There isn't a fixed timeslice due to preemption for interrupts, etc.  However, 
the default time slice is available as the kern.sched.quantum sysctl:

% sysctl -d kern.sched.quantum
kern.sched.quantum: Roundrobin scheduling quantum in microseconds

In the kernel it is stored as a static (private) variable in the scheduler 
implementation.
