  1. Facilitating ‘learning from mom how to eat like a pig’ to improve welfare of piglets around weaning

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

    Piglets in commercial husbandry are weaned abruptly and at a rather young age. Many weanling piglets are poorly adapted to ingest solid food, often resulting in a period of underfeeding. The underfeeding generally leads to a poor growth, diarrhoea occurrence and the development of damaging...

  2. Farm Animal Cognition-Linking Behavior, Welfare and Ethics

    Contributor(s):: Nawroth, C., Langbein, J., Coulon, M., Gabor, V., Oesterwind, S., Benz-Schwarzburg, J., von Borell, E.

  3. Feed restriction and tubes for environmental enrichment in growing mink—Consequences for behaviour and welfare

    Contributor(s):: Hansen, Steffen Werner, Møller, Steen Henrik, Damgaard, Birthe Marie

    This experiment compared the behaviour of mink during two different feeding routines; slightly restrictive (‘food free period’ of 6h) or standard (‘food free period’ of 2h), respectively, and the mink's use of two different types of occupational material; an attached tube made of wire mesh and a...

  4. Feeding enrichment in an opportunistic carnivore: the red fox

    Contributor(s):: Kistler, C., Hegglin, D., Wurbel, H., Konig, B.

    In captive carnivores, species-specific behaviour is often restricted by inadequate feeding regimens. Feeding live prey is not feasible in most places and food delivery is often highly predictable in space and time which is considerably different from the situation in the wild. As a result,...

  5. Ferrets’ (Mustela putorius furo) enrichment priorities and preferences as determined in a seven-chamber consumer demand study

    Contributor(s):: Reijgwart, Marsinah L., Vinke, Claudia M., Hendriksen, Coenraad F. M., van der Meer, Miriam, Schoemaker, Nico J., van Zeeland, Yvonne R. A.

    Knowledge of species-specific motivation and preferences for enrichment options is necessary to put in place an appropriate enrichment plan. This knowledge is currently lacking for ferrets. Therefore, seven female ferrets were consecutively housed in a seven-chamber closed economy consumer demand...

  6. Food distribution effects on the behaviour of captive common marmosets, Callithrix jacchus

    Contributor(s):: Bjone, S. J., Price, I. R., McGreevy, P. D.

  7. Food for Thought: Assessing Visitor Comfort and Attitudes toward Carcass Feeding at the ABQ BioPark Zoo

    Contributor(s):: Roth, Ellen K., Visscher, Nick C., Ha, Renee Robinette

    Enrichment is a key to keeping animals in zoos healthy and stimulated. For carnivores, the practice of feeding vertebrate animal carcasses, like those of goats or deer, or whole body prey animals like chickens or rabbits, can be an effective form of enrichment. While it is beneficial for animal...

  8. Food puzzles for cats: feeding for physical and emotional wellbeing

    Contributor(s):: Dantas, L. M. S., Delgado, M. M., Johnson, I., Buffington, C. A. T.

    Practical relevance: Many pet cats are kept indoors for a variety of reasons (eg, safety, health, avoidance of wildlife predation) in conditions that are perhaps the least natural to them. Indoor housing has been associated with health issues, such as chronic lower urinary tract signs, and...

  9. Foraging 'enrichment' as treatment for pterotillomania

    | Contributor(s):: Lumeij, J. T., Hommers, C. J.

    This study was performed to determine whether foraging 'enrichment' reduces self-directed psychogenic feather picking (pterotillomania) in parrots. A positive correlation between increased foraging time and improvement of feather score was hypothesised. Eighteen pterotillomanic African...

  10. Foraging enrichment for laboratory rats

    | Contributor(s):: Johnson, S. R., Patterson-Kane, E. G., Niel, L.

    The provision of foraging opportunities may be a simple way of improving an animal's welfare, but this approach has been neglected for laboratory rats (Rattus norvegicus). Standard housing contains little enrichment, and food is often provided ad libitum, which may result in inactivity and...

