“…Monitoring a total of 103 multiparous cows, RT was affected in both prepartum and postpartum during autumn calving season, with an average of 5% to 6% decline (on a daily basis) in cows that experienced metritis, but this did not take place in spring calving season. In the same paper, this was clearly attributed to the THI level between 2 and 10 days after calving (Held-Montaldo et al, 2021). According to these results, it is important to consider RT pattern as a marker of different coexisting factors affecting it; therefore, great prudence must be used in the RT data interpretation.…”

The rumen and its activity, rumination, are the characterizing traits of the suborder Ruminantia, and it is accompanied by related feeding habits and consequent animal behavior. Several extrinsic (not related to the animal itself) factors affect rumination behavior; most are reflected in rumination timing (considering overall daily duration as well as circadian differences in rumination patterns): age, environmental factors, and diet. For these reasons, great efforts have been sustained at the research level for monitoring rumination patterns. Currently, some research outcomes are applied at the farm level; others are still at the experimental level. All of these efforts are finalized mainly for the use of rumination pattern recording as an effective prediction tool for the early detection of health and welfare problems, both in a single head and at the herd level. Moreover, knowledge of the effects of extrinsic factors on rumination physiology represents a great challenge for improving the efficiency of ruminant livestock management, from the diet to the housing system, from parasites to heat stress. The present review deals mainly with the worldwide raised ruminant species.

“…To our knowledge there are no studies assessing prepartum DMI and transition disease risk in grazing herds, but the use of rumination monitors in grazing cattle has shown promise as a surrogate measure to assess feeding behavior in this system. In one very recent study, grazing cows with metritis had lower daily rumination times in the prepartum period compared with cows that did not developed metritis, but this association was only present during the autumn period and when temperature-humidity index was above 68 (Held-Montaldo et al, 2021).…”

Transition period (±3 wk around calving) diseases are prevalent in dairy systems. In this review we describe the physiological and behavioral changes experienced by cows during the transition period and during the dry period leading up to this. Our narrative review examines risk factors associated with these diseases in zero-grazing and grazing systems. The available research indicates that cows in these 2 systems experience similar incidences of transition diseases, and that low or high BCS and lameness are key manageable risks associated with both systems. Other cow-and herdlevel risk factors identified in this review are parity, breed, and seasonal variability in disease incidence. Some risks appear to arise earlier in the dry period, outside what is normally considered the transition period; we recommend that future studies of transition period diseases should consider the entire dry period. We also encourage new work on measuring the effect of intervention strategies during late lactation on transition period diseases.
