Fertility - Dual Video of Untreated & Treated Bull Semen - 2006

Semen straws were thawed as per usual. One straw (the “Treated Sample”) was placed on a Tri-Vortex Disc for 3 min before placing specimens on a glass slide for microscopy. An ocular video camera was inserted into the microscope, and videos of each slide were recorded over a 7 hour period – at intervals of 30min between successive video clips. The video on the Right was for the semen sample that was treated on a Tri-Vortex disc. 
With approx 1000 cows that were AI’ed and conceptions confirmed via ultrasound, we could show that we improved conceptions rates by more than 50% – a result that was quite spectacular.
