    Lameness is a common health and welfare problem in sows. Little has been published about behavioral changes in lame sows. Ketoprofen is an effective non-steroidal anti-inflammatory drug used to treat non-infectious locomotor disorders in pigs. The aim of this study was to determine the effect of lameness and lameness-related pain on the behavior of sows. To evaluate this effect, we studied whether pain alleviation with ketoprofen and clinical relief of lameness were associated with changes in behavior. We allocated randomly 13 lame, early pregnancy sows in three treatment groups receiving either ketoprofen 4 mg/kg, ketoprofen 2 mg/kg (these two groups were pooled for statistical analyses) or placebo. The animals were treated orally for 5 days and lameness scored before and on the last day of the treatment. Lameness was assessed with a 5-grade scoring system and behavior by scan sampling method. A clinically healthy, non-lame control sow was paired with each lame sow and they were examined the same way as lame sows but received no treatment. Lame sows were more passive, they lay more and stood and explored pen fixtures less than the control sows before treatment. After 5-days treatment, placebo-treated sows were in contact with the wall and lying more often when compared to control sows. Ketoprofen-treated sows were more seldom in contact with the wall and exploring bedding more often than placebo-treated sows. Placebo sows tended also to move and explore bedding less than control sows. Lameness had been relieved in altogether 7 out of 13 sows on day 5: six out of nine ketoprofen-medicated sows and one out of four placebo-treated sows. The behaviour of sows with relieved lameness did not differ from that of control sows on day 5. Sows with non-relieved lameness were in contact with the wall and lying more and moving and standing less than control sows. When compared to control sows, sows with non-relieved lameness tended to be more passive. When compared to sows with relieved lameness, sows with non-relieved lameness showed a tendency to be in contact with the wall more often. Our study showed that lameness reduces the activity of sows and affects their position in the pen. Passive behavior seemed at least partly be due to pain and lameness relief was associated with normalization of the behavior.

    Shoulder lesions are common in lactating sows and can affect their welfare. We assessed the systemic inflammatory response to shoulder ulcers and monitored the preventive effect of postpartum administration with non-steroidal anti-inflammatory medication (ketoprofen) on their prevalence. In a double-blind placebo-controlled field trial, 144 YxL hybrid sows farrowing in crates with a cast-iron floor received either ketoprofen (3 mg/kg) or placebo as an intramuscular injection on days 0-1 after parturition. During the lactation period (weeks 1–4) all sows were assessed weekly for the presence of shoulder ulcers (0 = no ulcer, 1 = unilateral ulcer, 2 = bilateral ulcers; in all cases at least epithelial damage). From a subset of 37 sows, haptoglobin (Hp), albumin (ALB) and cortisol (COR) were measured from blood samples taken 10 to 12 days after farrowing. Results were analyzed according to a linear regression model for associations between Hp, ALB, COR and shoulder ulcers. A random ordered logistic model was used to assess risk factors (body condition score (BCS), back and shoulder fat, decrease in BCS or fat layer thickness during lactation, parity, number of live born and stillborn piglets, piglets weaned, shoulder ulcer scar) and the effect of ketoprofen treatment. Total prevalence of shoulder ulcers at lactation weeks 1–4 was 26.4%, 33.3%, 38.2% and 38.9%, respectively. Prevalences of unilateral shoulder ulcers at lactation weeks 1–4 were 16.7%, 19.4%, 20.8% and 18.8%, and prevalences of bilateral shoulder ulcers were 9.7%, 13.9%, 17.4%, and 20.1%. There was a decrease in albumin and an increase in Hp levels in sows with bilateral shoulder ulcers compared with sows without shoulder ulcers (P
