Livestock producers and others around the country will have an opportunity to learn the latest on feeding strategies to reduce animal manure emissions during a Jan. 16 webcast featuring a Virginia Tech dairy scientist. The Livestock and Poultry Environmental (LPE) Learning Center of eXtension is producing the free webcast.

eXtension is an educational partnership comprised of land-grant universities across the country. Virginia Cooperative Extension is a partner in eXtension.

Four researchers will discuss economic and research data from field trials and the implications for different feeding strategies to reduce animal manure air emissions. They include

  • Andy Cole, USDA-ARS research scientist at Bushland, Texas, researches the effects of diet and management on nutrient excretion, ammonia emissions, and methane emissions of finishing beef cattle.
  • Mark Hannigan, associate professor of dairy science at Virginia Tech, focuses on regulating energy and nitrogen metabolism in ruminant animals and reducing ammonia emissions from manure through reduced urinary nitrogen output.
  • Alex Hristov of Pennsylvania State University studies improved efficiency of nitrogen use in dairy cows.
  • Scott Carter of Oklahoma State University conducts research about swine nutrition.

The Friday, Jan. 16, session begins at 2:30 p.m. The webcast meeting room opens 15 minutes before the start time. View the webcast online.

The webcast is one of a series of monthly Web broadcasts hosted by the LPE Learning Center, an information resource developed by more than 150 experts from land-grant universities, agencies, and other organizations. The center is part of the national eXtension interactive Web resource customized with links to local Extension websites.

The LPE Learning Center advocates that individuals involved in public policy issues, animal production, and delivery of technical services for animal producers should have on-demand access to the nation's best science-based resources.

eXtension is an educational partnership helping Americans improve their lives with access to timely, objective, research-based information and educational opportunities. Land-grant universities were founded on the ideals that higher education should be accessible to all, that colleges should teach liberal and practical subjects and share knowledge with people throughout their states.
