Daily Forage Intake by Cattle on Natural Grassland: Response to Forage Allowance and Sward Structure [PDF]

, 2016
We investigated the hypothesis that not only forage allowance but also sward structure affects daily forage intake by beef heifers on natural grasslands of the Pampa Biome (southern Brazil).

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 ...

Effect of grazing intensity and dung on herbage and soil nutrients

Plant, Soil and Environment, 2019
Dung deposited by grazing animals is a key driver affecting sward structure and nutrient cycling in pastures. We tested herbage and soil properties in three types of tall sward-height patches (> 10 cm): (i) patches with dung under intensive grazing ...

Selective grazing by sheep as affected by the structure and composition of a Lolium perenne and Trifolium repens sward [PDF]

, 1978
Perennial ryegrass/white clover swards were manipulated to give a range of clover contents and structures. The influence of sward composition and structure on diet selection was examined using oesoph-ageally fistulated sheep grazing four plots with ...

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.

Lapwing and Redshank Nesting Sites on Coastal Marshes: Does Sward Structure Matter? [PDF]

, 2023
Grazing is central to the debate on wildlife conservation. Agricultural grasslands are the main breeding areas for many waders and grazing is very important in grassland use by these species.

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Característica produtiva e estrutural de pastos mistos de aveia e azevém manejados em quatro alturas sob lotação contínua Structural and productive characteristic of oat and ryegrass mixed pastures managed in four intensities with variable stocking rate

Revista Brasileira de Zootecnia, 2010
Monitoraram-se variáveis relacionadas à produção e à estrutura de pastos de aveia-preta (Avena strigosa, Schreb) e azevém (Lolium multiflorum, Lam) manejados em quatro alturas (10, 20, 30 e 40 cm), em pastejo contínuo com lotação variável (put and take).

Rational Design of Organic Chromophores for Simultaneously Trig‐gering Redox Imbalance and Tracking Organelles in Biological Sys‐tems Under Near‐Infrared Light Irradiation

Advanced Healthcare Materials, EarlyView.
TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

Initial height and nitrogen fertilization on deferred signalgrass

Bioscience Journal, 2015
Thus study was conducted with the objective of evaluating production and forage characteristics of Signalgrass (Brachiaria decumbens cv. Basilisk) deferred at different initial heights and nitrogen doses. Three initial sward heights (low - 10 cm, medium
