Treviso led 16-15 at half-time, fly-half Francesco Mazzariol scoring a smart try near the posts after he had already kept pace with Jenkins by landing three penalties.
The last-minute surge was not enough to turn the game around but it did at least give rock-bottom Zebre a bonus point to show for their efforts, although they do drop to the foot of the table with
Treviso moving two points ahead of them.
"To score 48 points, score seven tries and concede none last week was very 3 0 Today:
Treviso 1.35pm Tomorrow: Montpellier Leicester, pleasing," said Anscombe.

Treviso responded with an excellent Benvenuti try.
Leicester withstood a fierce
Treviso comeback before breaking the shackles with 43 unanswered points in the last 28 minutes of the contest.
