The Effect of Claw Lesions and Claw Infections on Lameness in Loose Housing of Pregnant Sows
Effekten av klauvskader og klauvinfeksjoner på nätthet hos drektige purker i løsdrift

Abstract
During a 12-month period lameness, claw lesions and claw infections were studied in 15 herds with loose housing of pregnant sows on partly slatted concrete floors. Of these herds, 12 herds had concrete slats and 3 herds had plastic slats. The mean prevalence proportion of lame sows in the herds was 13.1%. The risk of lameness increased with increasing claw lesion score and with the presence of claw infections. In the herds with concrete slats, the relative risk of lame sows was 2.4 times higher than in the herds with plastic slats. In the herds with poor floor hygiene, the relative risk of lameness was 2.8 times higher than in the herds with dry and clean floors. The mean prevalence proportion of sows with claw infections at the 3 separate examinations in the 15 herds was 3.8%. Claw infections were more prevalent in herds with dirty floors and in herds with little space per animal (<2m2). In the herds with concrete slats, the relative risk of claw infections was 2 times higher than in the herds with plastic slats.
Sammendrag
En feltundersøkelse ble i løpet av ett år gjennomført i 15 besetninger med løsgående purker. Alle besetningene hadde betonggulv med spalter på ca. en tredel av arealet. Tolv besetninger hadde betongspalter mens 3 besetninger hadde plastspalter. Den gjennomsnittlige prevalensen av halte purker i besetningene var 13.1% og av purker med klauvinfeksjon 3.8%. Risikoen for hallhet økte med økende klauvskade score og hvis det var infeksjon i klauvskaden. Purker som ble holdt på betongspalter, hadde høyere risiko for å få klauvinfeksjoner og for å bli halte enn purker som gikk på plastspalter. I besetninger med dårlig renhold og lite strø var risikoen for klauvinfeksjoner og halthet størst Det var størst risiko for klauvinfeksjoner i besetninger med lite areal (< 2m2) per purke.
