“…Beginning 2 wk after placing animals in pastures, 1 0 fresh individual fecal samples from cows were collected at nine biweekly intervals between mid-June and early October. Slides (25 x 75 mm) were prepared from fecal samples (Scott and Dahl 1980), and microhistological examination of slides followed Sparks and Malachek (1968). The contribution of forage classes to diets of each herbivore replicate was determined by converting microhistological frequency of occurrence to relative density (Fraker and Brischle 1944).…”

There exists considerable uncertainty whether differences between bison () and cattle (Bos taurus) should be exploited in natural area stewardship. Because foraging ecology may prescribe the fundamental relevance of either herbivore, we describe the foraging of bison and cattle on a northern mixed prairie natural area and discuss management implications. As generalist foragers, bison and cattle exhibited seasonal differences in selection for or against C"3 graminoids, C"4 grasses, forbs, and browse. Forty-eight hour in vitro dry matter digestibilities of C"3 graminoids and C"4 grasses were greater by bison than cattle, but equal digestive efficiencies were exhibited for forbs and browse. Dietary in vitro dry matter digestibility and crude protein differed little between herbivores. Cattle allocated more time to grazing than bison did during summer. Our study suggests that the relationship between feeding-time investment and forage patchiness is important in determining differences in diet choice between bison and cattle. In contrast to cattle, it appears that bison balance nutrient and time demands during the rut by consuming almost exclusively graminoids. Apparently, bison and cattle may achieve similar dietary quality through different foraging behavior. We suggest that specific scale-dependent programmatic conditions exist where either herbivore may be the most appropriate for natural area management.

“…Cover slips were placed on slides and edges were sealed with Permount mounting media (Santa Cruz Biotech, Santa Cruz, California). We viewed 10 fields/slide and about three fragments were visible per field of view at 1003 magnification (Scott and Dahl, 1980). The fragment nearest the ocular pointer in the microscope was identified.…”

“…The microhistological approach was used to identify fragments of plants in fecal material (Scott and Dahl, 1980). Dried fecal material was ground in a Wiley Mill using a 0.25-mm (60-mesh) sieve to obtain fragments of plants of similar size (Litvaitis et al, 1996).…”
