Microbial analysis of jeevamrutha prepared from different cow breeds of desi and cross cow breeds cow dung and cow urine

A laboratory experiment was conducted on shelf-life of jeevamrutha at Zonal Agricultural and Horticultural Research Station (ZAHRS), Brahmavar, Udupi. In this study three different desi breeds viz., Malnad gidda, Gir, Sahiwal and three different cross breeds viz., Holstein Friesian (HF), Jersey and crossbred Jersey, cow dung and cow urine were collected aseptically and separately to prepare Jeevamrutha, after preparation of Jeevamrutha from 1^st day to 15^th days samples were collected (daily) and enumerated the general microorganisms viz., bacteria, fungi and actinomycetes with their respective media. Among the desi and cross cow breeds jeevamrutha, desi cow breeds jeevamrutha contains higher microbial population compared to cross cow breeds jeevamrutha. In desi cow breeds jeevamrutha, Malnad gidda cow breed jeevamrutha contains the maximum microbial population.  In general, the highest microbial population was noticed between 7^th to 9^th days after preparation (DAP) of jeevamrutha in all the cow breeds. Hence, it’s considered as a best time for the application of jeevamrutha to soil to improve the soil organic carbon.
