  4. Immunocastration with Improvac™ reduces aggressive and sexual behaviours in male pigs

    Contributor(s):: Brewster, Veronica, Nevel, Amanda

    Surgical castration of male pigs is a common practice to reduce the risk of boar taint, an accumulation of pheromones in the muscles of pigs giving an undesirable odour to the pork of entire boars. Castration is not widely practiced in the UK for welfare reasons and indeed, assurance schemes will...

  5. Effects of neonatal castration on social behaviour, human–animal relationship and feeding activity in finishing pigs reared in a conventional or an enriched housing

    Contributor(s):: Tallet, Céline, Brilloüet, Armelle, Meunier-Salaün, Marie-Christine, Paulmier, Valérie, Guérin, Carole, Prunier, Armelle

    Raising entire males is already common in a few European countries. It has the advantage of avoiding the pain of castration. Entire males have also a better food conversion. However, they would be more aggressive than castrates which causes welfare troubles. The consequences for human–animal...

  6. Do rubber rings coated with lignocaine reduce the pain associated with ring castration of lambs?

    Contributor(s):: Stewart, Mairi, Beausoleil, Ngaio J., Johnson, Craig B., Webster, James R., Schütz, Karin E., Cox, Neil, Stafford, Kevin J.

    To facilitate the wider use of pain relief on-farm, practical ‘farmer friendly’ methods for administering pain relief are necessary. This proof of concept study evaluated the efficacy of rubber rings coated with local anaesthetic (LA, lignocaine) for providing pain relief in lambs castrated 4...

  7. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 2. Responses related to stress, health and productivity

    Contributor(s):: Petherick, J. Carol, Small, Alison H., Mayer, David G., Colditz, Ian G., Ferguson, Drewe M., Stafford, Kevin J.

    Tension banding castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the banders as a humane castration method. Two experiments were conducted, under tropical conditions using Bos indicus bulls comparing tension banding (Band) and...

  8. A comparison of welfare outcomes for weaner and mature Bos indicus bulls surgically or tension band castrated with or without analgesia: 1. Behavioural responses

    Contributor(s):: Petherick, J. Carol, Small, Alison H., Mayer, David G., Colditz, Ian G., Ferguson, Drewe M., Stafford, Kevin J.

    Tension-band castration of cattle is gaining favour because it is relatively simple to perform and is promoted by retailers of the devices as a humane castration method. Furthermore, retailers encourage delaying castration to exploit the superior growth rates of bulls compared with steers. Two...

  9. Comparison of the effects of weaning and castration when conducted separately or in combination on the behaviour of crossbred beef cattle

    Contributor(s):: Lambertz, Christian, Farke-Röver, Antje, Moors, Eva, Gauly, Matthias

    The objective of the present study was to evaluate the behavioural effects of Burdizzo castration of crossbred beef calves when weaned and castrated separately (castrated 8 weeks after weaning) or in combination. Over two consecutive years a total of 111 Limousin×Simmental male calves were...

  10. Social transmission of physiological and behavioural responses to castration in suckling Merino lambs

    Contributor(s):: Colditz, Ian G., Paull, David R., Lee, Caroline

    In social species like sheep, social context can modify both physiological and behavioural responses to stressors and normal behavioural patterns. Presence of conspecifics can ameliorate responses to noxious stimuli, an effect termed social buffering, whereas the presence of a distressed...

  11. A review of pain assessment techniques and pharmacological approaches to pain relief after bovine castration: Practical implications for cattle production within the United States

    Contributor(s):: Coetzee, Johann F.

    Castration of male calves destined for beef production is a common livestock management practice in the United States amounting to approximately 7 million procedures per year. Recently there has been renewed interest in identifying methods to reduce pain associated with dehorning and castration....

  12. Impact of single-sex and mixed-sex group housing of boars vaccinated against GnRF or physically castrated on body lesions, feeding behaviour and weight gain

    Contributor(s):: Schmidt, Tatjana, Calabrese, Justin M., Grodzycki, Mario, Paulick, Marleen, Pearce, Michael C., Rau, Franziska, von Borell, Eberhard

    Physical castration of male piglets is common practice in many countries for the control of boar taint. A vaccine against GnRF (Improvac®) is licensed in Europe as an alternative to this painful procedure. Vaccinated pigs are known to behave like entire males up to the second vaccination,...

  13. Castration induced pain in pigs and other livestock

    Contributor(s):: Rault, Jean-Loup, Lay, Donald C., Marchant-Forde, Jeremy N.

    Castration of male livestock being reared for meat has long been practiced, to prevent unwanted breeding, make management and handling easier, and to improve meat quality. However, castration is a painful procedure for the animal and has increasingly come under scrutiny from animal welfare...

  14. Qualitative Behavioural Assessment of Bos indicus cattle after surgical castration

    Contributor(s):: Vindevoghel, Thinza V., Fleming, Patricia A., Hyndman, Timothy H., Musk, Gabrielle C., Laurence, Michael, Collins, Teresa
