Extract

Previous work has shown that an acute mid-partum can inhibit oxytocin secretion and prolong delivery in the pig, an effect that is opioid-mediated (Lawrence et al., 1992). However, where gilts were given 5 days to adapt to the farrowing crate, there was little indication that the crate interfered with oxytocin secretion or the progress of parturition relative to gilts farrowing in pens with straw bedding (Lawrence et al., 1995). This experiment aimed to directly assess the extent to which crates or pens affect opioid-control of oxytocin (OT) secretion as a means of measuring stress in the parturient gilt.
