Abstract

The present study was undertaken to determine the superovulatory response and embryo recovery in crossbred
cows treated with single dose of FSH dissolved in poly vinyl pyrrolidone (PVP). Nine crossbred cows were superovulated
using single dose of FSH dissolved in 30% PVP and fourteen crossbred cows were superovulated using FSH multidose
dissolved in saline. Donor cows were flushed non-surgically on day 7 after fixed time insemination with good quality semen,
embryos recovered, examined, graded and cryopreserved until transfer. There was no significant difference between the two
treatments of FSH in crossbred cows for number of corpus luteum, unovulated follicles, embryos recovered and transferable
embryos. The rate of transferable embryos obtained were 85.0% and 86.9% in crossbred cows treated with single dose of
FSH dissolved in PVP and multiple dose of FSH dissolved in saline respectively.
