Abstract
Several new reproductive techniques have been developed
which are used as aids to augment the reproductive eficiency
of a superior female to the maximum. Hormonal induction
of multiple ovulations followed by non-surgical collection
of embryos and their tralasfer to recipients is widely used.
Assessment of superovulatory response in a donor cow by
rectal palpation of ovaries is the conventional technique but
diagnosis of ovarian structures by rectal palpation is not
possible in about 20% of cases (Grunert and BerchtoPd 1982)
and there are always chances for misintelpretatio~liC. ompared
to manual palpation, ultrasonography permits a more precise
estimation of the number as well as the size of the ovarian
structures (Hanzen et al. 2000).
