Abstract: Goats’ milk is an attractive product for producers and consumers, because of its health benefits and chemical composition. But there arestill no strict regulations according to specific hygienic rules for this milk safety. Somatic cells number, which is the basic parameter for bovine milk (SCC) vary in goats and it is affected by many factors, e.g. age, estrous phase, type of milking, but also by infectious factors. In our experiment we had analyzed the potential influence of CAEV infection on dairy goats productivity and milk SCC. The experiment was conducted on 24 individuals (12 seropositive/12 seronegative) , with milk samples analysis during subsequent lactations (from 2nd to 5th). The results have shown the impact of viral infection on early and late lactations, with decreased milk yield & increased number of somatic cells in milk. We conclude that it could be correlated with infection progression and the efficiency of goats’ immune system.
