The study aimed to investigate the effects of teat disinfection (dipping treatment) after milking on hygienic quality of row milk. The research was conducted on the farm with 30 Holstein-Friesian dairy cows. Animals were kept in a tied housing system. Milking is done by a bucket milking units using vacuum line. The research was carried out during the period of 2 months from 26.11.2012 till 25.01.2013. Results showed that milk immediately after leaving the udder was minimally contaminated with microorganisms (average of both groups with 8,933 CFU/ml). Experimental group had an average 2.668 (133,000 SCC/ml) and control group 3.524 (about 257,000 SCC/ml) (p<0.05). The average value of CFU in experimental group was 5,816 (729,000 CFU/ml) and in the control 5.833 (805,000 CFU/ml), (p<0.05). During the study period, the average value of SCC in the experimental group decreased to 2.67 (133.020/ml) and the average value of CFU to 5.82 (729.064/ml), (p<0.05). Treatment of teat dipping after milking is justifiable and has positive impact on row milk quality.
