Bill, My simple mind wonders how much of the "10 pounds of forage" is water and any other non-digestible or other matter that is unable to be utilized. With processed, "high digestibility" feeds, LMB convert at about a 4:1 ratio. My SWAG is that only about 4 pounds of "natural" forage is digested...

Another factor that could play a huge part in weight gain is the amount of calories expended hunting natural forage. Chasing 300 (~1#) adult fatheads will burn FAR more calories than gulping down a 1# trout (arguably the ideal bass forage fish)
