Nutrition of grazing cattle. 4. Selectivity exhibited by grazing cattle

Abstract

A comparison was made between the percentages of protein, phosphorus and calcium in total available pasture and the percentage of these constituents in the pasture representative of that selected by grazing cattle. The two pastures examined were an Axonopus affinis and a Paspalum dilatatum dominant pasture. For both pastures the selected pasture contained about 50 per cent. more protein and about 30 per cent. more phosphorus than the total available pasture. Calcium levels in the selected pasture were comparable with those in the total available pasture.
