For an in-house application, we were using the following code UIDevice+serialNumber to get the device serial number.
However, it seems that with iOS 8, the registry key "IOPlatformSerialNumber" is empty.
Can the serial number be obtained any other way?

There are currently floating solutions around abusing the .mobileconfig, but they add other problems due their nature.

Abusing the underlying march port to get the device serial number as replacement of the UUID is not the solution. Same now for abusing the mobile config and guess how long that will work.
You have plenty of decent ways to handle any situation where you used device identification before. Especial in an enterprise environment where you have cryptography and MDM is absolutely no point to track a device like this.
