  5. Effects of environmental enrichment and loose housing of lactating sows on piglet behaviour before and after weaning

    Contributor(s):: Oostindjer, Marije, van den Brand, Henry, Kemp, Bas, Bolhuis, J. Elizabeth

    Weaning of piglets in commercial husbandry systems is earlier and more abrupt than would happen under natural conditions, resulting in low feed intakes and health and welfare problems in the immediate postweaning period. Piglets in commercial systems generally have limited opportunities to learn...

  6. Effects of feed- and water-based enrichment on activity and cannibalism in Muscovy ducklings

    | Contributor(s):: Riber, A. B., Mench, J. A.

    Cannibalism is a major problem for commercial production of Muscovy ducks (Cairina moschata). Surprisingly little is known about the ontogeny of cannibalism in ducks or how to reduce/prevent the problem in a welfare-friendly way. The preventative method typically used by the industry is...

  7. Effects of feeding enrichment on the behaviour and welfare of captive waldrapps (Northern bald ibis) ( Geronticus eremita )

    | Contributor(s):: Vargas-Ashby, H. E., Pankhurst, S. J.

    One of the contributing factors leading to the development of serious foot problems such as bumblefoot (pododermatitis) in captive birds is an abnormally sedentary lifestyle. This study investigated the effects of feeding enrichment on the activity levels of a captive colony of seven Waldrapps or...

  8. Effects of fermentable starch on behaviour of growing pigs in barren or enriched housing

    | Contributor(s):: Bolhuis, J. E., Brand, H. van den, Bartels, A. C., Oostindjer, M., Borne, J. J. G. C. van den, Kemp, B., Gerrits, W. J. J.

    Fermentation of resistant starch might prolong satiety, and, therefore, positively affect behaviour and welfare of restrictedly-fed pigs. The impact of a potentially satiating diet likely depends on housing conditions, such as the availability of rooting material which may serve as a substrate...

  9. Effects of foraging enrichment on the behaviour of parrots

    | Contributor(s):: Coulton, L. E., Waran, N. K., Young, R. J.

    The purpose of this study was to enrich parrot enclosures by creating foraging opportunities appropriate for the species and to investigate the possible preference for a variable versus a constant food supply. The subjects were housed as single-species groups, which comprised 2 male and 2 female...

  10. Effects of habitat complexity on the aggressive behaviour of the American lobster ( Homarus americanus ) in captivity

    | Contributor(s):: Cenni, F., Parisi, G., Gherardi, F.

    The American lobster, Homarus americanus, is one of the most economically valuable crustacean decapods worldwide, being mostly exploited to foster the live animal industry. Lobsters are typically held in storage facilities where individuals may suffer due to the repeated combats among each other....

  11. Effects of loose housing and the provision of alternative nesting material on peri-partum sow behaviour and piglet survival

    | Contributor(s):: Bolhuis, J. E., Raats-van den Boogaard, A. M. E., Hoofs, A. I. J., Soede, N. M.

    Sows are strongly motivated to perform nestbuilding behaviour before parturition. This behaviour is often restricted in commercial systems due to confinement of the sow and lack of suitable nesting material to be used on slatted floors. This study aimed to investigate effects of loose vs. crated...

  12. Effects of panels and perches on the behaviour of commercial slow-growing free-range meat chickens

    | Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.

    Environmental enrichment has the potential to benefit the welfare of farm animals. In poultry, panels and perches are two of the most commonly used forms of enrichment but few studies have determined their effects under commercial conditions. The aim of this work was to assess the impact of these...

  13. Effects of positive interaction with caretakers on the behaviour of socially housed common marmosets ( Callithrix jacchus )

    | Contributor(s):: Manciocco, A., Chiarotti, F., Vitale, A.

    Every aspect of the life of the captive non-human primates should be carefully attended to, as updated refinement concept recommends. Interaction with humans as environmental enrichment for these animals is believed to be of value, but it has been subject to little quantitative evaluation. This...

  14. Effects of single-use and group-use enrichment on stereotypy and intragroup aggressive and affiliative behaviors of a social group of squirrel monkeys (Saimiri sciureus) at the Singapore Zoo

    | Contributor(s):: Sha, J., Han, S., Marlena, D., Kee, J.

    Four food-based enrichment devices were used to test the effects of single-use and group-use enrichment devices on stereotypy, intragroup aggression, and affiliation in a compatible group of 5 squirrel monkeys (Saimiri sciureus). All enrichment devices were found to reduce overall stereotypic...

  15. Effects of three food enrichment items on the behavior of black lemurs ( Eulemur macaco macaco ) and ringtail lemurs ( Lemur catta ) at the Henson Robinson Zoo, Springfield, Illinois

    | Contributor(s):: Maloney, M. A., Meiers, S. T., White, J., Romano, M. A.

    This study tested 3 food enrichment items mentioned in a laboratory primate newsletter with 6 adult Eulemur macaco and 3 adult Lemur catta to examine whether the items would affect the behavior of the lemurs. The results suggest that Food Enrichment Item 3 (a wire box filled with whole grapes,...

  16. Efficacy of an interactive apparatus as environmental enrichment for common bottlenose dolphins (Tursiops truncatus)

    | Contributor(s):: Lauderdale, L. K., Miller, L. J.

  17. Efficacy of repellent-treated structural barriers for Richardson's ground squirrels (Urocitellus richardsonii (Sabine)) and house mice (Mus musculus L.)

    | Contributor(s):: DeLiberto, Shelagh T., McLean, Hailey E., Werner, Scott J.

    The worldwide presence of vertebrate pests such as rodents has created a need for non-lethal control methods that can be applied to integrated pest management plans. Chemical repellents are often a useful wildlife management tool as they can be directly applied to a commodity or structure to...
