Agriculture 1115 – Foundations for College Success
This course is designed to facilitate skill acquisition such as study skills, reading skills, note-taking skills, test taking skills and time management strategies for students transitioning from high school to university learning. Students complete self assessment exercises to better understand their personality, learning style and career interests. Students are introduced to student services across the College of Agriculture, Food and Natural Resources as well as resources available at the MU Library and Student Success Center. The course meets weekly in two sections for lecture followed by a small group discussion section. The small group discussion section is mentored by outstanding teaching faculty from across CAFNR. (Syllabus, learning objectives and example assignments/exams are included).
Animal Science 1011 - Introduction to Animal Science
Team-taught freshman level course that introduces students to the principles of the major scientific principles related to the disciplines of physiology, reproductive physiology, genetics, nutrition, environmental physiology and animal health. Course is taught each fall as a large lecture (average enrollment ranges from 140 to 200 students) that meets three times a week. A small group discussion – mini-lab was added that allows graduate student teaching assistants to meet with small discussion sections to discuss principles, conduct demonstrations that involve student participation that allows students to have a “hands-on” learning experience to compliment lecture. A course web page has been developed to support instruction and facilitate communication between course instructors and students. I am responsible for helping students learn material pertaining to nutrition. This section of the course includes discussion of basic principles of nutrition, classes of nutrients and feedstuffs, nutrient analysis, and a comparative overview of digestive physiology. I incorporate real world scenarios to make the basic principles pertinent and important to the students. I have taught this course from 1994 to present. (Syllabus, learning objectives and example assignments/exams are included).
Animal Science 1065 – Laboratory Practicum
This course is a team-taught introductory course for Animal Science freshmen. I am responsible for labs on the care and management of dairy cattle. The class is taught fall and winter semester with four lab sections meeting Monday and Wednesday or Tuesday and Thursday from 11 to 1:50 or 2:00 to 4:50 with a large group section on two Fridays. I have developed milking management and reproduction physiology laboratories stressing active student participation. The average enrollment is approximately 90 students each semester. I have taught this course from 1996 to present.
Sophomore level course that is required of all Animal Science majors and was developed to fulfill the campus general education requirement. The overall objective of the course is to introduce students to key issues facing animal agriculture. Assignments focus on reading current publications associated with issues affecting animal agriculture and include topics such as: animal rights – animal welfare; corporate farms – family farm – sustainable agriculture; food safety – BSE – biotechnology – antibiotic resistance; animal waste – nutrient management. Students identify core issues and the stakeholders for each issue. Invited speakers present opposing points of view to allow students to develop an appreciation for the complex opinions held by society. This course is a writing intensive course and requires freshman English and sophomore standing as a pre-requisite. A significant research paper is required and involves two revisions and peer editing. The course has been changed from a 2 to a 3 credit hour course and is taught each winter semester with an average enrollment of 80 students per term. (Syllabus is included).
Animal Science 2165 – Ruminant Production
This sophomore level course introduces students to the principles of dairy and beef cattle management. I developed the dairy section of this course and teach the first eight weeks of the semester. Key fundamentals of management systems involving milk marketing and dairy cattle management. Animal management focuses on the areas of systems for the growth and development of calves and heifers, reproductive management, breeding and genetic systems, DHIA production records, milk quality, mammary gland health, and milking management, nutritional management systems. A web page has also been designed for this course. In particular, virtual tours of dairy farm management systems are available for the students to complete in helping them better visualize the concepts discussed in class. The dairy section culminates in a take home exam requiring students to evaluate the production records of dairy cows managed as part of the University of Missouri Research Dairy Farm. The course has an average enrollment of 150 students per semester. It is offered in two sections to facilitate discussion between instructors and students. (Syllabus, learning objectives and example assignments/exams are included).
This course was developed for advanced undergraduates and graduate students interested in learning in greater depth the process of critically evaluating a dairy farm management system. Course utilizes case studies to allow students to apply knowledge and understanding developed in previous classes in the evaluation of dairy farm management systems. Course work includes extensive use of computer programs and required both oral and written reports. Course included farm consultation visit for students to evaluate cooperating commercial farms. The course is a 2 credit hour class and is taught based on demand with enrollment varying from 4 to 7 students.
Topics in Animal Science: Lipid Digestion and Metabolism in Ruminants.
Graduate level course that was a survey of current scientific literature pertaining to the utilization of lipids in diets fed to ruminants. The course is taught during summer session based on demand and interest among the animal nutrition graduate students in the Animal Sciences Unit. The course is a 2 credit course and enrollment has a range of 3 to 5 students.

