Abstract
A tool called the Transition Cow Index (TCI) has been developed to objectively evaluate the effectiveness of transition cow management at the herd level. Fourteen factors from the historical Dairy Herd Improvement Association (DHIA) record of each individual cow are used to predict her milk yield and projection at her first test date, a date that frequently overlaps with fresh cow disease periods. Deviations from her expected milk yield are calculated and used at the herd level to evaluate the overall effectiveness of transition cow management programs. TCI offers dairy managers and consultants an objective tool to benchmark current programs and monitor the effectiveness of interventions.
