A foal was lost on May 26, according to the sitrep for the week ending May 27.
The count for Day 1 was changed from ten to nine, dropping a foal that was originally thought to be part of the outbreak.
That leaves the total at 145.
All fatalities have occurred in pens occupied by the West Douglas horses, displaced from their home range by privately owned livestock.
Approximately 17% were foals.
Previous reports were posted to the Colorado HMA page.
Findings from an internal audit have been released to the public.
