“…Among the set of monitored pigs, the majority was fattened on fully or partially slatted floors. A negative effect of slatted floors on the welfare Jorgensen (2003) and KilBride et al (2008). In our study, this effect has also been demonstrated by higher mortality of pigs transported after fattening to the slaughter house from slatted floor housing compared to pigs transported from solid floor housing.…”

The study monitored the effect of the housing system and the number of animals transported together on transport-induced mortality of slaughter pigs in the Czech Republic in the period from 2004 to 2008. Concerning the type of housing during the fattening, the lowest mortality rate during the subsequent transport to slaughter houses was detected among pigs fattened on solid floor (0.047%) and on deep bedding (0.084%). The highest mortality during transport was detected among pigs fattened on fully or partially slatted floor (0.139%), a significant difference (p < 0.01) was found compared to other housing types. Assessment of the influence of individual pig load size on mortality showed the lowest mortality among pigs transported in loads of up to 40 animals (0.053%). Mortality during the transport in loads of the size of 41 to 120 animals was 0.130%, and for loads of the size over 120 pigs the mortality rate was 0.156%. These mortality rates are significantly higher (p < 0.01) compared to the load sizes of up to 40 animals.

“…Lying on hard surfaces causes swellings and wounds on the limbs of the sows (Mouttotou et al, 1998;Rushen et al, 2007;Gillman et al, 2008;KilBride et al, 2008;von Wachenfeit et al, 2008). The fact that sows housed on rubber slat mats were at reduced risk of scores greater than the median for swellings on the limbs during both parities reflects the cushioning properties of the rubber floor.…”

This study evaluated the influence of floor type on sow welfare with particular focus on lameness, claw lesions (CL), and injuries. The study used 164 gilts housed in groups of 8 from AI to 110 d of pregnancy in pens with concrete (n = 84) slatted floor left uncovered or covered by 10-mm rubber slat mats (n = 80) through 2 parities. Lameness (0 = normal to 5 = severe), limb (0 = normal to 6 = severe) and body (0 = normal to 5 = severe) lesions, and manure on the body (MOB; score 0 to 2) were recorded at AI, 24 to 72 h postmixing, between 50 and 70 d of pregnancy, and 2 wk before farrowing. Claw lesions (score 0 = normal to 3 = severe) were recorded at AI and between 50 and 70 d of pregnancy. The dirtiness and wetness of the floors was scored weekly (score 0 = clean to 4 = >75% of the pen soiled/wet). Data from the first and second parities were analyzed separately. Sows were categorized as nonlame (score ≤ 1) or lame (score ≥ 2). Median (M(e)) scores were calculated for CL and body and limb lesions and were classified as less than or equal to the median or greater than the median lesion scores. Sows on rubber slat mats had a reduced risk of lameness during both parities (P < 0.01) compared with sows on concrete. They also had an increased risk of scores greater than the median for toe overgrowth (M(e) = 2 and M(e) = 3 in the first and second parity, respectively) and heel sole crack (HSC; M(e) = 3) during both parities (P < 0.01) and for cracks in the wall (CW; M(e) = 4) and white line damage (WL; M(e) = 4; P < 0.01) in the first and second parity, respectively. There was a reduced risk of lameness in sows with scores greater than the median for HSC (P = 0.05) in the first parity and WL (M(e) = 3; P < 0.01) and CW (M(e) = 3; P < 0.05) in the second parity. Wounds (M(e) = 3) and severe lesions (M(e) = 0) on the limbs with scores greater than the median were associated with an increased risk of lameness (P < 0.01) in the first and second parity, respectively. Sows on rubber slat mats had a reduced risk of scores greater than the median for swellings (M(e) = 4) and wounds (P < 0.01) during both parities. Pens with rubber slat mats were dirtier than uncovered pens (P < 0.01); however, there was no association between MOB and flooring type. There was also no association between body lesion score and flooring type. In this study, CL were not associated with an increased risk of lameness. Therefore, even though rubber slat mats were associated with an increased risk of CL, they improved the welfare of group housed sows by reducing the risk of lameness and limb lesions.

“…The exceptions were calluses and capped hock where, because of the high prevalence of calluses and the very mild nature of capped hock score one [14], diseased sows were classified as those with a lesion score of two or three.…”

Abstract: and in factors associated with locomotion (slipping and slip marks). These results indicate that the aetiology of capped hock and bursitis might differ.
