I think it would be wildly different for different Mamono.

Devil Bugs and Large Mouses? Faster than humans, I would say. They probably are full grown when they are only a few years old.

Kobolds, Weresheep, Holstaur, Centaur...etc.? Their growth rate probably is something in between that of the related animal and that of a human being.

Long lived creatures like Dragons, Ryus, Mermaidsm, Demons...etc., probably grow at the same rate as humans.

Mandragoras probably grow at the rate as plants and need only a few months to become like the one in the profile.

Slimes' growth rate probably depend only in the amount of nutrients they get. The could grow to adulthood in a day if they got enough food.
