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.
