In a rare long-term public study that compared the effects of phytochemicals from rosemary and oregano with antibiotic growth promoters, animal scientists with the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture, found that the natural agents given to weaned pigs supported favourable gut health and growth performance later in their lives by preserving microbial diversity to improve nutrient utilization.
In the search to replace antibiotic growth promoters with effective alternatives in modern swine production, plant-based essential oils are showing potential to provide lasting benefits. In a rare long-term public study that compared the effects of phytochemicals from rosemary and oregano with antibiotic growth promoters, animal scientists with the Arkansas Agricultural Experiment Station found that the natural agents given to weaned pigs supported favorable gut health and growth performance later in their lives by preserving microbial diversity to improve nutrient utilization.
“This study allowed us to look at the lifetime impact of phytochemical exposures,” said Tsungcheng “TC” Tsai, Ph.D., a program associate in the Department of Animal Science for the experiment station, the research arm of the University of Arkansas System Division of Agriculture. Tsai is the corresponding author of the study published in the journal Animal Research and One Health.
