Abstract
In this study, we evaluated the effect of treated and auto-recovered clinical endometritis on fertility as a uterine disease class. We collected data on breeding, diseases, and cyclicity. Regarding the co-affections, cows with auto-recovered clinical endometritis were affected in groups 1 and 2. Cows with treated clinical endometritis represented groups 3 and 4, and cows without clinical endometritis represented Groups 5 and 6. Once the cyclicity recovered, cows were inseminated. Studied fertility parameters were; 1: conception rate; 2: days to first insemination; 3: success rate in the first insemination; 4: days to conception; and 5: days between first insemination and pregnancy. We performed ANOVA-analysis, Chi-square test, and Machine Learning K-means. A significant difference was noted for days to first insemination (p-value = 0.05), reinforced by a Fisher-LSD post-hoc analysis test that demonstrated significant differences between groups (3 and 5), p-value = 0,006, groups (3 and 1), p-value = 0,019, and groups (3 and 6), p-value = 0,005. However, the conception rate was significantly higher in the groups with non-treated clinical endometritis (p-value = 0.030). Concerning the other parameters, we did not notice significant differences among groups. Our results showed that auto-recovered cows from clinical endometritis had better fertility outcomes.
