MADRAS VETERINARY COLLEGE

DEPARTMENT OF ANIMAL GENETICS AND BREEDING


Genesis

The Department of Animal Genetics and Breeding established during 1949 is one of the oldest Departments of Madras Veterinary College. The M.V.Sc. degree programme was introduced during the year 1957 and Ph.D. programme in 1978. This was the first Department of Madras Veterinary College recognized by the University of Madras for pursuing Ph.D. programme. The Department has a well-equipped Cytogenetics Laboratory, Biometrical and Computer Laboratory, Molecular Genetics Laboratory and Frozen Semen Bank. Besides teaching undergraduate and postgraduate students, the faculty and PG students take up research work in the frontier areas of biometrical genetics, cytogenetics, molecular genetics, gamete research and cryopreservation of gametes.
