Plasma free cortisol concentrations were measured in 24 primiparous sows housed from day 104 after mating up to day 2 after parturition. Concentrations were measured in 22 of these sows during days 2-29 of lactation, housed in either commercial farrowing crates, or farrowing pens with straw. The mortality and growth data of litters from birth to weaning were recorded. Mean plasma free cortisol concentration was higher in sows in crates, compared with penned sows on the first day of the experiment (8.2 and 5.8 nmol/litre, respectively) and on day 28 of lactation (5.6 and 4.0 nmol/litre). The data suggest that type of housing around parturition and during lactation may have only limited effects on the welfare of sows, providing that lactation is no longer than 28 days. On days 21 and 24, there were no effects on free cortisol concentrations and no response to exogenous ACTH, respectively. However, on day 28, there were mean increases in the concentrations of free cortisol of about 150% and 60
