“…day in the current study were similar to that reported by Prendiville et al (2010) for lactating Jersey cows at 422, but on average were 163 boli less than that reported by Gregorini et al (2013) for Jersey cows. Rook (2000) outlined how cow anatomy can influence behaviour, with body and muzzle size creating physical limitations, which was also observed in bolus movement during rumination by Prendiville et al (2010).…”

“…In the current study, neither cow genotype nor genetic merit exhibited differences in absolute ruminating behaviour. The lack of association between ruminating time and genetic merit or cow genotype is in line with the findings of Gregorini et al (2013) on lactating dairy cows of diverse genetic merit and Kropp et al (1973) on Hereford and Hereford x Holstein heifers. Values for ruminating time in the current study fall within the range outlined in a review by Kilgour (2012) of 22 studies on grazing beef and dairy (non-milking) cattle encompassing a diversity of production systems, breeds, ages and animal types (heifers, steers, bulls, cows) of 4.7 h to 10.2 h. The values for ruminating time extrapolated in the current study equated to the same proportion of the day (75% of time spent grazing) spent ruminating as outlined by Fraser and Broom (1997).…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  Genotype had no effect on any recorded grazing behaviour variables  High genetic merit cows grazed for longer with more bites but had a lower grass dry matter intake  No significant differences across genetic merit or genotype were observed for rumination measures.  Beef x dairy cows more efficiently convert herbage to milk production than beef

“…The HR cows, on average had higher parity, which is consistent with the observation of greater rumination in older, often more dominant animals, than younger subordinate counterparts (Gregorini et al, 2013). The HR cows also had greater milk production, concentrate intake, and estimated intake, in total.…”

“…These may include differences in digestive capacity (Dado and Allen, 1994) or retention of digesta in the rumen and its rate of passage (Ørskov et al, 1988). The influence of these factors on the rumination of dairy cows at pasture was previously suggested in the study of Gregorini et al (2013), but to our knowledge a paucity of studies have investigated the effect of digestive and physiological drivers on rumination. It is likely that a complex arrangement of both interacting abiotic factors (i.e., distance to pasture or water) and biotic factors (i.e., pasture quality and quantity), which can affect both physiological and behavioral mechanisms, regulate the rumination time of cows at pasture; however, this hypothesis requires further development and investigation.…”

“…Additionally, a paucity of independent studies have compared diurnal rumination patterns (Gregorini et al, 2012(Gregorini et al, , 2013 or CH 4 emissions (Pinares-Patiño et al, 2007) in grazing dairy cows, but no studies to our knowledge have specifically examined the linkages between 24-h rumination and enteric CH 4 production across several days. Understanding the process of ingestion and digestion, including rumination patterning and CH 4 production, may potentiate the opportunity to implement novel rumination-based feeding practices to reduce enteric CH 4 emissions.…”

Proper performance monitoring of cows on pasture-based diets is crucial to inform nutritional recommendations that minimize undesirable effects of high ruminant CH4 emissions into the environment. The prediction of linkages between rumination patterns, methane emissions, and correlated production traits of cows in a pasture-based automatic milking system was tested. A previous 10-d baseline measurement of rumination activity by acoustic methodology of 156 Holstein-Friesian cows was used for frequency analysis of rumination time and identification of 2 treatment groups (n = 37 cows/group) represented by cows with consistently high (HR; 75th rumination percentile = 617.55 ± 81.37 min/d) or low (LR; 25th rumination percentile = 356.65 ± 72.67 min/d) rumination. The HR and LR cows were paired by nearest parity, days in milk, body weight (BW), and previous 10-d milk production, and within pairs randomly assigned to 1 of 2 experimental groups managed on a voluntary milking system with diets consisting of at least 75% pasture, plus concentrates. Animal traits, including rumination time, mass flux of CH4 (QCH4) and carbon dioxide (QCO2), milk production, and estimated dry matter intake according to individual QCO2 fluxes over a 22-d period were analyzed with repeated measure mixed models for a completely randomized design, structural equation modeling, and nonlinear regression. High rumination and methane was seen in older and heavier cows that had greater estimated dry matter intake and milk production. A consistent difference in rumination time and QCH4 across days was detected between HR and LR, even after adjustment for metabolic BW. Estimated dry matter intake had direct positive effects on rumination and QCH4, but no independent direct effect of rumination on QCH4 was detected. The LR cows produced more QCH4/milk, associated with lower milk, BW, concentrate intake, and greater activity at pasture. A typical dilution of maintenance effect on QCH4/milk was detected as a consequence of increasing milk yield and similar significant reduction of QCO2/milk. The results raise challenging questions regarding the rumination patterning of grazing dairy cows and alternatives to reduce ruminant methane emissions in grazing dairy cows.
