| Abstract | The HR neck collar (SCR, Israel) is a rumination monitoring system combined with a unique motion sensor. The basic principle of using sounds picked up by a microphone that is in tight contact to the cow’s neck to measures rumination time (RT), has been developed by A. BarShalom (Vocal Tag, Israel). This system, after technological upgrade, is integrated in commercial activity tags (Hi-Tag) and is named HR-Tag (or QWES-HR Tag if they are part of Lely’s Astronaut A3 milking robot system). The rumination data is downloaded to and stored in the herd computer after each milking or any time a cow passes under a tag reader, and is available as individual or group reports, produced by the herd management software (DataFlow, SCR, Israel). Rumination is recognized by analyzing the chewing sounds, and excluding the sounds related to eating. Data is stored in "2 hours cells", in 2 minutes resolution. The RT parameter may be applicable in 2 areas: I – nutrition management, and II health and cow's welfare sensor. It is well accepted in the scientific literature that on the average a dairy cow ruminates about 35-40% of the day. Where ration supplies adequate physical properties, and still significant decrease in rumination has occurred, this may suggest that stress factors, such as health, management, climatic condition (heat stress) or animal welfare disturbance are involved. The objective of this study was to track changes in RT during some physiological, health, nutrition, and management and climatic events, on a commercial dairy farm. |
