Influence of agricultural management, sward structure and food resources on grassland field use by birds in lowland England. [PDF]

, 2005
Agricultural management of grassland in lowland Britain has changed fundamentally in the last 50 years, resulting in spatial and structural uniformity within the pastoral landscape.

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 ...

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).

The Effect of Sward Structure and N Fertilization on the Grass-legume Silage Quality [PDF]

Tarım Bilimleri Dergisi, 2016
The effect of sward structure of the mixtures and nitrogen fertilization on grass-legume silage quality was investigated over two years. The study included Lucerne (Medicago sativa) in monoculture and in mixtures with cocksfoot (Dactylis glomerata), tall fescue (Festuca arundinacea) and sainfoin (Onobrychis sativa).

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.

Ingestive Behavior of Young Lambs on Contrasting Tropical Grass Sward Heights

Frontiers in Veterinary Science, 2020
The efficiency of grazing ruminant production systems is directly associated to the animals' ingestive behavior, and to structural characteristics of the pastures.

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 ...
