Two experiments were conducted to evaluate the effects of the level of corn dry distillers grains with solubles (CDDGS) supplementation on growing performance, blood metabolites, digestion characteris...
The goal of this research was to investigate the potential of hyperspectral Hyperion (EO-1) data to derive fractional cover of rangeland components using constrained linear spectral mixture analysis. ...
Resource stratification for ground-based and remotely-sensed methods of rangeland assessment is essential for locating appropriate sampling sites. This is particularly the case when site comparisons a...
Grazing lands in the United States consist of approximately 312 million hectares of federal, state, and private land. A recent review by the National Research Council indicates a need to collect comp...
This study uses Landsat data and Tasseled Cap Transformation green vegetation index (GVI) technique to assess the condition of rangeland resources in the Sahel region of West Africa. Three represe...
High soil bulk density and penetration resistance as an indication of soil compaction affect soil infiltration and runoff.
The accuracy of photogrammetry in determining snow depth in mountainous rangeland watersheds was evaluated on a 0.41-km2 subbasin of the Reynolds Creek Experimental Watershed, located in the Owyhee ...
High soil bulk density and penetration resistance as an indication of soil compaction affect soil infiltration and runoff. Overgrazed rangelands are under severe erosion risk because of soil compacti...
This paper focuses upon the incompatibility between poverty alleviation and environmental conservation and the solution to the incompatibility in an agro-pastoral area of China. The effects on income ...
This study was conducted to determine the annual variations in crude protein, crude cellulose, P, K, Ca and Mg contents, and the ratio of K/(Ca+Mg) of crested wheatgrass, subalpine brome, sheep fescue...
This study was conducted to determine annual variations in the below- and above-ground biomass, root/stem, stem, leaf and flower ratios of crested wheatgrass, subalpine brome, sheep fescue, junegrass,...
A seminomadic animal raising system, known as ''yaylacılık'' in Turkish, is one of the best ways of using upland rangelands, particularly in rough terrain regions. Three rangeland sites were...
Aerial photography acquired with unmanned aerial vehicles (UAVs) has great potential for incorporation into rangeland health monitoring protocols, and object-based image analysis is well suited for ...
The present study was undertaken to evaluate the effect of flushing of ewes with concentrate pellets just before the mating season on their nutrient utilization and reproductive performance on farms. ...
Malpura and Kheri ewes (76) in their late gestation, weighing 34.40 0.95 kg were randomly selected and divided into 4 groups of 19 each (G1, G2, G3 and G4). Ewes in all the groups were grazed on natur...
