In August 2026, the national average transaction price of fat Simmental bulls exceeded 30.67 yuan per kilogram, soaring by 17.29% year‑on‑year and hitting a new high for the year. As cattle prices climbed back above the 30‑yuan mark, the capital market rallied in response to the cattle‑market upturn, sparking widespread jubilation among livestock producers. However, if you regard this merely as a "reversal of the cattle cycle", you are grossly underestimating what is unfolding.

The core logic behind the occurrence of diarrhea in beef cattle due to high concentrate feed is as follows: High starch disrupts the rumen microecological balance → Undigested substances enter the intestine → Abnormal posterior intestinal fermentation and increased osmotic pressure → Disruption of intestinal function → Diarrhea. This process involves the interaction of multiple links, ultimately leading to symptoms such as soft feces or diarrhea in beef cattle.
