Jerzy Molenda, Jan Twardoń, Małgorzata Błaszkowska, Małgorzata Czerw
The purpose of the study was determination of microbiological contamination of dairy farms with a special regard of pathogenic bacteria, the causal agent of udder infection. Studies were carried out in two farms with various systems of maintenance and milking. Moreover, occurrence of different clinical form of mastitis in dairy cows and their causative agents were analysed. In the air of cow shed a lot of microorganisms were found, but without main udder pathogens, responsible for mammary gland in those farms. However, these pathogenic bacteria were many times isolated from dairy equipment /milking machines and containers/. The equipment then can be source of the pathogen and mediatory factor of its dissimination.
Key words: microbiological monitoring of dairy farm environment, mastitis examination, udder pathogens, collected milk quality.
