“…Rumination time is affected by quantity and quality of the feed ration, the parity and its phase (Beauchemin and Rode, 1997;Yang and Beauchemin, 2006;Adin et al, 2009). Bulky feed with higher fiber content requires higher amount of chewing movements (Suzuki et al, 2014). This can be put into context with length of individual feed particles, when longer particles require longer rumination time (Nørgaard et al, 2011).…”

Rumination time is one of possible parameters for observing not only feed management and health status, but also some reproductive characteristics such as heat or periparturient period. The evaluation of rumination time in this study was done on Holstein dairy cows in period around heat (n = 297) and around parturition (n = 322) during one year. SAS 9.3 was used for statistic evaluation. Factors such as heat or periparturient period but also a parity or month within the year have significant impact on rumination time. The decrease of rumination time in the average of 19% (more than 100 minutes) was observed in heat time against days before heat. Similarly, decrease of rumination time more than 110 minutes was observed on the day of parturition in comparison with days before that day. However, the return to normal rumination time values was gradual within 3 day after calving. The results indicated that in healthy cows the rumination time can be a good indicator not only of approaching periparturient but also of incoming heat.

“…It can be defined as a process characterized by regurgitation, mastication, and re-swallowing of ingesta (Beauchemin, 1991). The number of chews per bolus is associated with the fiber content of the feed, but in general rumination activity can be influenced by several environmental factors, such as the nature and amount of feed (Metz, 1975;Suzuki et al, 2014) or milking schedules and patterns of lighting (Beauchemin, 1991). Adult cows ruminate approximately 8 h per day in 4 to 24 periods, each lasting 10 to 60 min (Gáspárdy et al, 2014).…”

The objective of this study was to evaluate the ear-tag-based accelerometer system Smartbow (Smartbow GmbH, Weibern, Austria) for detecting rumination time, chewing cycles, and rumination bouts in indoor-housed dairy cows. For this, the parameters were determined by analyses of video recordings as reference and compared with the results of the accelerometer system. Additionally, we tested the intra- and inter-observer reliability as well as the agreement of direct cow observations and video recordings. Ten Simmental dairy cows in early lactation were equipped with 10-Hz accelerometer ear tags and kept in a pen separated from herd mates. A total mixed ration was fed twice a day via a roughage intake control system. During the study, cows' rumination and other activities were directly observed for 20 h by 2 trained observers. Additionally, cows were video recorded for 19 d, 24 h a day. After exclusion of unsuitable videos, 2,490 h of cow individual 1-h video sequences were eligible for further analyses. Out of this, one hundred 1-h video sequences were randomly selected and visually and manually classified by a trained observer using professional video analyses software. Based on these analyses, half of the data was used for development (based on data of 50-h video analyses) and testing (based on data of additional 50-h video analyses) of the Smartbow algorithms, respectively. Inter- and intra-observer reliability as well as the comparison of direct against video observations revealed in high agreements for rumination time and chewing cycles with Pearson correlation coefficients >0.99. The rumination time, chewing cycles, as well as rumination bouts detected by Smartbow were highly associated (r > 0.99) with the analyses of video recordings. Algorithm testing revealed in an underestimation of the average ± standard deviation rumination time per 1-h period by the Smartbow system of 17.0 ± 35.3 s (i.e., -1.2%), compared with visual observations. The average number ± standard deviation of chewing cycles and rumination bouts was overestimated by Smartbow by 59.8 ± 79.6 (i.e., 3.7%) and by 0.5 ± 0.9 (i.e., 1.6%), respectively, compared with the video analyses. In summary, the agreement between the Smartbow system with video analyses was excellent. From a practical and clinical point of view, the detected differences were negligible. However, further research is necessary to test the system under various field conditions and to evaluate the benefit of incorporating rumination data into herd management decisions.

“…In agreement with previous study, Zebeli et al (2012b) mentioned that sufficiency of dietary fiber can be determined by using PeNDF which is a representation of chemical fiber content and particle size information. Particle size and chemical content of dietary fiber have effects on dry matter intake (DMI), feeding behavior and ruminal mat formation (Zebeli et al 2007;Suzuki et al 2014). A study using different size of forage length particle and high and low forage feeding suggested that forage proportion and forage particle length contribute significantly to saliva production that prevent the cases of acidosis in dairy cattle (Yang & Beauchemin 2007).…”

Feeding high concentrate diet, characterized with high starch and low fiber is applied to increase energy intake for an optimal production performance in ruminants. However, the prevalence of digestive disorder namely ruminal acidosis has been reported as drawback of this feeding strategy. This encourages farmers and nutritionist to supply adequate fiber in the diet to meet minimum dietary fiber requirement. However, feeding high forage diet is reported to give adverse effect on production performance, thus economic loss for farmers. Therefore, some sorts of artificial fiber utilizations have been introduced to reduce the risk of nutritional diseases as well as improving ruminant productivity. The utilization of rumen mechanical stimulator aims to maintain a healthy rumen function in ruminants fed with high concentrate diet. Objective of this article is to review recent development of rumen mechanical stimulators utilization, a pseudo fiber to substitute forage physical function in the rumen of ruminants. This review highlights the use of rumen mechanical stimulators in dairy cattle, beef cattle and sheep with particular attention in rumination time and rumen parameters. In conclusion, rumen mechanical stimulator is attributable to minimize metabolic problem associated with high concentrate feeding by providing mechanical stimulation on the rumen wall.
