In this investigation, the effects of enclosure, restal delayed grazing andcontinued grazing treatments on the production rate and vegetation cover were studied.Study area was SadrAbad pasture. After selecting three bands (1+1+1=3 hectare area) asthree treatments in the restricted and non restricted area, they were transected to threetransects. Then plots (1×2m2 ) were selected to measure the p...

To investigate the effect of restricted grazing time on behavior of Tan sheep on desert steppe, forty 4-months old male Tan sheep with an original body weight (BW) of 15.62±0.33 kg were randomly allocated to 4 grazing groups which corresponded to 4 different restricted grazing time treatments of 2 h/d (G2), 4 h/d (G4), 8 h/d (G8) and 12 h/d (G12) access to pasture. The restricted grazing times ...
Controversy has surrounded the possible differences in pasture production which result from grazing by cattle or sheep. Experiments conducted over the 1972-76 period show that pasture production under grazing by sheep is greater than under grazing by cattle under similar intensive managements. A change from sheep grazing to cattle grazing can cause a rapid deterioration in pasture production, w...

The objectives of this study were to compare visual observation and an electronic grazing time method and to evaluate the effects of nutritional plans on intake, grazing behavior and horizontal and vertical locomotion of young bulls in a tropical pasture. Thirty-nine Nellore young bulls with an average body weight of 345±9.3 kg kept in pasture were used. The experimental treatments consisted of...
The study of vegetation dynamics under grazed and non-grazed rangelands is one of the most important prerequisites for range improvement. In this research, vegetation composition and the vegetation functional groups were compared in an exclosure site (livestock excluded for six years) and grazed area in semi-steppe rangelands in Tehran province. Systematic random sampling technique through the...
The extent of rangeland is one of the most important characteristics of organic carbon uptake and storage in soil and plants. The present study investigates the indices of plant diversity and organic carbon storage in mountain pastures under grazing and 10-year enclosure in Asadabad. The rangeland is approximately 100 hectares and its rangelands are in good condition and are in the 2S class in ...
Protected areas have emerged as one of the most important and effective tools in the world for biodiversity conservation. Changing the use of natural lands, especially rangelands to protected areas, causes livestock grazing to be restricted in some of the grazing lands. These restrictions cause conflict between different natural land stakeholders. This study investigates the grazing management ...
Experimental farmlets at DairyNZ’s Prototype Farm near Hamilton were used to determine potential reductions in nitrous oxide (N2O) emissions from use of a nitrification inhibitor and a restricted grazing regime. A control farmlet was managed under a conventional rotational grazing regime, while a “tight nitrogen” farmlet was managed under a similar grazing regime to that on the control farmlet,...
