EFFICIENCY OF APPLICATION OF THE PREPARATION ON THE BASIS OF IODINE FOR MASTITIS IN COWS

Abstract

The article presents the results of establishing the effectiveness of the use of an experimental preparation based on iodine for various forms of cow mastitis in a farm for the production of commercial milk. Inflammation of the mammary gland is the most common condition in productive herds of cows. Subclinical mastitis, which does not manifest with typical clinical signs for this pathology, is a particular health hazard, but qualitative changes in milk are determined by laboratory tests. Also huge economic losses on farms are recorded during the diagnosis of clinical forms of mastitis in the livestock, which often lead to premature culling of cows, a decrease in the quantity and quality of milk received from them. A set of measures for the diagnosis, treatment and prevention of mastitis also requires constant expenditure of funds. The work was carried out during 2020 in a farm that specializes in the production of commercial milk. The experimental drug under study contains iodine as the main active ingredient, which has a pronounced bactericidal and bacteriostatic effect against a wide range of microorganisms - causative agents of mastitis. It also has a general stimulating effect on the immune system of the udder. As synergistic components, the experimental drug contains compounds with pronounced analgesic, decongestant and astringent effects at the site of the development of the pathological process. At the first stage of the research, the influence of the experimental drug on the qualitative characteristics of milk was determined.
 The number of somatic cells was determined in milk after application of the experimental agent after 24, 48, 72 hours and 7 days. At the second stage of the research, we compared the effectiveness of various methods for diagnosing subclinical mastitis in cows during the dry period.
 When we analyzed the data obtained on the effect of the investigated experimental drug based on iodine on the number of somatic cells in the milk of cows with subclinical and clinical (catarrhal and purulent-catarrhal) forms of mastitis, we established a positive dynamics of their gradual decrease. This indicator reached the maximum level of decrease on the seventh day after application of the drug, both in subclinical and in clinical forms (catarrhal and purulent-catarrhal) mastitis, which amounted to 298.6 ± 11.6; 308.6 ± 14.4 and 328.6 ± 34.4 th./ml. The introduction of a drug with a similar compositional composition for the main active ingredients, it was not possible to achieve a similar effect on the dynamics of the reduction of somatic cells.
