Antelope Roundup Day 22

The incident began on August 2.  Gather stats through August 23:

• Horses captured: 1,575, up from 1,491 on Day 20

Three foals were put down on Day 21 due to pre-existing conditions, raising the death rate to 0.6%.

Foals accounted for 18.4% of the horses gathered.  Of the adults, 42.2% were male and 57.8% were female.

Body condition scores were not reported.

Day 22 ended with 8 unaccounted-for animals.

The gap between males and females continues to increase.  The observed percentages can’t be produced by a random process centered at 50% males / 50% females with n = 1,285 adults.  The expected range of variation is found with basic statistical formulas.

To date, 542 stallions have been taken from the Complex, with 743 mares.  The sex of the foals was not provided.
