The Effect of Enrofloxavetferon and Gentabiferon-B on Blood Parameters of Cows in the Treatment of Endometritis

Impaired fertility in cattle is the cause of economic losses in livestock farms. Complex treatment of cows with acute endometritis may include various approaches, including the use of antibiotics and interferon-based drugs. The therapeutic approach associated with the use of immunostimulating substances is the safest. The aim of the study was to evaluate the blood parameters of cows during the treatment of acute postpartum catarrhal endometritis using «Enrofloxacinferon-B» and «GentabiferonB». It was found that therapy with «Enrofloxacinferon-B», «Gentabiferon-B», and the traditional treatment regimen led to an increase in phagocytic activity, which was probably due to the activation of the immune system of animals. At the same time, during therapy with «Enrofloxacinferon-B», a decrease in catalase activity was observed, which may be due to a decrease in the level of active oxygen forms in the blood of animals during therapy with this drug. It was also noted that during the therapy with «Enrofloxacinferon-B» no changes in the level of the circulating immune complexes were observed, while with the traditional treatment regimen an increase in this indicator was observed. Therapy with «Enrofloxacinferon-B» did not lead to an increase in neutrophils. At the same time, both the traditional treatment regimen and therapy with «Gentabiferon-B» led to an increase in the proportion of neutrophils. It is noteworthy that there was no pronounced negative effect on blood parameters of all three endometritis treatment options. It can be assumed that the most optimal treatment regimen for acute postpartum catarrhal endometritis in cows may be therapy including «Enrofloxacinferon-B» at a dose of 20 ml at intervals of 24 hours for 5 days.
