DELMARVA — Cattle producers across the region may need to prepare for a parasitic threat most have never encountered. The New World screwworm was completely eliminated from the United States in 1966, meaning today’s ranchers have no direct experience managing this larval infestation. Livestock officials are urging producers to stay informed about warning signs and response protocols.
As summer approaches, monitoring for heat stress in herds becomes increasingly critical. Cattle show warning signs gradually, starting with minor behavioral shifts well before serious symptoms appear. By the time heavy breathing with an open mouth or sluggish behavior becomes visible, productivity declines may have already taken hold.
Markets
Livestock futures dropped Tuesday at the Chicago exchange. Live cattle for August settlement fell $0.95 to close at $239.65. Feeder cattle saw steeper losses, with August contracts down $3.12 to finish at $348.42.
Locally, corn at Laurel Grain Company in Laurel, Delaware is bringing $4.84 a bushel for July delivery. Soybeans are at $11.09 for July.
Forecast
Expect sunny skies today with a high of 75° and light northeast winds. Tonight stays clear with lows around 61°. Thursday looks nearly identical, sunny and 76°. Dry conditions continue through the weekend.
