Dairy cows in intensive systems are culled after a few lactations due to health problems. Extending productive life through better welfare management benefits individual cows and farm economics simultaneously.
The short productive lives of intensive dairy cows reflect the cumulative welfare toll of high-yield production systems on individual animals. Cows culled at 4 to 5 years have experienced only a fraction of their natural lifespan and have been subject to repeated health problems that reduced their productive value to the point of replacement. Extending average productive life requires addressing the root causes of early culling: lameness, mastitis, and reproductive failure, all of which are substantially influenced by housing, management, and metabolic demand. Farms that achieve longer productive lives through better welfare management demonstrate that the goals of animal welfare and sustainable farming economics are aligned rather than opposed. Productive longevity is itself a welfare indicator worth tracking and rewarding in certification schemes.
