Description
Rudney da Silva Maia Júnior and colleagues link blood measures before slaughter to final meat pH in beef cattle in a 2026 study. Dark, firm and dry beef is a costly defect tied to stress that drains muscle energy stores before slaughter. Nellore cattle, common in Brazil, react strongly to handling, which raises concern. The team compared blood glucose readings, enzyme activity and age estimates with the pH reached after slaughter.
Activity of the enzyme lactate dehydrogenase tracked with final pH, and age judged from teeth also correlated. Glucose from a portable meter did not match laboratory values or predict pH. Patterns differed between castrated and intact males. Practical screening before slaughter may need laboratory-grade measures rather than quick meter readings.
