“…Industry has embraced the adoption of using RFI data for bull purchases. Unfortunately, most research with RFI has been done in the feedlot, with minimal research being conducted in a grazing environment [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ] and even less in a rangeland environment [ 19 , 20 , 21 , 22 ]. A key finding of our prior research [ 21 ] conducted on late-season, low-quality rangeland with unsupplemented nonlactating 2-year-old cows was that LRFI cows lost less weight and body condition than did HRFI cows; however, we did not observe any differences in either daily travel distance or harvesting rate (bite rate) between HRFI and LRFI cattle.…”

The objective was to determine if low- or high-residual feed intake (LRFI or HRFI, n = 24 for each) Hereford × Angus cows on continuously or rotationally grazed rangeland altered their grazing behavior when provided a protein supplement in late autumn. Treatments included continuously grazed, control (CCON, n = 12); continuously grazed, supplemented (CTRT, n = 12); rotationally grazed, control (RCON, n = 12); and rotationally grazed, supplemented pastures (RTRT, n = 12). Cows in each treatment had grazing time (GT), resting time (RT), and walking time (WLK) measured for 2 years with accelerometers. Bite rate (BR) was also measured. Time distributions of GT and RT differed by year (p < 0.05), being influenced by colder temperatures in 2016. Cattle in 2016 spent more time grazing during early morning and late evening (p < 0.05) and rested more during the day (p < 0.05). In 2017, cattle in the CCON treatment walked more (p < 0.05) during early morning time periods than did the CTRT cattle, indicative of search grazing. All supplemented cattle had greater BR (p < 0.05) than control cattle in 2017. Cattle with increased nutritional demands alter grazing behavior in a compensatory fashion when grazing late-season rangelands.

Rangeland Wildlife Ecology and Conservation

View full text Add to dashboard Cite

Rangeland wildlife ecology and conservation is strongly influenced by domestic livestock systems. Domestic livestock production on rangelands in North America is dominated by ruminant livestock, with beef cattle being the largest industry. Rangeland ruminant livestock production systems are unique in that land/animal managers develop production systems that attempt to optimize the use of limited-nutrition forage bases. This involves the strategic selection of calving/lambing dates to coincide with forage resources and labor limitations. Likewise, the species, breed, and age of animal is selected to be productive in sometimes suboptimal nutrition and environmental conditions. In addition, the role of this industry in the conservation and enhancement of wildlife diversity and ecosystem services is important now and paramount in future management goals. Grazing systems that are unique to the needs of ecosystems are designed to enhance soils, vegetation, and wildlife diversity. In addition, understanding how wild and domestic animals utilize landscapes of varying topography is an ongoing area of research. Continued investigations into how animals use landscapes, grazing distribution/behavior, botanical composition of diets, and dietary strategies will be important in designing management approaches for all animals that are dependent on rangeland resources. The paradigm of sustainable management of livestock systems needs to view herbivory as a tool to manage vegetation for optimal biological integrity and resiliency. Only by the optimization of biological processes within plant communities on rangelands, will managers create systems that benefit both livestock and wildlife.
