Journal of Agricultural Studies, 2022 This study evaluated the relationships between supplement intake behavior, beef cattle performance, and grazing behavior on dormant northern mixed-grass rangelands. In each of two years, a commercial herd of bred cows grazed a rangeland pasture from November to January. All cattle were managed as one contemporary group.

Lameness and lying behavior in grazing dairy cows [PDF]
Journal of Dairy Science, 2019 Lameness is a serious welfare issue for dairy cows. To date, the majority of studies have focused on its effect on health and behavior at the herd level. The objectives of this study were to identify (1) between-cow and (2) within-cow changes in lying behavior associated with consistent and changing lameness status in grazing dairy cows.

Infection by Parorchis acanthus (Trematoda) decreases grazing by the keystone gastropod, Littoraria irrorata [PDF]
PeerJ, 2018 Parasites are well-known to alter the behavior of their hosts, but there is still a paucity of knowledge about how parasites modify the behavior of many ecologically influential host species.

Animals, 2019 Different grazing management systems are practiced on upland dairy farms during summer, depending on topography, local traditions, and infrastructure. The present experiment compared two distinct management systems with respect to feeding behavior and ...

Animals, 2022 Species-rich pastures naturally contain potentially toxic plants such as common ragwort (Senecio jacobaea L.), whose pyrrolizidine alkaloids (PA) impose a risk, mainly for cattle and horses.

Frequent Allocation of Rotationally Grazed Dairy Cows Changes Grazing Behavior and Improves Productivity [PDF]
Journal of Dairy Science, 2008 Twenty Holstein cows were blocked in 2 groups according to milk yield to evaluate the effect of frequency of allocation to new grazing plots on pasture intake, grazing behavior, rumen characteristics, and milk yield. The 2 treatments, daily allocation to 0.125-ha plots (1D) or allocation every 4 d to 0.5-ha plots (4D) of Lolium perenne L., were tested ...

Grazing Systems, Pasture Size, and Cattle Grazing Behavior, Distribution and Gains [PDF]
Journal of Range Management, 1993 Reduced pasture size and distance to water may be responsible for the alleged benefits of intensive time-controlled rotation grazing systems. We compared cattle gains, activity, distance traveled, and forage utilization on a time-controlled rotation system with eight 24-ha pastures, on two 24-ha pastures grazed continuously (season-long), and on a 207 ...

Cattle Grazing and Behavior on a Forested Range [PDF]
Journal of Range Management, 1982 Environmental and topographic parameters on a mountainous forested range were analyzed to establish causes of cattle behavioral responses. Distinct home range groups of cattle were identified through examination of quality and patterns of forage use, cattle distribution, herd social structure, and cattle activities.
