Are suckling pig feed and creep feed the same kind of feed?

I see many manufacturers write suckling pig feed (7 days - 35 days)

Divided into suckling pig feed, piglet feed, growing pig feed, and finishing pig feed

Is that so, is piglet feed the same as piglet feed?
---------------------
Now many feed manufacturers divide it more finely, requiring 5 stages or even 7 stages.
Generally, creep feed starts from 5-7 days to weaning, piglet feed from weaning to about 40 days, nursery feed to about 60 days
Then piglet, 30, 60 growing pig, 60-120 finishing pig feed 120-200
