A route of using a foamy aerosol NITAZOL for subclinical mastitis in dry cows has been developed and tested. The therapeutic efficacy of the preparation was estimated by the frequency of administration and in comparison with mastisan-E. For intracisternal administration of nitazol, a rubber tube coupling to a teat tube was put on a standard nozzle attached to a balloon. The administration of nitazol at the dose of 0/1 g or 20 ml of foam twice a day (morning and evening) or once after evening milking has shown the equal therapeutic efficacy but the costs of the preparation for a double administration were 1.8 times more. A comparison of nitazol with mastisan-E has found an inconsiderable difference in their bactericidal activity. So, 24 h after administration of the preparations of nitazol the number of somatic cells in a secretion of mammary gland reduced for nitazol – by 2.2 million/ml (by 26.8%), for mastisan-E – by 2.1 million/ml (by 25.6%, after 48 h – by 30.0% and 31.2%), respectively reaching the physiological standard of the second dry day after 2 days of treatment. The treatment course of cows with nitazol was 3.5 days, with mastisan-E -3.4 days with the number of administrations 0f 2.5 against 4.8, that is, 1.9 times more. It is concluded that being equal to mastisan-E in its efficacy, much less nitazol is required (1.8 times) for a single administration a day after evening milking.
