Effectiveness of treatment of cow`s metritis using forest industry complex products

The article presents the results of a scientific and economic experiment conducted in 2022 under the conditions of one of the leading farms in the Vologda Region on black-and-white cows with the milk productivity of about 9,000 kg per lactation. The subject of the research has been a preparation based on products of the forest industry complex with a predominance of pine tar and pine needles composition. According to the main active substances, this remedy has antiseptic, anti-inflammatory, stimulating and regenerating properties. The studies have been carried out by the method of analog groups. Two groups of cows have been formed: an experimental group and a control one, with 10 heads in each, the groups have had comparable indicators of live weight, number of lactations, and milk productivity for previous lactations. Cows of the control group have been treated according to the scheme indicated on the farm. Animals of the experimental group have been treated with the replacement of some drugs with a new tested phytoncidal agent. Such indicators as the number of days of treatment, service period, insemination index, hematological and immunological blood parameters, quantity and quality of milk have been controlled and compared. According to the days of treatment, service period and insemination index, the cows of the experimental group were in an advantageous position, namely: 90% of the cows of the experimental group were cured on day 10, while in the control group there were 80%. The service period has been shorter by 3 days. The insemination index has been lower by 0.2. The economic efficiency of treatment has also been higher in experimental animals, namely: the cost of treating one head has been 703 rubles. In the control group it has been 1,341 rubles. According to the indicators of blood and milk in animals of the experimental and control groups, identity has been noted. A new phytoncidal agent for the treatment of metria in cows has been proposed to farms for use according to a certain scheme.
