Narrative:

As soon as I initiated the rotation for takeoff I had to immediately check my rotation because the nose wheel popped off of the ground. The airplane seemed very tail heavy. I then continued to rotate; but at a slight slower rate to 7.5 degrees to avoid striking the tail. I commented to the captain that I felt the trim was wrong. The climb profile was executed normally. 24 minutes after takeoff; received a new weight manifest that showed the new ZFW of 263.7 vs. 259.2; and increase of 4;500 pounds. The new takeoff trim setting was 2.8 vs. 3.0. New tog 317.8 vs. 313.3. Reported discrepancy to our dispatcher.
