Background: Antibiotics have been in use in the treatment of bovine mastitis since decades; however, their use is associated with cost issues and human health concern. Use of herbal drugs does not generally carry these disadvantages. Many plants/herbs have been evaluated in the treatment of bovine mastitis with additional property of immunomodulation in affected mammary gland. Aim: To evaluate a topical herbal drug in two breeds of cattle for its in-vivo immunomodulatory effect on cytokines production and antibacterial activity in bovine subclinical mastitis. Materials and Methods: The response to treatment was evaluated by enumerating somatic cell count (SCC), determining total bacterial load, and studying the expression of different cytokines (interleukin [IL]-6, IL-8, IL-12, granulocyte macrophage-colony stimulating factor, interferon (IFN)-γ and tumor necrosis factor [TNF]-α). Results: The pre- and post-treatment SCC in mastitic quarters statistically did not differ significantly, however, total bacterial load declined significantly from day 0 onwards in both the breeds. Highly significant differences (P < 0.01) were observed in all the cytokines on day 0, 5, and 21 postlast treatment in both the breeds. The expression level of all the cytokines showed a significant increase on day 5, while a decrease was noticed on day 21 in both the breeds of cattle. The comparison of cytokine expression profiles between crossbred and Gir cattle revealed a significant difference in expression of IL-6 and TNF-α. However, other cytokines exhibited a similar pattern of expression in both breeds, which was non-significant. Conclusion: The topical herbal drug exhibited antibacterial and immunomodulatory activities in subclinical mastitis and thus the work supports its use as alternative herbal therapy against subclinical udder infection in bovines.
