Abstract
Embryo transfer technology is an important biotechnological tool to produce more number of offspring
from genetically superior animals during their reproductive life. Application of exogenous gonadotropins
and knowledge of ovarian follicular dynamics are two very powerful tools that provide opportunities to
maximize the number of oocytes obtained from superior cows. Gonadotropin induced superovulation is the
basic and efficient method of obtaining multiple embryos from these genetically valuable females. However,
the superovulatory response (SOR) is highly unpredictable and variable between treatments thus affecting the
efficiency of the technology and limiting its practical application. Variability in ovarian response has been
attributed to various factors such as donor parity, production status, season, hormone preparations and their
dose etc., (Quaresma et al., 2003; Lee et ul. 2012; Vieira et al., 2014).
