I would say it is a baptism act rather than a birth act.
The translation is:
On January 30th, 1848, at 8am, Dominicus Rochus Mazza, son of Dominico and Maria Frasinetti (who are) married, was baptized by me, Prior Ferdinando Lusardi. Godfathers were Joseph Mazza and Antonia Mazza,
....(I can't read this)... daughter Augustina.
thankyou for the translation... definately the person I was looking for, this could prove very helpful with my continued research...I will head back to the Family research centre to find more relevant data.
