Oxytocin, prolactin and somatostatin in lactating sows: associations with mobilisation of body resources and maternal behaviour

Popis výsledku v původním jazyce

The aim of the present study was to investigate how oxytocin, prolactin and somatostatin during nursings relate to maternal characteristics of sows. Undisturbed nursing behaviour and sow-piglet nasal contacts of 21 lactating sows were recorded on day 13of lactation, and hormonal status was assessed during three successful nursings on day 14. Piglet and litter growth (days 8-15), sow weight loss (days 1-15) and catabolic state (measured as NEFA on day 7), as well as number of successful nursings on day13were used as measures of mobilisation of sow body resources. Nasal contacts and sow behaviour facilitating udder massage were used as measures of positive piglet-directed behaviours. Concentrations of oxytocin were higher, those of prolactin lower and those of somatostatin similar during nursings compared to samples taken 15 min after nursing. Oxytocin peaked during most nursings and prolactin increased gradually after nursings.
