Abstract
Background: Internationally, foot trimming is used by most farmers and parenteral antibacterials by some, to treat sheep with footrot. Non steroidal anti-inflammatory drugs (NSAID) are sometimes used. No clinical trials have compared these treatments.
Objectives: To investigate the above treatments on time to recovery from lameness and foot 5 lesions in sheep with footrot.
Animals: 53 sheep with footrot on a commercial farm in England.
Methods: In a randomised factorial design, the sheep were allocated to treatment groups. The 8 treatments were oxytetracycline spray to all sheep (positive control) and one or more of: parenteral administration of long acting oxytetracycline, flunixine meglumine and foot trimming on day 1 or day 6 of diagnosis. Follow-up was for 15 days. Time to recovery from lameness and lesions was investigated with discrete- time survival models.
Results: There was significant association (p<0.05) between recovery from lameness and lesions. Sheep receiving antibacterials parenterally recovered faster from lameness (odds ratio (OR): 4.92 (1.20-20.10)) and lesions (OR: 5.11 (1.16-22.4)) than positive controls whereas sheep foot trimmed on day 1 (lameness- OR: 0.05 (0.005-0.51); lesions- OR: 0.06 (0.008-0.45)) or day 6 of diagnosis (lameness-OR: 0.07 (0.01-0.72); lesions- OR: 0.07 (0.01-0.56)) recovered slowly than positive controls. NSAID had no significant effect on recovery.
Conclusions and Clinical Importance: If foot trimming on day 1 or 6 of diagnosis was stopped and parenteral antibacterials were used, then over 1 million sheep/annum lame with footrot in the UK, would recover more rapidly with benefits to productivity. Globally, this figure would be 21 much higher.
