Preference and motivation for different diet forms and their effect on motivation for a foraging enrichment in captive Orange-winged Amazon parrots (Amazona amazonica)
Contributor(s):: Rozek, Jessica C., Millam, James R.
Motivation tests were conducted to assess preference strength for diet form and a cage enrichment device by Orange-winged Amazon parrots (Amazona amazonica) held in individual cages, N=10. Each cage was equipped with two trough-type feeders, one of which had a hinged lid that required lifting to...
Introduction of gum Arabic and guar to the diet of captive black-tufted ear marmosets
Contributor(s):: Pupe, Rafael, Tavares, Maria Clotilde Henriques, Barros, Marilia
Gum plays a significant role in the feeding ecology of wild callitrichids and thus is also supplemented to several primate species in captivity. However, little is known about the feeding habits of black tufted-ear marmosets (including gummivory), in both wild and captive populations. Therefore,...
Equine ingestion of haylage harvested at different plant maturity stages
Contributor(s):: Müller, Cecilia E.
The influence of plant maturity at harvest of haylage on equine ingestion times and ingestive behaviour was studied. Haylage was harvested at three different occasions: June, July and August, from the primary growth of the same grass-dominated sward. Twelve adult horses of European warmblood type...
Foraging Performance, Prosociality, and Kin Presence Do Not Predict Lifetime Reproductive Success in Batek Hunter-Gatherers

Foraging performance, prosociality, and kin presence do not predict lifetime reproductive success in batek hunter-gatherers
The interplay between exposure and preference for unpalatable foods by lambs
Contributor(s):: Villalba, Juan, Spackman, Casey, Lobón, Sandra
Herbivores satiate on single foods ingested too frequently or in excess. We hypothesized that exposure to the same unpalatable food too frequently or in excess causes satiety, which in turn would reduce subsequent use and preference for this food when alternatives become available. In each of...
Monitoring the effects of feeding in groups: Behavioural trials in farmed elk in winter
Contributor(s):: Moreira, Adam, McLaren, Brian
We studied the effect of managing group size in domesticated elk in the context of social foraging theory, and toward recommendations for livestock well-being and efficient use of common pastures. We compared foraging in adult female elk presented with feeding trays of alfalfa pellets mixed with...
Decision-making of goats when exposed to choice feeding: Triggered by taste or smell?
Contributor(s):: Scherer, R., Gerlach, K., Südekum, K. H.
Animals recognise known forages. However, it is unclear whether recognition is mainly based on sensory characteristics linked to postingestive feedback or whether the latter is activated each time before a choice is made. Moreover, knowledge is scarce regarding the duration of the memory process...
Some like it varied: Individual differences in preference for feed variety in dairy heifers
Contributor(s):: Meagher, Rebecca K., Weary, Daniel M., von Keyserlingk, Marina A. G.
Motivation to explore is believed to be widespread among animals, but exploratory behaviour varies within populations. Offering variety in feed is one simple way of allowing intensively housed dairy cattle to express exploratory foraging behaviour. Individuals’ exploration of different feed...
Behavioral patterns of (co-)grazing cattle and sheep on swards differing in plant diversity
Contributor(s):: Cuchillo Hilario, Mario, Wrage-Mönnig, Nicole, Isselstein, Johannes
Both botanical composition and the presence of additional grazer species may modify the grazing efficiency and ingestive behavior of ruminants. However, at present, potential effects of interactions between sward diversity and presence of multiple animal species on the grazing behavior of cattle...
Feeding, foraging, and feather pecking behaviours in precision-fed and skip-a-day-fed broiler breeder pullets
Contributor(s):: Girard, Ms Teryn E., Zuidhof, Martin J., Bench, Clover J.
Broiler breeder chickens are feed-restricted to control growth and maximize chick production. Feed restriction creates welfare concerns as conventional skip-a-day feeding can increase activity levels and oral stereotypies during the rearing period. A precision feeding system has been developed to...
Mother-offspring relationship in Morada Nova sheep bred in a tropical semiarid environment: A perspective on maternal investment and parental conflict
Contributor(s):: Fonsêca, Vinícius F. C., Saraiva, Edilson P., Arruda, Maria F., Pereira, Walter E., Pimenta Filho, Edgard C., Santos, Severino G. C. G., Amorim, Mikael L. C. M., Silva, Josinaldo A.
In 2011 and 2012, we investigated the mother-offspring relationship in 60 Morada Nova ewe-lamb pairs from lambing (August) until 40 d after lambing. In years 1 and 2, there were 28 and 32 multiparous ewes, 13 and 20 single male lambs, and 15 and 12 twin male lambs, respectively. The behavior of...
Nutritional state and secondary compounds influence trembling aspen (Populus tremuloides) intake by lambs
Contributor(s):: Heroy, Kristen Y., St. Clair, Samuel B., Burritt, Elizabeth A., Durham, Susan L., Villalba, Juan J.
The foraging ecology of mammalian herbivores is determined by plant secondary compounds (PSC) that defend plants against herbivory, by nutrients that are required for maintenance, growth, and reproduction, and by the interaction between these variables. In this study, we explored the influence of...
Effects of guest feeding programs on captive giraffe behavior
Contributor(s):: Orban, D. A., Siegford, J. M., Snider, R. J.
Zoological institutions develop human-animal interaction opportunities for visitors to advance missions of conservation, education, and recreation; however, the animal welfare implications largely have yet to be evaluated. This behavioral study was the first to quantify impacts of guest feeding...
"Who's been a good dog?" - Owner perceptions and motivations for treat giving
Contributor(s):: White, G. A., Ward, L., Pink, C., Craigon, J., Millar, K. M.
Complex relationships commonly exist between owners and their companion animals, particularly around feeding behaviour with an owner's affection or love for their animal most pronounced through the provision of food. It is notable that the pet food market is experiencing strong year-on-year...
Local knowledge held by farmers in Eastern Tyrol (Austria) about the use of plants to maintain and improve animal health and welfare
Contributor(s):: Vogl, C. R., Vogl-Lukasser, B., Walkenhorst, M.
Background: The sustainable management of animal health and welfare is of increasing importance to consumers and a key topic in the organic farming movement. Few systematic studies have been undertaken investigating farmers' local knowledge related to this issue. Ethnoveterinary medicine (EVM) is...

Giant otters (Pteronura brasiliensis) and humans in the lower Yasuní Basin, Ecuador : spacio-temporal activity patterns and their relevance for conservation
Contributor(s):: Paola M. Carrera-Ubidia
Giant otters (Pteronura brasiliensis) and humans in the Lower Yasuní Basin (Ecuador) have similar food and space requirements: they consume comparable arrays of fish species, and they use similar aquatic and terrestrial habitats. Resource partitioning could facilitate coexistence by...
Effects of feeding management and group composition on agonistic behaviour of group-housed horses
Contributor(s):: Burla, Joan-Bryce, Ostertag, Anic, Patt, Antonia, Bachmann, Iris, Hillmann, Edna
Under natural conditions, horses spend 12-18 h of a day with synchronous grazing, but for stabled horses, the amount of forage and thus duration of feed intake usually are restricted. In group-housed horses, therefore, feeding times are often situations with increased levels of agonistic...
