estimates from the integrator side approach 40-65% of their units infected. with ongoing infected units each week.   not too many farrowers in our area any more, but they have all contracted the disease. i'd say 70-85% of the finishers have got it.    prrs, while always a issue, seems to be coming in harder in the survivors of a farrower break .  my field man for one of the units we manage is just spinning circles.  company vet is talking about 4 strains now.
