Screw-pressed fractions from green forages as animal feed: Chemical composition and mass balances

Animal Feed Science and Technology, 2020
Abstract In colder humid areas, green forages are recognised as high protein yielding crops and have the potential to be a locally grown sustainable protein source. However, without processing, the protein cannot be properly utilised by monogastrics.

Parallel Plate Mass Flow Sensor for Forage Crops and Sugar Beet

2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008
Measurements described in this paper were realized in order to find out whether there is some relationship between mass flow of plant material passing through a parallel plate capacitive sensor and its output signal. This possibility of mass flow determination could be useful for the aim of forage crops or sugar beet yield maps creation.

Foraging decisions in a capital breeder: trade-offs between mass gain and lactation

Oecologia, 2009
The high energetic costs of lactation can lead to fundamental trade-offs in life-history traits, particularly in young females that reproduce before completing body growth. We assessed whether lactating female mountain goats (Oreamnos americanus) used behavioural tactics at fine spatio-temporal scales to increase energy intake to compensate for the ...

Flight speed and body mass of nectar-feeding bats (Glossophaginae) during foraging

Journal of Experimental Biology, 1999
ABSTRACT Aerodynamic theory predicts that minimum power (Vmp) and maximum range (Vmr) flight speeds increase when the body mass of an individual animal increases. To evaluate whether foraging bats regulate their flight speed within a fixed speed category relative to Vmp or Vmr, I investigated how the natural daily changes in body mass ...

Forage Nutritive Value and Herbage Mass Relationship of Four Warm‐Season Grasses

Agronomy Journal, 2016
To provide animals with high quality forage, practical methods are needed to estimate nutritive value to optimize harvest timing. The objective of this study was to develop such models to estimate warm‐season forage nutritive value in the southeastern United States.

Forage Mass and Water Use Response to Irrigation Time in North China

Agronomy Journal, 2010
Siberian wildrye grass (Elymus sibiricus L.) is the primary forage species in alpine cold areas of North China. Scheduled irrigation is an important way to increase the forage mass because of water shortage and the inconsistency between rainy season and the most intense water use period.

The regulatory mechanism in mass foraging and the recruitment of soldiers inPheidole

Insectes Sociaux, 1970
Observations of the recruitment behaviour ofPheidole within the nest reveal the existence of a complex behavioural mechanism which operates in the recruitment of nestmates, including the soldiers, to mass foraging. Highly excited recruiters, arriving at the nest, perform, in addition to trail-laying, a motor recruitement display comprising running ...
