  • Effect of increasing temparature on space requirements of group housed finishing pigs (2012)

    Authors:Spoolder, H.A.M.; Aarnink, A.J.A.; Vermeer, H.M.; Riel, van J.W.
    In:Applied Animal Behaviour Science, 138(3-4), 229 - 239. ISSN 0168-1591.

    Abstract:

    For groups of pigs to cope adequately with their housing conditions they need sufficient static space (occupied by the body of the pig), activity space (for movement between different functional areas and behaviours relating to these) and interaction space (for appropriate social behaviour). Estimat

  • Review of wallowing in pigs: implications for animal welfare (2011)

    Authors:Bracke, M.B.M.; Spoolder, H.A.M.
    In:Animal Welfare, 20(3), 347 - 363. ISSN 0962-7286.

    Abstract:

    Most modern production systems, especially in temperate climates, do not offer wallowing facilities to pigs and, to date, this has neither generated much concern in welfare science nor public debate on pig welfare. Nevertheless, wallowing is a natural behaviour of pigs which may be important to them

  • EconWelfare geeft advies verhogen dierenwelzijn : dier & welzijn (2011)Open access

    Author:Spoolder, H.A.M.
    In:V-focus, 8(5A), 14 - 15. ISSN 1574-1575.

    Abstract:

    Binnen het Europese project EconWelfare zochten wetenschappers uit acht landen samen naar beleidsinstrumenten voor het verhogen van het dierenwelzijn. Daarbij werd de sociaal-economische impact in ogenschouw genomen. De projectgroep rondde deze zomer zijn onderzoek af en komt tot de conclusie dat er

  • Knowing Animals: Introduction and overview (2011)

    Authors:Miele, M.; Buller, H.; Veissier, I.; Bock, B.B.; Spoolder, H.A.M.
    In:Animal Welfare, 20(1), 1 - 2. ISSN 0962-7286.

  • Characteristics of biter and victim piglets apparent before a tail biting outbreak (2011)Open access

    Authors:Zonderland, J.J.; Schepers, F.; Bracke, M.B.M.; Hartog, den L.A.; Kemp, B.; Spoolder, H.A.M.
    In:Animal, 5(5), 767 - 775. ISSN 1751-7311.

    Abstract:

    Little is known about the characteristics of biters and victims before the appearance of a tail-biting outbreak in groups of pigs. This study aimed to characterise biters and victims (according to gender and performance) and to quantify their behavioural development during the 6 days preceding the t

  • Individual piglets' contribution to the development of tail biting (2011)Open access

    Authors:Zonderland, J.J.; Kemp, B.; Bracke, M.B.M.; Hartog, den L.A.; Spoolder, H.A.M.
    In:Animal, 5(4), 601 - 607. ISSN 1751-7311.

    Abstract:

    Conflicting hypotheses exist about the contribution of individual pigs to the development of a tail-biting outbreak, but there is limited quantitative information to support or dismiss them. This study aims to quantify the development of tail-biting behaviour at pen and individual piglet level, befo

  • Studies on preventive strategies and alternative treatments against roundworm in organic pig production systems (2011)

    Authors:Borgsteede, F.H.M.; Gaasenbeek, C.P.H.; Krimpen, van M.M.; Maurer, V.; Mejer, H.E.; Spoolder, H.A.M.; Thamsborg, S.M.; Vermeer, H.M.
    In:NJAS Wageningen Journal of Life Sciences, 58(3-4), 173 - 176. ISSN 1573-5214.

    Abstract:

    Organic and many ‘low input’ production standards for pigs require outdoor access, and as a consequence expose the animals to a wide range of potential endo- and ectoparasite infection sources. Conventional anthelmintics are used to control parasitic infections, but their preventive use is banned by

  • Welzijn: met de sectoren zoeken naar uitvoering : dier & welzijn (2010)Open access

    Authors:Spoolder, H.A.M.; Crijns, B.
    In:V-focus, 7(5A), 16 - 17. ISSN 1574-1575.

  • EU-welfare legislation on pigs (2010)Open access

    Authors:Mul, M.F.; Vermeij, I.; Hindle, V.A.; Spoolder, H.A.M.

  • Gender effects on tail damage development in single- or mixed-sex groups of weaned piglets (2010)

    Authors:Zonderland, J.J.; Bracke, M.B.M.; Hartog, den L.A.; Kemp, B.; Spoolder, H.A.M.
    In:Livestock Science, 129(1-3), 151 - 158. ISSN 1871-1413.

    Abstract:

    While extensive research on tail biting among pigs has focused on external factors (e.g., enrichment material), limited research has been conducted on internal factors (e.g., gender, breed or age), which may affect the predisposition of piglets to start tail biting. Furthermore, to test internal or
