“…Ruminal motility in the cattle was measured by a strain gauge force transducers [4]. The size of the force transducer was 18 × 35 mm, and the force transducer contained the strain gauge (Foil Strain Gauge; NEC San-ei Instruments, Ltd., Tokyo, Japan).…”

We evaluated the relationship between ruminal motility measured by a force transducer and acceleration measured by bolus sensor, and we assessed the detection of ruminal motility in cattle by a bolus-type wireless sensor. The bolus sensor can be orally administered to cattle and was placed in the reticulum for continuous measurements. The probe was almost horizontal to the longitudinal axis. The bolus sensor's basic y-axis acceleration movement appeared to have a very distinct vertical pattern, occurring roughly 1−1.5 times/min with a duration of approximately 8 sec, displaying at around 500 mG. A significant positive correlation was observed between the ruminal contraction revealed by the force transducer and the acceleration shown by the bolus sensor (P<0.01). The contraction of the dorsal sac of the rumen and the acceleration signals in the reticulum occurred at practically the same time. The frequency and amplitude of ruminal contraction demonstrated by the bolus sensor and the force transducer in feeding were significantly higher than those at rest (P<0.01). The bolus sensor could also detect ruminal atony in the cattle after the administration of xylazine. A bolus-type wireless sensor may thus be useful for the measurement of ruminal motility in cattle and for detecting rumen dysfunction (e.g., ruminal atony).

“…Measuring methods recently used in ruminants, such as force transducer method [ 11 , 12 ], restrained electromyography [ 4 ], or ultrasonographic examination [ 7 , 8 ] required an animal restriction. On the other hand, an application of accelerometers in bolus wireless sensors [ 9 , 10 ] does not allow long-term registration. Therefore, since the myoelectric activity of smooth muscle of the reticulo-rumen reflects its contractile activity [ 1 , 2 , 3 ], telemetry EMG recording appears to be currently the only method that allows measures of long-term gastrointestinal motility on the unrestrained animal.…”

“…The forestomach motility in ruminants can be assessed physiologically using direct and indirect methods. Indirect methods, such as ultrasonography [ 7 , 8 ] and bolus wireless sensors with an accelerometer [ 9 , 10 ], have some limitations. Bolus sensors have numerous artifacts whereas ultrasonography approaches do not provide easy access to all components.…”

“…Kania et al [ 17 ], Sarna et al [ 18 ], and Plaza et al [ 4 ] used cable signal transmission, which caused long-term immobilization of the animals and limited the duration of registration from 6 [ 5 , 18 ] to 12 h [ 4 ]. In contrast, considering all available methods, ultrasonography allowed us to exam the few minutes of forestomach activity [ 7 , 8 ], whereas, the telemetry bolus-type sensor enable a few hours of observation [ 9 , 10 , 12 ]. Therefore, this study presented EMG registration using long-term telemetry method of signal transmission.…”

The reticulum and rumen are considered a single functional unit (the reticulo-rumen) with regards to myoelectrical and contractile activities. The specialized contractions of the reticulo-rumen provide constant mixing of partially digested material (cycle A), its flow into the omasum during eructation (cycle B), and regurgitation-rumination (cycle C). This study aimed to investigate the feasibility of electromyography (EMG) registered by a long-term telemetry method for assessment of the basic reticulo-rumen myoelectrical activity in sheep, to develop the effective recognition of the reticulo-rumen cycles at rest with no food stimulation, and to investigate the relationship between cycles A, B, and C in such basic conditions. The experiment was carried out on nine ewes. Myoelectric activity of the rumen, reticulum, and abomasum was recorded by the combination of three silver bipolar electrodes and a 3-channel transmitter implant. The myoelectrical activity registered successfully in the reticulum and rumen was determined as three characteristic patterns of cycles A, B, and C. The percentage of each type of cycle changed at different intervals from equally cycles A (43–50%) and B (50–56%), occurring when cycle C was not observed to the domination of cycle C (57–73%) with a decrease of cycles A (6–14%) and B (20–28%). The long-term EMG telemetry registration is feasible in the assessment of the reticulo-rumen myoelectrical activity in sheep.

Quantifying digestive and fermentative processes within the rumen environment has been the subject of decades of research; however, our existing research methodologies preclude time-sensitive and spatially explicit investigation of this system. To better understand the temporal and spatial dynamics of the rumen environment, real-time and in situ monitoring of various chemical and physical parameters in the rumen through implantable microsensor technologies is a practical solution. Moreover, such sensors could contribute to the next generation of precision livestock farming, provided sufficient wireless data networking and computing systems are incorporated. In this review, various microsensor technologies applicable to real-time metabolic monitoring for ruminants are introduced, including the detection of parameters for rumen metabolism, such as pH, temperature, histamine concentrations, and volatile fatty acid concentrations. The working mechanisms and requirements of the sensors are summarized with respect to the selected target parameters. Lastly, future challenges and perspectives of this research field are discussed.
