Overview

Review reveals wide variation in longevity and replacement rate across cattle breeds, highlighting substantial genetic and environmental influences on lifetime productivity.

Key Points

Productive herd life and overall longevity vary substantially across dairy breeds, with native purebreds exhibiting longer lifespans than high-producing crossbred animals.
Replacement rate reached 74.72% in Frieswal cows, whereas Hariana cattle demonstrated a lower value of 48.40%, reflecting notable breed-specific differences in survivorship.
Review of breeding and lactation records synthesized lifetime trends in female calf culling rate, calf survival, and selective value across diverse native and crossbred herds.
Highlights that very low heritability estimates for calf mortality and replacement traits necessitate improved farm management rather than relying purely on selection.
