The Behavioural Effects of Innovative Litter Developed to Attract Cats
| Contributor(s):: Jennifer Frayne, Sarah MacDonald Murray, Candace Croney, Elizabeth Flickinger, Michelle Edwards, Anna Kate Shoveller
Urination and/or defecation outside a designated location has been reported as the most common behavioural reason for surrendering a cat and comprises approximately 30% of cat intakes to shelters. The objective of this study was to determine whether cats would increase in-box elimination when...
Predicting feather damage in laying hens during the laying period. Is it the past or is it the present?
| Contributor(s):: de Haas, Elske N., Bolhuis, J. Elizabeth, de Jong, Ingrid C., Kemp, Bas, Janczak, Andrew M., Rodenburg, T. Bas
Feather damage due to severe feather pecking (SFP) in laying hens is most severe during the laying period. However, SFP can develop at an early age and is influenced by early rearing conditions. In this study we assessed the risk factors during the rearing and laying period for feather damage at...
Litter competition during nursings and its effect on sow response on Day 2 postpartum
| Contributor(s):: Bozděchová, Barbora, Illmann, Gudrun, Andersen, Inger Lise, Haman, Jiří, Ehrlenbruch, Rebecca
The aim of the present study was to assess neonatal sibling competition during nursing on Day 2 postpartum (pp) as well as its effect on the sow's responses. A total of 41 healthy loose-housed sows and their piglets were directly observed and video recorded for 6h on Day 2 pp. Piglet behaviours...
The choice of litter material to promote pecking, scratching and dustbathing behaviours in laying hens housed in furnished cages
| Contributor(s):: Guinebretière, Maryse, Beyer, Helen, Arnould, Cécile, Michel, Virginie
Since 2012 in the EU, cages for the housing of laying hens must provide nests, perches and a pecking and scratching area to promote natural behaviours and enhance animal welfare. Previous studies highlighted the difficulty of finding adequate materials for pecking and scratching areas in such...
Influence of origin litter on social rank, agonistic behaviour and growth performance of piglets after weaning
| Contributor(s):: Fels, Michaela, Hoy, Steffen, Hartung, Jörg
In pig production, mixing of piglets after weaning is a common management practice often leading to severe fighting aimed at establishing a social hierarchy. The intention of our study was to investigate whether social rank of piglets obtained by fighting within 3 days after weaning and mixing...
Access to litter during rearing and environmental enrichment during production reduce fearfulness in adult laying hens
| Contributor(s):: Brantsæter, Margrethe, Tahamtani, Fernanda M., Nordgreen, Janicke, Sandberg, Ellen, Hansen, Tone Beate, Rodenburg, T. Bas, Moe, Randi Oppermann, Janczak, Andrew Michael
Exaggerated fear-reactions are associated with injurious flying, smothering, feather pecking and other events that compromise animal welfare in laying hens. The aim of this study was to test the hypothesis that chicks with access to litter during the first five weeks of life would be less fearful...
Location tracking of individual laying hens housed in aviaries with different litter substrates
| Contributor(s):: Campbell, Dana L. M., Karcher, Darrin M., Siegford, Janice M.
The laying hen industry is phasing out conventional cages in favor of other housing systems such as the aviary – designed to improve hen welfare by providing additional space and resources including a litter area. However, we do not know whether individual hens significantly vary in the time they...
The sex ratio of a litter affects the behaviour of its female pigs until at least 16 weeks of age
| Contributor(s):: Seyfang, Jemma, Plush, Kate J., Kirkwood, Roy N., Tilbrook, Alan J., Ralph, Cameron R.
There are sex differences in behaviour with males tending to be more aggressive and less fearful than females. When females are treated with androgens they display more aggressive, male like, behaviours and this suggests that androgen exposure has a role in the development of aggression. Female...
Playful pigs: Evidence of consistency and change in play depending on litter and developmental stage
| Contributor(s):: Brown, S. M., Peters, R., Nevison, I. M., Lawrence, A. B.
