Research Interests:

Some theoretical work in Animal Breeding usually in estimation or systems is continued. Bulk of work in recent years has been in applications of reproductive biology technologies into animal production and improvement schemes. In particular, the in vitro produced bovine embryo has many applications. An important application is in tropical dairying where in ova from high milk producing taurus breeds are fertilized with sperm from tropically adapted breeds or species of cow. Resulting heifers are ideal milk cows under a wide range of tropical conditions exibiting maximum heterosis and complementarity.
