Objective—To test the hypothesis that dairy farms
certified in the Milk and Dairy Beef Quality Assurance
Program (QAP) were more likely to use prudent drug
management practices than farms that were not certified.
Sample Population—141 Michigan dairy farms of
which 74 were not certified in the QAP, 30 were involuntarily
certified, and 37 were voluntarily certified.
Procedure—Dairy producers completed a self-administered
questionnaire that focused on herd health
management, drug use, record keeping, personnel
management, and descriptive characteristics of their
farm during 1993. Separate multivariable logistic
regression models were developed to determine the
association of QAP certification with each of the management
Results—Results suggested that farms adopted specific
management practices irrespective of certification.
Many farms used visible identification and nonemergency
veterinary services and discussed residue
prevention with employees. Involuntary certification
was associated with maintenance of good written
treatment records and performance of on-farm drug
residue testing. Voluntary certification was weakly
associated with use of refrigerated drug storage.
Conclusions and Clinical Relevance—QAP certification
appeared to have been associated with the adoption
of only a few prudent drug use practices,
although QAP materials and framework were developed
to assist veterinarians in the promotion of disease
prevention, client communication, and residue
prevention practices on farms. Veterinary care would
benefit from the development and encouragement of
better record keeping on farms. (J Am Vet Med Assoc
