“…Near-continuous observation of preparturient mares is extremely labour-intensive, and time requirements would be markedly reduced with automated monitoring systems. In cattle, automated monitoring and alert systems are used for oestrous detection (Chanvallon et al, 2014;Pennington, Albright, & Callahan, 1986;Roelofs, van Eerdenburg, Soede, & Kemp, 2005) and health management (Borchers, Chang, Tsai, Wadsworth, & Bewley, 2016;Müller & Schrader, 2003) and are also increasingly advocated for monitoring of cows before calving (Krieger et al, 2017;Marchesi et al, 2013;Ouellet et al, 2016). Monitoring devices in cattle are often made for long-term recordings and are fixed permanently on the animal whereas for birth alert, pedometers (Nishimura et al, 2017;Titler et al, 2015) or intravaginal sensors (Palombi et al, 2013) are used.…”

Observation of preparturient mares is labour-intensive and time requirements would be reduced with automated monitoring systems. Recently, small-size accelerometers have become available. We followed the hypothesis that increased restlessness in mares shortly before the expulsive stage of labour can be detected with such accelerometers. Accelerometers were attached medioventrally to the halter of eight late pregnant mares. To evaluate an influence of accelerometer position, in one mare two additional accelerometers were attached close to the mandibular and atlanto-occipital joints. Accelerometers were programmed to send 600 signals/min (10 Hz). Signals were recorded continuously and, for evaluation, four intervals of 30-min duration on day 4 before foaling and the last 2 hr before rupture of the allantochorion at foaling were selected. Signal detection was influenced by position of the accelerometer on the mares' halter. The highest signal detection rate was reached with the accelerometer in the lateral and dorsal position but differences of accelerations measured by the system differed neither between sensor positions nor between time intervals 4 days before foaling. Differences of accelerations increased from 120 min before foaling until birth of the foal (p < 0.001) and this increase was most pronounced during the last 30-20 min before birth of the foal (p < 0.001). Technical improvements and a foaling specific algorithm are required to improve the accuracy to predict foaling. Even if this preliminary study included only a small number of mares, results demonstrate that accelerometers could be an important component of birth alert systems in horses in the future.

“…The number of animals that had to be culled was three times higher in the group with the longer retention time than in the group with the shorter retention time (33.0 % vs. 10.1 %, P≤0.05). In contrast to [5], who tested the birth monitoring device C6, the iVET ® system was not well tolerated by all heifers and caused irritation and discomfort to the heifer which may lead to neuro-hormonal alterations of the birth process. This could be one reason for the high percentage of dystocia and injuries.…”

“…Many researchers claimed that sensitive accelerometers can detect subtle differences which appear in the behavior of cows in early disease states. The most frequent methods used wileyonlinelibrary.com/jsfa 51,52 to detect lame cows include various types of visual interpretation of the locomotion of individual cows, i.e. visual locomotion scoring systems.…”

Comparison of different applications of automatic herd control systems on dairy farms – a review

Recent years have seen the rapid development of different devices which can be helpful in the daily work of livestock farmers. The growing size of livestock herds has led farmers to lose individual contact with their animals, while behavioral studies show that breeders can effectively and precisely monitor a herd of up to 100 cows. This was the main motivation for this study, which aims to identify and test various electronic devices which provide useful herd management data, including estrus detection, individual activity and body temperature measurement, monitoring rumen pH levels, milk quality and content as well as milk temperature and somatic cell count measurements. Some devices can detect the metabolic status of animals with a reasonable level of precision. Contemporary animal farms are offered a large number of systems for monitoring the behavior of the animals in the herd and helping to identify those that are intended for insemination or are too active or excessively apathetic. Monitoring devices support herd management and help to reduce costs through the early detection of animal diseases and nutritional problems. This review aims to compile and summarize the information currently available on the use of automatic herd control systems on dairy farms, as well as to discuss the interpretation of the results, providing a useful diagnostic tool in nutritional evaluations of dairy herds. © 2018 Society of Chemical Industry.
