Current problems in dairy farming include particularly a frequent occurrence of health and fertility disorders that makes the herd reproduction more expensive and reduces the revenue from milk and breeding animal sales. The main goal of this project is to elaborate procedures for early detection and evaluation of causes of significant problems existing in dairy herds, and to develop methologies for their removal and prevention. The project implementation will be based on the evaluation of routinely collected data and parameters monitored in specific herds, and on newly developed indices that will increase the efficiency of dairy herd management evaluation.
