Using Changes in Eating and Rumination Time to Indicate the Onset of Parturition or Changes in the Health Status of Dairy Cows

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2021
Monitoring the time of rumination and eating of dairy cows, by new technologies, is increasingly used in commercial herds. Evaluation of parameters obtained from Vitalimeter 5P, was performed in 656 dairy cows Czech Fleckvieh and Holstein cattle ...

Automatic identification and analysis of multi-object cattle rumination based on computer vision

Journal of Animal Science and Technology, 2023
Rumination in cattle is closely related to their health, which makes the automatic monitoring of rumination an important part of smart pasture operations. However, manual monitoring of cattle rumination is laborious and wearable sensors are often harmful

Associations of Grazing and Rumination Behaviours with Performance Parameters in Spring-Calving Dairy Cows in a Pasture-Based Grazing System

Animals, 2023
This study investigated the relationship of the length of time spent grazing and ruminating with the performance parameters of spring-calved grazing dairy cows (n = 162) over the lactation period for three lactation seasons (n = 54 per season).

Real-time monitoring of ruminal microbiota reveals their roles in dairy goats during subacute ruminal acidosis [PDF]

npj Biofilms and Microbiomes, 2021
AbstractRuminal microbiota changes frequently with high grain diets and the occurrence of subacute ruminal acidosis (SARA). A grain-induced goat model of SARA, with durations of a significant decrease in the rumen pH value to less than 5.6 and an increase in the rumen lipopolysaccharides concentration, is constructed for real-time monitoring of ...

Suitability of rumination time during the first week after calving for detecting metabolic status and lactation performance in simmental dairy cows: a cluster-analytic approach

Italian Journal of Animal Science, 2021
An unsupervised machine learning approach (ML) of rumination time (RT) data was used to evaluate metabolic and lactation performance in a cohort of Simmental dairy cows (29) around parturition.

Ruminations on Cosmology and Time

Notices of the American Mathematical Society, 2021
“I have been riveted for decades by the breathless bulletins from cosmologists describing the latest twist to their model of space and time at the largest possible scale. This article is partly to share the beauty of this theory with my colleagues but also to express how thoroughly relativity shakes up our deep psychological conviction of the reality ...

Usually, I Don't Ruminate, Only From Time To Time: Disentangling The Associations Between Trait And State Measures Of Rumination And Affect At Multiple Timescales

Cognition and Emotion, 2023
Recent experience sampling research on affective functioning has emphasized the importance of short-term dynamics, yet rarely evaluates whether momentary measures are better explained by stable individual differences or by within-individual fluctuations.
