摘要

Background

Calf diarrhea represents a prevalent and serious challenge in dairy farming. While medicinal plants demonstrate considerable potential for preventing calf diarrhea within antibiotic-free farming systems, their active components and mechanisms remain poorly characterized. The objective of this study was to investigate a polyherbal mixture (PM; including Crataegus pinnatifida, Callicarpa nudiflora Hook. & Arn., Mallotus apelta (Lour.) Müll.Arg., Amomum villosum Lour., Centella asiatica (L.) Urban, and Alpinia oxyphylla Miq.) supplemented to preweaning calves from d 4 to 60, utilizing an integrated approach combining network pharmacology, metabolomics, and microbiomics.

Results

Dietary supplementation with 40 g/d of PM significantly decreased the occurrence of diarrhea (P < 0.05), increased monocyte levels (P < 0.05), and improved jejunal villus height (P < 0.05). Network pharmacology predicts that IL6, EGFR, SRC, TP53, and CCND1 are key targets, while acacetin, chrysin, tectochrysin, dihydroartemisinic acid, and lysionotin may be potential active constituents. The serum metabolome revealed that PM supplementation significantly enriched the steroid hormone biosynthesis. At the same time, PM altered the gastrointestinal microbiota, increasing the abundance of bacteria such as Mediterranea massiliensis, Prevotella denticola, and Duncaniella freteri in the rumen and Clostridium nexile in feces, while decreasing the abundance of Blautia producta, Vescimonas fastidiosa, and Alistipes putredinis in feces (P < 0.05).

Conclusions

Collectively, these findings suggest that PM supplementation alleviated calf diarrhea by remodeling serum steroid hormone biosynthesis and improving ruminal and fecal microbiota composition. Acacetin, chrysin, tectochrysin, dihydroartemisinic acid, and lysionotin may be potential active components.
