Laura Greiner

Dr. Laura Greiner is an Associate Professor in the Department of Animal Science at Iowa State University, affiliated with the College of Agriculture and Life Sciences. Her research focuses on swine production challenges, particularly optimizing sow and suckling piglet nutrition to enhance liveability and performance. She leads the Cardinal Greiner Laboratory, which investigates dietary strategies to improve growth, health, and welfare in swine.

Her work spans amino acid and vitamin nutrition, feed formulation, and environmental impacts of livestock production. Collaborations include the College of Veterinary Medicine for studies on gut health, microbiota, and infectious challenges like E. coli. Dr. Greiner also explores educational tools to enhance soft skill development in science students.

Key research areas include:

• Soy-based diets and nutrient utilization
• Effects of branched-chain amino acids on lactation
• Vitamin D and arginine supplementation strategies
• Microbiota transplantation in sows
• Nutrient management for sustainable agriculture

Recent studies emphasize dietary adjustments to mitigate postpartum dysgalactia syndrome, optimize gilt growth rates, and reduce greenhouse gas emissions. No awards are listed, but her extensive publications reflect significant contributions to swine science.
