Effect of a short-term training on intake of Halocnemum strobilaceum forage by sheep
Contributor(s):: Sadeghi, Mohammad-Hadi, Sari, Mohsen, abadi, Tahereh Mohammad, Rezai, Morteza
Halocnemum strobilaceum (Chenopodiaceae) is a halophyte plant that can produce relatively high consumable biomass during drought and it is important for sustaining grazing animals when other plants are rare. Previous studies indicate that sheep may avoid the plant due to its novelty or neophobia....
Food colour preference of hatchery-reared juveniles of African catfish Clarias gariepinus
Contributor(s):: Kawamura, Gunzo, Bagarinao, Teodora Uy, Asmad, Mohamad Faizal Bin, Lim, Leong-Seng
Food colour preference is a fundamental aspect of food recognition and has practical application in the formulation of artificial diets and the design of visual baits. Food colour affects growth performance and feed efficiency in captive fishes. This study determined the food colour preference of...
Effects of early experience and alternative feeds on medusahead (Taeniatherum caput-medusae ssp. asperum) intake by sheep
Contributor(s):: Montes-Sánchez, Juan J., Villalba, Juan J.
The goals of this study were to test the effects of early experience at grazing medusahead – an invasive unpalatable weed – and the availability of forage alternatives on intake of medusahead later in life by sheep. The study involved two experiments of 10 days each. During Experiment 1, 29...
What do calves choose to eat and how do preferences affect behaviour?
Contributor(s):: Webb, L. E., Engel, B., Berends, H., Reenen, C. G. van, Gerrits, W. J. J., Boer, I. J. M. de, Bokkers, E. A. M.
Calves raised for milk or meat are fed diets that differ from feral-herd calf diets and are based on the nutritional requirements of the 'average calf'. These diets may not meet the dietary preferences of each individual calf. This study explored diet preferences in calves with free dietary...
A two-choice preference assessment with five cotton-top tamarins ( Saguinus oedipus )
Contributor(s):: Fernandez, E. J., Dorey, N. R., Rosales-Ruiz, J.
A study selected 5 cotton-top tamarins (Saguinus oedipus) located at the Frank Buck Zoo in Gainesville, Texas, for a food preference assessment. The study used a paired-choice procedure across 7 different food items for all 5 tamarins. Preferences for the food items across all the tamarins...
Are special feed and being brushed judged as positive by calves?
Contributor(s):: Westerath, H. S., Gygax, L., Hillmann, E.
In studies concerning animal welfare, especially on methods to enhance positive welfare, different stimuli are used to create positive situations or "rewards". A positive judgement by the animals, however, cannot be assumed a priori. The aim of this study was to determine by means of preference...
Effects of chronic intake of starch-, glucose- and fructose-containing diets on eating behaviour in adult minipigs
Contributor(s):: Ochoa, M., Malbert, C. H., Lalles, J. P., Bobillier, E., Val-Laillet, D.
Introduction: The aim of this study was to assess whether chronic intake of isocaloric high-fat diets differing partly in the source of carbohydrates (starch, glucose or fructose) and fed at the same level of intake impacts eating behaviour in the adult Yucatan minipig. Methods: Adult minipigs...
Improved acceptance of Chromonaela odorata by goat kids after weaning is triggered by in utero exposure but not consumption of milk
Contributor(s):: Phan Vu, Hai, Schonewille, J. T., Dam Van, Tien, Everts, H., Hendriks, W. H.
Feeding Chromonaela odorata during pregnancy to goat dams affects acceptance of this feedstuff by their offspring

Comparative behaviour of free-ranging blackbirds ( Turdus merula ) and silvereyes ( Zosterops lateralis ) with hexose sugars in artificial grapes
Contributor(s):: Saxton, V. P., Hickling, G. J., Trought, M. C. T., Creasy, G. L.
In order to detect bird responses to sugar parameters of ripening grapes, artificial grapes containing controlled concentrations of hexose sugars were offered to free-range blackbirds (Turdus merula) and silvereyes (Zosterops lateralis). Time-lapse video was used to observe the two species of...
