Reproductive disorders in Simmental cattle: Enhancing fertility through a hormonal protocol.
Article in Open veterinary journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Reproductive disorders, including abortion, endometritis, and silent estrus, present significant challenges to fertility and productivity in semi-intensive farming systems. These conditions disrupt physiological and hormonal functions, leading to impaired reproductive outcomes. Aim: This study aimed to evaluate the effectiveness of hormonal protocols in addressing these disorders by assessing reproductive tract size, cervical mucus characteristics, and fertility outcomes in cattle with varying reproductive health statuses. Methods: Healthy cattle exhibited optimal reproductive performance and were characterized by high-quality cervical mucus, normal uterine horn dimensions, and superior fertility outcomes. This finding highlights the importance of balanced endocrine function in supporting optimal reproductive efficiency. Results: In contrast, cattle with abortion disorders and endometritis experienced disrupted uterine health, enlarged uterine horns, and diminished cervical mucus quality, resulting in significantly reduced fertility. Silent estrus showed intermediate results, reflecting suboptimal estrus expression and hormonal imbalances that affected reproductive efficiency despite hormonal interventions. Strong positive correlations were observed between cervical mucus characteristics, such as viscosity, acidity, and ferning patterns, and fertility outcomes, indicating their critical role in facilitating sperm survival, motility, and fertilization. Conversely, uterine horn dimensions exhibited a negative correlation with fertility, reflecting the impact of chronic inflammation and structural abnormalities on reproductive success. Conclusion: Although hormonal protocols were effective in synchronizing estrus and inducing ovulation, their efficacy varied depending on the severity of reproductive disorders and environmental management practices. These findings demonstrate that hormonal protocols can partially mitigate the physiological disruptions caused by reproductive disorders; however, integrated reproductive management strategies are essential. Combining hormonal interventions with targeted nutritional support, improved environmental management, and enhanced estrus detection practices is critical for optimizing reproductive performance. This study provides a framework for addressing reproductive challenges in Simmental cattle, supporting sustainable livestock production in semi-intensive systems in resource-limited settings.
