Gloucester 23-10 Zebre
The champions got their campaign off to a winning start but it wasn't plain sailing as they went off the boil in the second half at Kingsholm.
Gloucester raced in to a 23-0 lead at half-time but the visitors fought back bravely to win the second half 10-0.
Henry Purdy opened the scoring in the seventh minute after Billy Burns, Callum Braley and Ross Moriarty laid the groundwork in the build-up.
Moriarty barged over from close quarters shortly afterwards before Burns added two penalties to give the Cherry and Whites an 18-0 lead by the half-hour mark.
Stevie McColl then rounded off a superb team effort shortly before half-time but Gloucester failed to kick on and couldn't notch their bonus-point try in the second half.
Instead, Zebre took control of proceedings and they were rewarded with a penalty try after Gloucester infringed at a scrum close to their try-line.
Edoardo Padovani added the extras as well as a penalty in the 58th minute which was the last time points were scored in this clash.
