overgrazing and inappropriate use of taleghan rangelands has led to poor and very poor condition for almost all vegetation types. taking the importance of rangelands in forage production and other benefits into consideration, management of these rangelands and improving their condition seems essential. the present research was conducted using data integration of vegetation, condition, slope, so...

Infiltration rate of water into the soil depends on the factors such as rock and litter cover, canopy cover, rainfall intensity, coarse material, land slope, soil texture and amount of initial soil moisture. The most important factors that are effective in the water infiltration rate of rangelands are livestock trampling and vegetation reduction due to the overgrazing. In present study, through...

The need to feed livestock of herdsmen necessitates their migration from their communities due to inadequate pastures to other communities and this has led to the trespass of these pastoralists to the farmlands of local agriculturalists and destruction of their crops thereby leading to conflict. This study therefore analyses the causes, evolution, dynamics and solutions to the conflicts generat...

Numerous factors affect livestock production and productivity. In this chapter we will address those that are of paramount importance: climate, nutrition, and health aspects. In initial section we will review the effects of climate on livestock productivity and provide examples of livestock adaptation to climate constraints such as the Bos indicus cattle breeds adapted to hot weather and the fa...

To determine association of grassland with parasitic diseases of livestock in Bangladesh, the 'Tracer' animals (two cow calves and two goats) were released for a month in a grassland used for communal grazing of livestock near school premise in Kanthal, Trishal, Mymensingh, Bangladesh. After slaughtering of the tracer animals, their gastrointestinal tract examination revealed six species of nem...

Changes in commodity pricing and environmental concerns are changing animal agriculture throughout the United States. Adopting multispecies grazing as an alternative production system could result in improved forage utilization, increased animal performance, and reduced production costs, and thereby improve the financial stability of livestock operations. This study focused on the Silver Spur R...

Grazing represents one of the most common disturbances in drylands worldwide, affecting both ecosystem structure and functioning. Despite the efforts to understand the nature and magnitude of grazing effects on ecosystem components and processes, contrasting results continue to arise. This is particularly remarkable for the biological soil crust (BSC) communities (i.e., cyanobacteria, lichens, ...

Despite overall increased production in the last century, it is critical that grazing production systems focus on improving beef and dairy efficiency to meet current and future global food demands. For livestock producers, production efficiency is essential to maintain long-term profitability and sustainability. This continued viability of production systems using pastureand range-based grazing...

Comparisons of stocking rates across sites can be facilitated by calculating grazing pressure. We used peak standing crop and stocking rates from six studies in the North American Great Plains (Cheyenne, Wyoming; Cottonwood, South Dakota; Hays, Kansas; Nunn, Colorado; Streeter, North Dakota; and Woodward, Oklahoma) to calculate a grazing pressure index and develop relationships for harvest effi...

Extensive livestock production has been Mongolia’s major industry for centuries and traditional nomadic herding lifestyle and Mongolia’s expansive rangelands sustain this industry. After the democratic election and economic liberalization in 1992, formerly state-owned collectives were disbanded and Mongolia’s livestock population was privatized. There was no longer a state institution to formal...
