The purpose of the research was to analyze the results of a change in service period, yaliiness and reduction of losses using the new protocol for the prevention of gynecological diseases, as well as the mathematical calculation of the forecast of changes in the coefficient of life-lifetime reproduction of cows.Materials and methods. The work was performed on 215 cows of the Holstetskaya breed of Leningrad type. To prevent the occurrence of gynecological diseases and the afternoon complications, we have been tested by the previously developed preparation of the new generation "Aldecosptimol". It is a preparation of a wide range of action, not a hormonal agent and non-antibiotic groups. As part of the conducted studies, it was found that the minimum bactericidal concentration of the drug is 0.001% of the working solution, which makes it possible to use it on the mucous membranes of the organism of animals and develop on its basis a new protocol for the prevention and correction of various deviations that increase the effectiveness of the insemination and the level of reproduction. Considering the activity of the drug Aldecosptimol and its bactericidal action, we investigated the possibility of its use to prevent postpartum gynecological complications. The following drugs were included in the composition: aldisseptimol, non-α-f2, nitamin. As a control, the drug was used non-aoxyl, well-proven himself for everyday work in veterinary practice. Studies were conducted within 4 months at the first switches of the Holstein breed.Results. The Aldecosptimol preparation in the new protocol has positively influenced the process of subbatencation, the active restoration of the epithelial fabric of the uterine structure and the proliferative process in the uterus, reduced the arrival time in the first hunt and increased the effectiveness of artificial insemination. Thus, the use of a new protocol for the prevention of gynecological diseases made it possible to reduce the service period from 179.9 days (control) to 102.3 days (experience). Calculation of the effectiveness of the application of the new protocol revealed an increase in reproduction by 7.2% (chicks) or 14.4% to exit calves.
