This article describes the effectiveness of uterotonic, oxytocin, and iodopen drugs in the treatment of infertility caused by placental retention and shortening the service period in productive cows cared for on farms today. Keywords: Cow, placenta, endometritis, involution, diet, oxytocin, yodapen, uteraton, drugs. One of the causes of infertility is diseases of the genital organs, and frequent retention of the placenta can be the cause of postpartum diseases, especially endometritis, which leads to a sharp decrease in productivity, infertility, and early loss of animals. The detention of the latter is one of the most common disorders affecting the reproduction of dairy cattle. World science and practice have achieved certain successes in solving the problem of the detention of the latter in cows. Many aspects of the etiology and pathogenesis of this pathology have been studied, and new methods and means of its treatment and early prevention are developed and implemented. Despite the available achievements, many issues regarding therapy and prevention are not resolved in the problem of detention. A high percentage of complications of this pathology with endometritis remains the outcome of which is a decrease in the productivity and reproductive function of animals, and a decrease in the duration of their economic use. Significant damage in this pathology is caused by the marriage of milk, which is associated with contamination by antibiotics and other chemotherapeutic agents. With the obvious advantages of the operational compartment of the PLO, it can cause damage to the uterine mucosa, complications of this pathology by metrite, and infertility. In this regard, it is necessary to further improve methods and the development of new means for conservative treatment of highly productive dairy cows during the detention of the last. Celebrating the role of a decrease in chemotaxis and phagocytic activity of leukocytes in the pathogenesis of the placenta makes further study of the preventive and therapeutic efficiency of immunomodulators with the predominant influence on the phagocytic link of immunity. The establishment of the relationship between the detention of the past and fetoplacental insufficiency shows the need to study the effectiveness of the preventive use of means that correct the function of the fetoplacental complex. In this regard, the study of environmentally friendly drugs of natural origin containing a complex of biologically active substances, including polyunsaturated fatty acids, is promising. An important task is also to study the main risk factors for the detention of the latter in highly productive cows associated with feeding, and the improvement of methods for their control, which will allow a directed correction of such violations. The foregoing served as the basis for setting the goal and the formation of the tasks of this work. Global Scientific Review A Peer Reviewed, Open Access, International Journal www.scienticreview.com Volume 11, January 2023_____________________________________ ISSN (E): 2795-4951 We observed the calving process of Holstein cows (for 3 years) at the Besh-bola farm in Pastdargom district of Samarkand region. Some of the cows and heifers on this farm are kept in stables with heat and bedding, and in good weather, they are grazed in closed areas - in the playgrounds. The rest of the animals are kept free in non­ removablebeds. Corn silage - 25 kg, alfalfa hay - 4 kg, straw (wheat groats) - 6 kg, and oat groats - 3 kg are included in the ration. Placental retention was observed in 6-7% of the number of young and old cows that were kept permanently connected during the calving period. Cows with retained placenta were treated with uterotone, and oxytocin, and after removing the hanging part of the placenta, an iodopen pill was placed into the uterus. . The animals were taken to the treatment facility. Oxytocin 40-50 ME and 10 ml of Uteraton drug were injected subcutaneously into the neck region 6-8 hours after the delivery of the cow, whose placenta was retained. The uterus was thoroughly washed with Furatcelin solution in a ratio of 1:500, and the hanging part of the placenta was cut and removed. Two iodopen tablets were placed in the uterine cavity after cleaning the hand. On the second day, two Yoda pen tablets were again inserted into the uterine cavity. Then, every 2-3 days, the uterus was massaged through the rectum until it returned to its position. Aqueous disinfectant solutions were not used to wash the uterus during treatment. In 12 treated cows, the placenta was separated naturally, of which 8 cows were separated in 4-5 hours, 4 cows were separated in 6-9 hours, and 5 cows were surgically separated after 48 hours. After natural descent and operative separation of the placenta. During the first 2-3 days, the cow was observed to have purulent blood-mixed liquid discharge from her vagina. In the following days, the color of the secreted liquid started to
