Technical Abstract: The objective of the current research was to determine if feeding citrus by-products D’Limonene (DL) and citrus molasses (MOL) would reduce the concentration and prevalence of Salmonella in weanling pigs experimentally infected with Salmonella Typhimurium. Twenty crossbred weanling pigs (avg. BW = 19.9 kg) were randomly assigned to one of four treatments: Control, low DL (1.5 mL / kg BW / d), high DL (3.0 mL / kg BW / d), and MOL (0.05 kg / BW /d). Treatments were administered via mixing with the feed twice daily with one half dose at each feeding. Fecal samples were collected twice daily and cultured for quantitative and qualitative determination of Salmonella using standard culture techniques. Upon study termination, pigs were euthanized and tissues from the rumen, ileum, cecum, spiral colon and rectum, as well as their respective luminal contents were collected. In addition, the popliteal and ileocecal lymph nodes, liver, spleen, and tonsils were collected for qualitative Salmonella culture. No significant treatment differences (P > 0.05) were found for fecal Salmonella prevalence or concentration between treatment groups throughout the 7-day collection period. Furthermore, no treatment (P > 0.05) differences were observed for any of the tissue or content samples collected. Salmonella was not cultured from the muscle bound, popliteal lymph node, but was cultured from the mesenteric ileo-cecal lymph nodes. Salmonella continues to represent significant animal and human health concerns and further research to find cost effective control measures is warranted.
