    Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in...

  8. Environmental complexity and use of space in slow growing free range chickens

    Contributor(s):: Rodriguez-Aurrekoetxea, Ane, Leone, Erin Hoerl, Estevez, Inma

    Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...

  9. The effect of pen design on free space utilization of sows group housed in gestation pens equipped with free access stalls

    Contributor(s):: Rioja-Lang, Fiona C., Hayne, Stephanie M., Gonyou, Harold W.

    This study investigated the implementation of walk-in/lock-in stalls (free access stalls) for group housed sows. The objectives were to compare two different pen configurations (‘I-pen’ vs. ‘T-pen’) by determining the proportion and type (size/parity) of sows that used the free space areas, and...

  10. Do hens have friends?

    Contributor(s):: Abeyesinghe, Siobhan M., Drewe, Julian A., Asher, Lucy, Wathes, Christopher M., Collins, Lisa M.

    Recent interest in positive welfare has encouraged consideration of the formation of socio-positive relationships in farmed species which may provide a means by which to manage positive states. We investigated in detail the existence of dyadic preferential associations in small groups of domestic...

  11. The behaviour of gestating dairy ewes under different space allowances

    Contributor(s):: Averós, Xavier, Lorea, Areta, de Heredia, Ignacia Beltrán, Ruiz, Roberto, Marchewka, Joanna, Arranz, Josune, Estevez, Inma

    Provision of adequate housing is essential to assure the welfare of farm animals. One relevant aspect is space allowance, due to potential consequences on the behaviour and welfare of animals. The objective of this study was to determine the effect of space allowance on the behaviour and...

  12. Turning around by pregnant sows

    Contributor(s):: Bøe, Knut Egil, Cronin, Greg M., Andersen, Inger Lise

    Two experiments were conducted to investigate the effects of reducing pen width on turning around by sows. While pregnant sows were studied in both experiments, our overriding objective was to investigate the relationship between space on turning around by farrowing/lactating sows in pens and...

  13. Space allowance and the behaviour of captive southern hairy-nosed wombats (Lasiorhinus latifrons)

    Contributor(s):: Descovich, Kristin A., Lisle, Allan T., Johnston, Stephen, Phillips, Clive J. C.

    Captive southern hairy-nosed wombats (Lasiorhinus latifrons) often display indicators of sub-standard welfare, including aggression and stereotypical pacing. To determine if space availability influences the welfare of wombats, the behaviour of three groups of L. latifrons (n=3) was studied in...

  14. Shelter use of familiar and unfamiliar groups of juvenile European catfish Silurus glanis

    Contributor(s):: Slavík, Ondřej, Maciak, Matúš, Horký, Pavel

    Within aquaculture systems, shelters are often used to reduce cannibalism, minimise energy consumption, accelerate the start of exogenous feeding, support growth, and improve survival and welfare. However, stronger competition for shelters in aquaculture systems relative to that under wild...

  15. Neighbourhood analysis as an indicator of spatial requirements of broiler chickens

    Contributor(s):: Buijs, Stephanie, Keeling, Linda J., Vangestel, Carl, Baert, Jeroen, Tuyttens, Frank A. M.

    The appropriate stocking density for broiler chickens is a much discussed topic in animal welfare. To determine at which stocking density the level of crowding becomes aversive to 4–6-week-old broiler chickens, spatial distribution and behaviour of groups stocked at 8, 19, 29, 40, 45, 51, 61 or...
