  Magneto-optical traps (MOTs) based on the $626\;{\rm nm}$, $136\;{\rm
kHz}$-wide intercombination line of Dy, which has an attractively low Doppler
temperature of $3.3\;\mu{\rm K}$, have been implemented in a growing number of
experiments over the last several years. A challenge in loading these MOTs
comes from their low capture velocities. Slowed atomic beams can spread out
significantly during free-flight from the Zeeman slower to the MOT position,
reducing the fraction of the beam captured by the MOT. Here we apply, for the
first time in a Dy experiment, a scheme for enhancing the loading rate of the
MOT wherein atoms are Zeeman-slowed to a final velocity larger than the MOT's
capture velocity, and then undergo a final stage of slowing by a pair of
near-detuned beams addressing the $421\;{\rm nm}$ transition directly in front
of the MOT. By reducing the free-flight time of the Zeeman-slowed atomic beam,
we greatly enhance the slowed flux delivered to the MOT, leading to more than
an order of magnitude enhancement in the final MOT population.
