Improving calving management to further enhance reproductive performance in dairy cattle.

The aim of this study was to develop a system for the monitoring of calving to both reduce perinatal mortality and improve dairy cow fertility by preventing the majority of post-partum reproductive pathologies. Eighty dairy cows were assigned to the protocol of calving monitoring using GSM (Global System for Mobile Communications) technology. The application of GSM technology and the proper management of calving facilities comprise reliable approaches for calving assistance and improvements in reproductive efficiency and neonatal viability. Based on the results of this study, we advocate the use of GSM technology on large farms for intensive milk production.
