Abstract: Antibiotics have long been used at sub-therapeutic levels to control incidences of post-weaning diarrhea and to improve growth performance in pigs. However, the current trend world-wide is to eliminate the use of in-feed antibiotics due to increased public concerns over the spread of antibiotic resistance in bacterial pathogens, which poses a threat to public health. Alternatives to in-feed antibiotics are needed. Thymol essential oil exhibits strong in vitro antibacterial activity; however; direct inclusion of essential oils to pig feeds has limited efficacy due to their high volatility, low stability during feed processing, interactions with other feed components and poor availability in lower gut. To solve these problems, we developed lipid matrix beads using thymol and a fatty acid with incorporation of 2% polysaccharides via a melt-granulation technique. Laurie acid was identified as a suitable carrier for thymol.
