Mineral-Vitamin Complexes in Sheep Nutrition: Patent Analysis and Functional Evaluation for Pregnant Ewes and Lambs.
Review in Molecules (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Natural pasture, the primary feed source in sheep production, often provides insufficient levels of essential minerals and vitamins required for proper metabolic regulation during pregnancy and early development. This study aimed to analyze patent developments of mineral and vitamin complexes (MVCs) for pregnant ewes and lambs and to evaluate the biochemical and molecular relevance of their components based on scientific evidence. A search of the World Intellectual Property Organization (WIPO) database using the keywords "vitamins for sheep" and "minerals for sheep" identified 120 patents related to sheep feed additives, including 23 specifically formulated for pregnant ewes and lambs. Comparative analysis revealed that calcium, selenium, iron, copper, cobalt, sodium, manganese, zinc, and vitamins A, D, and E were the most frequently included components. These micronutrients play critical roles in enzymatic activity, regulation of gene expression, antioxidant defense systems, and mineral homeostasis. In particular, zinc and selenium function as structural and catalytic cofactors for antioxidant enzymes such as superoxide dismutase and glutathione peroxidase, while vitamins A and D regulate cellular differentiation and calcium-phosphorus metabolism through transcriptional control mechanisms. Additionally, functional additives, including amino acids and plant-derived bioactive compounds, contribute to improved mineral bioavailability and modulation of metabolic pathways. The analyzed formulations demonstrate a consistent focus on correcting mineral deficiencies, enhancing antioxidant protection, and supporting metabolic adaptation during pregnancy and early postnatal development. Overall, the findings indicate that modern MVCs are rationally formulated to improve mineral utilization, physiological stability, and reproductive outcomes, highlighting their critical role in optimizing maternal health and offspring viability in sheep production systems.
