The incompatibility of controlled selective grazing systems with farmers’ needs

Journal of the Grassland Society of Southern Africa, 1992
Since extension inputs, subsidy schemes and even legislation over several decades were unable to stem the veld deterioration in southern Africa, a renewed attempt was made to identify the causes of the non-adoption of recommended veld management practices. The hypothesis that controlled selective grazing (CSG) as a recommended system of veld management

Graze: A model of selective grazing by beef animals

Agricultural Systems, 1987
Abstract A dynamic simulation model has been developed that relates beef animal performance to environment, management practices and selective grazing of pastures. Daily measures of pasture quality and availability are maintained. Measures of the animal's physiological weight and age are computed at 15-min intervals or less, and body composition ...

Selective grazing by the mud snail Ilyanassa obsoleta

Oecologia, 1982
Mud snails (Ilyanassa obsoleta) starved for 48 h were allowed to feed on sediments in laboratory microcosms. Sediment cores sliced at 2 mm intervals were compared to snail stomach contents for per cent carbon and nitrogen, plant pigment contents and species composition of benthic diatoms.
