Relationships Between Milk Fat and Rumination Time Recorded by Commercial Rumination Sensing Systems [PDF]

Journal of Dairy Science, 2020
Low rumination in the dairy cow is often assumed to result in reduction of saliva flow, rumen buffering, and milk fat, which is a major contributor to milk value in many pricing systems. Rumination time (RT) of individual cows can be measured with commercial rumination sensing systems, but our understanding of how daily RT (minutes per day) is related ...
