Efecto de ozonoterapia sobre las afecciones uterinas en vacas repetidoras

Abstract

The research was carried out at “Nero” and “Irquis” farms of the University of Cuenca and the private farm “El Carmen” in the Azuay province; the objective of the study was to evaluate the effect of ozone therapy on subclinical endometritis in repeat breeder cows (RBC), for this study a total of 42 RBC with subclinical endometritis (SE), multiparous with a body condition of 2.5 - 3; the diagnosis of SE was made by endometrial cytology considering positive those that present a percentage ≥ 5% of polymorphonuclear cells (PMN), in addition the diameter of uterine lumen in millimeters (mm) at the base of one of the uterine horns was evaluated by ultrasonography; subsequently, samples of uterine secretion were collected for the identification of bacterial agents; to then perform the intrauterine treatments, for G1 (n = 21) 500 mg of cephapirin benzathine was applied and G2 (n = 21) 45 ug of O3 was used in 50 ml of sterile bidistilled water; after 72 hours the effect of treatments was evaluated. The results were analyzed by basic statisticians, logistic regression and contingency tables, using INFOSTAT. The prevalence of SE in RBC during the study was 47.76%; in the G1 the PMNs decreased from 12.5 ± 0.99 to 6.5 ± 0.76% and for the G2 they showed a greater therapeutic effect 11.5 ± 1.19 to 4.0 ± 0.52%; the diameter of the uterine lumen was reduced in G1 from 2.23 ± 0.14 to 1.72 ± 0.08 and in G2 from 2.21 ± 0.12 to 1.62 ± 0.13 mm not differ between them; in relation to the presence of bacterial agents, 45.24% Staphylococcus spp., 9.5% Escherichia Coli, 7.4% Pseudomonas Spp., 9.5% Bacillus spp., and 38% of the samples did not show isolation bacterial; the percentage of pregnancy reached was 33.0% in G1 and 48.0% for G2 they did not express differences (P> 0.05) but manages to recover fertility. In conclusion, intrauterine administration of benzathine cefapirin and ozone reduces the diameter of the uterine lumen; however, ozone proved to be better in PMN reduction than allopathic treatment (benzathine cefapirin).
