WotLK profession skill bonus?

[OtongGG]

is there any bonus for first profession ? for example my first prof is skinning and second is leatherworking, because skinning is my first prof, is there any bonus in skill increasing, maybe double skill increasing rate every time you do skinning ? Or there is no such thing like that in wow and 1st and 2nd prof have same skill increasing rate?
