Assessment of Sperm Viability in Extended Boar Semen during Long Term Storage at 15ËšC
Abstract:
A total of 24 ejaculates comprising 6 ejaculates from each of four trained healthy crossbred Hampshire boars of one to two years of age were selected for the present study. Semen was collected by Simple fist method to study the effect of Modena extender on quality of semen during preservation at 15ËšC up to 120 hours. The results revealed that the sperm motility, live intact acrosome, HOST-reacted spermatozoa, sperm membrane protein, sperm cholesterol level decreased significantly (PË‚0.01) with increase in hour of preservation. The highest conception rate (93.33%) was observed at immediately after extension and lowest conception (40%) was observed at 120 hours of preservation. In conclusion, the boar spermatozoa undergo several changes including diminished motility, viability and alterations in membrane permeability during long term storage at 15°C with Modena extender.
