Effects of Melatonin and Dopamine Hydrochloride on Cryopreservation of Boar Spermatozoa
To provide reference data for the improvement of the composition of the diluent for cryopreservation of boar spermatozoa, the effects of different concentrations of melatonin and dopamine hydrochloride on abnormality, acrosomal integrity of frozen-thawed boar spermatozoa were analyzed. The results showed that 10 mmol/L melatonin or three doses of dopamine hydrochloride (0. 1 mmol/L, 1 mmol/L,10 mmol/L) could significantly improve abnormality, acrosomal integrity of frozen-thawed boar spermatozoa. It indicated that both of the two drugs deserved further extension and utilization to boar semen cryopreservation.
