EFFECTIVENESS OF NOVOCAINE BLOCKADE APPLICATION ACCORDING TO I.P. LIPOVTSEV FOR TREATMENT OF COWS WITH SUBCLINICAL ENDOMETRITIS

Abstract

The aim of the study is to investigate the effectiveness of using the middle uterine artery puncture according to I.P. Lipovtsev with the introduction of 0.5 % novocaine solution in combination with the antibio¬tic-containing drug Ceftonit Forte in cows with subclinical endometritis. Objectives: to study the therapeutic effectiveness of the introduction of 0.5 % novocaine solution in combination with the antibiotic-containing drug Ceftonit Forte into the middle uterine artery at different times of the estrous cycle; to establish the fertilization rate of cows after the combined use of novocaine blockade according to I.P. Lipovtsev and the drug Ceftonit Forte at different times of the estrous cycle. The object of the study were cows of the red-motley breed with a subclinical form of endometritis. The diagnosis of subclinical endometritis was made according to the method of N.A. Flegmatov. Laboratory studies have established the presence of subclinical endometritis in 29.24–38.21 % of infertile cows. In 16.98–21.69 % of cases, the cervicovaginal mucus did not have visible threadlike or point inclusions of purulent exudate, but the reaction of such mucus with sperm was positive. Therefore, the absence of purulent exudate inclusions in the cervicovaginal mucus cannot indicate the absence of subclinical endometritis in cows. It has been established that a single use of novocaine blockade according to I.P. Lipovtsev in combination with the antibiotic-containing drug Ceftonit Forte of domestic production, regardless of the timing of administration during the estrous cycle, ensures recovery of 95.24–100 % of cows, and the fertilization rate after artificial insemination of females is 76.19–80.95 %. In addition, there is no need to wait for the onset of estrus in cows with subclinical endometritis to administer drugs into the cervical canal, as is generally accepted in veterinary practice, which allows for more rapid treatment of animals with this uterine pathology and significantly reduces the number of days of infertility.
