Abstract This study determines which factors are associated with the use of rotational grazing and frequency Tennessee producers rotate cattle during summer months. Survey data were used to estimate an ordered response model sample selection. Most respondents grazing, most frequent schedule was rotating one two times per month. Factors including labor, capital, knowledge, water availability inf...

Ultrahigh stocking density (113,000 kg of beef per ha to as high as 1 million kg per ha) or mob grazing has been suggested to build soil, increase forage production and plant diversity, and improve grazing distribution compared to less intensive grazing systems. Experimental evidence does not completely support such conclusions. The overall focus of this research is based on the approach of bui...

Fermentation in the rumen of cattle produces methane (CH4). Methane may play a role in global warming scenarios. The linking of grazing management strategies to more efficient beef production while reducing the CH4 emitted by beef cattle is important. The sulfur hexafluoride (SF6) tracer technique was used to determine the effects of best management practices (BMP) grazing compared with continu...

Abstract DairyMod is a biophysical simulation model of the dairy pasture system. It has been designed to explore dairy pasture management and incorporates the principal rotational grazing management strategies that are used in Australia. It also includes full treatment of the fluxes of water and nutrients in the grazing system, and therefore it also has utility in analyzing changes in resource ...

The U.S. Department of Agriculture-Natural Resources Conservation Service has recommended domestic cattle grazing exclusion from riparian corridors for decades. This recommendation was based on a belief that domestic cattle grazing would typically destroy stream bank vegetation and in-channel habitat. Continuous grazing (CG) has caused adverse environmental damage, but along cohesive-sediment s...

Livestock face complex foraging options associated with optimizing nutrient intake while being able to avoid areas posing risk of parasites or disease. Areas of tall nutrient-rich swards around fecal deposits may be attractive for grazing, but might incur fitness costs from parasites. We use the example of dairy cattle and the risks of tuberculosis transmission posed to them by pastures contami...
