The influence of eating and rumination time on solids content in milk and milk yield performance of cows

Czech Journal of Animal Science, 2023
The aim of this study was to evaluate the effect of rumination time, eating time and season on milk yield and on milk component content in the context of milk recording. The experiment was carried out with two breeds - Czech Fleckvieh cattle and Holstein

Investigating rumination and eating time as proxies for identifying dairy cows with low methane-emitting potential

JDS Communications
Identifying cows with low CH4-emitting potential can greatly contribute to CH4 abatement in dairy herds. However, this process has been cumbersome and labor-intensive.

A comparative analysis of rumen pH, milk production characteristics, and blood metabolites of Holstein cattle fed different forage levels for the establishment of objective indicators of the animal welfare certification standard [PDF]

Animal Bioscience, 2022
Objective This study was conducted to obtain an objective index that can be quantified and used for establishing an animal welfare certification standard in Korea. For this purpose rumen pH, ruminating time, milk yield, milk quality, and blood components

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
Abstract Ruminal 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 ...

Rumination-focused cognitive behaviour therapy vs. cognitive behaviour therapy for depression: study protocol for a randomised controlled superiority trial. [PDF]

, 2015
BACKGROUND: Cognitive behavioural therapy is an effective treatment for depression. However, one third of the patients do not respond satisfactorily, and relapse rates of around 30 % within the first post-treatment year were reported in a recent meta ...

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.
