  • Genetic improvement in dairy cattle productivity has created a constellation of periparturient disease problems. We employ an integrated approach to understand transition cow disease pathogenesis. The goal is to improve dairy cattle health, productivity and profitability by exploiting advances in bovine genomics and knowledge of the role of metabolic, inflammatory and gastrointestinal elements in disease susceptibility. Design and evaluation of StepMetrixTM system for the diagnosis of lameness in dairy cattle.
