The welfare of ferrets (Mustela putorius furo T): a review on the housing and management of pet ferrets
Contributor(s):: Vinke, C. M., Schoemaker, N. J.
Ear and tail postures as indicators of emotional valence in sheep. (Special Issue: Animal suffering and welfare.)
Contributor(s):: Reefmann, N., Kaszas, F. B., Wechsler, B., Gygax, L.
To date, most studies on animal emotions have focused on the assessment of negative emotional states, and there is a lack of approaches to characterising positive emotional states. The aim of this investigation was to measure differences in ear and tail postures in sheep exposed to situations...
Equine ingestion of haylage harvested at different plant maturity stages
Contributor(s):: Muller, C. 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...
Group sizes and resting locations of free range pigs when grazing in a natural environment
Contributor(s):: Rodriguez-Estevez, V., Sanchez-Rodriguez, M., Gomez-Castro, A. G., Edwards, S. A.
A herd of 86 Iberian pigs aged 13+or-0.5 months and with an average live weight of 110+or-1.3 kg at the start of the study was followed to monitor their social organisation (spontaneous group size: GS) and resting preferences when free ranging on natural pastures in a dehesa of evergreen oaks...
Survey of breeders' management of horses in Europe, North America and Australia: comparison of factors associated with the development of abnormal behaviour
Contributor(s):: Parker, M., Goodwin, D., Redhead, E. S.
An online survey of domestic horse breeders in the USA, UK, Australia, Canada and mainland Europe was carried out in order to examine management risk factors associated with the development of abnormal behaviour patterns. One hundred and forty breeders responded, and epidemiological results...
Behavioural patterns of heifers under intensive and extensive continuous grazing on species-rich pasture in the Czech Republic
Contributor(s):: Hejcmanova, P., Stejskalova, M., Pavlu, V., Hejcman, M.
This study examines the effects of season and of two grazing intensities, namely extensive grazing (EG) and intensive grazing (IG), on the grazing behaviour of heifers on species-rich upland pasture in the Czech Republic. Ten or eight (IG), and six or four (EG) heifers were continuously stocked...
Breed and maternal effects on the intake of tannin-rich browse by juvenile domestic goats ( Capra hircus )
Contributor(s):: Glasser, T. A., Ungar, E. D., Landau, S. Y., Perevolotsky, A., Muklada, H., Walker, J. W.
Goat breeds differ in their consumption of tannin-rich browse, but the relative contributions of genetics and learning to these differences is unclear. The objective of this study was to differentiate between the effects of breed (nature) and rearing environment (nurture) on consumption of a...
Instantaneous intake rate in horses of different body sizes: influence of sward biomass and fibrousness
Contributor(s):: Fleurance, G., Fritz, H., Duncan, P., Gordon, I. J., Edouard, N., Vial, C.
The functional response, that is the relationship between the food intake rate of a forager and the availability of food items, has been subject to numerous investigations in ruminants. In horses however, the functional response has been poorly studied despite of the importance of grazed forage...
Landscape nutritional patterns and cattle distribution in rangeland pastures
Contributor(s):: Ganskopp, D. C., Bohnert, D. W.
On rangelands, uneven or unmanaged livestock distribution can adversely affect plant community composition, riparian function, or displace wildlife. These issues have historic precedents and are still a challenge for those managing rangelands. A thorough understanding of the mechanisms governing...
Statistical and probabilistic estimators of forage conditions from grazing behaviour of Merino sheep in a semi-arid environment
Contributor(s):: Dudzinski, M. L., Schuh, H. J., Wilcox, D. G., Gardiner, H. G., Morrissey, J. G.
The flock structure of Merino ewes and rams was recorded from the air in 22 surveys over 3 yr in a large semi-arid area of W. Australia. Forage production and body wt. data were collected over the same period. A dispersion index, DI (with zero value when all the sheep were in 1 group and with...
Effect of processing and feeding strategy of the spineless cactus ( Opuntia ficus-indica Mill.) for lactating cows: ingestive behavior
Contributor(s):: Vilela, M. da S., Ferreira, M. de A., Azevedo, M. de, Modesto, E. C., Farias, I., Guimaraes, A. V., Bispo, S. V.
The aim of this study was to assess the effects of feeding strategy and processing of the spineless cactus on the ingestive behavior of lactating Holstein cows. Eight cows with a mean live weight of 453+or-75.8 kg, production of 14 kg of milk per day and 20 weeks of lactation at the beginning of...
Social companionship versus food: the effect of the presence of familiar and unfamiliar conspecifics on the distance steers travel
Contributor(s):: Patison, K. P., Swain, D. L., Bishop-Hurley, G. J., Pattison, P., Robins, G.
The social motivation of a grazing individual to remain in close proximity to its peer is dependent on many factors, particularly the level of familiarity with its peers and the desire to forage further away. This study examined the trade-off individual cattle have to make between a food reward...
Effects of fly disturbance on the behaviour of a population of reintroduced Przewalski horses ( Equus ferus przewalskii ) in Mongolia
Contributor(s):: King, S. R. B., Gurnell, J.
Flies constitute a cost to animals by feeding from them, passing on disease or by preventing them feeding effectively. These costs could be more severe to animals suffering from some kind of stress such as reintroduction as part of a conservation programme. This study focused on the effects of...
On the rewarding nature of appetitive feeding behaviour in pigs ( Sus scrofa ): do domesticated pigs contrafreeload?
Contributor(s):: Jonge, F. H. de, Tilly, S. L., Baars, A. M., Spruijt, B. M.
Contrafreeloading is the phenomenon that animals prefer to "work" for food even though "free" food is available nearby. In this study, we investigated whether pigs express contrafreeloading in a test situation where the searching, finding and consuming of food items resembles a natural foraging...
Foraging mechanics and their outcomes for cattle grazing reproductive tropical swards
Contributor(s):: Benvenutti, M. A., Gordon, I. J., Poppi, D. P., Crowther, R., Spinks, W.
For grazing animals an important determinant of animal performance is the rate of nutrient intake (RNI) which depends on diet quality and instantaneous intake rate (IIR). In turn, diet quality and IIR are the outcome of the interaction between the morphology and behaviour of the animal and the...
RICHPIG: a semantic model to assess enrichment materials for pigs
Contributor(s):: Bracke, M. B. M.
A computer-based model was constructed to assess enrichment materials (EMats) for intensively-farmed weaned, growing and fattening pigs on a scale from 0 to 10. This model, called RICHPIG, was constructed in order to support the further implementation of EC Directive 2001/93/EC, which states that...
Stakeholders' assessment of welfare indicators for sheep and cattle exported by sea from Australia
Contributor(s):: Pines, M. K., Petherick, J. C., Gaughan, J. B., Phillips, C. J. C.
An adaptive conjoint analysis was used to evaluate stakeholders' opinion of welfare indicators for ship-transported sheep and cattle, both onboard and in pre-export depots. In consultations with two nominees of each identified stakeholder group (government officials, animal welfare...
