Short productive lifespans in intensive livestock production reflect poor welfare and reduce sustainability. Breeding and management that support longer lives improve both welfare and farm economics.
Livestock longevity is a welfare indicator as much as an economic metric. Cows that survive longer are cows that have avoided the disease and injury events that cause premature culling — lameness, mastitis, and metabolic disease are the primary culprits. Short productive lifespans therefore indicate high welfare failure rates during the production period. Breeding for longevity selects for animals with better immune function, structural soundness, and reproductive efficiency — traits that correlate with better welfare experience throughout the productive lifetime. The Nordic countries have demonstrated that breeding programs prioritizing longevity alongside production produce cows that live longer, need less antibiotic treatment, and have better welfare indicators than comparably productive breeds selected only for yield.
