Profile
Alexa Johnson is originally from New Jersey and showed Hereford cattle for the 4-H for 8 years. After entering undergraduate studies at Virginia Tech, she found her new passion: chickens. She graduated Virginia Tech with a B.S. in Animal and Poultry Sciences and double minor in Public Health and Chemistry. Currently she is in her first year as a Master's student.
Research Interests
My current project is supplementing dietary oregano oil and evaluating the effects of production performance, welfare, behavior, and egg quality of laying hens.
I am assisting with running the study of replacing corn with 50% sorghum in the laying hen's diet and its impact on performance, egg quality, and welfare.
