# NWS is affecting both sides of border | Western Livestock Journal

> New World screwworm moved north in Mexico and closed the U.S.-Mexico border to live cattle in July 2025. Feedyards in Texas that rely on Mexican cattle are running at around 70% of capacity, and Mexican cattle are selling at about half their usual price.

## Why it matters

The closure cuts feeder cattle supply into U.S. feedlots, which supports feeder prices. Excess cattle on the Mexican side are depressing local values.
