Abstract

Objective To investigate the effect on ovine footrot of repeated daily footbathing in a solution of zinc sulphate with surfactant. Design Merino sheep were allocated to control and treatment groups of 119 sheep each at week 0. The sheep had a history of S1, U1,T and/or U6 types of Dichelobacter nodosus in interdigital and underrunning footrot lesions. Feet were not pared prior to treatment. Procedure Treatment sheep were footbathed in a 15 to 18% (w/v) solution ofzinc sulphate with surfactant for 10 min on five consecutive days during week 1. At week 2, and fortnightly to week 52, all feet were inspected, lesion scores were recorded and samples were taken for laboratory tests. At week 53, all feet with no lesions at week 52, but with underrunning lesions prior to week 1, were pared and samples were taken. Results After footbathing, there were no lesions in any treatment sheep atany inspection to week 52. The percentage of feet of control sheep with lesions increased from 9% (391 of 4284) between weeks 20 and 36, to 14% (593 of 4284) between weeks 36 and 52. Ninety-five of 96 control sheep with no lesions at week 20 were still asymptomatic at week 52. D nodosus was not isolated from samples taken from 99 and 87 pared feet of treatment and controlsheep, respectively. Conclusion Repeated daily footbathing combined with prolonged exposure to a dry environment eradicated footrot in sheep with both interdigital and underrunning lesions in feet that were not pared prior to treatment.
