  1. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

The present study assessed how stocking density affects growth performance (final body weight, SGR, FCR), physiological (plasma...

  7. Assessment of acute pain experienced by piglets from ear tagging, ear notching and intraperitoneal injectable transponders

    Contributor(s):: Leslie, E., Hernandez-Jover, M., Newman, R., Holyoake, P.

    Suckling piglets are routinely identified to assist with their day-to-day management. A total of 120 suckling piglets were used to determine and compare the short-term pain responses to a number of identification methodologies, including: ear notching, ear tagging and intraperitoneal injection...

  8. Behaviour of growing lambs housed on straw or woodchip bedding materials and their preference for floor type

    Contributor(s):: Wolf, B. T., Molloy, H. R. B., Trayte, M. J., Rose, M. T.

    Straw is widely used as a bedding material for housed sheep, but alternatives are needed in regions where straw is expensive or in short supply. The aim of this work was to compare time budgets, growth and food intake of growing, finishing lambs housed on either woodchip or straw bedding...

  9. Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs

    Contributor(s):: Wall, D., Paterson, B., Mohan, R.

    Behaviour of juvenile mud crabs, Scylla serrata (70-90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better understand the role that...

  10. Effect of different rearing systems and pre-kindling handling on behaviour and performance of rabbit does

    Contributor(s):: Mugnai, C., Bosco, A. dal, Castellini, C.

    The aim of this study was to ascertain how collective cage and pre-kindling handling (training does to go into their own nest) practices, in comparison to standard housing (single cage rearing), modify the behaviour and the performance of rabbit does. To this aim, 40 nulliparous New Zealand White...

  11. Effect of feed barrier design and feed space allowance on performance and behavioural parameters in dairy cows

    Contributor(s):: O'Connell, N. E., Ferris, C. P., Patterson, D. C., Mayne, C. S.

    Sixty mid-lactation Holstein-Friesian dairy cows (40 multiparous (cows) and 20 primiparous (heifers)) were allocated to one of four treatments in a 2x2 factorial design arrangement. The treatments involved two feed barrier space allowances (56 cm/animal ("high") or 20 cm/animal ("low")) and two...

  12. Effects of early contact between non-littermate piglets and of the complexity of farrowing conditions on social behaviour and weight gain

    Contributor(s):: Kutzer, T., Bunger, B., Kjaer, J. B., Schrader, L.

    In this study we tested if contact possibilities between non-littermate piglets and complexity of farrowing conditions affect the pre- and post-weaning behaviour, weight gain and skin lesions of piglets. Suckling sows were either kept in a group housing system (GH), in a single pen loose housing...

  13. Experience of moderate bedding affects behaviour of growing pigs

    Contributor(s):: Munsterhjelm, C., Peltoniemi, O. A. T., Heinonen, M., Halli, O., Karhapaa, M., Valros, A.

    Effects of early substrate-enrichment on behaviour and productivity of pigs were evaluated in a trial with four siblings as the experimental unit. Pens either were (=E) or were not (=0) moderately bedded with wood shavings and chopped straw during suckling (0-4 weeks of age), nursery (5-9 weeks)...
