Experimental data from stock-health registers and history sheets of animals maintained at the institute for a period of 12 years (2000-2011) was used for this study. A total of 1078 lactation records comprising Karan Fries (943 KF) and Karan Swiss cows (135 KS) cows were classified according to parity viz., I, II, III, IV, V, VI & above. The average days under treatment were maximum in Ist parity (14.28) and minimum in 3rd parity (8.63). The total treatment cost was more (P<0.05) in 4th parity (Rs.470.52) and less in 2nd parity (Rs.250.00). The fibrosis rate of the quarter was maximum in 5th parity resulting in higher loss of animal value. The parity wise result indicated highest loss in milk yield/day and the production loss in third parity (5.40kg and Rs. 1020.24) than in first parity (4.45 kg and Rs.754.80).The loss of milk yield/day, duration of mastitis in days, production loss, average days under treatment, total cost of treatment and average number of quarter affected/mastitis infected cow were higher (P<0.01) in the year 2011 and lower in 2003. The grand total loss /cow was highest in the year 2011 (Rs. 3763.81) and lowest in 2001 (802.63). Grand total loss /cow was maximum with a THI score of 73-78 which was similar for the THI score <72 or 79-89. The overall actual loss of milk yield/day (kg) of mastitis infected cows was higher (P<0.01) in KF followed by SW, TP and KS cows. The various parameters of economic losses during different years was significant (P<0.01) in different breeds except for average number of quarter affected per mastitis infected animal. However, there was no effect of season on mastitis infection.
