Maintaining optimum environments in poultry houses is critical to achieving maximum performances of commercial flocks of poultry. Mr. Czarick and Dr. Fairchild are involved through a team effort in an ongoing research and demonstrational program to reduce energy requirements and to improve ventilation for poultry production facilities.

Ph.D, Physiology, North Carolina State University

M.S., Physiology, North Carolina State University

B.S., Animal Science, North Carolina State University

B.S., Poultry Science, North Carolina State University

Research Interests

Broiler management including air quality, energy conservation, lighting programs, and water consumption and quality

Academic Program

Extension education responsibilities include areas of broiler management and production. Other activities include preparation of and participation in 4H and FFA poultry judging contests, as well as contributing to programs that assist county extension personnel.

Research programs focus on the effect that management has on broiler physiology and production. The purpose of this research is to examine new technologies that could be adapted to improve broiler production.

Teaching responsibilities include POUL 4010 Advance Poultry Production.
