Extract

Maternal oestrogen and progesterone have been shown to be important in the initiation of maternal behaviour (e.g. Shipka and Ford, 1991). It has also been suggested by Csermely and Nicosia (1991) that there is an association between social rank and the performance of maternal behaviour. This study investigated the relationships between social behaviour during pregnancy, levels of sex steroids around parturition and the level of maternal care shown by gilts. Sows and gilts are generally housed in farrowing crates during parturition and lactation. This study also ascertained whether or not the farrowing environment affected sex steroid concentrations.