I. Interaction of Nutrients in Diets of Lactating Dairy Cattle.
Feed costs represent fifty to sixty percent of the costs of production on commercial dairy operations. The proximity of the midwestern dairy industry to grain production and processing industries allows farm management to utilize a diverse blend of by-product feedstuffs. In addition to feed costs, milk protein has become an important economic variable. A shift in milk component pricing reflects a shift in dairy product consumption patterns. Therefore, strategies to control feed costs while optimizing milk and milk protein production have been studied.
By-product feeds can be used as an economical substitution in the diet. Many of these by-product feeds contain a high content of structural carbohydrates. The effects of combining several fibrous by-product feeds is not understood. In addition, the interaction of these combinations with other nutrients is also poorly understood. Therefore, a series of studies have been conducted to investigate the influence of diets containing high fiber (from fibrous by-product feeds) on milk production. Furthermore, rumen-protected amino acids (a new technology available in ruminant nutrition) have been used in comparison with traditional rumen escape proteins. The objectives of research activities in this area have been to evaluate interactions of nutrient levels and sources on milk production by dairy cattle.
A. Effect of diets containing high fiber from fibrous by-product feeds on milk production and composition, dry matter intake, and body weight changes.
B. Dietary factors that influence microbial degradability of dietary dry matter, crude protein/amino acids, and fiber.
C. Effect of undegraded intake protein and rumen-escape amino acids on milk production and composition of dairy cows fed high fat diets.
D. Strategic use of fibrous by-product feedstuffs with yeast culture to enhance rumen fermentation during the transition period.
II. Effect of Nutrition and Environment on Animal Health and Production.
Optimal animal performance and resulting farm profitability are essential for sustainability of the dairy farm enterprise. Mastitis (mammary gland infection) results in average losses of an estimated $200 per cow per year in the nation's dairy industry. Research has been conducted to define the relationship between mineral nutrition and animal health.
In addition to mammary gland health, the effects of heat stress on animal performance has also been studied. Heat stress can result in significant losses in production and increased risk of health problems. Therefore, management strategies to ameliorate the adverse effects of heat stress have been investigated. The objectives of this research have been to compare nutritional with other management practices to minimize disease and the effects of heat stress.
A. Effect of organic zinc supplementation on mammary gland health.
B. Interaction of young stock housing system and heat stress.
C. Niacin as a modulator of heat stress in mature lactating dairy cattle.
D. Strategic cooling of high producing dairy cattle
E. Gene expression in heat stressed dairy cattle
III. Interactions of Nutritional Status and Reproductive Performance.
Collaborative efforts with Food for 21st Century reproductive physiology faculty have been developed to study the effects of nutrition on reproductive performance of lactating dairy cattle. The primary emphasis has been placed on the influence of energy balance on ovarian function. These efforts have also included measuring the impact of heat stress on energy balance and reproductive function of lactating dairy cattle. The objectives of this research has been to identify the impact on periparturient nutrition on reproductive function of the high producing dairy cow.
Effect of supplemental fat on reproduction
Use of soybeans as fatty acid supplement for the periparturient dairy cow
Use of rumen protected choline to improve metabolic status of the periparturient dairy cow.
Effect of feeding soybeans to heat stressed dairy cows on thermal balance, lipid balance and reproduction.
The effects of using anionic salts as dietary supplement or delivered by oral bolus on calcium and energy balance of dairy cattle during the periparturient period.

Description of Programs
Dr. Spain was one of two state extension specialists with responsibilities for dairy cattle extension education programs. Dr. Spain's initial appointment (January 1, 1990) was 80% Extension and was modified to 60% Extension in July, 1992. Extension responsibilities included dairy cattle nutrition management and production management records analysis. In this capacity, Dr. Spain provided training, advice, and support for eight University Extension Dairy Specialists located throughout the state. Dr. Spain served as an ex-officio board member for the Missouri Dairy Herd Improvement Federation State Board of Directors. In addition, he served as an integral member of the Commercial Agriculture Dairy Focus Team. Dr. Spain has developed a number of completed and on-going extension education programs that are structured to improve production efficiency of commercial dairy producers. The overall objective of these programs has been to improve the profitability and competitiveness of Missouri's dairy farms through improved nutrition management that lowers feed costs and improved management decisions through better utilization of production management records. These programs are outlined below.
I. Computerized Diet Formulation for Dairy Cattle.
Formulation of diets for dairy cattle requires the use of computer technology. Since January, 1990, Dr. Spain trained area extension specialists, veterinarians, feed industry personnel, and dairy farm managers to use the DAIR4 ration evaluation computer program.
II. Nutrition Short courses and Video Lectures.
Successful application of computerized ration formulation requires a working understanding of nutritional principles. Dr. Spain worked with area dairy specialists to develop and conduct Nutrition Short courses. The short course format allowed complex nutrition topics to be covered in sufficient detail for student-clients to develop a basic understanding of nutrition and nutrition management.
