Critical Factors Affecting Feed Enzyme Efficacy to be Highlighted
MEXICO - The 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, during the first full day of the 40th Annual Convention of the National Association of Poultry Science Specialists of Mexico (ANECA).The convention – organised by Asociación Nacional De Especialistas En Ciencias Avícolas De México (ANECA) – will take place between 29 April and 2 May at the El Dorado Royale Hotel, Mexico, with Dr Bedford’s presentation scheduled for 12:45 on 30 April.
Covering the two main classes of feed enzyme – non-starch polysaccharide (NSP)-degrading enzymes and phytases – both individually and when used in combination, Dr Bedford’s talk will highlight the complex interactions that take place between enzymes, their respective target substrates and the gut environment.
Dr Bedford stated: “The US$1-billion feed enzyme market is dominated by NSP-degrading enzymes and phytases. 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.
Dr Bedford added: “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. 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,” he concluded.
