Abstract

A two-year study of the entire reproductive cycle of the cow, heat detection to calving, in well-managed Pennsylvania dairy herds was just completed. Objectives of the study were to collect and store significant individual animal and herd information in order to evaluate and problem-solve the management, nutritional, genetic, and infectious influences on reproductive performance. Stored data was used to (1) define expected reproductive performance standards and goals for Pennsylvania dairy operations and (2) develop a multidisciplinary approach to reproductive problem solving where performance does not measure up to these standards.