Play behaviour in pre-weaned piglets has previously been shown to vary consistently between litters. This study aimed to determine if these pre-weaning litter differences in play behaviour were also consistent in the post weaning period. Seven litters of commercially bred piglets were raised in a...
A prospective exploration of farm, farmer, and animal characteristics in human-animal relationships: an epidemiological survey
| Contributor(s):: Roches, A. de B. des, Veissier, I., Boivin, X., Gilot-Fromont, E., Mounier, L.
Human-animal relationships are essential for dairy farming. They affect work comfort and efficiency, as well as milk production. A poor human-animal relationship can result in stress and accidents to both animals and caretakers and needs to be improved. However, many studies have demonstrated...
The contribution of broiler chicken welfare certification at farm level to enhancing overall animal welfare: the case of Brazil
| Contributor(s):: Souza, A. P. O., Molento, C. F. M.
The intensification of farm animal welfare debate has led to an increasing number of certification schemes covering this issue; however, there are concerns about the contribution of these schemes in improving welfare. The aims of this study were to identify certification schemes for broiler...
Effect of different management techniques to enhance colostrum intake on piglets' growth and mortality
| Contributor(s):: Muns, R., Manteca, X., Gasa, J.
An experiment was conducted to study the effect four different management techniques to enhance colostrum intake had on piglet and litter performance. Treatments were performed on piglets born weighing 1.30 kg or less (SP) within 6 h of birth: control group (CON); split-nursing of the litter for...

Association between resting behaviour and live weight gain in dairy heifers housed in pens with different space allowance and floor type
| Contributor(s):: Mogensen, L., Krohn, C. C., Sorensen, J. T., Hindhede, J., Nielsen, L. H.
The hypothesis that daily liveweight gain is associated with resting behaviour in heifers was studied. The study was based on 2 experiments conducted on Danish commercial dairy farms with Danish Friesian heifers (300-400 kg) in the winter periods. Group size was 5-6 heifers/pen. Experiment A,...
Behaviour and leg injuries in dairy cows kept in cubicle systems with straw bedding or soft lying mats
| Contributor(s):: Wechsler, B., Schaub, J., Friedli, K., Hauser, R.
In order to reduce straw input, soft lying mats are used increasingly instead of straw bedding in cubicle systems for dairy cows. This study aimed at comparing different types of soft lying mats with straw bedding regarding cow behaviour and leg injuries. Data were collected on 5 farms with straw...
Effects of straw bedding and high fibre diets on the behaviour of floor fed group-housed sows
| Contributor(s):: Whittaker, X., Edwards, S. A., Spoolder, H. A. M., Lawrence, A. B., Corning, S.
Twenty groups of 7 multiparous Landrace x Large White sows were used in a 2 x 2 factorial design to investigate the effects on behaviour of floor feeding sows the same daily weight of isoenergetic conventional (C) or high fibre (H containing 600 g of unmolassed sugar beet pulp/kg diet) pregnancy...
Nursing behaviour of sows during 5 weeks lactation and effects on piglet growth
| Contributor(s):: Valros, A. E., Rundgren, M., Spinka, M., Saloniemi, H., Rydhmer, L., Algers, B.
The main goal of this study was to investigate the effect of sow nursing behaviour on piglet liveweight gain and within-litter variation (WLV) in piglet liveweight gain under as naturalistic conditions as possible. In order to achieve this, patterns of sow nursing behaviour and piglet liveweight...
Preference testing in intensively kept meat production rabbits for straw on wire grid floor
| Contributor(s):: Morisse, J. P., Boilletot, E., Martrenchar, A.
384 hybrid commercial breed rabbits were assigned to 16 pens of 1.6 msuperscript 2 (15 rabbits/msuperscript 2). Eight pens used as controls had an all-wire floor, while in 8 other pens, rabbits could choose between a wire floor or a deep litter topped up once a week and completely replaced once...
