AI Article Synopsis
- Calf mortality serves as a crucial indicator of health and welfare in dairy farms, but challenges like unreliable data and inconsistent definitions hinder effective monitoring.
- Research shows that a lack of standardization in defining calf mortality complicates comparisons across different farms and studies.
- The review aims to assess risk factors related to calf mortality and highlights the need for better data collection and management strategies to prevent calf deaths.
Article Abstract
Calf mortality can be used as an indicator of animal health and welfare on dairy farms. However, several challenges surround the estimation and reporting of this metric, specifically: (1) lack of records or reliable data, (2) methods of data collection, and (3) inconsistencies in calculation and definitions used. Therefore, despite its importance, the lack of consensus on a definition of calf mortality makes it difficult to compare mortality rates between dairy farms or studies. Monitoring factors associated with calf mortality is vital to create preventative strategies. Although common strategies have been set about how to raise dairy calves and manage dairy calves, discrepancies among studies evaluating factors associated with calf mortality still exist. This review summarizes research on the evaluation of calf mortality and associated risk factors, specifically, the lack of reliable data and standardization of the definition of calf mortality. In addition, current strategies to monitor and prevent calf mortality will be presented in this review.
