DSM, an animal health company, will host a symposium on substrates for exogenous enzymes during the 2013 meeting of the Poultry Science Association to be held in San Diego, Calif., from July 22-25. Entitled "Possible Substrates for Exogenous Enymes," the event will be one of a number of meetings and workshops to be staged at the Poultry Science Association 2013 on July 22 at 1 p.m.
The use of exogenous enzymes has increased considerably in the past 20 years to support animal performance and feed cost savings while delivering improved animal health and enhanced sustainability. However, questions still remain concerning how much enzymes can potentially release from different substrates and also the results of this effect.
Before being able to characterize the effect of enzymes, it is essential to understand the full range of possible substrates available in livestock feed. It is also critical to understand how the substrates themselves can be changed according to the quality and composition of the feed and the requirements of the specific livestock group. Such changes do not affect the quantity of substrate available in the feed, but they do affect the digestibility of certain nutrients. This increases the space in which enzymes can act, which in turn heightens the effectiveness of their action. This aspect of the use of enzymes in animal feed has received inadequate attention in the past. The DSM symposium aims to readdress this balance.
Chaired by Dr. José Otávio B. Sorbara of DSM and moderated by Dr. Roselina Angel, assistant professor at the Department of Animal and Avian Sciences at the University of Maryland, the symposium includes contributions on "Fiber and NSP Content and Variation", "Phytate Concentration and Variation in Different Crops", "Starch: Is it a possible substrate?", "Protein and Amino Acids: What is Undigestible?" and "Formulating Poultry Diets Based on their Undigestible Fractions."
Dr. Steve Koenig, executive director of the Poultry Science Association, says, "The Poultry Science Association is excited about collaborating with DSM to present the very best scientific information in a symposium that will draw much needed attention to the impact of feedstuff variability on the efficiency and predictability of exogenous enzymes."
Dr. Mark Stock, president of DSM Animal Nutrition and Health, comments, "DSM is excited to be hosting this important symposium, at which a distinguished line-up of leading experts in the field of feedstuff evaluation will be presenting the results of their most recent research. Their contributions, and the associated discussions, will provide up-to-the-minute insights into the value-adding application of enzymes in today's highly competitive global poultry industry."
