Metabolic profiling through blood sampling allows early identification of nutritional and metabolic problems before clinical disease develops, improving cattle welfare outcomes.
Metabolic profiling enables welfare intervention at the subclinical stage, before the suffering of clinical metabolic disease occurs. Identifying herds with elevated NEFA or BHB levels in the transition period allows dietary and management adjustments that prevent clinical ketosis, milk fever, and displaced abomasum. The welfare benefit is the prevention of conditions that cause significant pain and debilitation. Blood sampling itself involves brief restraint and a needle stick — a transient welfare cost justified by the welfare protection it enables. Integrating metabolic profiling into routine transition cow management is a welfare investment with demonstrated return in reduced disease incidence.
