Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.

All spinal nerves are mixed nerves (both motor and sensory).

What is loss If the anterior root of a spinal nerve is severed?

The anterior or ventral roots carry motor or efferent information from motoneurons in the anterior horn to muscles. This is as opposed to the dorsal roots that convey sensory or afferent informaiton from the periphery to the dorsal horns of the spinal cord. This is not to be confused with ventral rami that subserve intrinsic muscles of the back and neck. Therefore if a ventral root is severed or cut there would be a loss on motor function to muscles in the distribution of that root (called a myotome).
