Different feeding growth rates?

[Beccanin]

I'm just curious, but does the type of feed you give your snake effect how quick it grows? I know genetics affect the growth rates but has anyone noticed any difference between using rats/mice and 1 of the right size/2 of a smaller size?

Gram per gram it's all the same but it is easier to feed one prey vs multiples, more economical also.
