Education Program. We kick started our first grad class with a Breeder Mgmt. seminar featuring Dr. Keith Bramwell (U of A). If you missed that oppor-tunity, there are plenty more classes available including a Poultry Federa-tion Grower Symposium in April. For class information and fact sheets visit your local County Extension Of-fice or visit us online at poultrywaste.okstate.edu where you can also obtain an electronic version of our newsletter. Josh Payne, Ph.D. Area Animal Waste Management Specialist Editor’s Column poultrywaste.okstate.edu Poultry litter consists of manure, bedding material and other components such as feathers and soil. In commercial broiler production, wood shavings and rice hulls are commonly used as bedding added to the poultry house floor and utilized for raising five to six flocks on a single placement prior to complete cleanout. The houses are usually “caked-out” (removal of denser or wetter areas) between flocks. Proper ventilation to keep litter dry and the use of litter amendments are two common practices which help control ammonia volatilization, thus reducing the amount of litter N lost. This has been the traditional approach for broiler house litter management. Broiler litter from a complete house cleanout managed in this manner usually tests approximately 60-60-50, N-P-K, lbs/ton. Non-traditional litter management approaches such as in-house windrowing and partial house cleanout have become more common with some poultry producers. Both of these methods are aimed at re-using bedding material to save costs on replacement bedding. In-house windrowing is a process of forming litter into windrows in between flocks. If properly managed, high temperatures are achieved due to microbial activity within the windrow which can effectively reduce litter pathogen populations and disease risks. These increased temperatures created by windrowing can also lead to increased ammonia volatilization during and following the windrowing process. Although not well documented, this may impact litter N content.

Recently, both coun-tries have concluded new agreements, effective March 15, 2012, which provide new market access while leveling the playing field for US auto manufacturers and workers. For agricultural products, the agreement will either eliminate or phase out tariffs and quotas creating new opportunities for US farm-ers and ranchers seeking export to the world’s 12th largest economy. It is anticipated that US beef, pork and poultry exports to South Korea will increase providing US agriculture increased market access. Recently, a study group consisting of South Korean government, academic and industry officials visited the US to learn more about US commercial poultry production. The trip objectives were to foster new relationships with US government, academic and industry officials and discuss future trade issues between the US and South Korea. The group, hosted by OSU, was given an overview of US poultry production with an emphasis on the economics and issues surrounding regional production. In Arkan-sas, poultry production ranks as the top agricultural revenue generator while in Oklahoma poultry ranks 2nd in agricultural revenue. The visit also included meetings with University of Arkansas faculty, Tyson representatives and commercial poultry producers. Following their visit to Oklahoma and Arkansas, the South Korean group traveled to Washington, DC, to meet with USDA representatives. Pictured are the South Korean delegates; Drs. Josh Payne and Chanjin Chung (OSU); and Drs. Susan Watkins and Dustan Clark (U of A) during a visit to the Center of Excellence for Poultry Science in Fayetteville, AR. 1 Volume 2 Issue March 2012 Oklahoma State University, in compliance with Title VI and VII of the Civil Rights Act of 1964, Executive Order 11246 as amended, Title IX of the Education Amendments of 1972, Americans with Disabilities Act of 1990, and other federal laws and regulations, does not discriminate on the basis of race, color, national origin, gender, age, religion, disability, or status as a veteran in any of its policies, practices or procedures.
