Overview

Research reveals how milking intensity impacts milk yield and productive use in simmental first-calf heifers.

Key Points

  • Higher milking intensity correlated with increased longevity in simmental cows, extending productive life.
  • Cows with lower milk yield (4000–5000 kg) had a life expectancy increase of about 178 days compared to higher yield classes.
  • Cows yielding 7001 kg or more produced 20,317 kg of milk across fewer lactations, showcasing notable productivity.
  • Comparative evaluation showed significant milk yield advantages in first heifers of the highest productivity class.
