Impact of flooring type on the sham dustbathing behaviour of caged laying hens
Contributor(s):: Moroki, Yuko
Feed particles are preferred for foraging and they are also a stimulus for sham dustbathing. Most sham dustbathing bouts start with bill raking in the feed by caged hens. As hens often exhibit a floor scratching behaviour, an element of both sham dustbathing and foraging, by moving their legs...
Effect of large litter size and within-litter differences in piglet weight on the use of milk replacer in litters from hyper-prolific sows under two housing conditions
Contributor(s):: Kobek-Kjeldager, Cecilie, Moustsen, Vivi A., Theil, Peter K., Pedersen, Lene J.
Due to genetic selection for large litters in pig production, piglets are often supernumerary to the teats on the sow. Providing milk replacer as a second feed source is increasingly being used to rear large litters. This results in increased competition at the udder when all piglets remain at...
What do calves choose to eat and how do preferences affect behaviour?
Contributor(s):: Webb, Laura E., Engel, Bas, Berends, Harma, van Reenen, Cornelis G., Gerrits, Walter J. J., de Boer, Imke J. M., Bokkers, Eddie 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...
Effects of genetic selection for residual feed intake on behavioral reactivity of castrated male pigs to novel stimuli tests
Contributor(s):: Colpoys, Jessica D., Abell, Caitlyn E., Young, Jennifer M., Keating, Aileen F., Gabler, Nicholas K., Millman, Suzanne T., Siegford, Janice M., Johnson, Anna K.
Increasing feed efficiency in swine is important for increasing sustainable food production and profitability for producers; therefore, this is often selected for at breeding. Residual feed intake (RFI) can be used for the genetic selection of pigs for feed efficiency. In our selection project,...
Effects of different systems of feeding supplements on time budgets of cows grazing restricted pasture allowances
Contributor(s):: Hetti Arachchige, Anoma D., Fisher, Andrew D., Auldist, Martin J., Wales, William J., Jongman, Ellen C.
Farm systems that use a feed-pad for delivering mixed-rations to dairy cows are becoming more common in countries with primarily pasture-based dairy systems, such as Australia. However, feeding a ration on a feed-pad may alter cows’ key daily behaviours such as grazing, ruminating and resting,...
Are special feed and being brushed judged as positive by calves?
Contributor(s):: Westerath, H. Schulze, 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...
Investigating the influence of predictable and unpredictable feed delivery schedules upon the behaviour and welfare of Atlantic salmon parr (Salmo salar) using social network analysis and fin damage
Contributor(s):: Cañon Jones, Hernán Alberto, Noble, Chris, Damsgård, Børge, Pearce, Gareth P.
Social network analysis was utilised to quantify the effect of short-term predictable (PD) and unpredictable (UD) feed delivery schedules of 10 days on behavioural interactions and the frequency and severity of fin damage in Atlantic salmon. Fin damage was only observed on the dorsal fin and its...
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...
Design and methodology of choice feeding experiments with ruminant livestock
Contributor(s):: Meier, Janina Sarah, Kreuzer, Michael, Marquardt, Svenja
The purpose of this review is to describe design and methodology of choice feeding experiments applied in ruminant livestock by taking into account their potential for different purposes and animal-, feed-, and set-up specific aspects. The first choice feeding experiments took place around 1900...
Effect of social feeding environment on the feeding behaviour of dairy cows and their willingness to consume a novel feed
Contributor(s):: Mainardes, G. A., DeVries, T. J.
Dairy cows are often exposed to novel situations and may show a strong behavioural response to novel feeds. To test the impact of social contact while feeding and the reaction of mature cows towards a novel feed we compared: 1) animals fed individually and 2) cows fed socially (in pairs). It was...
Stimuli from feed for sham dustbathing in caged laying hens
Contributor(s):: Moroki, Yuko, Tanaka, Toshio
Sham dustbathing is observed in caged hens, particularly near the feed trough, so it seems that feed acts as a stimulus for this behaviour, and the aim of this experiment was to test this. Commercial White Leghorn pullets that had been reared in group cages were housed at 17 weeks of age in...
Raw pet food as a risk factor for shedding of extended-spectrum beta-lactamaseproducing Enterobacteriaceae in household cats

Background Close contact between pets and owners provides the opportunity for transmission of antimicrobial resistant organisms like extended-spectrum beta-lactamase (ESBL)/AmpC beta-lactamase (AmpC)-producing Enterobacteriaceae, posing a risk to public health. Objectives To investigate...

Energy intake and expenditure of improvised explosive device detection dogs
| Contributor(s):: Phillips, S. P., Kutzner-Mulligan, J., Davis, M.
Improvised explosive device detection (IDD) dogs explore up to 40 km of land daily and therefore have energetic demands that may be above the National Research Council's requirement for working dogs. This study was designed to quantify metabolic energy intake (MEI) and total energy expenditure...
The avoidance of farmyards by European badgers Meles meles in a medium density population
| Contributor(s):: Mullen, E. M., MacWhite, T., Maher, P. K., Kelly, D. J., Marples, N. M., Good, M.
Mycobacterium bovis (TB) in cattle is a disease with far-reaching economic effects throughout Europe but especially in Great Britain and Ireland. Wildlife reservoirs, in particular the European badger Meles meles, continue to play an important role in the transmission of the disease, although the...
A test of "nutritional wisdom" in perch ( Perca fluviatilis) by self-selection of encapsulated macronutrients
| Contributor(s):: Brannas, E., Strand, A.
Developing optimal diets based on fish macronutrient requirements is an expensive and laborious task requiring years of research. However, many species of fish can compose a species-specific optimal diet from single source macronutrients in capsules through self-selection. Eurasian perch is a...
Quantitative assessment of human and pet exposure to Salmonella associated with dry pet foods
| Contributor(s):: Lambertini, E., Buchanan, R. L., Narrod, C., Ford, R. M., Baker, R. C., Pradhan, A. K.
Recent Salmonella outbreaks associated with dry pet foods and treats highlight the importance of these foods as previously overlooked exposure vehicles for both pets and humans. In the last decade efforts have been made to raise the safety of this class of products, for instance by upgrading...
