Katsoulos PD, Christodoulopoulos G., Digital dermatitis in a dairy cow, Onl J Vet Res., 27 (9): 503-507, 2023. A primiparous Holstein dairy cow presented with reluctance to bear weight on her right hind-limb asymmetrically swollen at inner digit. After washing and trimming of foot we observed a linear proliferative-type lesion from skin of posterior inner digit of the right hind-limb above heel bulb penetrating hoof of sole in front of heel bulb. The lesion was intensively painful at touch near sole with haemorrhage. Bacteriological examination of skin biopsy revealed Trepanoma spp. but this does not differentiate digital from interdigital dermatitis. For treatment, a wooden block was placed on claw and oxytetracyclin spray and cow injected daily 2.2mg/kg ceftiofur for 7 days. By 2 weeks, animal had normal locomotion and lesions disappeared.
Key-words: Dairy cow, hoof, lesion, Trepanomaa.
