    Major Research Accomplishments:

    • An Alternative Diagnostic Approach was developed for Early Pregnancy Detection in Dairy cattle based on differential Expression of Interferon Stimulated Genes in Blood leukocytes
    • Developed PCR assays for diagnosis of genetic diseases BLAD and CVM in cattle
    • Developed colour based assay for differentiating cow and goat milk.
    • Contributed in the development and evaluation of “Frieswal cattle”, one of the superior crossbred dairy cattle having 5/8 Holstein Friesian and 3/8 Sahiwal inheritance, by ICAR-Central Institute for Research on Cattle, Meerut, in collaboration with Ministry of Defence
    • -Investigated the promoter and exonic variants OAS1 are associated with pregnancy, other reproductive performance and incidence of normal calving in indigenous and crossbred cattle.
    • -Discovered novel microRNAs (miRNAs) through NGS based analysis, which are directly or indirectly related to cellular thermo-tolerance in Indigenous and crossbreed cattle
