one of the key factors in managing a rangeland is to determine the relative preference of its major plant species by thegrazing livestock. preference value of each plant species is affected by plant type, companion plants, availability byanimals, phenological stage, climate condition, and the livestock species. we investigated the grazing behaviour of anative goat (garizi) in the steppe rangela...

Reports of positive or neutral effects of grazing on plant species richness have prompted calls for livestock grazing to be used as a tool for managing land for conservation. Grazing effects, however, are likely to vary among different response variables, types, and intensity of grazing, and across abiotic conditions. We aimed to examine how grazing affects ecosystem structure, function, and co...

This study was conducted at Eldebeibat area, in South Kordofan State, Sudan. The aim of this study was to assess the role of competition on rangelands’ utilization on occurrence of conflicts between land’s users in the semi-arid areas of Eldebeibat, Sudan. Two target questionnaires were designed to collect data from two groups of land users namely nomadic pastoralists and sedentary farmers that...

Finding an optimal balance between livestock production and grazing impact on animal diversity is important for the development of sustainable grazing systems. This paper tests the hypothesis that extensification of grazing management enhances animal diversity. Similar treatments were applied over a period of three years to sites in the UK, France, Germany and Italy. There were three treatments...

Extensive livestock grazing even in unsuitable land has increasingly grown in most parts of semi-arid rangeland. Therefore, it is of paramount importance to identify suitable land for livestock grazing for optimum utilization while causing minimum impact to the environment. This paper adapted the schematic model based on the concepts presented by the Food and Agriculture Organization of suitabi...

Rotational grazing is commonly assumed to improve livestock distribution compared to continuous grazing, but little evidence supports this contention. Research was conducted on the effects of rotational grazing (RG) compared to continuous grazing (CC) on the preference of cattle for plant communities. Diffeant livestock densitiea in the RG treatments were created by varying the size of paddocka...

Many benefits have been obtained from rotational grazing, including management flexibility and livestock distribution, but long-term positive effects on plant and animal production have been inconsistent. The purpose of this case study was to investigate nutrient intake of animals in 2 production scale graxing treatments. The study site was the Texas Experimental Ranch located in Throckmorton C...

While toxins from aquatic cyanobacteria are a well-recognised cause of disease in birds and animals, exposure of grazing livestock to terrestrial cyanobacteria has not been described. This study identified terrestrial cyanobacteria, predominantly Phormidium spp., in the biofilm of plants from most livestock fields investigated. Lower numbers of other cyanobacteria, microalgae and fungi were pre...

In Wisconsin, the prevalence of dairy and livestock farming has led to questions about how animal agriculture affects the environment. As of 2003, managed grazing was practiced on 23 percent of Wisconsin dairy farms (Taylor and Foltz 2006). Many farmers who practice managed grazing (graziers) have observed environmental benefits resulting from this management system. What have scientific studie...

Soil degradation caused by overgrazing is a worldwide problem. The degradation of an overutilized area occurs mainly where animals prefer to spend extra time because of the attractants that are around gateways, water sources, along fences or farm buildings. High grazing pressure decreases plant density which results in changes of the botanical composition of a pasture. The effect that grazing h...
