Probiotic feed additive, in place of antibiotics, found to boost growth and health in poultry

Antimicrobial resistance is an increasingly serious threat for public health, and the use of antimicrobials in livestock feed has been a major contributing factor in the emergence and spread of antimicrobial resistance to many drugs, according to the U.S. National Institutes of Health. The poultry industry is evolving toward antibiotic-free production to meet market demands and decelerate the spread, and Penn State researchers are helping to identify and better understand alternative approaches.
