Forage mass and nutritional value of elephant grass intercropped with forage legumes1 [PDF]
Revista Ceres, 2021 Forage-legume systems are a sustainable and competitive alternative for improving pasture yield and quality because of the symbiotic nitrogen fixation capacity and high nutritional value of legumes.

Forage mass, botanical composition and stocking density of bermudagrass overseeded with forage legumes [PDF]
Revista Ceres, 2017 Pastures of the genus Cynodon are being cultivated alone in conventional production with high rates of nitrogen fertilizer. Information and research about its use on mixed-pasture system is scarce.

Foraging dive frequency predicts body mass gain in the Adélie penguin [PDF]
Scientific Reports, 2021 AbstractQuantifying food intake in wild animals is crucial to many ecological and evolutionary questions, yet it can be very challenging, especially in the marine environment. Because foraging behavior can be inferred from dive recordings in many marine creatures, we hypothesized that specific behavioral dive variables can indicate food intake. To test

Forage mass and the nutritive value of pastures mixed with forage peanut and red clover [PDF]
Revista Brasileira de Zootecnia, 2012 The objective of this research was to estimate three pasture-based systems mixed with elephantgrass + spontaneous growth species, annual ryegrass, for pasture-based system 1; elephantgrass + spontaneous growth species + forage peanut, for pasture-based system 2; and elephantgrass + spontaneous growth species + annual ryegrass + red clover, for pasture ...

Forage and splanchnic tissue mass in growing lambs: Effects of dietary forage levels and source on splanchnic tissue mass in growing lambs [PDF]
British Journal of Nutrition, 1994 Forty-two crossbred lambs (33·4 kg initial body weight; twenty-four wethers and eighteen ewes) were used in a 42 d experiment with a 2 × 3 factorial treatment arrangement to determine effects of forage level and source on splanchnic tissue mass. Diets were 250 and 750 g/kg of chopped lucerne (Medicago sativa) (A), ryegrass (Lolium multiflorum)–wheat ...

<b>Forage mass and nutritive value of bermuda grass mixed to forage peanut or common vetch [PDF]
Acta Scientiarum. Animal Sciences, 2016 Three pasture-based systems (PS) with bermuda grass (BG) + forage peanut + 75 kg of N ha-1; BG + common vetch + 75 kg of N ha-1 and BG + 150 kg of N ha-1 were evaluated. Lactating Holstein cows were used for evaluation and the experimental design was completely randomized.

Optimal distributions of central-place foragers: honey bee foraging in a mass flowering crop
Behavioral Ecology, 2022 AbstractThe ideal-free distribution and central-place foraging are important ecological models that can explain the distribution of foraging organisms in their environment. However, this model ignores distance-based foraging costs from a central place (hive, nest), whereas central-place foraging ignores competition.

Effects of maternal age and mass on foraging behaviour and foraging success in the northern elephant seal [PDF]
Functional Ecology, 2013 SummaryAnimals that show indeterminate growth and put relatively constant proportions of stored body reserves towards annual reproductive effort are confronted with a problem of meeting ever‐increasing energetic demands in unpredictable environments.We examined how intrinsic traits, mass and age, as well as extrinsic environmental features impact ...

Mass Fluctuations Suggest Different Functions of Bimodal Foraging Trips in a Central-place Forager [PDF]
Behavioral Ecology, 2012 The function of a foraging trip (self-feeding or provisioning) and the spatial distribution of food resources play an essential role in foraging decisions of central-place foragers. Theory predicts that if foraging patches optimal for self-feeding and provisioning are spatially separated, a bimodal foraging strategy should often be favored.

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).