Diet preference for grass and legumes in free-ranging domestic sheep and cattle: current theory and future application
Contributor(s):: Rutter, S. M.
This paper reviews the current theory and potential practical applications of research on the diet preference for grass and legumes in grazing domestic sheep and cattle. Although much of this work has focussed on grass and clover as a model system, it has wider theoretical implications and...
Dietary preference of dairy heifers grazing ryegrass and white clover, with and without an anti-bloat treatment
Contributor(s):: Rutter, S. M., Orr, R. J., Yarrow, N. H., Champion, R. A.
The effect of an antibloat treatment on the dietary preference of nonpregnant Holstein x Friesian heifers for ryegrass and white clover was studied. Eight groups of two heifers grazed 0.51 ha plots containing adjacent monocultures of grass alongside clover with either 25 or 75% clover (by ground...
Effects of food structure and nutritional quality and animal nutritional state on intake behaviour and food preferences of sheep
Contributor(s):: Villalba, J. J., Provenza, F. D.
There is evidence of the independent effects of plant physical and chemical characteristics on foraging, but little has been done to determine how these traits interact to affect food selection. The effect of the nutritional state of lambs on intake behaviour and preference for feeds with...
Lambs fed protein or energy imbalanced diets forage in locations and on foods that rectify imbalances
Contributor(s):: Scott, L. L., Provenza, F. D.
Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different...
Overcoming food neophobia in domestic ruminants through addition of a familiar flavor and repeated exposure to novel foods
Contributor(s):: Launchbaugh, K. L., Provenza, F. D., Werkmeister, M. J.
Food neophobia, observed as a decreased intake of novel foods, can cause significant livestock production losses. In the transition from rangeland to feedlot, livestock are usually offered novel diets that they sample cautiously, gradually increasing intake. This familiarization period can slow...
Pregnancy in goats does not influence intake of novel or familiar foods with or without toxins
Contributor(s):: Knubel, B. F. R., Panter, K. E., Provenza, F. D.
Some hypothesize that mammals decrease intake of foods that contain toxins during pregnancy to protect the fetus. We conducted a longitudinal study of feeding behavior to determine if pregnancy-related changes in food selection and intake occurred in goats. Goats eat modest amounts of toxic...
The effects of acute simultaneous exposure to ammonia on the detection of buried odourized food by pigs
Contributor(s):: Jones, J. B., Carmichael, N. L., Wathes, C. M., White, R. P., Jones, R. B.
The relative consumption of a range of 15 odourized visible foods by 8 Duroc x Landrace pigs was examined over 15 days in Experiment 1. The most and least preferred food types were identified for later use in olfactory perception tasks in Experiments 2 and 3. Five of these odourized foods are...
Cattle grazing behavior with season-long free-choice access to four forage types
Contributor(s):: Fehmi, J. S., Karn, J. F., Ries, R. E., Hendrickson, J. R., Hanson, J. D.
This experiment investigated how season-long, free-choice grazing affected weekly cattle grazing behaviour and resource use. Our objectives were to determine if known forage preferences change through the season, if feedbacks from previous grazing intensity affect current use, and if resources...
Differences in food preferences between individuals and populations of domestic cats Felis silvestris catus
Contributor(s):: Bradshaw, J. W. S., Healey, L. M., Thorne, C. J., Macdonald, D. W., Arden-Clark, C.
The food preferences of 64 cats, of which 28 were domestic pets and 36 were free-ranging animals on three farms, were tested using 5 food types; a sixth type was also tested on the farm cats. Information was also gathered on the background diet of the house cats (individually) and of each farm...
Feed preference by Baladi goats
Contributor(s):: Abdel-Moneim, A. Y., Abd-Alla, M. S.
Eight adult (24-48 months) and 8 juvenile (6-12 months) Baladi does were maintained on a diet of Egyptian clover (Trifolium alexandrinum) or darawa (Zea mays) supplemented with concentrates. After an overnight starve, goats were given the choice of 2 green forages (clover, darawa and sorghum...
