in arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. a study was done to analyze the effects of grazing on plant species diversity and plant functional types‘ (pfts) diversity of arid and semi-arid rangelands. we analyzed plant richness and diversity data from 75 sa...

Since the halophytes species have an important role in such ecosystem balance and they have been grazed by livestock as supplementary forage, the awareness of livestock's desire to grazing and their preference values of these species is of high priority. Regardless of the importance of halophyte species in the livestock feeding in Iran, there is less published research on the livestock grazing ...

the effects of different grazing intensities on the above and underground biomass of twospecies festucaovina l. and alopecurustextilisboiss. in the north sabalan rangelands (in shabil) were investigated. sampling on the light, medium and heavy grazing intensities in the flowering stage (the second half of june 2013) were performed. initially, from a 90-meter transects perpendicular to the slope...

Mycorrbizal symbiosis is critical to growth of many warmseason prairie grass seedlings, but its effect on regrowth of rbizomes has not been determined. As forage species, the effect of grazing on the symbiosis is also important. when the impact of mycorrbizae on regrowth of Andropogon germ&i Vit. rhizomes was assessed, A. germ& rhizomes collected from the field and grown with mycorrbizal inocul...

Worldwide there are between 10 and 11 million hectares of coconuts. With the marked fluctuations and long term decline in copra and coconut oil prices the integration of livestock and coconuts is economically increasingly attractive. Traditionally used for weed control in plantations so that coconuts could be located, cattle (and sheep and goats) are increasingly seen as important parts of the ...

Tissue nutrient supply may be synchronized with endogenous physiological rhythms to optimize animal and human health. Glucose tolerance and insulin sensitivity have endogenous rhythms that are not essentially dependent on food type and eating. Human glucose tolerance declines as day comes into night. Based on such evolutionary findings, large evening meals must be avoided to reduce risks of vis...

investigation of the grazing behavior of grazing animals on the rangeland is one of the basic necessities of grazing management in different climatic regions. the current study with the aim of exploring the grazing behavior of makuyi sheep breed was conducted in the mountainous rangelands of kelid daghi of jolfa as representative rangelands for makuyi sheep breed dispersion in east azerbayjan p...

Rangelands cover approximately 85% of Kenya’s land mass and is a major resource for livestock farming with a considerable potential to mitigate climate change, yet these lands are stressed differently by various management. Our study aimed at determining the influence of grazing management systems (rotational, continuous and ungrazed) on soil organic carbon stocks in Yoani ranch located in the ...
