Bacterial supplement could help young pigs fight disease

In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.

"We could potentially strengthen the immune system by providing this bacterium to animals at a stage when they are in need of additional energy," said Janet Donaldson, assistant professor in Biological Sciences Mississippi State University. "By providing an alternative energy source, the pigs are most likely going to be able to fight off infections more efficiently."
