Preliminary results of the use of bacteriocins in pre- and postdipping products for dairy cows

Abstract

The aim of this study was testing a bacteriocin product for udder disinfection during milking. The herd was divided in two groups: treatment (T) and control (C). Sterile milk was collected from every single quarter during 3 months. At each sampling, an operator evaluated animal hygiene and teat apex conditions. The results of cyto-bacteriological analyses showed similar bacterial frequencies as well as somatic cells counts in the two groups, despite of the poor hygiene conditions of the herd. Therefore, given the results, the tested product resulted comparable to the conventional one to ensure udder health. Further studies are needed to confirm these results.
