Effects of Urea-Molasses Multi-nutrient Blocks (UMMB) supplementation on some production parameters of lactating Horro cows at Horro Guduru Animal Production and Research Center, western Ethiopia

Abstract

An emerging of antibiotic resistance brings most serious public health problems. It is therefore, important to look for more effective, safer and less toxic alternate options of treatment. The aim of the present study was to investigate antibacterial activity of Moringa stenopetala against some human pathogenic bacteria using disk diffusion method and agar dilution for minimum inhibitory concentration. The result revealed that, most of the plant extracts had antibacterial activity. Staphylococcus aureus was found to be the most susceptible bacteria to crude 80% methanol extract of seeds and ethyl acetate extract of susceptible bacteria to crude 80% methanol extract of seeds and ethyl acetate extract of root barks with inhibition zones of 18.66±0.88mm and 16.00±1.15mm and minimum root barks with inhibition zones of 18.66±0.88mm and 16.00±1.15mm and minimum inhibitory concentration of 1.25mg/ml and 2.5mg/ml respectively, whereas Pseudomonas inhibitory concentration of 1.25mg/ml and 2.5mg/ml respectively, wh aeruginosa was was the most resistant bacteria to all of crude extracts. Similarly, the most resistant bacteria to all of crude extracts. Similarly, Staphylococcus aureus was the most susceptible bacterial strain to chloroform fraction with was the most susceptible bacterial strain to chloroform fraction with inhibition diameter of 28.00±0.57mm and minimum inhibitory concentration of 0.31mg/ml, inhibition diameter of 28.00±0.57mm and minimum inhibitory concent while Pseudomonas aeruginosa was the most was the most resistant strain with inhibition zone of resistant strain with inhibition zone of 9.66±0.33mm and minimum inhibitory concentration of10mg/ml respectively. In conclusion, 9.66±0.33mm and minimum inhibitory concentration of10mg/ml respectively. In conclusion, this study is not only proves antibacterial activity of Moringa stenopetala, also provides a this study is not only proves antibacterial activity of scientific basis for their traditional use. Pure chemical compounds and antimicrobial activity scientific basis for their traditional use. Pure chemical compounds and antimicrobial activity against many fungi and bacteria should be studied to use them as sources and templates against many fungi and bacteria should be studied to use them as sources and templates for synthesis of drugs to control infectious diseases.
