Introduction

Animal agriculture contributes more than 55% of the total annual agricultural income in North Carolina. The basis for all of animal agriculture is a dynamic feed milling industry that provides the nutrients essential for animal growth and reproduction. Sustainability of animal agriculture in North Carolina depends upon efficient feed utilization and minimization of environmental impact. The College of Agriculture and Life Sciences (CALS) at North Carolina State University (NC State) has embarked upon a Feed Milling Education Initiative to support this key industry. The College of Agriculture and Life Sciences Feed Milling Education Initiative is designed to develop well-educated men and women for leadership roles in the feed milling industry and to provide the underlying educational and research programs required to support a sustainable industry. The educational emphasis will be directed at undergraduate and graduate students as well as the needs of industry clientele currently working in our many feed mills.

Initiative Structure

The College of Agriculture and Life Sciences Feed Milling Education Initiative is comprised of the following three components:

• Academic Program for undergraduate and graduate students and industry clientele.
• Feed Mill Educational Unit to house the feed milling equipment and teaching site.
• Feed Milling Center to fund future educational and research projects.
• Capital Campaign to raise the funds required to complete the milling facilities.

Present Status

The Academic Program has been initiated with the approval of a Minor in Feed Milling effective Fall Semester 2001 and acceptance of several students into the minor. The basic structure that will house the Feed Mill Educational Unit at the Lake Wheeler Road Field Laboratory was completed in the Fall of 2003. The Feed Milling Center concept is currently under development.

Capital Campaign

To support the successful development of the Feed Milling Education Initiative, a Capital Campaign with a goal of raising $2 million in cash and equipment will be conducted over the three-year period from 2003-2006.                                                                                                                     Return to top.

General Perspective

Plans are well underway to convert the historic Yates Mill, pond, and wetlands adjacent to the Lake Wheeler Road Field Laboratory into a Wake County Ecological Park that has environmental education as its purpose.   The emphasis of this park will be on youth education with anticipated full involvement by the College of Agriculture and Life Sciences in this effort. The surrounding urban areas of Raleigh, Cary, Garner, and the Swift Creek-Middle Creek community continue to grow and create demands upon the undeveloped acreage of the Lake Wheeler Road Field Laboratory.   The Lake Wheeler Road Field Laboratory remains one of the few "open areas" in the Raleigh area.   Further, the fact that many educational programs dealing with agriculture are located there has provided the College of Agriculture and Life Sciences with a unique opportunity to develop a premiere educational program based upon the contributions of animal agriculture to the local environment and society and to showcase a harmonious interface of agriculture and urban life. The educational outreach will extend to students, agriculturalists, the scientific community, and the general public as a whole.

The Feed Mill Educational Unit is being planned as an integral part of the environmentally sound "mini-integration" involving present animal production and crop production units at the Lake Wheeler Road Field Laboratory, the Waste Processing Facility of the Animal & Poultry Waste Management Center, and other facilities and programs within the College of Agriculture and Life Sciences as outlined below.   It will serve as an excellent teaching model of good natural resource stewardship practices and how they can be combined with efficient, integrated and sustainable animal agriculture.

The Animal and Poultry Waste Management (A&PWM) Center provides a number of opportunities to coordinate activities with the Feed Mill Educational Unit.   One of the primary missions of the A&PWM Center is to develop methods to convert byproducts (animal mortalities, offal, hatchery wastes, plant components not normally harvested, etc.) into value-added coproducts for the animal or plant industries. Because such animal byproducts represent 30 percent of the total live weight of the animals produced, it is extremely important that recycling technologies be further developed. The extremely high temperatures produced during milling render the coproducts produced biologically safe for re-entry into the feed stream.

Development of an Academic Program in Feed Milling

Establishment of a new major degree program within the University of North Carolina system is a lengthy process. Due to monetary constraints any new major requires considerable justification regarding the need. Further, any new program, as well as continuing programs, must be constantly justified if the number of students graduating annually is low. This is presently the case for a number of degree programs in traditional agricultural areas. Therefore, a more logical way to proceed was to first develop a minor that could be used by students to receive academic training and certification in the specific topical area of feed milling. Development of the minor required the identification of courses that were presently being taught that could be applied to the topical area. In the case of feed milling there are a good number of courses currently available that have direct applicability. These are described in the text below. In addition, there has recently been developed a general survey course in feed milling that can serve as the initial core course. Collectively these courses will serve as the basic preparation for an actual feed milling work experience that can be structured within the External Learning Experience summer internship course. It is anticipated that a number of commercial feed mills will cooperate with the College of Agriculture and Life Sciences to provide these summer work experiences for our students. In the longer term, it is envisioned that interested feed milling enterprises may create full-time positions that can be filled on a rotating basis by Co-Op students.   This Co-Op model is used in other curricula at NC State.   The minor was approved effective Fall Semester 2001.

