Can the daily ' mucking out ' material from my stables be used . this would be aprox 50-60 Kgs of horse manure plus an additional 50-60 Kgs of urine soaked straw. Does the urine soaked straw pose a problem for a digester.

Is there any info about how much methane this much straw will generate.

Yes. A good source of information for farm-scale operations can be found at US EPA's website. In particular, check out their handbook and FarmWare software.
