  • Best practice for on-farm euthanasia of spent layer hens

    Best practice euthanasia coverAt the end of lay, spent layers have historically been caught, crated and transported to various poultry processing plants where they are processed for use in a variety of human food products. Due to the reduced commercial value of such products and the imposed charges applied to collecting spent layers, egg producers are looking for alternative ways of removing spent layer hens.

  • The effects of time off feed and water on the welfare of spent laying hens - Phase 2: Behavioural indicators

    1UM122AThis project aimed to equate physiological changes induced by water deprivation with behavioural changes in order to understand its welfare implications for the transport of spent laying hens.
    The results presented in this report, in accordance with the previous study (MCCP: 2009-320), questions the welfare of hens that have water withdrawn for 24h or longer. It should be recognised that factors other than feed and water deprivation are likely to influence hen welfare during transport, such as the health status of the hens prior to loading, their body condition, stress of handling, social stress of mixing, duration of transport and the weather during transport and lairage. The threshold indicative of acceptable welfare remains debatable depending on value-based judgements.

  • Composting Every Day Mortalities and Other Wastes from Layer Farms

    1 ActivitiesComposting is a viable alternative method for disposing of daily mortalities, spent hens, egg and other waste produced on Australian egg farms. Under controlled systems, with the correct management, good results can be achieved and a safe, nutrient-rich soil amendment produced for reuse on-farm or sale to other farmers. This project involved on-farm compost trials at nine farms across Australia.
