In a large outdoor pig production unit with high prevalence of locomotor pr
oblems 304 sows suffering claw lesions were divided into four experimental
and a control group and were treated during the entire spring summer period
as follows: each experimental group was provided with a plastic foot bath
device of 20 cm depth that the sows had to pass at every time of feeding. G
roup one (62 sows) received a foot bath of 1% formaldehyde solution, group
two (60 sows) a 5% copper sulphate solution, group three (62 sows) an oxyte
tracycline - paraffinoil - pit - mixture mud and group four (60 sows) prese
nted the untreated control having received plain water foot bath. Group 5 (
60 sows) presented the untreated control. The with oxytetracycline - paraff
in - pit - mixture treated animals presented significant less claw lesions
when compared to the other groups.
