Ambient mass spectrometry for rapid authentication of milk from Alpine or lowland forage

open access: yesScientific Reports, 2022
AbstractMetabolomics approaches, such as direct analysis in real time-high resolution mass spectrometry (DART-HRMS), allow characterising many polar and non-polar compounds useful as authentication biomarkers of dairy chains. By using both a partial least squares discriminant analysis (PLS-DA) and a linear discriminant analysis (LDA), this study aimed ...

Soil bulk density and biomass partitioning of Brachiaria decumbens in a silvopastoral system Densidade do solo e partição de biomassa de Brachiaria decumbens em um sistema silvopastoril

open access: yesScientia Agricola, 2010
Shade in silvopastoral systems improves the thermal comfort of animals, but it may also affect the pasture productivity and can contribute to soil compaction in the shaded areas due to the increase in the number of animals looking for comfort. The effect

Rising Plate Meter Calibrations for Forage Mass of Wheat and Rye [PDF]

open access: yesAgricultural & Environmental Letters, 2019
Core Ideas The rising plate meter was useful in predicting forage mass. A quadratic functional form is favored for predicting forage mass using the rising plate meter. Relationships differed by species, season, and tillage Estimating forage availability is important in optimizing livestock stocking rates.

Forage Mass Estimation in Silvopastoral and Full Sun Systems: Evaluation through Proximal Remote Sensing Applied to the SAFER Model

open access: yesRemote Sensing, 2023
The operational slowness in the execution of direct methods for estimating forage mass, an important variable for defining the animal stocking rate, gave rise to the need for methods with faster responses and greater territorial coverage. In this context,

Torrefaction behaviour of various biomass types: kinetics of solid mass loss and release of volatiles [PDF]

open access: yes, 2011
Feedstock variability is a crucial issue for industrialization of biomass conversion processes. Indeed, this variability may imply large differences of chemical reaction rates and products yields and therefore differences of reactors design.

What Is the Maximum Nitrogen Dose for the Fertilization of BRS Tamani?

open access: yesNitrogen
This study aimed to determine the optimal nitrogen (N) fertilization rate per regrowth cycle for Megathyrsus maximus cv. BRS Tamani by evaluating its effects on forage production, nutrient uptake, bromatological composition, and in vitro degradation ...

How Are Warm-Season Pastures’ Nutritive Value and Fermentation Characteristics Affected by Open Pasture, Silvopasture, and Sward Herbage Maturity?

open access: yesAgronomy, 2023
This study aimed to evaluate the forage mass and nutritional value (NV) of Guinea Massai grass (Megathyrsus maximus × Megathyrsus infestum) in an open pasture (OP) or the silvopastoral system (SPS) at different stages of development (SDs).

Uranium and Associated Heavy Metals in Ovis aries in a Mining Impacted Area in Northwestern New Mexico. [PDF]

open access: yes, 2017
The objective of this study was to determine uranium (U) and other heavy metal (HM) concentrations (As, Cd, Pb, Mo, and Se) in tissue samples collected from sheep (Ovis aries), the primary meat staple on the Navajo reservation in northwestern New Mexico.

Methodologies in the evaluation of forage mass in tree legumes

open access: yesRevista Brasileira de Ciências Agrárias - Brazilian Journal of Agricultural Sciences, 2018
To choose the method of forage mass estimation (FM), consider the plant species, required accuracy and available technology. In this sense, the objective was to evaluate the methods of determination of direct FM and comparative visual per­formance with five and 10 patterns, in the trees Gliricidia (Gliricidia sepium Jacq.) and Sabia (Mimosa ...
