Feed management is a means of source control for environmental pollutants to air and water. Often times, nutrients are fed in excess of animal needs. In many cases, feeding strategies can be employed to reduce potential environmental impact.
To work with nutritional advisors and producers to put feed management principles into practice by demonstrating the impact that feed management can have.
ISUE has been involved in a national activity that has resulted in the approval of a revision to the standard for estimating nutrient excretion mass. This standard is used by state and federal agencies. Under the newly revised version, nutrient excretions are a function of feed inputs and animal performance (biological basis) rather than what had been used previously (bodyweight, a mathematical basis). The federal NRCS is now revising their handbook values to reflect the new ASAE standard. An additional activity includes working directly with a major feed company to understand pending environmental regulatory activity and how their involvement in the process and in implementation of feed management can make a difference.
A major feed company in the US will offer an 'environmentally-friendly' line of feeds to the swine and poultry industries, beginning in 2006. Continued training of this company's staff by ISUE personnel will occur in late 2005 and throughout 2006.
