Abstract

The effect of gonadotrophin releasing hormone (GnRH) to augment semen production in six low and very low semen
producing imported Jersey bulls with normal libido were studied during the year 1999. Bulls were injected single dose of 200 mg GnRH
(Buserelin Receptal"' Hoechst) intramuscularly three hours ahead of semen collections. GnRH therapy did not show significant
beneficial effect on libido, reaction time and on other semen characteristics like pH, spermatozoa motility, sperm density, total
sperm concentration, spermatozoa viability and total abnormality of spermatozoa. The mean semen volume and spermatozoa
motility in stored semen increased significantly (P<0.05). It was concluded that though there was beneficial effect on semen volume
and motility with GnRH treatment, semen straw production was not improved.
