Grazing Cow Behavior and Lameness [PDF]
Animals, 2020 Development of accelerometer-based lameness (mobility) detection has focused on cow behaviors such as lying and walking. Several studies, usually small, have reported levels of accuracy up to 91%. However, there has been limited independent replication of these results.

Land, 2021 Grazing behavior is a key factor that affects the sustainable development of the grassland social-ecological system. Grazing behavior is not only restricted by policies but also affected by the awareness of the herder of the grassland environment.

Frontiers in Veterinary Science, 2021 In the mountains, autochthonous and robust breeds are often used to valorize biodiverse grasslands. Along with their lower nutrient requirements, compared to specialized dairy breeds, they are expected to be better adapted to complex environments and ...

Timing and Duration of Observation Periods of Foraging Behavior in Natural Grasslands
Frontiers in Veterinary Science, 2020 The goals of this study were to evaluate the length of time grazing which should be monitored over a 24-h period to predict the grazing behavior of beef heifers within a season and determine the patterns of foraging activity over 24 h.

Generic Behavior of Grazing Impact Oscillators [PDF]
Physical Review Letters, 1996 We give experimental evidence for a new bifurcation structure that arises when smooth dynamical systems cross a boundary. Our experiment concerns a driven impacting leaf-spring oscillator with a very precise control of the driving amplitude. The results are in surprisingly good agreement with the predictions of a simple nonlinear mapping that is valid ...

Frontiers in Veterinary Science, 2020 Rearing dairy calves with their mothers could teach them how to graze, optimizing grass use, and improving their welfare and performance. We tested the short-term effects of dam-calf contact experience on grazing and social behavior of weaned calves ...

Some Effects of a Rotational Grazing Treatment on Cattle Grazing Behavior [PDF]
Journal of Range Management, 1989 Research was conducted on the effects of rotational grazing (RG) compared to continuous grazing (CG) on the behavior of cattle grazing on rangelands. Different livestock dent distance walked (km/day), and individual animal space (m2/animrl) in grazing subherds.

Grazing behavior and winter phytoplankton accumulation [PDF]
Biogeosciences, 2021 Abstract. Recent observations have shown that phytoplankton biomass increases in the North Atlantic during winter, even when the mixed layer is deepening and light is limited. Current theories suggest that this is due to a release from grazing pressure.

Relationship between Temperate Grass Sward Characteristics and the Grazing Behavior of Dairy Heifers
Agronomy, 2022 Sward architecture mediates ruminant grazing behavior in temperate grazing lands. Temperate grasses differ in their sward structure, which may influence the grazing behavior of cattle.
