Abstract: The aim of this blind and longitudinal farm study was to evaluate the efficacy of Provita Hoofsure Endurance (PHE) foot wash solutions in reducing the prevalence rate of lameness due to Papillomatous Digital Dermatitis (PDD) in dairy cows. The 182 cows from three commercial dairy herds were diagnosed with lesions of PDD in different stage of development by lameness score and pain scoring. The prevalence rate of lameness was calculated between 28.8 and 43.6% on the basis of locomotion scoring system (1-5). The cows were considered for individual evaluation under significant of Kappa value and restrained in a chute for lesion type (0-4), color (0-2) and size (0-2) scoring prior to application of PHE in walk through footbaths or group topical spray in milking parlor and at the end of trials. The cows were allocated to one of two groups: cows in group 1 were treated with PHE 2.0% twice a day for 3 consecutive days in footbath and treatment repeated again after 2 weeks with PHE 1.0% twice a day for 3 consecutive days in group 2, solution 2.0% were sprayed on palmar surface of the feet. Changes in each score between initial and final scoring were calculated and the comparison was made statistically using non-parametric U-test with 0.05 level of significance. From the results of this farm study, it is concluded that the application of PHE alleviates lameness significantly at the herd or the cow-level when control program of PDD is monitored.
