What triggers a pig to Farrow?

28 мая 2019 г. · Farrowing trigger. The piglets are responsible for their birth date by secreting corticosteroids – in response to reducing nutrient availability . The trigger for farrowing (parturition) to start comes from the piglets, not the sow. As the foetuses start to outgrow their nutrient supply from the placenta, stress hormones are released which set off a hormonal cascade leading to the start of farrowing. Occasionally sows will attack their own piglets – usually soon after birth – causing injury or death. In extreme cases, where feasible, outright cannibalism will occur and the sow will eat the piglets. The development of this behaviour is often complex and difficult to stop and can cause significant losses.
