Abstract

The use of antibiotics in treating cow metritis leaved antibiotic residues and enhanced antibiotic resistance of bacteria. The use of herb medicines replacing antibiotics in treating cow metritis is recognized as a safer solution, however the herb medicines have some disadvatages,
such as lower treatment efficacy, resulting in lower recovery percentage and longer treatment time. In the recent years, many modern harmaceutical technologies have been studied successfuly, such as application of nano technology have been fastly developed. The use of
nano technology in producing herb medicines demonstrated to enhance the pharmacological effects of the medicinal plants. In this study, we investigated the effect of combining silver nano with extracts from Lactuca indica L., for inhibiting bacteria caused cow metritis. The studied
results showed that additioning 25 ppm silver nano in to the extracts of Lactuca indica L. induced the synergism in enhancing significantly inhibitory effects on bacteria.
