BULK TANK SURVEILLANCE PROGRAM FOR NEW YORK DAIRIES: USE OF BULK MILK ELISA TO PREDICT HERD-LEVEL PREVALENCE OF PARATUBERCULOSIS

摘要

The bulk tank surveillance program that Quality Milk Production Services (QMPS) has been developing in the last years encompasses monitoring for milk quality, mastitis pathogens, BVD virus and food safety pathogens. The framework developed for this project allows the addition of multiple other monitoring tools. One of these is the use of bulk milk monitoring using Mycobacterium Avium subspecies Paratuberculosis (MAP) Milk ELISA to determine the MAP infection status in dairy herds. To evaluate the value of this addition, we studied MAP infection status based on fecal culture of cows in the herd and used contemporary environmental samples to compare these two estimates of MAP infection to the bulk milk MAP ELISA titer.
