Rovers' managing director Derek Shaw knew United boss David Moyes when the pair were at Preston North End.
Bowyer told the Lancashire Telegraph: "Obviously Manchester United are only down the road and they have some talented players, ones I've seen growing up so I'm aware of them.
"If we can establish a link with them in terms of bringing players to give them experience in the Championship, it's a fantastic contact.
"Derek obviously had David at Preston and when we were in the run-in during last season I just asked if it would be possible to speak to him.
"Derek asked him and he said 'yes, no problem'. David was brilliant.
"He gave me half an hour of his time, he went through a list of things of, 'Are you doing this, are you doing that, this is what you might need to do'.
"The advice was invaluable to us in terms of what we did and how we went about it towards the end of the season."
