Marcell Coetzee scored four tries as Ulster romped to another big victory against Pro14 Conference A bottom side Zebre.
The South African back row grabbed a first half hat-trick and Stewart Moore also crossed as the province secured the bonus-point before the break.
The scores kept coming after the interval with Bill Johnston, Luke Marshall, Coetzee, debutant Ethan McIlroy and Dave Shanahan heaping more misery on Zebre who registered tries from Pierre Bruno and Nicolo Casilio.
The result maintains Ulster's winning start to the season as they continue to pull away from the rest of the pack with Leinster at the top of Conference A.
The province are now 19 points in front of third-placed Ospreys and have taken four bonus-points from their opening six games.
Irrepressible Coetzee leads Ulster charge
Coetzee has scored in every game he has played this season, and with a raft of the league's top players currently on international duty the Springbok has looked a cut above most opposition.
The gulf in class was clearer than ever, with the number eight an unstoppable pick-and-go force, registering his first try inside seven minutes.
For their part Zebre looked lively in attack in the opening quarter, and got back on level terms via a stunning finish from Bruno, who somehow managed to maintain control of the ball after it bounced between a crowd of players.
However the score was no more than respite from the Ulster onslaught, as the province went back ahead via Coetzee and their most trusted weapon: the driving maul.
After Moore crossed following Michael Lowry's charge down and offload, Coetzee completed the hat-trick four minutes from the interval from yet another line-out maul.
