CME live and feeder cattle contracts experienced a decline on Thursday due to weakness in equities, a strong dollar, and technical trading. Lean hog futures also saw a slight decrease as market players perceived hogs as overbought. The Federal Reserve's economic projections and the anticipated slowdown of rate cuts contributed to the steepest US stock selloff in months. The US-Mexico border's closure to cattle imports due to the discovery of New World screwworm in southern Mexico also impacted the cattle market. A Reuters poll anticipated US November cattle placements to be 5.1% lower than the previous year, and a Reuters survey predicted the US hog herd size to be similar to the previous year.
