After a pre-flight inspection, the pilot taxied the airplane to runway 36. During the takeoff roll at 70 knots, the pilot began rotation. At 75 knots, the nose wheel lifted off the runway, and from the west, a deer crossed in front of the airplane. The airplane's left wing struck the deer, and the pilot aborted the takeoff. The pilot then taxied the airplane back to the flight line. The airport did not have a perimeter fence around it that would prevent deer from entering the runway environment.
