According to Michigan State University, the health status of swine herds should be among the top priorities for producers. Routine testing as part of a disease surveillance program is one method producers can use to improve the animal health status on hog farms.

“Producers looking for methods to easily increase the disease surveillance of their herds now have a lower cost option by collecting oral fluids for diagnostic testing. Oral fluids collection is done by the producer or farm employee and consists of simply hanging cotton ropes in the pen with the pigs. The pigs will explore the rope and chew on it, making it wet with saliva,” the university says.