  11. Foraging in captive hamadryas baboons: implications for enrichment

    | Contributor(s):: Jones, M., Pillay, N.

    Many animals will work for food even if food is freely available or the animal is satiated, suggesting that foraging behaviour is inherently rewarding and that there is a behavioural need to forage. We investigated whether members of a hamadryas baboon (Papio hamadryas hamadryas) troop at the...

  12. Formalised review of environmental enrichment for pigs in relation to political decision making

    | Contributor(s):: Bracke, M. B. M., Zonderland, J. J., Lenskens, P., Schouten, W. G. P., Vermeer, H., Spoolder, H. A. M., Hendriks, H. J. M., Hopster, H.

    The EC Directive 2001/93/EC states that: "Pigs must have permanent access to a sufficient quantity of material to enable proper investigation and manipulation activities, such as straw, hay, wood, sawdust, mushroom compost, peat or a mixture of such, which does not compromise the health of the...

  13. Free-choice exploration increases affiliative behaviour in zebrafish

    | Contributor(s):: Graham, Courtney, von Keyserlingk, Marina A. G., Franks, Becca

    Cognitive stimulation has been shown to be rewarding and capable of eliciting positive emotions in several species. In contrast to the abundant learning and exploration opportunities available in nature, captive environments can be under-stimulating-with the potential to induce anhedonia and...

  14. Frequency of feeding enrichment and response of laboratory nonhuman primates to unfamiliar people

    | Contributor(s):: Baker, K. C., Springer, D. A.

    Although environmental enhancement plans for nonhuman primates vary between facilities, feeding enrichment represents a component of most programs. As part of a facility's feeding enrichment program, offering hand-fed food items by trained staff provides an opportunity for positive human...

  15. Fresh wood reduces tail and ear biting and increases exploratory behaviour in finishing pigs

    | Contributor(s):: Telkänranta, Helena, Bracke, Marc B. M., Valros, Anna

    Chewing and rooting are high behavioural priorities in pigs. Lack of suitable materials can lead to abnormal behaviours such as tail and ear biting. In commercial farming, slatted floors limit the use of straw, and various point-source objects have therefore been developed. The crucial challenge...

  16. From operant learning to cognitive enrichment in farm animal housing: bases and applicability

    | Contributor(s):: Manteuffel, G., Langbein, J., Puppe, B.

    This study has its basis in recent findings by our own and other laboratories and proposes a type of rewarded operant learning that seeks the detection of discriminatory cues as a cognitive enrichment in intensive husbandry systems. This type of cognitive enrichment has the ability to activate...

  17. Great ape cognition and captive care: Can cognitive challenges enhance well-being?

    | Contributor(s):: Clark, Fay E.

    Given the close genetic link between humans and nonhuman great apes, the well-being of the latter in captivity is understandably controversial. Behavioural signs of boredom, anxiety and stress in captive great apes have been linked to being reared in small groups or by humans, and by having a...

  18. Helping fish flourish: environmental enrichment for aquatic species

  19. Honest signalling through chemicals by elephants with applications for care and conservation.

    | Contributor(s):: Schulte, B. A., Freeman, E. W., Goodwin, T. E., Hollister-Smith, J., Rasmussen, L. E. L.

    Chemical signals are difficult to fake because they are often directly associated with phenotype and physiological condition, and hence likely to be honest signals for intraspecific communication. Chemical signals may be modified after release by the sender or by the environment. The proximate...

  20. Human interaction as environmental enrichment for pair-housed wolves and wolf-dog crosses

    | Contributor(s):: Mehrkam, L. R., Verdi, N. T., Wynne, C. D. L.

    Private nonhuman animal sanctuaries are often financially limited in their ability to implement traditional environmental enrichment strategies. One possible solution may be to provide socialized animals with human interaction sessions. However, the merit of human interaction as enrichment has...