In an effort to provide more extensive lecture support, a series of video lectures were produced for use in Nutrition Short courses. The video lectures were a joint effort of Dr. Spain and state and regional extension specialists.
III. Body Condition Scoring Clinic.
In the format of 4-H/FFA judging clinics, a Body Condition Scoring (BCS) Clinic was held at Ozark Empire Fairground in October, 1990. Dr. G.M. Jones, developer of BCS System, provided instruction for producer's, veterinarians, and area extension specialists in technical aspects of BCS. Total attendance exceeded 130 with attendees receiving published proceedings.
IV. Ruminant Nutrition Symposium.
Dr. Spain coordinated a seminar for professional nutritionists, faculty, graduate students and area specialists. Dr. Chuck Schwab, nationally recognized amino acid nutritionist (University of New Hampshire), presented discussion of amino acid requirements of lactating dairy cows. Attendance included more than 50 scientists and feed industry personnel. Nutritionists representing six major feed companies were present.
V. Nutritional Management of the Dairy Herd for Improved Efficiency and Profitability.
More than eighty talks dealing with topics in nutrition management have been given across Missouri to dairy producer groups in 36 counties covering 8 regions. Topics discussed at numerous regional producer meetings have been subjects identified by county/regional dairy producer advisory groups. Average attendance has been more than 40 participants per meeting.
VI. In-Service Education for Area Specialists.
Dr. Spain has been involved in several ISE's for area dairy, livestock, and farm management specialists. These programs have included the introduction of new concepts and communicating results of ongoing research activities at MU.

VII. Dairy Herd Improvement Records Utilization.
Dr. Spain has worked with the Missouri DHIA State Manager and Federation Board of Directors in an advisory capacity. During the transition to the new records system provided by the Dairy Records Processing Center at Raleigh, Dr. Spain worked with the state manager in conducting training sessions for producers and DHIA supervisors. Dr. Spain also works in cooperative projects under the Memorandum of Understanding with the Dairy Records Processing Center personnel. Since January, 1997, Missouri DHIA and Kentucky Dairy Records have worked as a merged organization, Mid-South Dairy Records. Dr. Spain continues to represent Missouri Outreach and Extension as an ex-officio advisor to the board.
A. Computer training for use and analysis of DHIA records.
Dr. Spain coordinated meeting for regional dairy specialists in the use of computer programs. Personnel from the Dairy Records Processing Center at Raleigh conducted a two day workshop including a session held at the Extension Computer Technology Center computer lab for hands-on training.
B. Computer Training Up-date
Dr. Spain coordinated a computer software workshop for state and regional dairy specialists. Missouri DHIA state management personnel conducted a day long hands-on workshop to introduce improvements and enhancements of DHIA software. Workshop was conducted in two locations.
C. DHIA Herdbook Clinics.
Dr. Spain has introduced annual herdbook clinics held in late fall of each year. Clinics have been held in 6 regions since 1993. These clinics offer producers an opportunity to evaluate production management records on an annual up- date basis. New concepts are introduced and other important concepts reviewed.
VIII. Dairy Nutrition Cow Colleges
Dr. Spain worked with state and regional dairy specialist to plan and conduct two day nutrition management short-courses at four locations in the state. Attendees received training in basic nutrition management concepts with conference proceedings provided. Evening meetings were held for allied industry professionals (i.e. veterinarians, nutritional consultants) for lectures on advanced nutrition management topics. These meetings are designed for above average managers and allied industry personnel.
In 1997, the Cow College was changed to a one day seminar to facilitate attendance by owner/managers of smaller units that had insufficient labor to allow attendance to a two day seminar. The Cow College has also become a partnered program with the Missouri Dairy Association. In 1998, the program will include two outside speakers, Dr. Mike Hutjens and Dr. Bill Bickert. Outside speaker honoraria were sponsored by industry with travel expenses and proceedings costs sponsored by the Missouri Dairy Association.
IX. Commercial Agriculture Dairy Focus Team.
Dr. Spain has worked as an integral part of the multi-discipline dairy focus team in the Commercial Agriculture program. This includes Commercial Dairy Institute planning committee in 1990 to 1999. Dr. Spain worked with focus team members to develop the Commercial Ag Dairy Plan which includes a dynamic production and economic computer simulation program.
X. Heart of America Dairy Management Conference
Dr. Spain co-chaired a multi-state collaborative effort with extension faculty from Kansas State University. The conference was a joint effort with the major feed manufacturers serving Missouri and Kansas. With more than 150 allied industry representatives in attendance, speakers from 6 six states gave presentations on a wide range of management topics.