One weakness of the minor approach is the relatively low number of credit hours required. However, it is anticipated that this academic program will evolve rapidly in the direction of a feed milling “concentration” that will require a greater number of credit hours. This will ensure that students are exposed to a more complete program. A record of successful placement of graduates from the Feed Milling Minor in jobs with feed milling enterprises at competitive salaries will provide the necessary stimulus and justification for this evolution. A Feed Mill Management Concentration may be developed within any or all of the three present participating departments. Further, at least two more courses in Feed Milling will be needed along with a revision of present courses to adequately cover required materials. This would create a core curriculum of three courses and supporting courses. This will require the addition of a new faculty member specifically educated in the feed milling area.

An Undergraduate Inter-Departmental Minor in Feed Milling
in the College of Agriculture and Life Sciences

The Inter-Departmental Feed Mill Minor is especially important to the North Carolina agricultural economy.   Currently, there are limited educational programs in the United States that specifically provide a balanced program in animal feed milling technology and animal and poultry management. Currently, North Carolina is a leading animal feed producer with over 12 million tons of animal feed manufactured each year.   Modern feed mills are complex and technologically advanced, requiring well-educated graduates to manage them.   There is presently an acute shortage of such graduates that could be met by an appropriate educational program. The Inter-Departmental minor will allow students an opportunity to acquire the knowledge they need to enter this field while providing employers with a supply of much needed people. Students may consult the Departmental Teaching Coordinator in Animal Science, Biological and Agricultural Engineering or Poultry Science to initiate the minor program.   Students in this minor program, with the help of their primary faculty advisor, can also request advising assistance from a designated Departmental Feed Mill Minor advisor.   The student must submit an Application for a Minor to the Departmental Teaching Coordinator in Animal Science, Biological and Agricultural Engineering or Poultry Science.   These interdepartmental forms will be available in each departmental teaching coordinator’s offices. Students from other departments within the College of Agriculture and Life Sciences or the university as a whole may submit the necessary written materials through any of the three departments listed above.                                                                                                                                  Return to top.

Feed Milling Education Initiative Faculty Impacts

A new faculty position to provide leadership to the College of Agriculture and Life Sciences Feed Milling Education Initiative will be requested from the University of North Carolina System. The scope of the responsibilities of the faculty position will depend upon the feed mill facilities that can be developed. Financial support from the industry for this initiative would facilitate the timely development of this program that will have both on-campus and outreach impacts.

Outreach Programs for Industry Clientele

Workshops, distance education classes, and feed production schools utilizing the planned facilities are anticipated to serve the continuing education needs of the feed milling industry.

Feed Mill Educational Unit
Benefits and Educational Impacts

• This facility will provide animal researchers and teachers with a state-of-the-art facility within which to manufacture modern feeds for animals, thus positioning the College of Agriculture and Life Sciences as a leader in animal feed milling and nutrition research and education.  
• The program will attract external grant opportunities, contracts, and new types of milling equipment.
• The program will also help attract the best undergraduate and graduate students, faculty, and industry collaborators to the College of Agriculture and Life Sciences educational programs.  
• The facility will provide the backbone of an educational program designed to produce college graduates that are competent in feed mill management and to support a continuing education program for industry clientele.
• This facility will allow the College of Agriculture and Life Sciences to fully and efficiently utilize current animal research space and facilities to help maintain the diverse agricultural industry that has tremendous economic impact in all areas of our state.
• This facility will aid the development of uses for byproducts produced during the harvest of the more than 60 agricultural commodities grown in North Carolina.
• The facility will encourage the current industry trend towards precision animal nutrition that meets the nutritional requirements of animals while minimizing environmental impact.

Present Status

A comprehensive schematic plan was developed for the phased construction of a College of Agriculture and Life Sciences Feed Mill Educational Unit.   Approximately $2.4 million, appropriated by the 1997 legislative session of the North Carolina General Assembly and another $300,000 from the 2001 Bond Package, was available for construction of the basic structure. To maximize the effectiveness of these funds construction documents were developed for a basic mill structure and site work as a bid package separate from the milling facilities and equipment.   After several delays due to adverse weather and economic conditions, a general contractor was hired for construction of the buildings, infrastructure, and site work that was completed in the fall of 2003. Local millwrights, electricians, tradesmen, etc. will now be hired to install NC State purchased and/or industry-donated equipment when all the necessary equipment has been acquired. This strategy will require a longer period of construction than a turn-key job but will ensure that qualified contractors are responsible for the specialized as well as general requirements of this unique facility at the lowest possible cost. Further, direct purchasing of the milling infrastructure by NC State will hopefully maximize the possibilities for discounts, gifts-in-kind, and donations from vendors and supporters.   The North Carolina Agricultural Foundation will provide assistance to individuals or companies who would like to arrange a tax-advantaged contribution or gift-in-kind.                                                            Return to top.

