The Developing Forager

2018
Studies of regional and chronological variation in skeletal markers of physical activity in past hunter-gatherer populations typically focus on adults, however, patterns of bone strength develop predominantly during childhood and adolescence. Ethnographic studies suggest that differences in environment and subsistence strategy would have brought about ...

Effects of forage species or concentrate finishing on animal performance, carcass and meat quality.

Journal of Animal Science, 2013
Angus-cross steers (n = 128; initial BW = 270 ± 3.8 kg) were used in a 3-yr study to assess effects of forage species grazed before slaughter versus concentrate finishing on carcass and meat quality. At the completion of the stockering phase, steers were

The foraging behavior of honeybees on hairy vetch foraging methods and learning to forage

Insectes Sociaux, 1956
The honeybee can reach the nectar from the mouth of the hairy vetch blossom by tripping it, or she can insert her tongue between the petals at the base of the corolla tube and reach the nectar. These non-trippers are called base workers. The foraging method is learned and becomes fixed through success at foraging from a very few blossoms in one manner ...

FORAGE: a model of forage intake in beef cattle

Ecological Modelling, 1992
Abstract A deterministic simulation model (FORAGE) has been developed as an interface between the plant and animal components of a general rangeland ecosystem model (SPUR). The model predicts forage intake and diet selection of grazing beef cattle by simulating the mechanistic components of grazing behavior.

Determination of extractable and bound condensed tannin concentrations in forage plants, protein concentrate meals and cereal grains

, 1992
A procedure was developed for extraction of ‘free’ condensed tannins (CT) using a mixture of acetone/water/diethyl ether (4.7:2.0:3.3), followed by extraction of protein-bound and fibre-bound CT using boiling sodium dodecyl sulphate containing 2 ...

Treatment of Forage with Sulphur Dioxide in a Forage Harvester

Transactions of the ASAE, 1985
ABSTRACT TWO chemicals (NH3 and S02) benefit the preservation of forage but are difficult to apply because of their physical characteristics. The physiological effects of either chemical on the farm worker complicate the task. A commercially available applicator for NH3 was tried for applying S02 to forage as it was conveyed by the cross auger of a ...

Honeyeater foraging: A test of optimal foraging theory

Animal Behaviour, 1981
Abstract Honeyeaters (Meliphagidae) were observed foraging for nectar from Lambertia formosa inflorescences, each of which has seven flowers. The frequency distribution of numbers of flowers probed per visit to an inflorescence was found to be bimodal, with one peak at two and the other at seven.
