Influence of sward height on diet selection by horses

open access: yesApplied Animal Behaviour Science, 2005
Abstract Foraging herbivores are often faced with spatial and temporal heterogeneity within the vegetation they have available to graze and therefore have to make decisions where and when to graze. The study reported in this paper investigated the influence of sward height on diet selection by horses grazing perennial rye-grass swards.

The effect of plane of winter nutrition and sward height on the performance of steers grazing grass/white clover swards

open access: yesGrass and Forage Science, 1996
AbstractAn experiment was carried out over 2 years to examine the interactions between two planes of winter nutrition and summer gracing at 5.5 and 7.5 cm compressed sward height on the performance of Limousin X Friesian steers grazing grass/white clover swards.

Piata palisadegrass deferred in the fall: effects of initial height and nitrogen in the sward structure [PDF]

open access: yesRevista Brasileira de Zootecnia, 2012
The objective of this study was to evaluate the mass of the forage and of the morphological components, and the sward structure in Piata palisadegrass (Brachiaria brizantha cv. Piata) deferred in function of different initial heights and nitrogen levels.

Effect of sward height and sheep breed on sward composition during summer grazing period [PDF]

open access: yesProceedings of the British Society of Animal Science, 1995
The sward height could determine the intake of the herbivores and, at the same time, to affect to sward composition (Morris et al., 1994). If the foraging strategies is different among species could be also different among breeds of sheep (Milne, 1991).

Effect of Sward Height on Rumen Degradation in Merino Grazing Sheep [PDF]

open access: yesProceedings of the British Society of Animal Production (1972), 1993
It is now well established that the height of the sward grazed by sheep has a large effect on their performance (Hodgson, Mackie and Parker, 1986). However, there is a scarce of information about the rumen fermentation in sheep grazing at different sward heights.

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

open access: yesRemote 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).

Canopy characteristics, animal behavior and forage intake by goats grazing on Tanzania-grass pasture with different heights - doi: 10.4025/actascianimsci.v34i4.14544

open access: yesActa Scientiarum: Animal Sciences, 2012
This study evaluated the influence of Tanzania-grass sward height (30, 50, 70 and 90 cm) on the morphological characteristics of the canopy, grazing behavior and forage intake by adult Anglo Nubian female goats.

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

open access: yesRemote 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 ...

Measuring sward height and dry matter yield of pastures using multispectral imagery from UAV and a random forest algorithm

open access: yes, 2020
In Switzerland, more than 80% of agricultural land consists of semi-natural grassland with a very diverse species composition and a heterogeneous growth pattern.
