To determine the species composition of the diet of free-ranging cattle... to estimate the most important components of the diet… (and) to determine the digestibility and nitrogen content of plants regularly grazed by cattle (pp. 29).
Type of Study:
Natural history/natural experiment
Cattle were seen to eat 26 species of plants, while only 19 species were identified from microscopic examination of cattle faeces. A further 28 species examined in the field showed signs of grazing...Common Poa australis spp. agg. tussocks were of low digestibility and nigrogen content (pp. 29).
Experimental determination of selective grazing by cattle of alpine flora. Cattle prefer the snowgrasses and alpine forbs, and avoid the taller shrubs.

Bogong High Plains, Australian Alpine National Park, Victoria, Australia
Response variable :
Number of plant species grazed by cattle and cover abundance of each, presence/absence of species in cow pat, nitrogen content (dry matter basis), in vitro organic matter digestibility.
ca. 20 cow pats analysed from 10 cows; digestibility analysed in 2 sampless of 16 plant species; nitrogen content analysed in 9 plant species.
Alpine grassland, open heathland and closed heathland.
