Many states have regulations that require education for livestock producers and manure applicators. Adults that must attend these types of programs are often there solely to fulfill requirements and are not willing learners. While regulations may specify topics that must be addressed, most do not spell out teaching methods for these educational programs. It is well known that active learning promotes better retention of the material. In Nebraska however, these programs traditionally have been a combination of pre-recorded and live PowerPoint presentations as they are easier to develop and for educators that may not be manure experts to host. In recent years, the Nebraska Animal Manure Management team has been working to make their manure training program more interactive. This workshop highlights hands-on activities related to odor management, stockpiling and transporting manure, and equipment calibration. Audience members are encouraged to bring examples of hands-on activities that they are using to share with others.
The objective of this workshop is to encourage idea-sharing and collaboration in the development of activities and teaching techniques to better manure-related programming across state lines.
Lessons Learned in Nebraska in 2019
Hands-on activities have enhanced our programming in Nebraska by increasing participation during our training events. Participants can no longer sit back and watch videos (or pretend to watch videos). While we do not require testing to receive certification, we feel that we have really improved our program. We received more written feedback about the program in the “comments” section of the evaluation and often received praise for the instructors, which we had never gotten before. For most of the activities that we made major changes to, there was about a 20% improvement in the number of attendees that selected moderately high to significant knowledge improvement (3 or 4 on a scale of 0-4) when compared to the previous year’s evaluation results. Because on average we also had a 13% improvement for activities that were not drastically changed, this result may be skewed, but is still an interesting change. Looking at the data makes one wonder whether the increased interaction between and amongst participants and instructors resulted in higher marks overall because participants were generally more satisfied with the program – even those parts that were not changed.

Researchers and university specialists from USDA’s Meat Animal Research Center (USMARC), South Dakota State University, and Iowa State University recently finished a four-year study looking at mono-slope beef barns and how to improve cattle and environmental performance.
A research team worked for three years to gather baseline data for the levels of gas emissions from mono-slope beef barns. The study involved a total of four mono-slope beef barns in South Dakota and Iowa. Researchers also evaluated two different manure-handling systems to determine if there are any differences in gas emissions.
The results of that study are summarized in a eight-page publication “Air Quality in Mono-Slope Bedded Beef Barns“. They measured ammonia, hydrogen sulfide, methane, carbon dioxide, and nitrous oxide. The first three are the primary focus of the publication, since those are most commonly associated with beef feedlots. Also discussed are impacts of building orientation, manure-handling system, pen density, bedding type, and curtain opening (ventilation).
Beef Facilities Conference
Over 300 people attended the November, 2013 conference on beef confinement buildings held in Sioux Falls, South Dakota. The recordings and written papers are linked below.
Environmental and Regulatory Aspects of Beef Barns
The third presentation focuses on manure and nutrient production, and nutrient management for manure produced in these systems.
Capturing, managing, and using nutrients from the barn – pages 18-21
Producer Panel – Virtual Tours
Four producers shared aspects of their different building designs including ventilation, manure management, what works well, and things they would change. Their summaries are on pages 22-26 of the Beef Facilities Conference Proceedings.
Hoop buildings – one farm tour and a short synopsis of different building designs in use in Iowa
Mono-slope buildings – narrow and wide designs
Slatted floor barn (with rubber mats) – originally built without mats
Cattle Performance and Comfort In Beef Barns
University specialists compared feed intake, animal performance, carcass characteristics, and management considerations with barns compared to other systems. The page numbers next to each are the location of a companion written paper in the Beef Facilities Conference Proceedings.
It was standing room only as participants listened to station presentations in the alleyway of the mono-slope barn.
As part of the outreach plan for this project, a series of open houses were scheduled to inform cattle producers, regulatory and technical agency staff, Extension employees, service providers and legislative and local policy-makers about air quality management and manure and environmental issues with these facilities.
Over 200 people from Iowa, Minnesota, South Dakota and Nebraska attended the Mono-Slope Beef Barn Open House in June of 2011. The open house was hosted by Ron and Clayton Christensen of Royal, Iowa and featured barn and manure management, cost-sharing opportunities, the tri-state air quality project and environmental regulations.
The open house was organized by ISU Extension and Outreach, SDSU Ag and Biosystems Engineering, and the USDA Meat Animal Research Center at Clay Center, NE. Sponsors included Animal Medical Centers of Spencer, Clay County Cattlemen’s Association, Clay County Farm Bureau, Coalition to Support Iowa’s Farmers, Farm Credit Services of America -Emmetsburg, Spencer Ag Center and Spencer Chamber of Commerce Ag Committee.
A second open house was hosted in South Dakota in August of 2011. The open house was hosted by Goodwin Heritage Cattle Company, with approximately 125 people in attendance from South Dakota and neighboring states. Sponsors included Coteau Hills Cattlemen’s Association, Watertown Chamber of Commerce Ag Committee, SPN & Associates, Glacial Lakes Energy LLC., Landmark Builders Inc., South Dakota Farm Bureau, Ag United for South Dakota, Banner Associates and Form-A-Feed, Inc.
As a result of the two open houses:
95% had a better understanding of the air quality regulations and why this research is needed*
88% learned where they could find financial resources to construct a mono-slope barn*
89% had improved knowledge about how gases and dust are measured*
*Based on 19.7% participation in a short survey after each open house
A facility tour, Science Behind Environmental Policy, was held June 22, 2012 in NW Iowa. This tour was attended by state and federal legislators, state policy makers and stakeholders representing Extension and university specialists. Enthusiasm for research efforts was proclaimed by the legislators. See what they learned.
NW Iowa cattlemen listened to Mindy Spiehs, researcher with USDA ARS Meat Animal Research Center at Clay Center, share progress about the Tri-State Air Quality Project. The update and tour at the Christensen barn were part of a NW regional meeting sponsored by the Iowa Cattlemen’s Association on August 23, 2012.
Mindy Spiehs talks about the Tri-State Air Quality Project.
Waste to Worth Conference Presentations
In April, 2013 researchers presented air emissions results from this project at the Waste to Worth: Spreading Science and Solutions conference in Denver, CO. These proceedings include a short written paper, recording and links to additional information. The different aspects presented were:
There is growing interest in feeding cattle in bedded confinement buildings for a multitude of reasons including (but not limited to): performance advantages, limited space for open lots, and keeping manure dry as well as preventing feedlot run-off and reducing environmental concerns. Oftentimes these confined cattle are housed in mono-slope barns.
Mono-slope barns, by definition have only one slope to their roof and are usually naturally ventilated. They are typically positioned to take advantage of seasonal climatic conditions. This means in the northern hemisphere the higher side would be south-facing with the lower side to the north. This allows for shade in the summer and sun exposure in the winter. In bedded units, the bedding absorbs moisture and provides a softer surface for cattle to walk and lay on.
Comparing Confinement Farms with Conventional Feedlots
Shawn Shouse of Iowa State University compares
confinement systems to open lots for beef cattle.
While there are many advantages to mono-slope beef barns, the question that has been raised is: “What is the quality of air in these barns?”. A recent, on-going research project takes on this question.
