How to design probe specific hybridize with a specific targeted gene in Southern blot method?

I use DIG-11-dUTP label probe with specific targeted gene to detect in host genome. Host genome have a huge sequence that to date no information in data base. I cut the genomic DNA by restriction enzymes but after southern blot process my specific gene in the host genome does not show the signal band. I use chemilluminence (SDP star) substrate for alkaline phospatase, I do not use radioactive label 32P. Could anyone give me more ideas with this case?

Could you please post some gel pictures of your digested genomic dna and the blot. Maybe after seeing the picture we can get some ideas.
