not true <strong>of</strong> the 'Ayoming, Utah and Nevada studizs referred ~o above
and shown in Table 1 <strong>of</strong> Dr. Grandy's t2stirnony, as these studies based
the lamb count on lambs docked. Gee, et a1 . , however, also calsolat2d
post-docking loss2s to predators and if pre-docking losses are
eliminated the percentage <strong>of</strong> lamb losses to predators for the cized
states are reduced to 9.2 percent for Wyoming, 11 percent for Utah
and 14.8 percent for Nevada.
