Individuality matters for substrate-size preference in the Nile tilapia juveniles
Contributor(s):: Maia, Caroline Marques, Volpato, Gilson Luiz
Preference tests have usually been used to identify nonhuman animal preferences for welfare purposes (environmental enrichment), but they are mostly at the group level—that is, group preferences for resources or environmental conditions. However, a more robust method was developed to analyze...
Astroturf as a dustbathing substrate for laying hens
Contributor(s):: Alvino, Gina M., Tucker, Cassandra B., Archer, Gregory S., Mench, Joy A.
Furnished cages for laying hens often contain an Astroturf (AT) pad which may be sprinkled with feed to promote foraging and dustbathing. We evaluated AT and AT plus feed (ATF) to determine if hens use these substrates for dustbathing. Hens (N=30) without prior exposure to substrate were housed...

The Development and Testing of a Procedure for Monitoring Visitor-Horse Interactions at Assateague Island National Seashore
Contributor(s):: Margaret Christine Ingle
Developing visitor impact indicators and associated monitoring techniques are critical first steps to sustain a balance between two national park mandates, protecting resources and providing recreation opportunities. The first paper of this thesis provides a comprehensive and organized assessment...
Influence of environmental stimuli on nest building and farrowing behaviour in domestic sows
Contributor(s):: Thodberg, K., Jensen, K. H., Herskin, M. S., Jorgensen, E.
The effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined using a 2 x 2 factorial design with 9 replicates of 4 multiparous sows. From 1 week prepartum until 2 weeks after farrowing, sows were penned individually in roofed 7.6 msuperscript 2...
Dustbathing by broiler chickens: a comparison of preference for four different substrates
Contributor(s):: Shields, S. J., Garner, J. P., Mench, J. A.
Leg abnormalities leading to lameness in broiler chickens are a serious welfare problem. Previous work in our laboratory demonstrated that providing broiler chickens with the opportunity to exercise by performing more natural behaviors (such as perching, walking up and down inclines and...
The relative preferences for feathers, straw, wood-shavings and sand for dustbathing, pecking and scratching in domestic chicks
Contributor(s):: Sanotra, G. S., Vestergaard, K. S., Agger, J. F., Lawson, L. G.
Chicks without experience of dustbathing showed no preference on days 2-7 of life when feathers, straw and wood-shavings were presented for pecking (Batch 1), but on days 8-13 feathers were preferred least. In chicks that were presented with sand, feathers and straw for pecking (Batch 2),...
Influence of environmental stimuli on maternal behaviour related to bonding, reactivity and crushing of piglets in domestic sows
Contributor(s):: Herskin, M. S., Jensen, K. H., Thodberg, K.
Effects of floor type (sand vs. concrete) and substrate type (straw feeder vs. no straw feeder) were examined in a 2 x 2 factorial experiment with 9 replicates of 4 multiparous sows. From one week prepartum until 13-15 days postpartum, sows were kept individually in 'get-away pens' with a 7.6...
The importance of a food feedback in rooting materials for pigs measured by double demand curves with and without a common scaling factor
| Contributor(s):: Holm, L., Jensen, M. B., Pedersen, L. J., Ladewig, J.
The first objective was to test if pigs prefer a rooting material with food feedback to one without, and if they prefer to search for food while rooting compared to obtaining food without rooting. For measuring preferences we used cross-points between double demand curves. Demand curves describe...
Preference testing of substrates by growing pigs
| Contributor(s):: Beattie, V. E., Walker, N., Sneddon, I. A.
The preferences of growing pigs for substrates were investigated by giving groups of 6 pigs a choice between 2 substrates in each test. The 7 substrates examined were concrete, mushroom compost (spent), peat, sand, sawdust, straw and woodbark. 13 comparisons of pairs of substrates were tested...
