Birth control for wild horses could prevent roundups to thin herd


FARGO - An experiment involving birth control for the wild horses in Theodore Roosevelt National Park in western North Dakota is about to get a boost.

Researchers have been testing a vaccine on some of the mares in the wild horse herd in the park's South Unit since 2009.

The immuno-contraceptive vaccine is intended to keep treated mares from ovulating, therefore helping to control the population of the herd.
