Leaf age structure and canopy photosynthesis in rotationally and continuously grazed swards

Grass and Forage Science, 1988
AbstractThe leafage structure of ryegrass canopies and its role in canopy photosynthesis were compared under continuous and rotational grazing by sheep. Under continuous grazing, an increase in the intensity of grazing increased the proportion (by leaf area) of young leaves in the sward. A mechanistic mathematical model was used to demonstrate how this

Sward structure changes within a perennial ryegrass swara: leaf appearance and death

Grass and Forage Science, 1983
AbstractThe appearance of successive leaves on labelled tillers of S24 perennial ryegrass, and their subsequent death, were monitored for 1 year on cut plots on which four levels of N fertilizer were applied.A new leaf appeared about once every 15 d from the end of April until the beginning of September, and about once every 52 d from the end of ...

Habitat use by indigenous grazing ungulates in relation to sward structure and veld condition

Journal of the Grassland Society of Southern Africa, 1990
The objective of this study was to examine the relationships between the habitat requirements of different wild ungulate species, sward structure and veld condition. Veld condition score was correlated with sward height: habitats with high condition scores were dominated by tall grass species, whereas habitats with low scores were dominated by ...

Short-term foraging dynamics of cattle grazing swards with different canopy structures.

Journal of animal science, 2010
The objective of the present experiment was to describe the sward canopy structures of 3 different wheat (Triticum aestivum L.) pastures and relate them to short-term herbage intake rate and foraging dynamics by steers. Pastures were sampled for leaf and stem fractions at the bottom, middle, and top canopy strata.

Grazing as a tool to create sward structures suitable to breeding birds.

2004
French wet grasslands support important populations of Lapwings and other waders. Grazing management is a key issue since these birds are very sensitive to sward structure (grass height heterogeneity). During three years, repeated measurements of sward height were conducted in a coastal marsh in order to assess the impact of different grazing regimes ...
