Tall fescue sward structure affects the grazing process of sheep. [PDF]

Sci Rep, 2020
AbstractThe study of factors influencing animal intake can provide a better understanding of the dynamics of the pasture ecosystem and serve as a basis for managing livestock in a more efficient way. We measured different sward surface heights of tall fescue in the process of short-term intake rate of sheep.

Mowing and lowering the marandu palisadegrass sward height at late winter improve the sward structure

Bioscience Journal, 2020
The structure of the sward is important because it influences the responses of plants and animals in grazing conditions. The objective with this work was to evaluate the structural characteristics of the Marandu palisade grass pasture (Brachiaria ...

Sward structure and nutritive value of Alexandergrass fertilized with nitrogen [PDF]

Anais da Academia Brasileira de Ciências, 2016
This experiment evaluated forage production, sward structure, stocking rate, weight gain per area and nutritive value of forage as grazed by beef heifers on Alexandergrass (Urochloa plantaginea (Link) Hitch) pasture fertilized with nitrogen (N): 0; 100 ...

Characterization of grazing behaviour microstructure using point-of-view cameras

PLoS ONE, 2022
Grazing patterns, intake structure, and diet selection are dynamic responses to animals’ feeding environment. This study uses video sequences from animal-borne cameras to capture time- and scale-dependent grazing behaviour variables related to sward ...

Low-Intensity, High-Frequency Grazing Strategy Increases Herbage Production and Beef Cattle Performance on Sorghum Pastures

Animals, 2021
We assessed the effects of high-intensity and low-frequency (HILF) vs. low-intensity and high-frequency (LIHF) grazing on herbage production and performance of beef cattle grazing sorghum pastures.

Changes in sward structure, plant morphology and growth of perennial ryegrass–white clover swards over winter

Irish Journal of Agricultural and Food Research, 2021
White clover (Trifolium repens L.) is at a disadvantage to perennial ryegrass (Lolium perenne L.; PRG) due to its limited cold tolerance and low growth rates at colder temperatures, which can affect subsequent spring herbage dry matter (DM) availability.

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.

The Usefulness of Mixtures with Festulolium braunii for the Regeneration of Grassland under Progressive Climate Change

Agriculture, 2021
The climate warming and changes in weather patterns in Europe are negatively affecting the structure of grassland swards. The disappearance of valuable forage grasses can be observed. Therefore, in order to keep grassland productivity high, high-yielding

Sward structural resistance and biting effort in grazing ruminants [PDF]

Animal Research, 2003
Grazing ruminants face complex decisions in searching for and harvesting adequate forage to meet their requirements in the face of heterogeneity in the abundance, nutritive value and distribution of resources. Some of the major decisions which affect the bite mass and therefore, forage intake adjustments in bite depth, bite area and exerted bite force,

Tillering and forage accumulation in Marandu grass under different grazing intensities

Revista Ceres, 2011
Studies of plant responses to defoliation are important to develop pasture management strategies. The objective of this study was to evaluate the population density of basal, aerial and reproductive tillers, tiller appearance and mortality rates, forage ...
