Critical factors influencing feed enzyme efficacy in poultry diets will be the subject of a presentation by Dr. Mike Bedford, AB Vista's research director, at the 40th Annual Convention of the National Association of Poultry Science Specialists of Mexico (ANECA).
The Convention will take place between April 29 and May 2 at the El Dorado Royale Hotel, Mexico, with Dr. Bedford's presentation scheduled for 12:45 on April 30.
Covering the two main classes of feed enzymes, non-starch polysaccharide (NSP) degrading enzymes and phytases, both when used individually and in combination, Dr. Bedford's talk will highlight the complex interactions that take place between enzymes, their respective target substrates and the gut environment.
"The US$1 billion feed enzyme market is dominated by NSP-degrading enzymes and phytases," Dr. Bedford says.
"The main reason for their use is economic benefit, yet the efficacy with which this is achieved depends on a wide range of complex interactions that take place within the bird.
Such interactions are even more complex when using two different classes of enzyme in combination. A detailed understanding of how each affects performance is therefore critical if return on investment made in feed enzymes is to be maximised."
The latest research has also highlighted the importance of how enzymes within each class can indirectly change gut microflora.
"Such changes may well hold the key to both an improved level of response within the bird and greater consistency across different flocks, diets and seasons," Dr. Bedford adds.
"However, more research is needed in order to fully understand the mechanisms involved.
For now, the key is to focus on products and combinations that have been proven in independent research, and which have the data to back up performance claims."
