The selective grazing behaviour of Mongolian sheep and Mongolian cattle during 24-hour period was observed in spring,summer,autumn,and winter respectively.

Comparison study on selective intake behavior of sheep at different stocking rates in stipa breviflora desert steppe.;

The thesis on the ground of reading many domestic and overseas literatures analyzed and discussed the study summarize of grazing behavior of sheep by these facts,which were grazing behavior,grazing behaviors parameters and selective intake.

In the research, the intake selectivity of Alpaca on pasture was studied by using the nalkanes of plant.

Research advances in diet selection mechanisms of grazing herbivores;

Intake mass and diet selection are important components of animal foraging behavior, which can describe animal s grazing efficiency or currency.

We carried through primary research of foraging behavior and diet selection of sheep and foraging strategies under foraging sequences in plots with different species richness through measure of grassland vegetation and observing and recording foraging behavior of herbivores.
