The Effect of Rumination Time on Milk Performance and Methane Emission of Dairy Cows Fed Partial Mixed Ration Based on Maize Silage [PDF]
Animals, 2021 The objective of this study was to determine the effect of the rumination time on milk yield and composition as well as methane emission during lactation in high-yielding dairy cows fed a partial mixed ration based on maize silage without pasture access.

Unraveling the Relationship between Milk Yield and Quality at the Test Day with Rumination Time Recorded by a PLF Technology [PDF]
Animals, 2021 The study aimed to estimate the components of rumination time (RT) variability recorded by a neck collar sensor and the relationship between RT and milk composition. Milk test day (TD) and RT data were collected from 691 cows in three farms.

Association of Rumination Time with Metabolic Imbalance and Milk Quality Traits in Holstein Cattle [PDF]
BiologyRumination time is considered a sensitive behavioral indicator of physiological and metabolic status in dairy cows, yet its relationships with biochemical and milk quality parameters under commercial robotic milking conditions remain insufficiently ...

Effect of Prepartum Magnesium Butyrate Supplementation on Rumination Time, Milk Yield and Composition, and Blood Parameters in Dairy Cows [PDF]
Veterinary Sciences, 2023 Background: Magnesium butyrate (MgB) supplementation of dairy cows during the three-week close-up period was tested for its effects on blood energy analytes, rumination time, inflammation, and lactation performance. Methods: Daily milk yield was recorded

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 ...

Rumination Time Monitoring as a Possible Tool to Improve Diagnostics of Heat and Parturition
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2020 Rumination time is one of possible parameters for observing not only feed management and health status, but also some reproductive characteristics such as heat or periparturient period. The evaluation of rumination time in this study was done on Holstein

Feeding characteristics and rumination time of dairy cows around estrus [PDF]
Journal of Dairy Science, 2015 Against the background of decreasing reproduction efficiency, estrus detection is gaining increased importance. The objective of this study was to evaluate changes of feeding characteristics and rumination time in dairy cows in the days around estrus.

Relationship between daily rumination time and estrus of dairy cows [PDF]
Journal of Dairy Science, 2012 The aim of the study was to investigate whether rumination time (RT) was related to estrus in dairy cattle. On 4 farms, cows were equipped with a microphone-based sensor system that allowed continuous recording (in blocks of 2 h) of RT. The analyzed data set consisted of 265 verified estrus cycles of 224 animals with artificial insemination leading to ...
