Roger J. Lien is an Associate Professor in the Auburn University Poultry Science Department and is also the Department's Undergraduate Program Coordinator. He directs advising, recruiting, and curriculum development, assists with scholarship and internship programs, is the Advisor to the student Poultry Science Club, and facilitates interaction between impending graduates and employers. His research is directed at improving the physiological and economic performance of broiler and broiler breeder chickens. He also teaches two of the Department's Undergraduate Courses.

EDUCATION:

1988-89 - Post Doc Research Assoc, Reproductive Physiology, Univ of Minnesota
1988 - Ph.D., Physiology, North Carolina State University
1984 - M.S., Poultry Science, Texas A&M University
1980 - B.S., Wildlife and Fisheries Science, Texas A&M University

TEACHING / INSTRUCTION:

Dr. Lien is extensively involved in establishing contact with High School and Junior College students that may be interested in majoring in Poultry Science or the Poultry Science Pre-Vet option at Auburn. He advises students on preparing academically to come to Auburn, applying for admission, applying for scholarships, finding part-time employment, and obtaining internships. He coordinates the Department's conduct of the High School FFA Poultry Career Development Event Program each spring. He works closely with High School and Junior College teachers and counselors to help them help their students to attend Auburn University (hopefully in Poultry Science!). Dr. Lien is in charge of the updating and improvement of the Department curricula to best meet our student's and their employer's needs. He is also a member of the Department Scholarship and Internship Committees and is committed to maximizing their benefits to our students and teaches the following two classes:

POUL 3030 - Commercial Poultry Production
POUL 3150 - Poultry Physiology

RESEARCH:

Dr. Lien's research is focused on improving feeding, lighting, and management programs for broiler and broiler breeder chickens. Experiments are conducted at the Auburn University Poultry Research Unit in an environmentally controlled light tight facility. In each experiment, the influence of different feeding, lighting, or environmental treatments on growth or reproduction is determined. Production, physiological and economic parameters are monitored. Data are typically collected or calculated on body weight, uniformity, nutrient intake, body conformation, skeletal development, carcass composition, carcass parts yields, molting, sexual maturation, egg production, egg weight, eggshell quality, fertility, hatchability, and production costs. Most research is conducted in cooperation with Drs. Joe Hess, an Extension Poultry Nutritionist, Wallace Berry, another Poultry Physiologist, and Sarge Bilgili, an Extension Poultry Processing Specialist. None of the research could be completed without the able assistance of Mr. Frank Dillman (Ag Program Specialist), graduate students, and the extensive involvement of undergraduate research assistants.