Feed Mill Educational Unit Planning Priorities

The feed milling facility will be officially named the Feed Mill Educational Unit and as envisioned will meet a number of educational objectives for animal agriculture related programs such as:

• On campus instructional programs at the undergraduate and graduate levels in relation to feed formulation; feed manufacturing; mill design; mill operation and maintenance; mill safety; ingredient and finished feed quality assurance programs; specialty feed production; mill regulatory programs, etc.
• Production of relatively small batch precision feeds for research animals, as well as precision premixes and concentrates.
• Extension education programs including workshops and short courses for industry clientele.
• Educational programs for the general public.
• Research on certain aspects of feed manufacturing per se for the livestock and poultry industries.

Feed Mill Educational Unit Facility Design and Features

• The facility will include all of the normal components of a commercial mill.
• Provisions for a video surveillance system will be incorporated throughout the mill to allow viewing in a remote location and discussion of remote and micro processes.
• Quality assurance and quality control testing of ingredients and feeds produced will be an integral part of the overall mill arrangement.   Quality control procedures (i.e., ingredient and finished feed sampling, sample storage, sample testing) and regulatory compliance programs will need to be utilized in the day-to-day feed production processes, and demonstrated in the teaching programs.
• The milling processes involved will be subject to either semi-automation or manual operation, so that the teaching and/or research programs can utilize or demonstrate the unique aspects of each part of the system or of the system as a whole.
• Ruminants can utilize a number of coproduct feedstuffs developed from animal and other agricultural byproducts.   The basic feed mill, however, will not be designed to handle very bulky types of feed such as fodder, hay, silages, etc., but will be able to produce premixes and concentrates designed to be mixed with bulky or wet feeds in adjacent facilities.
• The mill design will incorporate both a small batch pilot facility and a main production facility.
• The physical plant for the mill will provide enough flexibility and room to allow for upgrading of the equipment, and the testing of new and experimental equipment and processes.
• Utility connections for the major equipment items will have usage monitoring incorporated into the design so that economic evaluations can be made for various processing techniques.
• Safety will be a major consideration in design, operation, and instruction.
• The facility will be capable of dispensing feeds into bags, bulk boxes, bulk bags, and bulk trucks.
• A unique split-level design with an upper Ingredient Level and lower Process Pit will position access to most operations at or below a floor level to facilitate operations and instructional activities.

College of Agriculture and Life Sciences Feed Production Requirements

A 150-ton per week capacity mill should meet the production needs of the College of Agriculture and Life Sciences animal units.   There will be nearly 100 unique feed formulas typically in use at any given time.   It is desired that the feed production needs be met in three working days per week, allowing two days per week for research, educational, and maintenance activities.

At the rear of this document there is a list of required equipment, elevations and diagrams that detail the Feed Mill Educational Unit plan.   A complete set of plans are available by request.

Feed Mill Educational Unit Planning Committee

The Feed Mill Educational Unit planning committee membership was developed from several constituencies that include the College of Agriculture and Life Sciences administration (CALS), Animal Science (ANS), Biological and Agricultural Engineering (BAE), Facilities Planning and Design (FPD), Poultry Science (PO), and University Field Laboratories (UFL).                                                                                                                                                  Return to top.

Feed Milling Center

A Feed Milling Center concept is currently under development. A Center within the University of North Carolina (UNC) system is organized from dues-paying members that comprise the Board of Directors for the Center. There are full members and associate members of the Center based upon the level of dues that are contributed. The full members make the decisions as to where member fees are spent to support educational and research initiatives. Full members share in semi-exclusive licenses to any new intellectual property as well.   In the case of the Feed Milling Center it is envisioned that there will be Academic, Extension Education, and Research initiatives that will involve issues such as new coursework, Extension Educational Programs and Workshops, and investigations of optimum feed milling practices.   Representatives of companies that make contributions at the Platinum recognition level will be invited to participate as Charter Members for a limited time in the Feed Milling Center at no cost. The Charter Members will help guide the development of the Feed Milling Center as members of the overall Advisory Board .

Advisory Board

To insure good communications and close working relationships with our industry clientele there will be an Advisory Board constituted that fairly represents the many interests that support and benefit from this Initiative. Companies that are Platinum level contributors will be invited to name a representative. The Advisory Board members will have an opportunity to provide direction and advice to the leadership of the Initiative.

Feed Milling Education Initiative Capital Campaign

To support the successful development of the Feed Milling Education Initiative a Capital Campaign with a goal of raising $1 million in cash as well as donations of equipment will be conducted over the three-year period from 2003-2006. Companies and individuals may make three-year pledges of cash donations or equipment through the North Carolina Agricultural Foundation that has pledged to match the first $750,000 of contributions from industry with $250,000. Companies that make contributions qualifying for the Platinum recognition level will be invited to have representation on the Advisory Board for the overall CALS Feed Mill Educational Initiative and to participate in the Feed Milling Center without charge for a limited time (to be determined).   This Charter Membership will become effective when the Center is approved by the UNC General Administration.
