Costs of PRRSV in commercial production.
Proceedings of the ISU Swine Disease Conference for Swine Practitioners 2003: 172-173
This paper reports an example of analysis to estimate the impact of PRRSV on wean-to-finish performance in a multi-site production system in the American Midwest. Three types of status were attributed: status 0 to consistently weaning PRRSV-negative pigs, status 1 to consistently PRRSV-positive finishing pigs with minimal seroconversion to PRRSV evident in late nursery and status 2 to consistently PRRSV-positive nurseries. An increased margin per pig weaned of 2.12$ and 7.07$ was evaluated for status 0 pigs over status 1 and status pigs respectively.
