The Effectiveness of Herbal Antibacterial Formulations Against Mastitis-Causing Bacteria in Dairy Cattle

This study aimed to determine the effectiveness of antibacterial formulations derived from herbal plants against mastitis-causing bacteria in dairy cattle. Herbal extracts composed of betel leaves extract, kecombrang flower extract, and turmeric extract were tested against Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli. The research was carried out ina Completely Randomized Design (CRD) using ten treatments and four replications at the Laboratory of Research and Testing, Faculty of Animal Husbandry, Padjadjaran University. The results showed that herbal antibacterial formulations could inhibit the growth of Staphylococcus aureus, Streptococcus agalactiae, and Escherichia coli bacteria. The most inhibitory power was obtained from P8 treatment (50% betel leaves + 50% kecombrang flower + 50% turmeric) categorized in "strong inhibition." The percentage of antibacterial inhibition of P8 formulation compared to chloramphenicol was 32% against Staphylococcus aureus, 33% against Streptococcus agalactiae, and 31% against Escherichia coli. Conclusively, the best herbal antibacterial formulation was a combination of 50% betel leaves extract, 50% kecombrang flower extract, and 50% turmeric extract
