Sažetak
The research was carried out in order to establish the efficiency of ecologically acceptable disinfectants in milking hygiene to prevent postsecretion milk contamination by unclean teats. The research included 15 cows from the same breeding lot teats were disinfected with the agents obtained by electrochemical activation technology which show strong oxide-reduction potential and cause damage in all main groups of microorganisms and are not harmful to man and other higer organisms. Teats were treated just before milking following the producers (Aquastel, Croatia) instructions. They were washed in a water solution of sodium chloride, sodium hypochlorite and sodium hydroxide and then immersed into a water solution of sodium chloride, hypochorus acid and hypochlorite ion. Samples of swabs were taken from the surface of the teats in the condition found prior to preparing the animal for milking, after washing the teats and immersing them into disinfectant. According to the results obtained there was a significant decrease in the total number of aerobic mesophyll bacteria (p< 0, 05) on the teats surface after antiseptic treatment had been applied. After washing the teats the number of bacteria decreased by 89, 5 % and after immersing the teats into the disinfectant by 98, 1 % with respect to the number of bacteria found before the teats were prepared for milking. On the ground of the results obtained the tested agents can be recommended for successful reduction in the number of bacteria on teats vecause together with preventing postsecretion contamination they can reduce the risk of bacteria invading through teat canals the milk gland.
