    • Current Research Area
      (Co)variance components and genetic value estimation of animal, Disease resistance, Molecular characterization etc.

    Qualifications :

    • B.V.Sc & A.H., BCKV, Mohanpur, West Bengal, INDIA
    • M. Sc. (Animal Genetics & Breeding), NDRI, Karnal, INDIA
    • Ph.D. (Animal Genetics & Breeding), NDRI, Karnal, INDIA

    Major Research Accomplishments :

    • I worked in the projects related to “Genetic evaluation and improvement of Indian goat breeds (viz. Jamunapari and Jakhrana goats) for milk and/or meat production”. Genetic evaluation of different traits of interest (body weights, milk production traits etc.) was carried out in these goat breeds with an aim to improve the body weights and milk production through selective breeding. Similarly, my research involved on the genetic evaluation and improvement of production and reproduction traits of Muzaffarnagari sheep with an aim to improve the production and reproductive performance of sheep. Superior germplasm (sires) were produced at the farm level and supplied to various Govt./NGO’s for breed improvement programme in the field condition.
    • I was actively involved in the project entitled “Molecular analysis of major genes and quantitative trait loci influencing growth, reproduction and disease resistance traits in Indian goats”. We are trying to characterize quantitative loci that control production, reproduction, disease resistance and meat quality traits in Indian goats.
    • The studies of maternal effects on genetic evaluation of economic traits in goat and sheep breeds are another component of research and efforts have made to establish the role of maternal effects on different economic traits.
    • I also worked in the field of “Genetics of disease resistance with special reference to natural infection with gastro-intestinal nematode” in goat and sheep. Indicator traits for resistance to gastro-intestinal nematodes have been established in Indian goats and sheep.
    • I was also engaged to study the genetic variability of milk protein polymorphism for utilization in conservation as well as genetic improvement of Indian goat breeds for increasing both quality and quantity of milk production.
