Rubber slat covers have been suggested as a solution to these issues.

However, studies to date examining the effect of slats versus mats on the welfare of beef cattle have shown conflicting results, along with variation between mat types.

A recent study conducted at Teagasc Grange investigated the effects of rubber mats on animal performance and hoof health.

Durapak mats and Continental suckler-breed bulls were used in the study. Initial treatment group weights were 441kg and bulls were adapted to a simple finishing diet.

Results

Bulls housed on rubber mats grew faster (160g/day) and had improved feed conversion ratio compared with those housed on concrete slats.

After 148 days, carcases from bulls on mats were 12kg heavier than those on concrete slats – though the result was not scientifically significant in this case.

Floor type had no effect on intake, killout percentage, carcase conformation score or fat score.

Bulls on rubber mats did, however, have 44% more hoof lesions than those on concrete slats – suggesting hoof health may be slightly compromised due to a decreased wear effect on the rubber mats.

The study also found that both animals housed on slats and rubber mats were of similar cleanliness at the time of slaughter.

Crucially, of the 14 haematology (immune response) variables measured, there was no differences attributed to floor type – stress levels were unaffected.
