Modeling weather and stocking rate effects on forage and steer production in northern mixed-grass prairie
Stocking rate (SR) is the primary management factor that influences livestock gains, plant community changes and forage production, as well as economic returns for livestock producers. More effective stocking decision making by ranchers in the semi-arid northern mixed-grass prairie requires clearly understanding forage production and yearling steer weight gain (SWG) responses to SR and high wea...
متن کاملSeasonal temperature and precipitation effects on cow–calf production in northern mixed-grass prairie
Quantifying the effects of seasonal temperature and precipitation on cow–calf production on rangelands is challenging, as few long-term (420 yrs) studies have been reported. However, an understanding of how seasonal weather inconsistency affects beef production is needed for beef producers to better manage their herds on native rangelands to minimize enterprise risk with respect to climatic var...
متن کاملPredicting Nitrogen Content in the Northern Mixed-Grass Prairie
Forage quality and quantity are important factors affecting livestock production from grazing lands. ‘‘Greenness’’ has been proposed as an indicator of herbage quality in semiarid environments, particularly nitrogen (N) content. The objective of this study was to assess the potential of estimating N content of forage using dead:green ratios and accumulated growing-degreedays (AGDD). Standing cr...
متن کاملPrimary Productivity and Precipitation-Use Efficiency in Mixed-Grass Prairie: A Comparison of Northern and Southern US Sites
Precipitation-use efficiency (PUE) is a key determinant of aboveground net primary production (ANPP). We used long-term datasets to contrast ANPP and PUE estimates between northern (southeast Montana) and southern (north Texas) mixed-grass prairies. Effects of varying amounts and temporal distribution of precipitation on PUE were examined at the Montana site, using a rainout shelter and irrigat...
متن کاملDirect and Indirect Effects of Avian Predation on Grasshopper Communities in Northern Mixed-grass Prairie
The ecological interactions between grasshoppers, predators, and resources that can limit the population growth of grasshoppers are poorly understood. A number of Þeld experiments have shown that top-down control by avian predators can limit grasshopper populations, but the effects of avian predators on grasshopper populations can differ between years and between sites in the samehabitat. I con...
