Early identification of sick cattle increases treatment success and decreases mortality. Continuous automated records of behavior can be used to identify sick cattle early in the disease process. The objective was to evaluate accuracy of an ear-attached accelerometer (SensOor) that quantified ear movements and estimated feeding and rumination time through a proprietary algorithm. Accelerometers were attached to the ear tag of 18 steers with an initial mean BW of 326 ± 46 kg. The manufacturer's… 

Technical Note: Evaluation of an ear-attached movement sensor to record rumination, eating, and activity behaviors in 1-month-old calves

Sixteen male Holstein calves were fitted with ear-attached motion sensors to evaluate the sensor’s ability to record rumination, eating, and activity behavior compared with scan sampling by trained observers.

Validation of an ear tag-based accelerometer system for detecting grazing behavior of dairy cows.

There is potential for the ear tag to be used on pasture-based dairy farms to support management decision-making and a grazing algorithm for an ear tag-based accelerometer system using data from a noseband sensor is developed.

Identification of the Rumination in Cattle Using Support Vector Machines with Motion-Sensitive Bolus Sensors

It is demonstrated for the first time that by processing the reticuloruminal motion, it is possible to recover rumination periods.

Technical note: Validation of a behavior-monitoring collar's precision and accuracy to measure rumination, feeding, and resting time of lactating dairy cows.

This study validates the high precision of rumination, resting, and feeding behaviors measured by a behavior-monitoring collar in lactating dairy cows.

Evaluation of the RumiWatchSystem for measuring grazing behaviour of cows

Utilizing an electronic feeder to measure individual mineral intake, feeding behavior, and growth performance of cow–calf pairs grazing native range1

Crossbred Angus cow–calf pairs at the Central Grasslands Research Extension Center were used to evaluate an electronic feeder to monitor individual mineral intake and feeding behavior and their relationship with growth performance and liver mineral concentrations, and the divergence in mineral intake observed with the feeder was corroborated by concentrations of minerals in the liver.

A Pilot Study Using Accelerometers to Characterise the Licking Behaviour of Penned Cattle at a Mineral Block Supplement

Overall, the tri-axial accelerometer was capable of identifying licking behaviour of beef cattle in a controlled environment and further developing a practical method of estimating mineral block supplement intake by individual grazing cattle.

Automated Monitoring of Panting for Feedlot Cattle: Sensor System Accuracy and Individual Variability

An accelerometer-based ear tag-based sensor was validated for the monitoring of panting in cattle and the individual variability in panting duration for heat stress events was determined, comparing with existing thermal indices.



Technical note: Evaluation of an ear-attached movement sensor to record cow feeding behavior and activity.

Evidence is provided that the present ear sensor technology can be used to monitor ruminating and resting behavior of freestall-housed dairy cattle and that this technology shows promise for monitoring eating behavior, whereas more work is needed to determine its suitability to monitor activity of dairy cattle.

Validation of a system for monitoring feeding behavior in beef cattle.

Evaluating the use of an electronic radio-frequency-identification-based system to measure feeding behavior traits in beef cattle fed a high-grain diet indicated the GrowSafe system 4000E was able to predict BV and meal event data when the 100-s MPS was used to analyze the feeding behavior data.

Technical note: validation of rumination collars for beef cattle.

Physical and dietary differences between dairy and beef cattle may have resulted in the inaccuracy of the Hi-Tag system when used in beef cattle fed typical backgrounding and finishing diets.

Validating the accuracy of activity and rumination monitor data from dairy cows housed in a pasture-based automatic milking system.

Data indicate that ACT and RUM do reflect cow walking and rumination, respectively, but not with a high degree of accuracy, and lying cannot be distinguished from standing.

Technical note: Validation of a system for monitoring rumination in dairy cows.

The objective was to validate the data generated by this electronic rumination monitoring system, which indicated that the electronic system was an accurate tool for monitoring this behavior in dairy cows.

An Automatic System for Quantification of Eating and Ruminating Activities of Dairy Cattle Housed in Stalls

Eating was overestimated by both automatic systems because the transducer was unable to distinguish between jaw movements caused by eating and grooming activities, and ruminating was estimated accurately by monitoring jaw movements.

Evaluation of a system for monitoring rumination in heifers and calves.

The results indicate that the Hi-Tag system is an accurate tool for monitoring rumination behavior in Holstein Friesian heifers from the age of 9 mo, and that suckling from a teat interfered with recording from this system.

Evaluation of data loggers, sampling intervals, and editing techniques for measuring the lying behavior of dairy cattle.

The accuracy of the Onset Pendant G data logger for measuring lying behavior in dairy cattle was tested and it accurately measured all aspects of lying behavior when the sampling interval was ≤30 s and when short readings of lying and standing were filtered from the data set.

Technical note: validation of a system for monitoring individual feeding and drinking behavior and intake in group-housed cattle.

This electronic system is a useful tool for monitoring intakes and feeding and drinking behavior of loose-housed cows and showed a high specificity (100%) and sensitivity (100 and 99.76% for the feed and water bins, respectively) for cow identification.

Relationship between feeding behavior and performance of feedlot steers fed barley-based diets.

Steers with more variable eating patterns exhibited greater ADG and tended to have greater G:F, a finding that is contrary to industry perception.
