Structural characteristics of marandu palisadegrass swards subjected to continuous stocking and contrasting rhythms of growth Características estruturais de pastos de capim-marandu submetidos à lotação contínua e ritmos de crescimento contrastantes

Scientia Agricola, 2010
The concept of sward target has been used recently to characterise grazing management practices, but its efficiency to monitor and control sward structure questioned since it corresponds to a single sward structural feature, usually sward surface height.

The use of frequency estimates in studying sward structure

Grass and Forage Science, 1992
AbstractEstimates of the frequency of absence of rooted perennial ryegrass tiller bases from concentric sampling quadrats of different sizes are recommended for characterizing the open space structure of perennial ryegrass swards. It is proposed that these estimates are useful for evaluating the persistence of grass species and cultivars in swards ...

How does the sward condition in late winter influence the Marandu palisade grass (Urochloa brizantha cv. Marandu) structure during spring and summer?

Tropical Grasslands-Forrajes Tropicales, 2020
Height and mowing of a sward in late winter can change its structure during the subsequent spring and summer seasons, which influences plant growth and animal performance.

Can Low-Cost Unmanned Aerial Systems Describe the Forage Quality Heterogeneity? Insight from a Timothy Pasture Case Study in Southern Belgium

Remote Sensing, 2020
Applied to grazing management, unmanned aerial systems (UASs) allow for the monitoring of vegetation at the level of each individual on the pasture while covering a significant area (>10 ha per flight).

Mapping and Monitoring of Biomass and Grazing in Pasture with an Unmanned Aerial System

Remote Sensing, 2019
The tools available to farmers to manage grazed pastures and adjust forage demand to grass growth are generally rather static. Unmanned aerial systems (UASs) are interesting versatile tools that can provide relevant 3D information, such as sward height ...

A comparison of two rotational stocking strategies on the foraging behaviour and herbage intake by grazing sheep

Animal, 2020
An understanding of the processes involved in grazing behaviour is a prerequisite for the design of efficient grassland management systems. The purpose of managing the grazing process is to identify sward structures that can maximize animal forage daily ...

Animal performance and sward characteristics of Mombaça guineagrass pastures subjected to two grazing frequencies

Tropical Grasslands-Forrajes Tropicales, 2020
The aim of this work was to compare grazing management practices of Mombaça guineagrass (Megathyrsus maximus syn. Panicum maximum cv. Mombaça) based on the sward incident light interception (LI) concept.

Sheep production during the rainy season in marandu palisadegrass swards previously utilized under deferred grazing

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
The objective of this study was to evaluate the effects of Brachiaria brizantha cv. Marandu syn. Urochloa brizantha cv. Marandu (Marandu palisadegrass) in late winter on pasture structure, apparent selectivity, and sheep production during spring and ...
