The somatic cell count in the mixed milk of the 4 quarters has dropped from 1.155 million to 200 thousand within 120 hours of the last treatment. In cow 5390 somatic cell count tends to decrease after 48 hours of treatment and this can be interpreted as a success of treatment. However, 72 hours after treatment, the somatic cell count increases again, in the affected quarter causing an increase in the somatic cell count in the mixed milk of the 4 breast quarters from 565 thousand to 812 thousand somatic cells. The amount of residue excreted via milk as a percentage of the total amount applied was from 5.2% to 45.3%. In the group of cows milked 1.5 times a day, the percentage of residue excreted via milk was 17.75% compared to 27.51% in the group of cows with two milkings per day. The average milk yield of the group of cows milked twice a day was 23.55 ± 4.8 kg standard deviation and in the group of cows milked 1.5 times a day was 26.4 ± 2.59 kg.
