (Anderson and Carter, 1976; Folkerts, 1976; Roland, 1977; Hamilton et al., 1979). In the USA alone this has been estimated to be around 8% (Roland, 1988). Shell defects are not...

At the last EU Standing Committee meeting of 22nd October 2007, the European Commission has granted DSM Nutritional Products an extension to the approval given to its phytase feed enzyme, RONOZYME® P, for ducks. RONOZYME® P (Granulate and liquid) is now approved for salmonids, broiler, layer, turkey, duck, sow, piglet and fattening pigs. The large spectrum of EU authorizations is of major added-value for multi-species feed factories. The European Food Safety Authority (EFSA), in charge of...

Please give details about please give detail about paptizymes/bitazymes.
Should use separately in poultry feed or all combination enzymes should be used in broiler?
What is paptizymes and bitazymes, is it used full in broiler feed?

Introduction: evolution of practical phytase use The beneficial effects of phytase on the availability of phytate phosphorus have been known since the 1960s (Nelson, 1967) with considerable research having been undertaken and reported in the intervening years. Phytases have been available for many years; but not until the environmental impact of agriculture and urban sprawl became a political issue was there pressure to develop and utilize phytase in livestock feeds. The...

Introduction Mycotoxins are metabolites produced by fungi which are toxic to livestock when consumed in biologically significant amounts. The resulting diseases are referred to as mycotoxicoses. Mold growth and mycotoxin production on feed grains are influenced by many factors but the most important of these is moisture. Stored grains should contain less than 15% moisture to minimize mold growth. Fusarium fungi are commonly found in temperate climates; and Fusarium mycotoxins are...
