When this is taken into consideration, the common perception among horse owners that the chestnut coat colour is associated with adverse...

  6. Animal exploitation during the Old Kingdom in Egypt: contribution from Ayn Asil (Dakhla Oasis)Exploitation animale a l'Ancien Empire en Egypte: les apports d'Ayn Asil (oasis de Dakhla)

    Contributor(s):: Lesur, J.

    At the end of the Old Kingdom in Egypt, food production relies on a dense agriculture in the Delta and the Nile valley as well as on livestock herding and fishing. The situation is however different in the Western Desert which undergoes a strong aridification. Archaeozoological remains coming...

  7. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

  8. Hunger in pregnant sows: effects of a fibrous diet and free access to straw

    Contributor(s):: Jensen, M. B., Pedersen, L. J., Theil, P. K., Knudsen, K. E. B.

    Fibrous diets and the provision of straw have been suggested to reduce feeding motivation in pregnant sows. The present experiment investigated the separate and interactive effects of a fibrous diet and ad libitum access to straw on feeding motivation, oral behaviour and plasma levels of...

  9. Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae

    Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.

    Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...

  10. Dustbathing, pecking and scratching behaviours of laying hens in furnished cages are enhanced by the presence of rubber mats and litter distribution

    Contributor(s):: Guinebretiere, M., Michel, V., Arnould, C.

    Furnished cages for laying hens exist in a wide variety of sizes and designs and should be equipped to allow hens to express some of their behavioural priorities. European Council Directive 1999/74/EC stipulates that litter must be provided for pecking and scratching but the type of litter and...

  11. Stereotypic mice are aggressed by their cage-mates, and tend to be poor demonstrators in social learning tasks

    Contributor(s):: Harper, L., Choleris, E., Ervin, K., Fureix, C., Reynolds, K., Walker, M., Mason, G.

    Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social...

  12. Retracting inconclusive research: lessons from the Seralini GM maize feeding study

    Contributor(s):: Resnik, D. B.

    In September 2012, Gilles-Eric Seralini and seven coauthors published an article in Food and Chemical Toxicology claiming that rats fed Roundup-resistant genetically modified maize alone, genetically modified maize with Roundup, or Roundup for 2 years had a higher percentage of tumors and kidney...

  13. Effects of stage of gestation at mixing on aggression, injuries and stress in sows
