global warming and climate change have drawn special attention to soil and its potential for stable carbon sequestration. soils are the largest stores of carbon in terrestrial carbon cycle and contain about three times more carbon than vegetation cover and two times more than that of atmosphere. studying the effects of grazing on soil carbon storage is important because of the major role soil o...

Effects of applying Tasco-Forage, an Ascophyllum nodosum seaweed-based product prepared by a proprietary process, to endophyte (Neotyphodium coenophialum [Morgan-Jones and Gams] Glenn, Bacon, and Hanlin)-infected and endophyte-free tall fescue (Festuca arundinacea Schreb.) were studied in each of 3 yr (1995, 1996, and 1997) in Virginia and in 1996 and 1997 in Mississippi. There were 48 steers a...

Undi, M., Wilson, C., Ominski, K. H. and Wittenberg, K. M. 2008. Comparison of techniques for estimation of forage dry matter intake by grazing beef cattle. Can. J. Anim. Sci. 88: 693 701. Four techniques were compared for their ability to estimate forage dry matter intake (DMI) of grazing animals. In the Cage technique, 10 grazing cages were placed within each pasture, and forage inside and ou...

Two methods of determining diet botanical composition, microhistological (MH), and stable carbon isotope ratio (CR) analyses were used to determine botanical composition of ingesta and fecal grab samples in steers grazing rhizoma peanut-mixed tropical grass pastures. Three pastures were used over two grazing seasons, 1992 and 1993, in Brooksville, FL. A weighted-disc double-sampling technique w...

• Bee richness and abundance was higher in native grass pastures without cattle. Perennial grasses may provide some forage resources for bees. Honey bees were collected more commonly non-native pastures. Land sharing/sparing with perennial cattle can be ecologically positive. Most grasslands world-wide have been converted into various row crops agriculture pasture livestock foraging. This conve...

Eight beef steers fitted with esophageal (four steers/pasture) and 12 beef calves fitted ruminal and duodenal (six calves/pasture; beginning BW = 267 +/- 6 kg) cannulas grazed either midgrass prairie rangeland (excellent range condition; MIDGRASS) or plains bluestem (Bothriochloa ischaemum var. Plains) pasture (BLUESTEM) during mid-May, late June, mid-August, and mid-October of 1990 and 1991 in...

Introduction Biologists lack a great deal of information about wildlife in the Nebraska Sandhills, especially on private rangelands. For example, there is little knowledge about the small mammals of the area and their role in the ecosystem in which they live. Because only three percent of Nebraska is public land (Schneider et. al 2005), private land management is, by default, critical to the bi...

Reproductive wastage was investigated over two seasons in ten Merino flocks grazing pastures based on oestrogenic subterranean clover. Only 65 percent of ewes were served during the first 16 days of joining. Ovulation rates were low, averaging 1.13. Fertilization rates (73%) were low when compared with flocks unaffected by oestrogenic pastures. Embryonic mortality varied considerably between pr...

Tick-borne pathogens can cause serious problems in grazing cattle. However, little information is available on tick-mediated diseases in cattle grazing on mountains. Thus, this study aimed to understand the potential problems related to tick-borne diseases in grazing cattle through the investigation of prevalent tick-transmitted infections, and their associated hematological changes, in terms o...

To obtain specific information about cattle in extensive production systems, the usual labor intensive work done by farmer to find and visit herds large pastures can be replaced using UAVs. UAVs are capable of assessing traits cows, like distinguishing individuals postures. Although these detection cattle, do not represent resilience efficiency directly, may contain associated resilience. We pe...
