Influence of prostaglandin F2□ on preservability of Jamunapari buck semen

One hundred and forty four ejaculates were collected in artificial vagina from six Jamunapari bucks. After collection semen samples were split-diluted in EYC without (control) and with prostaglandin F2□ @ 4 μg/ml (treated) and stored at 4°C up to 72 hrs. The seminal characteristics, i.e. progressive motility, live sperm percentage, and abnormal percentages of acrosome, head and tail were evaluated at 72 hourly intervals. There were significant differences between control and prostaglandin F2□ treated samples for sperm motility, viability and head abnormality percentages at 24, 48 and 72 hrs of preservation. Prostaglandin F2□ was found to be good additive in terms of progressive motility, live sperm percentage, and sperm tail and acrosomal abnormality percentage and hence may be used in routine refrigeration preservation of buck semen.
