Breeding limits foraging time: evidence of interrupted foraging response from body mass variation in a tropical environment [PDF]

Journal of Avian Biology, 2017
Birds should store body reserves if starvation risk is anticipated; this is known as an ‘interrupted foraging response’. If foraging remains unrestricted, however, body mass should remain low to limit the predation risk that gaining and carrying body reserves entails.

Dynamics of sward condition and botanical composition in mixed pastures of marandugrass, forage peanut and tropical kudzu

Revista Brasileira de Zootecnia, 2012
This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides),

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

Remote 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,

Methodologies in the evaluation of forage mass in tree legumes

Revista 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 ...

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

Agronomy, 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).

Forage intake processes by goats on a massai grass pasture with different sward heights

Semina: Ciências Agrárias, 2016
The objective of this study was to evaluate the forage-intake process of goats feeding on Massai grass pastures with different heights (40, 50, 60, and 70 cm). The experimental design was completely randomized, with treatments corresponding to four sward

Breeding Efficiency for Salt Tolerance in Alfalfa

Life, 2023
Alfalfa (Medicago sativa L.), one of the most extensively grown forage crops, is sensitive to saline soils. We measured the breeding efficiency for increased salt tolerance in alfalfa by comparing lines selected from BC79S, CS, and SII populations with ...

To eat and not be eaten: diurnal mass gain and foraging strategies in wintering great tits [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2018
Adaptive theory predicts that the fundamental trade-off between starvation and predation risk shapes diurnal patterns in foraging activity and mass gain in wintering passerine birds. Foragers mitigating both types of risk should exhibit a bimodal distribution (increased foraging and mass gain early and late in the day), whereas both foraging and mass ...

Vegetation composition and forage mass in grassland with a double structure under two winter grazing regimes

Ciência Rural, 2018
: Remnant areas of Pampas grassland have a distinct double structure. Efficiency of livestock farming on these grasslands depends on practices that are synchronized with natural variation.
