Role of Bovine Digital Dermatitis (BDD) on service period of dairy cattle

Several conditions of foot infections of cattle ; bovine interdigital dermatitis, bovine interdigital necrobacillosis, bovine digital dermatitis (BDD), lamellar suppuration are described in the literature (5, 6). The bovine digital dermatitis is the most frequent one causing a painful and severe lameness ; economic loss due to decreased milk production and reproduction performance (4, 5, 7). The disease was described for the first time in Italy in 1974 as Mortellaro’ s disease. It occurs primarily in dairy cattle and have been reported as a cause of lameness worldwide, including Albania. BDD is generally considered as infectious disease (4). This study is focused on the role of bovine digital dermatitis on service period of affected cows. The study was carried out on dairy cattle herd in Tirana, Albania. The prevalence of this condition was evaluated, the main bacterial causes were isolated and the time of successful insemination was surveyed. The animals were divided in two groups. Each group consisted of six cows in same physiological status and management conditions. The first group was composed of cows not affected, while the second group comprised the animals affected by foot infections. The prevalence of foot infections on the farm was 18, 67%. The main bacterial agents implicated were Fusobacterium necrophorum, Dicolobacterium nodosus and Arcanobacterium pyogenes. A significant difference between two groups was established. The cows from the first group were successfully inseminated 91, 5  13, 3 days after delivery. The affected group of cows was successfully inseminated 139  143 days after parturition.
