A 2-yr grazing experiment was conducted to assess the effects of grazing management on cattle distribution and pasture and stream bank characteristics. Six 12.1-ha cool-season grass pastures in central Iowa were allotted to 1 of 3 treatments: continuous stocking with unrestricted stream access (CSU), continuous stocking with stream access restricted to 4.9-m-wide stabilized crossings (CSR), or ...

Livestock grazing practices in rangelands are being recognized as management tool for environmental protection and increased livestock productivity. Continuous grazing has been largely reported to reduce pasture productivity and increase environmental degradation. Rotational grazing is an alternative to continuous grazing and is considered to reduce negative environmental effects and provide qu...

'Surrey' ryegrass (Lolium multiflorum Lam.) has produced well in clipping yield trials across Louisiana, but yield trials do not always predict how well the forage supports performance under grazing conditions. This trial compared Surrey ryegrass with 'Marshall' ryegrass grazed continuously or rotationally. Two pastures of Surrey and two pastures of Marshall that had been subdivided into six pa...

Activities of transhumance ongoing have been mostly carried out in alpine pastures for centuries in Turkey. These pastures used unconsciously have faced to the danger of extinction. In order to implement improvement plans in the mentioned areas, qualitative and quantitative characteristics of pastures should be determined. This study was conducted in the mowed and grazed pastures in alpine zone...

Grazing systems may alter botanical composition and productivity of grasslands through differential use in time, space, or intensity. Seven simulated grazing treatments were applied six years in eastern Montana, USA to determine effects on plant community composition and standing crop. Treatments were moderate stocking (28.8 AUD ha 1 year ) of cattle using 3-pasture summer rotation, season-long...

grazing management plays an important role in the continuous and economicutilization of pastures. proper grazing management is a main factor for the accumulation ofplant litter which reduces soil erosion and increase the soil permeability to keep moremoisture in the soil. in current study, the effect of three different grazing intensities (low,moderate and high) along with the grazing gradient ...

In 1858 H. S. Thompson, writing in the “Journal of the Royal Agricultural Society”, quoted an ancient Persian proverb, “The sheep has a foot of gold, and turns to gold whatever it touches”, and wrote that, although at first he agreed with the proverb, he rapidly became dissatisfied with it. In his experience-sustained yheavystockifig-w? sheep caused pastures to deteriorate. In my opinion his im...

Four hundred thirty-two yearling steers grazing tall fescue pastures were used to evaluate the effects of fescue cultivar and dried distillers grains (DDG) supplementation during the grazing phase on available forage, grazing gains, subsequent finishing gains, and carcass characteristics. Fescue cultivars evaluated were highendophyte ‘Kentucky 31’ and low-endophyte ‘Kentucky 31,’ ‘HM4,’ and ‘Ma...

The objective of the present experiment was to describe the sward canopy structures of 3 different wheat (Triticum aestivum L.) pastures and relate them to short-term herbage intake rate and foraging dynamics by steers. Pastures were sampled for leaf and stem fractions at the bottom, middle, and top canopy strata. Sward surface heights and tiller and bulk densities were measured. Herbage was se...
