  • Summary of responses to swine biomechanics

    Hello members,

    I hereby bring you the summary of replies for my question from March 19th on gait analysis on swine. For your orientation my original posting sounded as follows:

    For my Ph.D. I'm doing a biomechanical analysis of the locomotion of pigs
    on different surfaces with special focus on slipping. I'll be combining
    video recordings with force plate measurements.
    In my literature searches I have come across a lot of equine research
    (Drevemo, Hjerten, Holmström, Barrey, Back, Merkens, Schamhardt, Leach and
    others) a little on dogs (DeCamp, Hottinger and others), and a bit on cattle
    (Phillips, Morris, Telezhenko), but I haven't found anything with swine as
    biomechanic subject animals.
    For the moment I'm working on a verification of joint rotation centres of
    both forelimb (shoulder, elbow, carpal, fetlock) and hindlimb (hip, stifle,
    tarsal, and fetlock).
    I'm interested in getting in contact with others that use swine as model
    animals for biomechanical research, and also maybe learn about references
    that discuss the joint rotation centres in detail.

    I would like to thank those who responded to my question. It seems that not many are researching the area of swine biomechanics, as only two of the responses directly concerned swine.

    The responses were:

    >From Johann Meierl, Institut fuer Tieranatomie der Universitaet Muenchen:
    I am turning to you on behalf of the email you submitted to Biomech-L. I
    am a veterinarian and I think this is a valuable and important study you
    are undertaking. But I have to admit that I cannot give you any further
    hints on literature concerning gait analysis in swine.
    The reason why I turn to you is that I wanted to ask you whether it
    would be possible to get the cattle gait analysis citations you have
    I appreciate your efforts on my behalf and would like to thank you very
    much in advance.

    >From Vincent Bels, Centre Agronomique de Recherches Appliquées du Hainaut:
    We are working on the behaviour of pigs in different conditions and begun a
    kinematic study of locomotion of pigs on hard substratum (cement) and soft
    litter . We are using high-speed video camera (NAC-500) and image analysis
    based on frame grabbing with imageproplus.
    For different reasons, we have not yet go further into our analysis, but
    would be interested by any contact

    >From John Polk, Harvard University:
    I've recently run a few young pigs on treadmills recently to collect joint
    angle and limb movement data on their hindlimbs during walking and
    trotting. I would recommend using very young pigs as they will be easier
    to train and will be more manageable than adults. We've found sheep to be
    far more tractable as research subjects and treadmill runners. Best of
    luck with your research, I look forward to your summary.

    >From Ken Soltz, Tekscan:
    A colleague of mine who is on the Biomechanics list passed along your
    question. I have forwarded some articles (attached) which discuss the use of pressure
    plates in swine research. They are all using a pressure mapping tool made by my company, Tekscan.

    (Ken attached four articles, two of which concerned horses, one concerned cats, and the last concerned sheep. Below I bring you the reference on the sheep article)

    Thank you again to the respondents.
